Get statistics for a table: estimated row count (from pg_stat), live/dead tuples, last vacuum/analyze times, and total disk size.
AI agents call get_table_stats to retrieve information from Mcp Postgres Query without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries PostgreSQL's built-in statistics tables to return informational metrics. It performs no writes, deletes, or execution of arbitrary code—only retrieves pre-computed statistics that are already available to any database user. The blast radius of misuse is minimal; an attacker could only learn about table sizes and maintenance history, not access or modify actual data.
From the tool's definition The tool retrieves statistics ('Get statistics for a table') including row counts, tuple counts, maintenance timestamps, and disk size from PostgreSQL system catalogs (pg_stat). These are read-only queries with no modification of data or schema.
Attacks that exploit this kind of access
Get statistics for a table: estimated row count (from pg_stat), live/dead tuples, last vacuum/analyze times, and total disk size. It is categorised as a Read tool in the Mcp Postgres Query MCP Server, which means it retrieves data without modifying state.
Register the Mcp Postgres Query MCP server in PolicyLayer and add a rule for get_table_stats: 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 Mcp Postgres Query. Nothing to install.
get_table_stats 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 get_table_stats 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 get_table_stats. 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.
get_table_stats is provided by the Mcp Postgres Query MCP server (lordbasilaiassistant-sudo/mcp-postgres-query). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
