Search the knowledge base for relevant content.
AI agents call search_memory to retrieve information from Personal RAG 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 data from a personal knowledge base using semantic search. It performs a read-only operation analogous to a database query or search, returning matching content without creating, modifying, or deleting any data.
From the tool's definition Tool description states 'Search the knowledge base for relevant content' — a query operation with no modifications or side effects.
Attacks that exploit this kind of access
Search the knowledge base for relevant content. It is categorised as a Read tool in the Personal RAG MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Personal RAG MCP Server MCP server in PolicyLayer and add a rule for search_memory: 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 Personal RAG MCP Server. Nothing to install.
search_memory 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 search_memory 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 search_memory. 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.
search_memory is provided by the Personal RAG MCP Server MCP server (timerickson/personal-rag-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
