What runtime_emit_signal does on Godot Breakpoint
AI agents invoke runtime_emit_signal to trigger actions in Godot Breakpoint. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why runtime_emit_signal is rated High
Emitting a signal on a live Godot node triggers arbitrary runtime callbacks and side effects depending on what is connected to that signal. This is an Execute-category action (triggers external operations whose effects depend on arguments).
From the tool's definition 'Emit a signal from a live node. DESTRUCTIVE — gated by confirmation.'
Attacks that exploit this kind of access
The rule that runs runtime_emit_signal 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 runtime_emit_signal, this is the rule to start with:
runtime_emit_signal stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 runtime_emit_signal call is checked against it from then on.
Questions about runtime_emit_signal
Emit a signal from a live node. DESTRUCTIVE — gated by confirmation. It is categorised as a Execute tool in the Godot Breakpoint MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Godot Breakpoint MCP server in PolicyLayer and add a rule for runtime_emit_signal: 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.
runtime_emit_signal is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the runtime_emit_signal 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 runtime_emit_signal. 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.
runtime_emit_signal 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.
