# particles_set_lifetime Set the particle lifetime in seconds (> 0) on a GPUParticles2D/3D in the edited scene (undoable). In-scene and undoable — not gated. Agent View of the PolicyLayer registry record for `particles_set_lifetime`. HTML page: https://policylayer.com/tools/godot-breakpoint-mcp/particles-set-lifetime ## Facts - Tool: `particles_set_lifetime` - Server: Godot Breakpoint (`jlivingston-Cipher/godot-breakpoint-mcp`) — https://policylayer.com/tools/godot-breakpoint-mcp.md - Homepage: https://github.com/jlivingston-Cipher/godot-breakpoint-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "particles_set_lifetime", "arguments": {} } } ``` ## Why particles_set_lifetime is rated Medium This tool modifies scene state by changing particle lifetime parameters. However, the modification is explicitly undoable and affects only visual/simulation properties within the Godot editor context—not data deletion, code execution, or destructive changes. The blast radius is limited to unintended visual effects changes that can be easily reverted. From the tool's own definition: "'Set the particle lifetime' with 'undoable' indicates reversible modification of a particle emitter property in an active Godot scene. The tool modifies GPUParticles2D/3D properties but explicitly states the action is 'undoable'." ## Use case AI agents use particles_set_lifetime 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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
