从项目记忆中回忆相关信息
AI agents call recall_memory_tool to retrieve information from Memory MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/queries stored memory entries based on keywords. It has no side effects — it only reads and returns existing Markdown memory files. Misuse risk is low since it only exposes stored project memory contents.
From the tool's definition recall_memory_tool — 'recall' indicates retrieval; description translates to 'recall relevant information from project memory'

Register the Memory MCP server in PolicyLayer and add a rule for recall_memory_tool: 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 Memory MCP. Nothing to install.
recall_memory_tool 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 recall_memory_tool 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 recall_memory_tool. 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.
recall_memory_tool is provided by the Memory MCP server (jerryzhongj/memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
