What PostgreSQL exposes to your agents

What can go wrong

Even read-only tools carry cost. An agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up bills.

How to control PostgreSQL

PolicyLayer is an MCP gateway — it sits between your AI agents and PostgreSQL, and nothing reaches the server without passing your rules. These are the rules we recommend:

Cap read operations
{
  "query": {
    "limits": [
      {
        "counter": "query_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

  1. Create a free account and register PostgreSQL — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about PostgreSQL

Is the PostgreSQL MCP server safe to use without restrictions? +

The PostgreSQL server is primarily read-only with 1 read tools. While it cannot modify data, an agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up costs. Rate limiting is still recommended.

How many tools does the PostgreSQL MCP server expose? +

1 tools across 1 categories: Read. 1 are read-only. 0 can modify, create, or delete data.

How do I enforce a policy on PostgreSQL? +

Register the PostgreSQL MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.
