Merge branch 'main' of https://git.kevlarai.com/ClassroomCopilot/supabase

- Replace legacy directory structure (api/, db/, functions/, logs/, pooler/) with
  single docker-compose.yml based self-hosted setup
- Add selfhosted-supabase-mcp TypeScript MCP server for database management
- Add .dockerignore for Docker build context
- Update .gitignore to exclude .env files, volumes/, backups, logs

+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+### Added
+
+- **HTTP Transport Mode**: Run MCP server in HTTP mode for Docker/Kong integration
+  - Express-based HTTP server with Streamable HTTP Transport
+  - Configurable CORS, rate limiting, and request timeouts
+  - Health check endpoint for container orchestration
+- **JWT Authentication Middleware**: Validate Supabase JWTs in HTTP mode
+- **Privilege-Based Access Control**: Role-based tool access (regular, privileged)
+  - `service_role`: Access to all tools
+  - `authenticated`/`anon`: Access to regular tools only
+- **24 New Database Introspection Tools**:
+  - Schema: `list_table_columns`, `list_indexes`, `list_constraints`, `list_foreign_keys`, `list_triggers`, `list_database_functions`, `list_available_extensions`
+  - Security: `list_rls_policies`, `get_rls_status`, `get_advisors`
+  - Definitions: `get_function_definition`, `get_trigger_definition`
+  - Performance: `get_index_stats`, `get_vector_index_stats`, `explain_query`
+  - Extensions: `list_cron_jobs`, `get_cron_job_history`, `list_vector_indexes`
+  - Edge Functions: `list_edge_functions`, `get_edge_function_details`, `list_edge_function_logs`
+  - Storage: `get_storage_config`, `update_storage_config`
+  - Logs: `get_logs`
+- **Bun Runtime**: Migrated from Node.js/npm to Bun for faster builds and execution
+- **Comprehensive Test Suite**: 13 test files with 240+ passing tests
+- **Docker Integration**: Dockerfile and Docker Compose configuration for self-hosted Supabase stacks
+
+### Changed
+
+- `execute_sql` now requires `service_role` JWT in HTTP mode (privileged tool)
+- Replaced `package-lock.json` with `bun.lock`
+
+### Removed
+
+- **`get_anon_key` tool**: Removed to prevent exposure of sensitive API keys through MCP
+- **`get_service_key` tool**: Removed to prevent exposure of sensitive API keys through MCP
+
+### Security
+
+- Removed tools that exposed API keys (`get_anon_key`, `get_service_key`)
+  - **Rationale**: MCP tools can be called by any connected client. Exposing API keys through MCP creates a security risk where keys could be extracted by malicious or compromised MCP clients. The anon key and service role key are already available to the server at startup via environment variables or CLI arguments - there's no legitimate use case for retrieving them via MCP during runtime.
+- Added privilege-based access control to restrict sensitive operations to `service_role` only
+- JWT authentication enforced for all HTTP mode requests

+# Self-Hosted Supabase MCP Server - Implementation Plan
+
+This plan outlines the steps to build the minimal self-hosted Supabase MCP server based on `migration_notes.md`.
+
+## Progress Tracking
+
+-   [x] Project Setup (package.json, tsconfig.json, dependencies, directories)
+-   [x] Bun Migration (replaced Node.js/npm with Bun runtime)
+-   [x] Define Core Types (`src/types/`)
+-   [x] Implement `SelfhostedSupabaseClient` (`src/client/`)
+    -   [x] Basic connection (`@supabase/supabase-js`)

+
+## Overview
+
+This project provides a [Model Context Protocol (MCP)](https://github.com/modelcontextprotocol/specification) server designed specifically for interacting with **self-hosted Supabase instances**. It bridges the gap between MCP clients (like IDE extensions) and your local or privately hosted Supabase projects, enabling database introspection, management, and interaction directly from your development environment.
+
+This server was built from scratch, drawing lessons from adapting the official Supabase cloud MCP server, to provide a minimal, focused implementation tailored for the self-hosted use case.
