search_memory
AI agents call search_memory to retrieve information from MemoryMesh without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs semantic search over indexed personal files to retrieve matching documents or information. It is a read-only query operation that retrieves data without modifying, deleting, or executing external operations. The local-first architecture and private search context further confirm this is a data retrieval tool.
From the tool's definition Tool name 'search_memory' indicates a retrieval operation. Server description emphasizes 'semantic search' and 'query your data' as core functions. Sibling tools like 'query_timeline', 'get_document', and 'get_entity' are all read operations.
Attacks that exploit this kind of access
search_memory. It is categorised as a Read tool in the MemoryMesh MCP Server, which means it retrieves data without modifying state.
Register the MemoryMesh 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 MemoryMesh. 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 MemoryMesh MCP server (kilhubprojects/memory-mesh). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
