Mcp Psycopg2
Connect your agent to PostgreSQL through psycopg2 so it can run schema-aware queries, migrations checks, and data debugging while you build your product.
Overview
io.github.daedalus/mcp-psycopg2 is a Build-phase MCP server that exposes psycopg2 PostgreSQL database adapter capabilities to AI agents via stdio.
What is this MCP server?
- Stdio MCP server v0.1.0 exposing psycopg2 PostgreSQL adapter operations
- PyPI package mcp-psycopg2 for pip-based MCP client registration
- Targets solo SaaS and API builders on Postgres rather than ORM-only workflows
- Repository daedalus/mcp-psycopg2 with official MCP server schema metadata
- Agent-tooling fit for inspect-query-fix loops during feature development
- Published server version 0.1.0
- One PyPI package entry registryType pypi identifier mcp-psycopg2
- stdio transport in MCP server manifest
What problem does it solve?
Your agent cannot see real Postgres state, so it hallucinates table shapes and misdiagnoses query bugs.
Who is it for?
Solo builders shipping Postgres-backed SaaS or APIs who want the agent in the loop for schema checks and ad hoc queries in dev.
Skip if: Production-only DBAs forbidding agent SQL, teams on serverless edge databases without psycopg2, or users needing a visual admin UI instead of MCP tools.
What do I get? / Deliverables
After registration, the agent can use psycopg2-backed MCP tools against your database for grounded SQL and connection troubleshooting.
- Configured MCP server using mcp-psycopg2 over stdio
- Agent-accessible PostgreSQL operations mediated by psycopg2
- Faster schema-verified backend iteration in your repo
Recommended MCP Servers
Journey fit
PostgreSQL access sits squarely in the build phase when you are wiring persistence, auth tables, billing rows, and analytics stores into a shippable app. Backend is the canonical shelf because psycopg2 is the server-side adapter layer agents need when reasoning about SQL, connections, and data integrity—not frontend polish.
How it compares
Database adapter MCP integration, not Supabase dashboard automation or a migrations-only Claude skill.
Common Questions / FAQ
Who is mcp-psycopg2 for?
Developers building on PostgreSQL who use Claude Code, Cursor, or Codex and want MCP tools grounded in psycopg2 rather than guessed SQL.
When should I use mcp-psycopg2?
During backend build and integration when you need the agent to verify schemas, test queries, or debug connection errors against a real dev database.
How do I add mcp-psycopg2 to my agent?
pip install mcp-psycopg2, add the stdio server block to your MCP client config, and provide a safe dev DATABASE_URL with least-privilege credentials.