+
+## Purpose
+
+The primary goal of this server is to enable developers using self-hosted Supabase installations to leverage MCP-based tools for tasks such as:
+
+*   Querying database schemas and data.
+*   Managing database migrations.
+*   Inspecting database statistics and connections.
+*   Managing authentication users.
+*   Interacting with Supabase Storage.
+*   Generating type definitions.
+
+It avoids the complexities of the official cloud server related to multi-project management and cloud-specific APIs, offering a streamlined experience for single-project, self-hosted environments.
+
+## Features (Implemented Tools)
+
+Tools are categorized by privilege level:
+- **Regular** tools are accessible by any authenticated Supabase JWT (`authenticated` or `service_role` role).
+- **Privileged** tools require a `service_role` JWT (HTTP mode) or direct database/service-key access (stdio mode).

+
+### About `supabase_migrations.schema_migrations`
+
+The `list_migrations` and `apply_migration` tools rely on the `supabase_migrations.schema_migrations` table. This table is **created and managed by the Supabase CLI** — it is not part of the MCP server itself.
+
+**How the table is created:**
+
+The table is automatically created when you initialise or run migrations using the Supabase CLI:
+```bash
+supabase db push        # pushes local migrations to a remote database
+supabase migration up   # applies pending local migration files
+```
+
+If you have never run the Supabase CLI against your database, the table will not exist and `list_migrations` will return an error. You can create it manually with:
+```sql
+CREATE SCHEMA IF NOT EXISTS supabase_migrations;
+CREATE TABLE IF NOT EXISTS supabase_migrations.schema_migrations (
+    version text NOT NULL PRIMARY KEY,
+    name    text NOT NULL DEFAULT '',
+    inserted_at timestamptz NOT NULL DEFAULT now()
+);
+```
+
+**Schema difference vs. official Supabase:**
+
+The Supabase cloud platform tracks additional columns (e.g. `statements`, `dirty`). This MCP server uses the minimal schema (version + name + inserted_at) that is compatible with the Supabase CLI's local-development workflow. If your existing table has extra columns they are simply ignored.
+
+## Setup and Installation
+
+### Installing via Smithery
+
+To install Self-Hosted Supabase MCP Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@HenkDz/selfhosted-supabase-mcp):
+
+```bash
+npx -y @smithery/cli install @HenkDz/selfhosted-supabase-mcp --client claude
+```
+
+### Prerequisites
+
+*   [Bun](https://bun.sh/) v1.1 or later (replaces Node.js/npm — used for runtime and builds)
+*   Access to your self-hosted Supabase instance (URL, keys, and optionally a direct PostgreSQL connection string).
+
+### Steps
+
+1.  **Clone the repository:**
+    ```bash
+    git clone <repository-url>
+    cd selfhosted-supabase-mcp
+    ```
+2.  **Install dependencies:**
+    ```bash
+    bun install
+    ```
+3.  **Build the project:**
+    ```bash
+    bun run build
+    ```
+    This compiles the TypeScript source to JavaScript in the `dist` directory.
+
+## Configuration
+
+The server requires configuration details for your Supabase instance. These can be provided via command-line arguments or environment variables. CLI arguments take precedence.
+
+**Required:**
+
+*   `--url <url>` or `SUPABASE_URL=<url>`: The main HTTP URL of your Supabase project (e.g., `http://localhost:8000`).
+*   `--anon-key <key>` or `SUPABASE_ANON_KEY=<key>`: Your Supabase project's anonymous key.
+
+**Optional (but Recommended/Required for certain tools):**
+
+*   `--service-key <key>` or `SUPABASE_SERVICE_ROLE_KEY=<key>`: Your Supabase project's service role key. Required for privileged tools and for auto-creating the `execute_sql` helper function on startup.
+*   `--db-url <url>` or `DATABASE_URL=<url>`: The direct PostgreSQL connection string for your Supabase database (e.g., `postgresql://postgres:password@localhost:5432/postgres`). Required for tools needing direct database access (`apply_migration`, Auth tools, Storage tools, `pg_catalog` queries).
