create_job · Pg MCP: Risk & Policy

WHAT IT DOES

What create_job does on Pgmcp

AI agents invoke create_job to trigger actions in Pgmcp. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why create_job needs a policy

The name 'create_job' suggests triggering or scheduling an operation (e.g., a background job for crawling, embedding, or DB administration), which falls under Execute. Given sibling tools like 'embed_corpus', 'get_job', 'get_job_logs', it likely schedules a task that executes external or DB operations. Severity is high due to potential blast radius of arbitrary job execution.

From the tool's definition Tool name 'create_job' on a server that performs PostgreSQL administration, web crawling, and knowledge base management. Description is empty.

Verdict

create_job Rate-limited

create_job stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
