What navagent_configure does on Godot Breakpoint
AI agents use navagent_configure to create or update resources in Godot Breakpoint, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot Breakpoint environment.
Why navagent_configure is rated Medium
This tool creates a new scene node and modifies its configuration properties, which are Write operations. It is not Destructive because the operation is explicitly marked as undoable, meaning it can be reversed. It does not execute arbitrary code or trigger external operations, so it is not Execute.
From the tool's definition Tool description states it will 'Add a NavigationAgent3D under a parent (undoable) and set any of its steering/avoidance properties.' The key action is adding/creating a new node and modifying its properties.
Attacks that exploit this kind of access
The rule that runs navagent_configure safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot Breakpoint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For navagent_configure, this is the rule to start with:
navagent_configure 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 Breakpoint, apply this rule, and every navagent_configure call is checked against it from then on.

Add a NavigationAgent3D under a parent (undoable) and set any of its steering/avoidance properties. Returns the new node. It is categorised as a Write tool in the Godot Breakpoint MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Godot Breakpoint MCP server in PolicyLayer and add a rule for navagent_configure: 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 Breakpoint. Nothing to install.
navagent_configure 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 navagent_configure 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 navagent_configure. 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.
navagent_configure is provided by the Godot Breakpoint MCP server (jlivingston-Cipher/godot-breakpoint-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
