JIT-verify candidates and return valid memories.
AI agents call vrm_retrieve to retrieve information from Verified Repo Memory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
vrm_retrieve retrieves and validates stored memories with no side effects. It does not create, modify, or delete data—only fetches and verifies. This is a pure Read operation with minimal security risk; misuse would expose cached repository information rather than cause destructive or operational harm.
From the tool's definition Tool description states 'JIT-verify candidates and return valid memories' — this retrieves and verifies existing data without modifying or deleting it.
Attacks that exploit this kind of access
JIT-verify candidates and return valid memories. It is categorised as a Read tool in the Verified Repo Memory MCP Server, which means it retrieves data without modifying state.
Register the Verified Repo Memory MCP server in PolicyLayer and add a rule for vrm_retrieve: 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 Verified Repo Memory. Nothing to install.
vrm_retrieve 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 vrm_retrieve 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 vrm_retrieve. 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.
vrm_retrieve is provided by the Verified Repo Memory MCP server (cognitivemyriad/mcp-verified-repo-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
