set_keyframe · Godot MCP Unified MCP: Risk & Policy

WHAT IT DOES

What set_keyframe does on Godot MCP Unified

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

WHY IT NEEDS A POLICY

Why set_keyframe needs a policy

This tool modifies animation track data by setting keyframe values at specific times. This is a write operation because it creates or updates animation keyframe data, which is reversible (keyframes can be moved, deleted, or updated later). It does not execute code, delete irreversibly, or trigger financial transactions.

From the tool's definition Tool description explicitly states 'Set a keyframe value' - a modification operation on animation data. The word 'Set' indicates creating or modifying animation track keyframes, which is reversible state change rather than deletion or code execution.

Verdict

set_keyframe Rate-limited

set_keyframe 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.

FAQ

Questions about set_keyframe

What does the set_keyframe tool do? +

Set a keyframe value at a specific time in an animation track. It is categorised as a Write tool in the Godot MCP Unified MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set_keyframe? +

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

What risk level is set_keyframe? +

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

Can I rate-limit set_keyframe? +

Yes. Add a rate_limit block to the set_keyframe 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 set_keyframe completely? +

Set action: deny in the PolicyLayer policy for set_keyframe. 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 set_keyframe? +

set_keyframe is provided by the Godot MCP Unified MCP server (pierrealexandreguillemin-a11y/godot-mcp-unified). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
