State management - show current memory state. Shows active session, binding status, and processing queue. Args: file: Path to the .mv2 memory file show: Display current state Returns: Current memory state information
AI agents call memvid_state 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 only retrieves and displays state information about the memory system. It queries the current state of an active session, binding status, and processing queue without creating, modifying, deleting, or executing any operations. This is a pure read operation with no side effects.
From the tool's definition Tool description states 'show current memory state' and 'Shows active session, binding status, and processing queue.' The action verb is 'show,' and the return value is 'Current memory state information' with no modification or side effects.

State management - show current memory state. Shows active session, binding status, and processing queue. Args: file: Path to the .mv2 memory file show: Display current state Returns: Current memory state information. It is categorised as a Read tool in the Memvid MCP Server, which means it retrieves data without modifying state.
Register the Memvid MCP server in PolicyLayer and add a rule for memvid_state: 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_state 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_state 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_state. 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_state 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.
