What PostgreSQL_vacuum_progress_monitoring does on Postgres
AI agents call PostgreSQL_vacuum_progress_monitoring 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 PostgreSQL_vacuum_progress_monitoring is rated Low
This is a diagnostic and observational tool that retrieves the state of active VACUUM operations in PostgreSQL. VACUUM is a maintenance operation that runs independently; this tool only observes and reports on its progress and performance metrics. It has no side effects, performs no modifications to the database, and cannot alter or delete data.
From the tool's definition The tool 'PostgreSQL_vacuum_progress_monitoring' is described as 'Monitor active vacuum operations and their performance impact.' The key verb is 'Monitor' which indicates observation and retrieval of status information about ongoing vacuum operations.
Attacks that exploit this kind of access
The rule that runs PostgreSQL_vacuum_progress_monitoring 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_progress_monitoring, this is the rule to start with:
PostgreSQL_vacuum_progress_monitoring 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 PostgreSQL_vacuum_progress_monitoring call is checked against it from then on.
Questions about PostgreSQL_vacuum_progress_monitoring
Monitor active vacuum operations and their performance impact. 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 PostgreSQL_vacuum_progress_monitoring: 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_progress_monitoring 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 PostgreSQL_vacuum_progress_monitoring 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_progress_monitoring. 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_progress_monitoring 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.
