What setup_navigation_link does on Godot
AI agents use setup_navigation_link 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 |
|---|---|---|---|
name | string | — | Node name |
dimension | string | — | Navigation dimension (default: 2d) |
properties | object | — | Link properties (start_position, end_position, bidirectional, enabled, navigation_layers) |
parent_path | string | — | Parent node path (omit for scene root) |
Parameters from the server's own tool schema.
Why setup_navigation_link is rated Medium
This tool creates new scene nodes (NavigationLink2D/3D objects) which modifies the project state reversibly. It is a Write operation since it adds/creates game engine objects without deleting or executing arbitrary code. Severity is medium because misconfiguration could affect game navigation logic, but changes are not financial, destructive, or system-level execution.
From the tool's definition Tool name 'setup_navigation_link' and description 'Add a NavigationLink2D or NavigationLink3D' indicate creation of new navigation objects in a Godot scene.
Attacks that exploit this kind of access
The rule that runs setup_navigation_link 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 setup_navigation_link, this is the rule to start with:
setup_navigation_link 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every setup_navigation_link call is checked against it from then on.
Questions about setup_navigation_link
Add a NavigationLink2D or NavigationLink3D for connecting navigation regions. It is categorised as a Write tool in the Godot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
setup_navigation_link accepts 4 parameters: name, dimension, properties, parent_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 setup_navigation_link: 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.
setup_navigation_link is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the setup_navigation_link 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 setup_navigation_link. 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.
setup_navigation_link is provided by the Godot MCP server (@keeveeg/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
