AI agents call get_object_details to retrieve information from Pgsql without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata and schema information about database objects (tables, indexes, functions, etc.) without executing queries against data, modifying structures, or performing any side effects. It is purely informational, similar to the sibling 'list_objects' and 'list_schemas' tools that query the database catalog.

Attacks that exploit this kind of access
Show detailed information about a database object. It is categorised as a Read tool in the Pgsql MCP Server, which means it retrieves data without modifying state.
Register the Pgsql MCP server in PolicyLayer and add a rule for get_object_details: 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 Pgsql. Nothing to install.
get_object_details 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_object_details 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_object_details. 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_object_details is provided by the Pgsql MCP server (surajmandalcell/pgsql-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
