Postgres Mcp
Run SQL, inspect schema, EXPLAIN plans, and health-check Postgres from your agent while you build or debug production data issues.
Overview
io.github.YawLabs/postgres-mcp is a MCP server for the Build phase that lets your agent query PostgreSQL, introspect schema, EXPLAIN plans, and run health checks.
What is this MCP server?
- Execute SQL queries against PostgreSQL from the agent
- Schema introspection for tables, columns, and relationships
- EXPLAIN support for query plan debugging
- Database health checks for operate-time triage
- @yawlabs/postgres-mcp version 0.6.6 with stdio transport
- Package version 0.6.6 published as @yawlabs/postgres-mcp
- stdio MCP transport in server manifest
- Four described capabilities: query, schema introspection, explain, health checks
What problem does it solve?
Debugging SQL and schema without the agent seeing the real database forces slow copy-paste loops and wrong assumptions.
Who is it for?
Solo builders shipping on Postgres who want agent-assisted query tuning and schema exploration with a configured connection string.
Skip if: Greenfield projects with no Postgres instance yet or teams that forbid any agent database access for compliance reasons.
What do I get? / Deliverables
You get live queries, schema context, explain output, and health signals inside the same session where you edit backend code.
- Agent-executed SQL and result sets for debugging
- Schema metadata the model can reference while coding
- EXPLAIN output and health check summaries for tuning or ops