+*   `--jwt-secret <secret>` or `SUPABASE_AUTH_JWT_SECRET=<secret>`: Your Supabase project's JWT secret. Required when using `--transport http` and needed by the `verify_jwt_secret` tool.
+*   `--tools-config <path>`: Path to a JSON file specifying which tools to enable (whitelist). If omitted, all tools are enabled. Format: `{"enabledTools": ["tool_name_1", "tool_name_2"]}`.
+
+**HTTP transport options (when using `--transport http`):**
+
+*   `--port <number>`: HTTP server port (default: `3000`).
+*   `--host <string>`: HTTP server host (default: `127.0.0.1`).
+*   `--cors-origins <origins>`: Comma-separated list of allowed CORS origins. Defaults to localhost only.
+*   `--rate-limit-window <ms>`: Rate limit window in milliseconds (default: `60000`).
+*   `--rate-limit-max <count>`: Max requests per rate limit window (default: `100`).
+*   `--request-timeout <ms>`: Request timeout in milliseconds (default: `30000`).
+
+### Important Notes:
+
+*   **`execute_sql` Helper Function:** Many tools rely on a `public.execute_sql` function within your Supabase database for SQL execution via RPC. The server attempts to check for this function on startup. If it's missing *and* a `service-key` *and* `db-url` are provided, it will attempt to create the function automatically. If creation fails or keys aren't provided, tools relying solely on RPC may fail.
+*   **Direct Database Access:** Tools interacting directly with privileged schemas (`auth`, `storage`) or system catalogs (`pg_catalog`) generally require `DATABASE_URL` to be configured.
+*   **Coolify / reverse-proxy deployments:**
+    *   The `DATABASE_URL` must use the internal hostname reachable from wherever the MCP server process runs, not the public-facing domain.
+    *   An `ECONNRESET` error during startup means the `DATABASE_URL` cannot be reached from the server's network context.
+    *   The server will still start successfully and all tools that don't require a direct DB connection will continue to work normally.
+
+## Security
+
+### HTTP transport (recommended for remote access)
+
+When running with `--transport http`, the server enforces:
+- **JWT authentication** on all `/mcp` endpoints using your `SUPABASE_AUTH_JWT_SECRET`.
+- **Privilege-based access control (RBAC)** — the `role` claim in the JWT determines which tools are accessible:
+  - `service_role`: Full access (all tools including privileged ones).
+  - `authenticated`: Regular tools only.
+  - `anon`: No tool access.
+- **Rate limiting** — configurable request rate limit per IP address.
+- **CORS** — configurable allow-list of origins (defaults to localhost only).
+- **Security headers** — `X-Content-Type-Options`, `X-Frame-Options`, `Strict-Transport-Security`, etc.
+- **Request timeouts** — configurable timeout to prevent resource exhaustion.
+
+### Stdio transport (local development)
+
+Stdio mode has **no authentication** — all tools (including privileged ones) are accessible. It is intended for trusted local clients only (e.g., an IDE extension running on your local machine). A warning is printed on startup when this mode is used.
+
+### Password handling for auth user tools
+
+`create_auth_user` and `update_auth_user` accept a plain-text password from the MCP client, then immediately hash it with **bcrypt** (via PostgreSQL's `pgcrypto` extension: `crypt($password, gen_salt('bf'))`) before storing it in `auth.users`. The plain-text password is never stored. Passwords are passed as query parameters (not string-interpolated into SQL), preventing SQL injection.
+
+> **Note:** The password travels over the MCP transport in plain text between the MCP client and server. This is inherent to the MCP protocol interface and unavoidable at this layer. Use the HTTP transport with TLS termination (e.g., behind Kong/nginx) for network protection.
+
+### SQL execution security
+
+All database operations in the MCP server use parameterized queries (`$1`, `$2`, ...) to prevent SQL injection. The `execute_sql` tool is an intentional exception — it executes arbitrary SQL by design (it is the tool's purpose). This tool is restricted to `service_role` privilege level to limit exposure.
