What move_file does on Code MCP Server
AI agents use move_file to create or update resources in Code MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Code MCP Server environment.
Why move_file is rated Medium
Moving or renaming files is a Write operation: it modifies data/structure without permanently destroying it. The action is reversible (can move back or rename again). While it could cause operational issues if misused (e.g., moving critical files), it does not irreversibly delete data (which would be Destructive) nor execute arbitrary code (which would be Execute).
From the tool's definition Tool named 'move_file' with description 'Move or rename a file or directory' — this modifies file system state by relocating or renaming files, which is reversible through another move operation.
Attacks that exploit this kind of access
The rule that runs move_file safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Code MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For move_file, this is the rule to start with:
move_file stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Code MCP Server, apply this rule, and every move_file call is checked against it from then on.
Questions about move_file
Move or rename a file or directory. It is categorised as a Write tool in the Code MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Code MCP Server 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 Code MCP Server. 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 Code MCP Server MCP server (agentics-ai/code-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
