AI agents call list_jobs to retrieve information from Pgmcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list' operation is a non-destructive, read-only query that retrieves and returns information about jobs without side effects. Even if jobs could be sensitive, listing does not alter state. Low severity because exposure permits information disclosure but not data modification or execution of arbitrary operations.
From the tool's definition Tool name 'list_jobs' indicates retrieval of job information without modification. The description is empty, but the verb 'list' is a standard retrieval operation. Context from sibling tools (create_job, get_job) suggests this queries existing jobs.
Attacks that exploit this kind of access
list_jobs. It is categorised as a Read tool in the Pgmcp MCP Server, which means it retrieves data without modifying state.
Register the Pg MCP server in PolicyLayer and add a rule for list_jobs: 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 Pgmcp. Nothing to install.
list_jobs 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 list_jobs 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 list_jobs. 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.
list_jobs is provided by the Pg MCP server (veloper/pgmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
