WHAT IT DOES

What search_brain does on MyChatArchive MCP Server

AI agents call search_brain to retrieve information from MyChatArchive MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why search_brain is rated Low

This tool performs a read-only search operation across local conversation data. While the specific description is empty, the context from the server description and sibling tools strongly indicates this is a retrieval/query function with no side effects. The minimal severity reflects that misuse would only expose existing conversation data already accessible locally, with no destructive or operational impact.

From the tool's definition Tool name 'search_brain' and sibling tools ('search_recent', 'get_context', 'get_profile') are all query/retrieval operations.

search_brain Allowed

search_brain is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
