Plan directory move with recursive import updates for all contained files. Returns edit plans and file move suggestions without modifying the filesystem.
AI agents use planDirectoryMove to create or update resources in TypeScript Rename Helper — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your TypeScript Rename Helper environment.
This tool is classified as Write rather than Read because it not only retrieves information but generates structured edit plans intended to modify code. Although the tool itself doesn't execute these changes, it produces actionable modification directives.
From the tool's definition The tool 'planDirectoryMove' performs 'directory move with recursive import updates' and returns 'edit plans and file move suggestions'.
Attacks that exploit this kind of access
Plan directory move with recursive import updates for all contained files. Returns edit plans and file move suggestions without modifying the filesystem. It is categorised as a Write tool in the TypeScript Rename Helper MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the TypeScript Rename Helper MCP server in PolicyLayer and add a rule for planDirectoryMove: 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 TypeScript Rename Helper. Nothing to install.
planDirectoryMove 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 planDirectoryMove 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 planDirectoryMove. 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.
planDirectoryMove is provided by the TypeScript Rename Helper MCP server (t09tanaka/ts-rename-helper-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
