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...

Part of the Filesystem MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents use move_file to create or modify resources in Filesystem. 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. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Filesystem.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the move_file tool do? +

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 Filesystem MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on move_file? +

Add a rule in your Intercept YAML policy under the tools section for move_file. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Filesystem MCP server.

What risk level is move_file? +

move_file is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit move_file? +

Yes. Add a rate_limit block to the move_file rule in your Intercept 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.

How do I block move_file completely? +

Set action: deny in the Intercept 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.

What MCP server provides move_file? +

move_file is provided by the Filesystem MCP server (@modelcontextprotocol/server-filesystem). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