+
+## Usage
+
+### Stdio mode (local MCP clients)
+
+Run the server using Bun, providing the necessary configuration:
+
+```bash
+# Using CLI arguments (stdio mode — default)
+bun run dist/index.js --url http://localhost:8000 --anon-key <your-anon-key> \
+  --db-url postgresql://postgres:password@localhost:5432/postgres \
+  --service-key <your-service-key>
+
+# Example with tool whitelisting via config file
+bun run dist/index.js --url http://localhost:8000 --anon-key <your-anon-key> \
+  --tools-config ./mcp-tools.json
+
+# Or configure using environment variables and run:
+# export SUPABASE_URL=http://localhost:8000
+# export SUPABASE_ANON_KEY=<your-anon-key>
+# export DATABASE_URL=postgresql://postgres:password@localhost:5432/postgres
+# export SUPABASE_SERVICE_ROLE_KEY=<your-service-key>
+bun run dist/index.js
+```
+
+### HTTP mode (Docker / remote access)
+
+```bash
+bun run dist/index.js \
+  --transport http \
+  --port 3100 \
+  --host 0.0.0.0 \
+  --url http://kong:8000 \
+  --anon-key <your-anon-key> \
+  --service-key <your-service-key> \
+  --jwt-secret <your-jwt-secret> \
+  --db-url postgresql://postgres:password@db:5432/postgres
+```
+
+HTTP mode requires `--jwt-secret`. All `/mcp` requests must include a valid Supabase JWT in the `Authorization: Bearer <token>` header.
+
+The server communicates via stdio (default) or HTTP (Streamable HTTP Transport) and is designed to be invoked by an MCP client application (e.g., an IDE extension like Cursor). The client will connect to the server's stdio stream or HTTP endpoint to list and call the available tools.
+
+## Client Configuration Examples
+
+Below are examples of how to configure popular MCP clients to use this self-hosted server. 
+
+**Important:** 
+*   Replace placeholders like `<your-supabase-url>`, `<your-anon-key>`, `<your-db-url>`, `<path-to-dist/index.js>` etc., with your actual values.
+*   Ensure the path to the compiled server file (`dist/index.js`) is correct for your system.
+*   Be cautious about storing sensitive keys directly in configuration files, especially if committed to version control. Consider using environment variables or more secure methods where supported by the client.
+
+### Cursor
+
+1.  Create or open the file `.cursor/mcp.json` in your project root.
+2.  Add the following configuration:
+
+    ```json
+    {
+      "mcpServers": {
+        "selfhosted-supabase": { 
+          "command": "bun",
+          "args": [
+            "run",
+            "<path-to-dist/index.js>", // e.g., "/home/user/selfhosted-supabase-mcp/dist/index.js"
+            "--url",
+            "<your-supabase-url>", // e.g., "http://localhost:8000"
+            "--anon-key",
+            "<your-anon-key>",
+            // Optional - Add these if needed by the tools you use
+            "--service-key",
+            "<your-service-key>",
+            "--db-url",
+            "<your-db-url>", // e.g., "postgresql://postgres:password@host:port/postgres"
+            "--jwt-secret",
+            "<your-jwt-secret>",
+            // Optional - Whitelist specific tools
+            "--tools-config",
+            "<path-to-your-mcp-tools.json>" // e.g., "./mcp-tools.json"
+          ]
+        }
+      }
+    }
+    ```
+
+### Visual Studio Code (Copilot)
+
+VS Code Copilot allows using environment variables populated via prompted inputs, which is more secure for keys.
+
+1.  Create or open the file `.vscode/mcp.json` in your project root.
