search_by_date
AI agents call search_by_date 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 retrieves or filters indexed documents/entities based on date criteria with no described side effects. It does not modify, delete, or execute external operations. The blast radius of misuse is low—an agent querying indexed data by date cannot cause harm beyond potential information disclosure from the local index, which is inherently limited to the user's own files.
From the tool's definition Tool name 'search_by_date' implies a read operation that queries indexed personal files by temporal range, consistent with the server's stated purpose of 'private semantic search' and sibling tools like 'query_timeline' and 'get_document'.
Attacks that exploit this kind of access
search_by_date. 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_by_date: 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_by_date 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_by_date 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_by_date. 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_by_date 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.
search_by_date is one line of MemoryMesh's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
