Search memory for a pattern
AI agents call search_memory to retrieve information from MCP Debug 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 queries memory contents to find patterns, which is a classic Read operation. It has no side effects—it does not modify, delete, or execute code. While attached to a process for debugging purposes, the operation itself is observational.
From the tool's definition Tool name is 'search_memory' with description 'Search memory for a pattern'. The verb 'search' indicates a read-only query operation. The context (debugging tool) reinforces this as memory inspection without modification.
Attacks that exploit this kind of access
Search memory for a pattern. It is categorised as a Read tool in the MCP Debug Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Debug 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 MCP Debug 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 MCP Debug Server MCP server (nickzer0/mcp-debugserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