+2.  Add the following configuration:
+
+    ```json
+    {
+      "inputs": [
+        { "type": "promptString", "id": "sh-supabase-url", "description": "Self-Hosted Supabase URL", "default": "http://localhost:8000" },
+        { "type": "promptString", "id": "sh-supabase-anon-key", "description": "Self-Hosted Supabase Anon Key", "password": true },
+        { "type": "promptString", "id": "sh-supabase-service-key", "description": "Self-Hosted Supabase Service Key (Optional)", "password": true, "required": false },
+        { "type": "promptString", "id": "sh-supabase-db-url", "description": "Self-Hosted Supabase DB URL (Optional)", "password": true, "required": false },
+        { "type": "promptString", "id": "sh-supabase-jwt-secret", "description": "Self-Hosted Supabase JWT Secret (Optional)", "password": true, "required": false },
+        { "type": "promptString", "id": "sh-supabase-server-path", "description": "Path to self-hosted-supabase-mcp/dist/index.js" },
+        { "type": "promptString", "id": "sh-supabase-tools-config", "description": "Path to tools config JSON (Optional, e.g., ./mcp-tools.json)", "required": false }
+      ],
+      "servers": {
+        "selfhosted-supabase": {
+          "command": "bun",
+          "args": [
+            "run",
+            "${input:sh-supabase-server-path}",
+            "--tools-config", "${input:sh-supabase-tools-config}"
+           ],
+          "env": {
+            "SUPABASE_URL": "${input:sh-supabase-url}",
+            "SUPABASE_ANON_KEY": "${input:sh-supabase-anon-key}",
+            "SUPABASE_SERVICE_ROLE_KEY": "${input:sh-supabase-service-key}",
+            "DATABASE_URL": "${input:sh-supabase-db-url}",
+            "SUPABASE_AUTH_JWT_SECRET": "${input:sh-supabase-jwt-secret}"
+          }
+        }
+      }
+    }
+    ```
+3.  When you use Copilot Chat in Agent mode (@workspace), it should detect the server. You will be prompted to enter the details (URL, keys, path) when the server is first invoked.
+
+### Other Clients (Windsurf, Cline, Claude)
+
+Adapt the configuration structure shown for Cursor or the official Supabase documentation, replacing the `command` and `args` with the `bun run` command and the arguments for this server, similar to the Cursor example:
+
+```json
+{
+  "mcpServers": {
+    "selfhosted-supabase": { 
+      "command": "bun",
+      "args": [
+        "run",
+        "<path-to-dist/index.js>", 
+        "--url", "<your-supabase-url>", 
+        "--anon-key", "<your-anon-key>", 
+        "--service-key", "<your-service-key>", 
+        "--db-url", "<your-db-url>", 
+        "--jwt-secret", "<your-jwt-secret>",
+        "--tools-config", "<path-to-your-mcp-tools.json>"
+      ]
+    }
+  }
+}
+```
+Consult the specific documentation for each client on where to place the `mcp.json` or equivalent configuration file.
+
+## Docker Integration with Self-Hosted Supabase
+
+This MCP server can be integrated directly into a self-hosted Supabase Docker Compose stack, making it available alongside other Supabase services via the Kong API gateway.
+
+### Architecture Overview
+
+When integrated with Docker:
+- The MCP server runs in HTTP transport mode (not stdio)
+- It's exposed through Kong at `/mcp/v1/*`
+- JWT authentication is handled by the MCP server itself
+- The server has direct access to the database and all Supabase keys
+
+### Setup Steps
+
+#### 1. Add the MCP Server as a Git Submodule
+
+From your Supabase Docker directory:
+
+```bash
+git submodule add https://github.com/HenkDz/selfhosted-supabase-mcp.git selfhosted-supabase-mcp
+```
+
+#### 2. Create the Dockerfile
+
+Create `volumes/mcp/Dockerfile`:
+
+```dockerfile
+# Dockerfile for selfhosted-supabase-mcp HTTP mode
+# Multi-stage build using Bun runtime for self-hosted Supabase
+
+FROM oven/bun:1.1-alpine AS builder
+
+WORKDIR /app

+
+#### 3. Add the MCP Service to docker-compose.yml
+
+Add this service definition to your `docker-compose.yml`:
+
+```yaml
+## MCP Server - Model Context Protocol for AI integrations
+## DISABLED BY DEFAULT - Add 'mcp' to COMPOSE_PROFILES to enable
+mcp:
+  container_name: ${COMPOSE_PROJECT_NAME:-supabase}-mcp
+  profiles:
+    - mcp
+  build:
+    context: .
