Get overall database statistics and metadata
AI agents call get_database_stats to retrieve information from PostgreSQL MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves database metadata and statistics with no side effects, modification, execution, or deletion capabilities. It fits the Read category as a data retrieval operation. The read-only nature of the entire server and the passive information-gathering purpose indicate low severity and high confidence.
From the tool's definition Tool name 'get_database_stats' and description 'Get overall database statistics and metadata' indicate retrieval of read-only information.
Attacks that exploit this kind of access
Get overall database statistics and metadata. It is categorised as a Read tool in the PostgreSQL MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PostgreSQL MCP Server MCP server in PolicyLayer and add a rule for get_database_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 PostgreSQL MCP Server. Nothing to install.
get_database_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_database_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_database_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_database_stats is provided by the PostgreSQL MCP Server MCP server (jplwunder/postgres-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
