WHAT IT DOES

What pg_vector_performance does on PostgreSQL MCP Server

AI agents invoke pg_vector_performance 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_vector_performance is rated High

This tool executes analysis operations against the PostgreSQL database, which qualifies as Execute rather than Read because benchmarking and performance analysis involve triggering actual query execution and measurement rather than simple retrieval. The testVector parameter suggests active workload execution.

From the tool's definition Tool performs 'Analyze vector search performance and index effectiveness' with optional 'testVector for benchmarking'. Analysis operations typically require executing queries against the database to measure performance metrics.

RECOMMENDED RULE

The rule that runs pg_vector_performance 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_vector_performance, this is the rule to start with:

pg_vector_performance Rate-limited

pg_vector_performance 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.

          "window": "minute",
          "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_vector_performance call is checked against it from then on.

FAQ

Questions about pg_vector_performance

What does the pg_vector_performance tool do? +

Analyze vector search performance and index effectiveness. Provide testVector for benchmarking (recommended). 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_vector_performance? +

Register the PostgreSQL MCP Server MCP server in PolicyLayer and add a rule for pg_vector_performance: 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_vector_performance? +

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

Can I rate-limit pg_vector_performance? +

Yes. Add a rate_limit block to the pg_vector_performance 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_vector_performance completely? +

Set action: deny in the PolicyLayer policy for pg_vector_performance. 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_vector_performance? +

pg_vector_performance 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.
