WHAT IT DOES

What pg_vacuum_analyze does on PostgreSQL MCP Server

AI agents invoke pg_vacuum_analyze to trigger actions in PostgreSQL MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why pg_vacuum_analyze is rated High

VACUUM and ANALYZE are server-side operations that execute maintenance tasks (reclaiming storage and updating query planner statistics). They are not simple reads, and while not destructive to user data, they trigger significant server-side execution with potential performance impact. This falls under Execute as it runs external database operations whose effects depend on the target objects.

From the tool's definition "Run VACUUM and ANALYZE together" — triggers database maintenance operations on the PostgreSQL server

RECOMMENDED RULE

The rule that runs pg_vacuum_analyze safely

PolicyLayer is an MCP gateway: it sits between your AI agents and PostgreSQL MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pg_vacuum_analyze, this is the rule to start with:

pg_vacuum_analyze Rate-limited

pg_vacuum_analyze stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

          "max": 10,

    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect PostgreSQL MCP Server, apply this rule, and every pg_vacuum_analyze call is checked against it from then on.

FAQ

Questions about pg_vacuum_analyze

What does the pg_vacuum_analyze tool do? +

Run VACUUM and ANALYZE together for optimal performance. Verbose output goes to PostgreSQL server logs. It is categorised as a Execute tool in the PostgreSQL MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on pg_vacuum_analyze? +

Register the PostgreSQL MCP Server MCP server in PolicyLayer and add a rule for pg_vacuum_analyze: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches PostgreSQL MCP Server. Nothing to install.

What risk level is pg_vacuum_analyze? +

pg_vacuum_analyze is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit pg_vacuum_analyze? +

Yes. Add a rate_limit block to the pg_vacuum_analyze rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block pg_vacuum_analyze completely? +

Set action: deny in the PolicyLayer policy for pg_vacuum_analyze. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides pg_vacuum_analyze? +

pg_vacuum_analyze is provided by the PostgreSQL MCP Server MCP server (@neverinfamous/postgres-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
