What list_joints does on Godot
AI agents call list_joints to retrieve information from Godot without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
joint_type | object | — | Filter by joint type |
scene_path | object | — | Filter to a specific scene |
Parameters from the server's own tool schema.
Why list_joints is rated Low
This tool queries and returns information about existing physics joints in the Godot Engine without creating, modifying, deleting, or executing any operations. It is a straightforward data retrieval function, fitting the 'Read' category for safe, passive information queries.
From the tool's definition Tool name 'list_joints' and description 'List physics joints' indicate a retrieval operation with no modification or execution of side effects.
Attacks that exploit this kind of access
The rule that runs list_joints 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 list_joints, this is the rule to start with:
list_joints is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every list_joints call is checked against it from then on.
Questions about list_joints
List physics joints. It is categorised as a Read tool in the Godot MCP Server, which means it retrieves data without modifying state.
list_joints accepts 2 parameters: joint_type, scene_path. The full parameter table on this page comes from the server's own tool schema.
Register the Godot MCP server in PolicyLayer and add a rule for list_joints: 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. Nothing to install.
list_joints is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_joints 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.
Set action: deny in the PolicyLayer policy for list_joints. 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.
list_joints is provided by the Godot MCP server (@yanhuifair/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
