What signal_connect does on Godot Breakpoint
AI agents use signal_connect 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 signal_connect is rated Medium
Connecting signals is a reversible modification operation that changes the runtime behavior and relationships within a Godot project. While it alters state (the signal connection graph), it can be undone (via signal_disconnect) and does not irreversibly delete data or execute arbitrary external operations.
From the tool's definition Tool name 'signal_connect' and description 'Connect a source node' indicate establishing a connection between nodes in Godot, which modifies the signal/callback structure of the scene.
Attacks that exploit this kind of access
The rule that runs signal_connect 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 signal_connect, this is the rule to start with:
signal_connect 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 signal_connect call is checked against it from then on.
Questions about signal_connect
Connect a source 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 signal_connect: 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.
signal_connect 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 signal_connect 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 signal_connect. 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.
signal_connect 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.
