Active semantic search across L2 memories with time/category/tag filters and state-dependent boosting.
AI agents call search to retrieve information from Strata Memory MCP 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 data from L2 memory tier using semantic search with filtering options. It has no side effects—it only reads and returns matching memory records based on the provided search criteria. This is a typical read operation with no capability to alter state or trigger external actions.
From the tool's definition Tool performs 'Active semantic search across L2 memories' with filtering capabilities. The description uses search/query verbs ('search', 'filters') with no mention of modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
Active semantic search across L2 memories with time/category/tag filters and state-dependent boosting. It is categorised as a Read tool in the Strata Memory MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Strata Memory MCP Server MCP server in PolicyLayer and add a rule for 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 Strata Memory MCP Server. Nothing to install.
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 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 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.
search is provided by the Strata Memory MCP Server MCP server (sherryli-vc/strata-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
