What PostgreSQL_vacuum_analyze_table does on Postgres
AI agents invoke PostgreSQL_vacuum_analyze_table to trigger actions in Postgres. 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.
Why PostgreSQL_vacuum_analyze_table is rated High
VACUUM ANALYZE executes a database maintenance operation that reclaims storage and rebuilds query planner statistics. It is not a simple read, nor does it irreversibly delete user data (VACUUM reclaims dead tuples but does not drop tables or user data). It triggers an external database operation whose effects depend on the target table argument, placing it in the Execute category.

Attacks that exploit this kind of access
The rule that runs PostgreSQL_vacuum_analyze_table 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 PostgreSQL_vacuum_analyze_table, this is the rule to start with:
PostgreSQL_vacuum_analyze_table 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Postgres, apply this rule, and every PostgreSQL_vacuum_analyze_table call is checked against it from then on.
Questions about PostgreSQL_vacuum_analyze_table
Run VACUUM ANALYZE on a specific table to reclaim space and update statistics. It is categorised as a Execute tool in the Postgres MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Postgres MCP server in PolicyLayer and add a rule for PostgreSQL_vacuum_analyze_table: 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.
PostgreSQL_vacuum_analyze_table is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the PostgreSQL_vacuum_analyze_table 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 PostgreSQL_vacuum_analyze_table. 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.
PostgreSQL_vacuum_analyze_table 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.
