Search all visible user-owned XMemo long-term memory by semantic similarity, including memories written by other connected agents. Use before answering questions about prior decisions, preferences, or project context.
AI agents call memory_search to retrieve information from Openclaw Memory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
memory_search is a retrieval tool that queries existing data (long-term memory records) without side effects. No data is created, modified, deleted, or used to trigger external actions. The blast radius of misuse is minimal—an agent could retrieve sensitive historical context, but cannot alter it or commit irreversible actions. This is a classic Read category tool.
From the tool's definition Tool description states it 'search[es]' and retrieves 'memories' by 'semantic similarity' without modifying, deleting, or executing operations. It explicitly performs a query operation to 'use before answering questions', indicating retrieval-only semantics.
Attacks that exploit this kind of access
Search all visible user-owned XMemo long-term memory by semantic similarity, including memories written by other connected agents. Use before answering questions about prior decisions, preferences, or project context. It is categorised as a Read tool in the Openclaw Memory MCP Server, which means it retrieves data without modifying state.
Register the Openclaw Memory 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 Openclaw Memory. 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 Openclaw Memory MCP server (@xmemo/openclaw-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
memory_search is one line of Openclaw Memory's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
