WHAT IT DOES

What edit_script does on Godot

AI agents use edit_script to create or update resources in Godot, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot environment.

Parameter	Type	Required	Description
`path`	string	Yes	Script file path (e.g. 'res://scripts/player.gd')
`new_text`	string	Yes	Replacement text
`old_text`	string	Yes	Exact text to find and replace

Parameters from the server's own tool schema.

RISK

Why edit_script is rated Medium

This tool modifies an existing source code file by replacing content within it. It is a write operation (file modification), but since it replaces rather than deletes the file entirely, it is reversible in principle (e.g., via version control). However, the blast radius is high because modifying GDScript files can alter game logic, introduce bugs, or create security vulnerabilities in the Godot project.

RECOMMENDED RULE

The rule that runs edit_script safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For edit_script, this is the rule to start with:

edit_script Rate-limited

edit_script 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.

    "edit_script": {
      "limits": [
        {
          "counter": "edit_script_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every edit_script call is checked against it from then on.