+    dockerfile: ./volumes/mcp/Dockerfile
+  restart: unless-stopped
+  healthcheck:
+    test:
+      [
+        "CMD",
+        "wget",
+        "--no-verbose",
+        "--tries=1",
+        "--spider",
+        "http://localhost:3100/health"
+      ]
+    timeout: 5s
+    interval: 10s
+    retries: 3
+  depends_on:
+    db:
+      condition: service_healthy
+    rest:
+      condition: service_started
+  environment:
+    SUPABASE_URL: http://kong:8000
+    SUPABASE_ANON_KEY: ${ANON_KEY}
+    SUPABASE_SERVICE_ROLE_KEY: ${SERVICE_ROLE_KEY}
+    SUPABASE_AUTH_JWT_SECRET: ${JWT_SECRET}
+    DATABASE_URL: postgresql://postgres:${POSTGRES_PASSWORD}@${POSTGRES_HOST}:${POSTGRES_PORT}/${POSTGRES_DB}
+  command:
+    [
+      "bun",
+      "run",
+      "dist/index.js",
+      "--transport", "http",
+      "--port", "3100",
+      "--host", "0.0.0.0",
+      "--url", "http://kong:8000",
+      "--anon-key", "${ANON_KEY}",
+      "--service-key", "${SERVICE_ROLE_KEY}",
+      "--jwt-secret", "${JWT_SECRET}",
+      "--db-url", "postgresql://postgres:${POSTGRES_PASSWORD}@${POSTGRES_HOST}:${POSTGRES_PORT}/${POSTGRES_DB}"
+    ]
+```
+
+#### 4. Add Kong API Gateway Routes
+
+Add the MCP routes to `volumes/api/kong.yml` in the `services` section:
+
+```yaml
+## MCP Server routes - Model Context Protocol for AI integrations
+## Authentication is handled by the MCP server itself (JWT validation)
+- name: mcp-v1
+  _comment: 'MCP Server: /mcp/v1/* -> http://mcp:3100/*'
+  url: http://mcp:3100/
+  routes:
+    - name: mcp-v1-all
+      strip_path: true
+      paths:
+        - /mcp/v1/
+  plugins:
+    - name: cors
+      config:
+        origins:
+          - "$SITE_URL_PATTERN"
+          - "http://localhost:3000"
+          - "http://127.0.0.1:3000"
+        methods:
+          - GET
+          - POST
+          - DELETE
+          - OPTIONS
+        headers:
+          - Accept
+          - Authorization
+          - Content-Type
+          - X-Client-Info
+          - apikey
+          - Mcp-Session-Id
+        exposed_headers:
+          - Mcp-Session-Id
+        credentials: true
+        max_age: 3600
+```
+
+#### 5. Enable the MCP Service
+
+The MCP service uses Docker Compose profiles, so it's disabled by default. To enable it:
+
+**Option A: Set in `.env` file:**
+```bash
+COMPOSE_PROFILES=mcp
+```
+
+**Option B: Enable at runtime:**
+```bash
+docker compose --profile mcp up -d
+```
+
+### Accessing the MCP Server
+
+Once running, the MCP server is available at:
+- **Internal (from other containers):** `http://mcp:3100`
+- **External (via Kong):** `http://localhost:8000/mcp/v1/`
+
+### Authentication
+
+When running in HTTP mode, the MCP server validates JWTs using the configured `JWT_SECRET`. Clients must include a valid Supabase JWT in the `Authorization` header:
+
+```
+Authorization: Bearer <supabase-jwt>
+```
+
+The JWT's `role` claim determines access:
+- `service_role`: Full access to all tools (regular + privileged)
+- `authenticated`: Access to regular tools only
+- `anon`: No tool access
+
+### Health Check
+
+The MCP server exposes a health endpoint:
+```bash
+curl http://localhost:8000/mcp/v1/health
+```
+
+### Security Considerations
+
+When deploying via Docker:
+1. The MCP server runs as a non-root user (`mcp:mcp`)
+2. JWT authentication is enforced for all tool calls
+3. Privileged tools (like `execute_sql`) require `service_role` JWT
+4. CORS is configured via Kong - adjust origins for your deployment
+
+## Development

+# Notes for Minimal Selfhosted Supabase MCP Server
+
+This document summarizes the findings and decisions made while attempting to adapt the official Supabase cloud MCP server for self-hosted use. The goal is to build a new, minimal server from scratch using these notes.
