AI agents call knowledge_search to retrieve information from Get笔记 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and searches data from a knowledge base without creating, modifying, or deleting information. It is purely a read operation that queries existing data and returns results, fitting the 'Read' category for data retrieval with no side effects.
From the tool's definition Tool performs 'AI增强搜索' (AI-enhanced search) and returns '深度处理的答案' (deeply processed answers) from a knowledge base. The description indicates retrieval and querying capabilities with no modification, deletion, or execution of external code.

Register the Get笔记 MCP Server MCP server in PolicyLayer and add a rule for knowledge_search: 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 Get笔记 MCP Server. Nothing to install.
knowledge_search 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 knowledge_search 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 knowledge_search. 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.
knowledge_search is provided by the Get笔记 MCP Server MCP server (pancrepal-xiaoyibao/get_biji_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
