🎯 What Sets Us Apart

Feature	Description
Code Mode (V8 Isolate)	Massive Token Savings: Execute complex, multi-step operations inside a secure, true V8 isolate (`worker_threads`). Stop burning tokens on back-and-forth tool calls and reduce your AI overhead by up to 90%.
Deterministic Error Handling	No more cryptic database errors causing AI hallucinations. We intercept and translate raw SQL exceptions into clear, actionable advice so your agent knows exactly how to recover without guessing.
248 Token-Optimized Tools	The largest PostgreSQL toolset on the MCP registry. Every query uses zero-cost token estimation and smart dataset truncation, ensuring agents always see the big picture without blowing their context windows.
OAuth 2.1 + Granular Control	Real enterprise security. Authenticate via OAuth 2.1 and control exactly who can read, write, or administer your database with precision scopes mapped down to the specific tool layer.
Audit Trails & Semantic Diffing	Total accountability. Track exactly what your AI is doing with detailed JSON logs, automatically snapshot schemas before mutations, and confidently review semantic row-by-row diffs before restoring data.
23 Resources & 20 Prompts	Instant database meta-awareness. Agents automatically read real-time health, performance, and replication metrics, and can invoke built-in prompt workflows for query tuning and schema design.
Introspection & Migrations	Prevent costly mistakes. Let your AI simulate the cascade impact of schema changes, safely order foreign-key updates, and track migration history automatically.
8 Extension Ecosystems	Ready for advanced workloads. First-class API support for pgvector (AI search), PostGIS (geospatial), pg_cron, pgcrypto, and more—all strictly typed and validated out of the box.
Smart Tool Filtering	Give your agent exactly what it needs without overflowing IDE limits. Dynamically compile your server with any combination of our 22 distinct tool groups.
Enterprise Infrastructure	Built for production. Blazing fast (millions of ops/sec), protected against SQL injection, features high-performance connection pooling, and supports both Streamable HTTP and Legacy SSE protocols simultaneously.

Suggested Rule (Add to AGENTS.md, GEMINI.md, etc)

MCP TOKEN MANAGEMENT:

Token Visibility: When interacting with postgres-mcp, always monitor the _meta.tokenEstimate (or metrics.tokenEstimate in Code Mode) returned in tool responses.
Audit Resource: Use the postgres://audit resource to review session-level token consumption and identify high-cost operations.
Proactive Efficiency: If operations are consuming high token counts, prefer code mode and proactively use limit parameters.

🛠️ Tool Filtering

IMPORTANT

All tool groups includeCode Mode (pg_execute_code) by default. To exclude it, add -codemode to your filter: --tool-filter cron,pgcrypto,-codemode

⭐ Code Mode (--tool-filter codemode) is the recommended configuration — it exposes pg_execute_code, a secure, true V8 isolate sandbox providing access to all 248 tools' worth of capability with up to 90% token savings. See Tool Filtering for alternatives.

Requires admin OAuth scope — execution is logged for audit

📖 See Full Installation Guide →

What Can You Filter?

The --tool-filter argument accepts groups or tool names — mix and match freely:

Filter Pattern	Example	Description
Groups only	`core,jsonb,transactions`	Combine individual groups
Tool names	`pg_read_query,pg_explain`	Custom tool selection
Group + Tool	`core,+pg_stat_statements`	Extend a group
Group - Tool	`core,-pg_drop_table`	Remove specific tools

Tool Groups (22 Available)

Group	Tools	Description
`codemode`	1	Code Mode (sandboxed code execution) 🌟 Recommended
`core`	21	Read/write queries, tables, indexes, convenience/drop tools
`transactions`	9	BEGIN, COMMIT, ROLLBACK, savepoints, status
`jsonb`	21	JSONB manipulation, queries, and pretty-print
`text`	14	Full-text search, fuzzy matching
`performance`	25	EXPLAIN, query analysis, optimization, diagnostics, anomaly detection

🌐 HTTP/SSE Transport (Remote Access)

For remote access, web-based clients, or HTTP-compatible MCP hosts, use the HTTP transport:

node dist/cli.js \
  --transport http \
  --port 3000 \
  --postgres "postgres://user:pass@localhost:5432/db"

