What inputmap_add_event does on Godot Breakpoint
AI agents use inputmap_add_event 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 inputmap_add_event is rated Medium
This tool modifies project configuration by appending input events to input actions, which is reversible (events can be removed). It does not execute external code, delete data, or cause financial impact. The blast radius is medium because misconfigured input mappings could degrade game usability or be exploited to create unintended input handlers, but changes are non-destructive and can be undone.
From the tool's definition Tool name 'inputmap_add_event' and description 'Append an input event to an existing project input action' indicate creation/addition of configuration data to the project's input mapping system.
Attacks that exploit this kind of access
The rule that runs inputmap_add_event 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 inputmap_add_event, this is the rule to start with:
inputmap_add_event 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 inputmap_add_event call is checked against it from then on.
Questions about inputmap_add_event
Append an input event to an existing project input action. 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 inputmap_add_event: 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.
inputmap_add_event 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 inputmap_add_event 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 inputmap_add_event. 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.
inputmap_add_event 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.
