PGMCP
MCP server that converts natural language questions into SQL queries against any PostgreSQL database, returning results in table, JSON, or CSV format with streaming support for large result sets.
Best When
You want a safe, read-only natural language interface to an existing Postgres database and are using a MCP-compatible client like Claude Desktop or Cursor.
Avoid When
You need write access, multi-database federation, or are working with databases other than PostgreSQL.
Use Cases
- • Ask plain-English questions against a production Postgres database without writing SQL
- • Export database data to CSV/JSON via natural language commands
- • Schema discovery and exploration through conversational queries
- • Business analytics queries from non-technical users via AI assistants
- • Read-only database auditing and reporting workflows
Not For
- • Write operations — enforces read-only access by design
- • Non-PostgreSQL databases
- • Environments where connecting an AI to production DB credentials is not acceptable
