Why remove_path_alias_by_tsmorph needs a policy

This tool modifies source files by rewriting import/export path aliases to relative paths. It creates reversible changes to file contents (code can be restored via version control), making it a Write operation. However, severity is high because it can affect many files across an entire codebase simultaneously, and incorrect rewrites could break module resolution throughout the project.

From the tool's definition Convert path-alias imports/exports — rewrites import/export statements across files in the codebase

POLICY

How to control remove_path_alias_by_tsmorph

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP ts-morph Refactoring Tools, and nothing reaches the server without passing your rules. This is the rule we recommend for remove_path_alias_by_tsmorph:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "remove_path_alias_by_tsmorph": {
      "limits": [
        {
          "counter": "remove_path_alias_by_tsmorph_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

remove_path_alias_by_tsmorph 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.