+
+## Core Requirements
+
+-   **Target:** Self-hosted Supabase instances.
+-   **Scope:** Single project environment.
+-   **Runtime:** Bun (v1.3+) - migrated from Node.js for faster startup and built-in TypeScript support.
+-   **Authentication:** Supabase URL and Anon Key required. Service Role Key optional (but recommended for certain operations like auto-creating helper functions).
+-   **Configuration:** Server should accept URL/Keys via CLI arguments (e.g., using `commander`) or environment variables (`SUPABASE_URL`, `SUPABASE_ANON_KEY`, `SUPABASE_SERVICE_ROLE_KEY`). Also needs `DATABASE_URL` for direct DB fallback/transactions.
+
+## Client Implementation (`SelfhostedSupabaseClient`)
+
+-   **Primary Connection:** Use `@supabase/supabase-js` client initialized with user-provided URL and Anon Key.
+-   **Core SQL Execution:**
+    -   Prefer using a PostgreSQL RPC function (`public.execute_sql`) called via the Supabase JS client (`supabase.rpc(...)`). This leverages the existing connection pool and permissions.
+    -   The client should check if this function exists on initialization. If not found (error code `42883`), and if the `serviceRoleKey` is available, attempt to create the function using a temporary service role client or the direct DB connection.
+    -   **RPC Function SQL:**
+        ```sql
+        -- SQL to create the helper function
+        CREATE OR REPLACE FUNCTION public.execute_sql(query text, read_only boolean DEFAULT false)
+        RETURNS jsonb -- Using jsonb is generally preferred over json
+        LANGUAGE plpgsql
+        AS $$
+        DECLARE
+          result jsonb;
+        BEGIN
+          -- Note: SET TRANSACTION READ ONLY might not behave as expected within a function
+          -- depending on the outer transaction state. Handle read-only logic outside if needed.
+
+          -- Execute the dynamic query and aggregate results into a JSONB array
+          EXECUTE 'SELECT COALESCE(jsonb_agg(t), ''[]''::jsonb) FROM (' || query || ') t' INTO result;
+
+          RETURN result;
+        EXCEPTION
+          WHEN others THEN
+            -- Rethrow the error with context
+            RAISE EXCEPTION 'Error executing SQL: %', SQLERRM;
+        END;
+        $$;
+
+        -- Grant execution permission (run using service key or manually)
+        GRANT EXECUTE ON FUNCTION public.execute_sql(text, boolean) TO authenticated;
+        -- Optionally grant to anon if needed: GRANT EXECUTE ON FUNCTION public.execute_sql(text, boolean) TO anon;
+        ```
+-   **Fallback/Transactional SQL Execution:**
+    -   Implement a secondary method (`executeSqlWithPg`) using the `pg` library (Node-postgres).
+    -   This method requires the `DATABASE_URL` environment variable to be set for the direct connection string.
+    -   Initialize the `pg.Pool` lazily on the first call to this method.
+    -   Use this method as a fallback if the RPC call fails *after* initialization, or specifically for operations requiring transaction control (like `apply_migration`).
+-   **Client Initialization:** The factory function (`createSelfhostedSupabaseClient`) should be `async` and perform the RPC check/create logic during an `await client.initialize()` step before returning the client instance.
+-   **Type Safety:** Use specific types (`unknown`, `Record<string, unknown>`) instead of `any`. Leverage TypeScript type inference and define types for options and responses.
