deepsearch · Jina AI MCP Server MCP: Risk & Policy

WHAT IT DOES

What deepsearch does on Jina AI MCP Server

AI agents invoke deepsearch to trigger actions in Jina AI MCP Server. 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 deepsearch needs a policy

This tool actively combines multiple operations (searching, reading, and reasoning) to conduct comprehensive investigations. It is not a simple read/query operation — it orchestrates external actions (web searches, content retrieval) and applies reasoning logic, making it an Execute-category tool.

deepsearch Rate-limited

deepsearch 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.
