AI agents call memory_search to retrieve information from Claude Session Continuity without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
memory_search performs full-text and semantic search across stored project context memories, returning only reference data without modification. The explicit 'Read-only' designation, lack of mutation operations, and requirement to use separate tools (memory_get) for content access confirm this is a data retrieval function.
From the tool's definition The tool description explicitly states 'Read-only' and describes searching and retrieving stored memories. It returns 'compact index entries' and requires separate memory_get calls to fetch full content. This is a pure retrieval operation with no side effects.
Attacks that exploit this kind of access
Search stored memories using FTS5 full-text search or semantic/embedding similarity. Default mode returns compact index entries (id, type, truncated content) to save tokens — set detail=true for full content. Supports filtering by type, project, tags, and minimum importance. Read-only. Use memory_get to fetch full content for specific IDs found in search results. Use memory_related to explore graph connections from a known memory. It is categorised as a Read tool in the Claude Session Continuity MCP Server, which means it retrieves data without modifying state.
Register the Claude Session Continuity MCP server in PolicyLayer and add a rule for memory_search: 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 Claude Session Continuity. Nothing to install.
memory_search 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 memory_search 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 memory_search. 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.
memory_search is provided by the Claude Session Continuity MCP server (leesgit/claude-session-continuity-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
