AI agents use memvid_correct to create or update resources in Memvid — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Memvid environment.
This tool modifies data by amending frame content within a memory file. However, it is explicitly designed to be reversible by preserving original content for audit purposes (creating a correction record rather than overwriting). This makes it Write rather than Destructive.
From the tool's definition The tool description states it "Correct/amend content of a frame" and explicitly mentions it "Creates a correction record preserving the original content".

Correct/amend content of a frame. Creates a correction record preserving the original content for audit purposes. Use this instead of update when you want to maintain history. Args: file: Path to the .mv2 memory file frame_id: Frame ID to correct content: Corrected content Returns: JSON with correction record ID. It is categorised as a Write tool in the Memvid MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Memvid MCP server in PolicyLayer and add a rule for memvid_correct: 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_correct is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the memvid_correct 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_correct. 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_correct 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.
