WHAT IT DOES

What write_project_config does on Godot

AI agents use write_project_config 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
`key`	string	Yes	Config key to set
`value`	string	Yes	Config value to set
`section`	string	Yes	Section name to add or modify (e.g. "application", "rendering")

Parameters from the server's own tool schema.

RISK

Why write_project_config is rated Medium

This tool creates or modifies project configuration data reversibly. While the change persists, it is not irreversibly destructive (configs can be edited or reverted) and does not delete data. The severity is high because misconfiguration of project.godot could break the Godot project, disable features, or introduce security issues, but changes are technically reversible by overwriting the config again.

From the tool's definition write_project_config: 'Write a config value to project.godot.' The tool explicitly writes/modifies configuration data to the project's central configuration file.

RECOMMENDED RULE

The rule that runs write_project_config 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 write_project_config, this is the rule to start with:

write_project_config Rate-limited

write_project_config 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.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "write_project_config": {
      "limits": [
        {
          "counter": "write_project_config_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 write_project_config call is checked against it from then on.
