AI agents call memvid_version to retrieve information from Memvid without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool simply returns version information about the memvid system. It performs a read-only retrieval operation with no side effects, no code execution, no data modification, and no destructive capabilities. The minimal blast radius and non-sensitive nature of version information justifies a 'low' severity rating. High confidence due to clear, unambiguous intent and behavior.
From the tool's definition Tool name 'memvid_version' and description 'Print memvid version information' indicate a query operation that retrieves and displays version metadata without modifying, executing code, or affecting system state.

Register the Memvid MCP server in PolicyLayer and add a rule for memvid_version: 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 Memvid. Nothing to install.
memvid_version 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 memvid_version 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 memvid_version. 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.
memvid_version is provided by the Memvid MCP server (tapiocapioca/memvid-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
