Move or rename files and directories. Can move files between directories and rename them in a single operation. If the destination exists, the operation will fail.

AI agents use move_file to create or modify resources in Visual Memory Context. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call move_file repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Visual Memory Context.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Move or rename files and directories. Can move files between directories and rename them in a single operation. If the destination exists, the operation will fail. Works across different directories and can be used for simple renaming within the same directory. Both source and destination must be within allowed directories.. It is categorised as a Write tool in the Visual Memory Context MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Visual Memory Context MCP server in PolicyLayer and add a rule for move_file: 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 Visual Memory Context. Nothing to install.
move_file 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 move_file 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 move_file. 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.
move_file is provided by the Visual Memory Context MCP server (visual-memory-context-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