Docker:

docker run --rm -p 3000:3000 \
  -e POSTGRES_URL=postgres://user:pass@host:5432/db \
  writenotenow/postgres-mcp:latest \
  --transport http --port 3000

The server supports two MCP transport protocols simultaneously, enabling both modern and legacy clients to connect:

Streamable HTTP (Recommended)

Modern protocol (MCP 2025-03-26) — single endpoint, session-based:

Method	Endpoint	Purpose
`POST`	`/mcp`	JSON-RPC requests (initialize, tools/list, etc.)
`GET`	`/mcp`	SSE stream for server notifications
`DELETE`	`/mcp`	Session termination

Sessions are managed via the Mcp-Session-Id header.

Stateless Mode

For serverless/stateless deployments where sessions are not needed:

node dist/cli.js --transport http --port 3000 --stateless --postgres "postgres://..."

In stateless mode: GET /mcp returns 405, DELETE /mcp returns 204, /sse and /messages return 404. Each POST /mcp creates a fresh transport.

Legacy SSE (Backward Compatibility)

Legacy protocol (MCP 2024-11-05) — for clients like Python mcp.client.sse:

Method	Endpoint	Purpose
`GET`	`/sse`	Opens SSE stream, returns `/messages?sessionId=<id>` endpoint
`POST`	`/messages?sessionId=<id>`	Send JSON-RPC messages to the session

Utility Endpoints

Method	Endpoint	Purpose
`GET`	`/health`	Health check (bypasses rate limiting, always available for monitoring)

🔐 Authentication

postgres-mcp supports two authentication mechanisms for HTTP transport:

Simple Bearer Token (`--auth-token`)

Lightweight authentication for development or single-tenant deployments:

node dist/cli.js --transport http --port 3000 --auth-token my-secret --postgres "postgres://..."

# Or via environment variable
export MCP_AUTH_TOKEN=my-secret
node dist/cli.js --transport http --port 3000 --postgres "postgres://..."

Clients must include Authorization: Bearer my-secret on all requests. /health and / are exempt. Unauthenticated requests receive 401 with WWW-Authenticate: Bearer headers per RFC 6750.

OAuth 2.1 (Enterprise)

Full OAuth 2.1 with RFC 9728/8414 compliance for production multi-tenant deployments:

node dist/cli.js \
  --transport http \
  --port 3000 \
  --postgres "postgres://user:pass@localhost:5432/db" \
  --oauth-enabled \
  --oauth-issuer http://localhost:8080/realms/postgres-mcp \
  --oauth-audience postgres-mcp-client

Additional flags: --oauth-jwks-uri <url> (auto-discovered if omitted), --oauth-clock-tolerance <seconds> (default: 60).

OAuth Scopes

Access control is managed through OAuth scopes:

Scope	Access Level
`read`	Read-only queries (SELECT, EXPLAIN)
`write`	Read + write operations
`admin`	Full administrative access
`full`	Grants all access
`db:{name}`	Access to specific database
`schema:{name}`	Access to specific schema
`table:{schema}:{table}`	Access to specific table

RFC Compliance

This implementation follows:

RFC 9728 — OAuth 2.1 Protected Resource Metadata
RFC 8414 — OAuth 2.1 Authorization Server Metadata
RFC 7591 — OAuth 2.1 Dynamic Client Registration

The server exposes metadata at /.well-known/oauth-protected-resource.

Note for Keycloak users: Add an Audience mapper to your client (Client → Client scopes → dedicated scope → Add mapper → Audience) to include the correct aud claim in tokens.

NOTE

Per-tool scope enforcement: Scopes are enforced at the tool level — each tool group maps to a required scope (read, write, or admin). When OAuth is enabled, every tool invocation checks the calling token's scopes before execution. When OAuth is not configured, scope checks are skipped entirely.

WARNING

HTTP without authentication: When using --transport http without enabling OAuth or --auth-token, all clients have full unrestricted access. Always enable authentication for production HTTP deployments. See SECURITY.md for details.

Priority: When both --auth-token and --oauth-enabled are set, OAuth 2.1 takes precedence. If neither is configured, the server warns and runs without authentication.