+
+## Supported Tools
+
+Based on analysis, the following tools are relevant for a self-hosted context:
+
+*   **Database Operations:**
+    *   `list_tables` (Uses `pg-meta` logic)
+    *   `list_extensions` (Uses `pg-meta` logic)
+    *   `list_migrations` (Queries `supabase_migrations.schema_migrations`)
+    *   `apply_migration` (Executes DDL + inserts into `supabase_migrations.schema_migrations`; ideally uses `executeSqlWithPg` for transaction)
+    *   `execute_sql` (Primary interface to `SelfhostedSupabaseClient.executeSql`)
+*   **Debugging:**
+    *   `get_logs` (Needs careful implementation; direct DB query of `pg_log` might be feasible but depends on setup. May need to be removed or simplified).
+    *   `get_database_connections` (Queries `pg_stat_activity`)
+    *   `get_database_stats` (Queries `pg_stat_*` views)
+*   **Development & Configuration:**
+    *   `get_project_url` (Returns configured URL)
+    *   `generate_typescript_types` (Relies on DB introspection, potentially wrap `supabase gen types` or use `pg-meta`)
+    *   `rebuild_hooks` (Interacts with `pg_net` if database webhooks are used)
+    *   `verify_jwt_secret` (Useful for Auth debugging)
+    *   ~~`get_anon_key`~~ (Removed - security risk: exposes sensitive keys via MCP)
+    *   ~~`get_service_key`~~ (Removed - security risk: exposes sensitive keys via MCP)
+*   **Edge Functions (If Enabled):**
+    *   `list_edge_functions`
+    *   `deploy_edge_function`
+
+## Removed Tools (Cloud-Specific)
+
+The following tools from the original cloud server are not applicable and should *not* be implemented:
+
+*   Project Management (`list_projects`, `create_project`, etc.)
+*   Branching (`create_branch`, `list_branches`, etc.)
+*   Cost Confirmation (`get_cost`, `confirm_cost`)
+
+## Server Entry Point (`selfhosted-stdio.ts`)
+
+-   Use `commander` for parsing CLI arguments (`--url`, `--anon-key`, etc.) and reading environment variables as fallbacks.
+-   Implement an `async main()` function.
+-   Call the `async createSelfhostedSupabaseClient` factory.
+-   Create tool instances by passing the initialized `selfhostedClient` to tool generator functions (e.g., `getDatabaseOperationTools({ selfhostedClient, readOnly })`).
+-   Initialize the MCP SDK (`@modelcontextprotocol/sdk`) with `stdio: true` and the combined dictionary of tool instances.
+-   Include robust error handling for client initialization and server startup.
+
+## Dependencies
+
+-   **Runtime:** Bun v1.3+ (replaces Node.js)
+-   **Core:** `@supabase/supabase-js`, `pg`, `zod` (v4.x), `commander`, `@modelcontextprotocol/sdk`.
+-   **Dev:** `@types/bun`, `@types/node`, `@types/pg`, `typescript`
+
+## Zod v4 Compatibility Notes
+
+Updated for Zod v4 breaking changes:
+-   `z.ZodError.errors` → `z.ZodError.issues`
+-   `z.record(z.unknown())` → `z.record(z.string(), z.unknown())`
+-   `z.string().optional()` → `z.optional(z.string())` for better type inference
+-   `z.coerce` API changes handled with `z.union().transform()`
+
+## Useful Logic to Re-use
+
+-   SQL generation logic from `packages/pg-meta` (e.g., `listTablesSql`, `listExtensionsSql`).
+-   The `injectableTool` utility from `tools/util.ts` for structuring tool definitions with Zod schemas.
+
+## Reason for Restart
+
+Adapting the official cloud MCP server proved overly complex due to:
+-   Deep integration with the multi-project/Management API paradigm.
+-   Need for extensive refactoring of options and logic paths.
+-   Inherited build complexities and dependencies not strictly necessary for a minimal self-hosted server.
+
+Building from scratch allows for a cleaner, more focused implementation tailored specifically to the self-hosted use case.
