What analyze_vacuum_efficiency does on Postgres
AI agents call analyze_vacuum_efficiency to retrieve information from Postgres without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why analyze_vacuum_efficiency is rated Low
This tool performs analysis and generates recommendations based on existing vacuum metrics. It retrieves performance data about PostgreSQL's VACUUM operation and provides strategic advice, but does not execute VACUUM commands, modify configurations, or alter data. The sibling tools (analyze_buffer_utilization, analyze_query_plans, etc.) all follow a pattern of read-only diagnostic analysis.
From the tool's definition Tool name 'analyze_vacuum_efficiency' and description 'Analyze vacuum efficiency and recommend vacuum strategies' indicate a diagnostic and advisory function that retrieves and analyzes data about vacuum operations without modifying database state.
Attacks that exploit this kind of access
The rule that runs analyze_vacuum_efficiency safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Postgres, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For analyze_vacuum_efficiency, this is the rule to start with:
analyze_vacuum_efficiency is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Postgres, apply this rule, and every analyze_vacuum_efficiency call is checked against it from then on.
Questions about analyze_vacuum_efficiency
Analyze vacuum efficiency and recommend vacuum strategies. It is categorised as a Read tool in the Postgres MCP Server, which means it retrieves data without modifying state.
Register the Postgres MCP server in PolicyLayer and add a rule for analyze_vacuum_efficiency: 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 Postgres. Nothing to install.
analyze_vacuum_efficiency is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the analyze_vacuum_efficiency 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.
Set action: deny in the PolicyLayer policy for analyze_vacuum_efficiency. 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.
analyze_vacuum_efficiency is provided by the Postgres MCP server (mukul975/postgres-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
