What memory_search_index does on CoWork OS
AI agents call memory_search_index to retrieve information from CoWork OS without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why memory_search_index is rated Low
This tool queries and retrieves data from a memory system without modifying, deleting, or executing operations. It returns an index of results rather than taking any action. No side effects are produced. This is a straightforward Read category operation with low risk, as misuse would only expose existing data without causing changes or external effects.
From the tool's definition Tool name: 'memory_search_index'; description explicitly states 'Search structured memory observations' and 'return a compact index first.' The verb 'search' and lack of any modification, deletion, or execution capability indicates read-only data retrieval.
Attacks that exploit this kind of access
The rule that runs memory_search_index safely
PolicyLayer is an MCP gateway: it sits between your AI agents and CoWork OS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For memory_search_index, this is the rule to start with:
memory_search_index is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect CoWork OS, apply this rule, and every memory_search_index call is checked against it from then on.
Questions about memory_search_index
Search structured memory observations and return a compact index first. Prefer this over broad memory detail reads for deep recall. It is categorised as a Read tool in the CoWork OS MCP Server, which means it retrieves data without modifying state.
Register the CoWork OS MCP server in PolicyLayer and add a rule for memory_search_index: 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 CoWork OS. Nothing to install.
memory_search_index 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_index 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_index. 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_index is provided by the CoWork OS MCP server (CoWork-OS/CoWork-OS). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
