update_project_uids · Godot MCP: Risk & Policy

WHAT IT DOES

What update_project_uids does on Godot MCP

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

WHY IT NEEDS A POLICY

Why update_project_uids needs a policy

The tool modifies UIDs (unique identifiers) in Godot project resources by resaving them. This is a write operation because it changes project data, but it's reversible (UIDs can be regenerated or corrected in subsequent operations). It doesn't delete data irreversibly (Destructive), execute arbitrary code (Execute), or transfer funds (Financial).

From the tool's definition Tool description states 'Update UID references in a Godot project by resaving resources' — this modifies project data through resource resaving, which is a reversible write operation.

Verdict

update_project_uids Rate-limited

update_project_uids 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.

How do I enforce a policy on update_project_uids? +

Register the Godot MCP server in PolicyLayer and add a rule for update_project_uids: 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 Godot MCP. Nothing to install.

What risk level is update_project_uids? +

update_project_uids is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit update_project_uids? +

Yes. Add a rate_limit block to the update_project_uids 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.

How do I block update_project_uids completely? +

Set action: deny in the PolicyLayer policy for update_project_uids. 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.

What MCP server provides update_project_uids? +
