flutter3d_sim_mcp

An MCP server, part of flutter3d: a shooter level an agent can play blind — ai-00 in doc/tooling-plan.md. Open a level, step it forward with input, read positions and health back in words, capture a headless frame with no GPU, and hand over the run it made as a .f3drun any other tool in this repository can open.

Genre-aware on purpose, unlike flutter3d_editor_mcp/ flutter3d_model_mcp: it knows what a monster and a weapon are, because the question it answers — "what does the room look like from here, and is the player still alive" — has no genre-agnostic version.

Speaks MCP over a socket rather than literal stdio: flutter test itself rewrites everything a test writes to stdout with its own prefix, which a protocol tied to an exact line format does not survive.
