## Questions

### Is there an official PostgreSQL MCP server?

Ubiquitous agent data source whose MCP ecosystem remains community maintained. mcpheaven lists PostgreSQL so agents can find it by task and reach it through one MCP endpoint.

### What can an AI agent do with PostgreSQL?

Run policy-checked queries and inspect schemas without exposing raw credentials. Agents find it by describing the task, for example with the search_capabilities tool.

### How do I connect PostgreSQL to Claude, Codex or Cursor?

Add mcpheaven once as an MCP server (https://mcpheaven.com/mcp) with an API key, then ask your agent for the task. It calls get_capability with the slug "postgresql" for details.

### Is the PostgreSQL integration available?

The PostgreSQL integration is planned. Agents can already discover it through mcpheaven's search, and it will become callable once the integration ships.
