Pluggable MCP Server (in your game) - to allow AI Editor to test running game

[JeffGillin]

I think we all see the LLMs doing it all soon, crazy as it is.
So - we need a pluggable way to add MCP functionality for the LLM to be able to get in game data, and stuff.
Maybe a plugin?
App::build()
.add_plugins(DefaultPlugins)
.add_plugin(BevyMcpPlugin::default()) // Plug & play MCP server
.run();

1 List Entities - Return a structured list of all current ECS entities.
2 Query Components - Get component data for specified entities (e.g., position, health).
3 Modify Component Values - Update or mutate component fields on entities at runtime.
4 Spawn/Despawn Entities - Dynamically create or remove entities during runtime.
5 Control Game State - Start, pause, resume, or stop the game loop or systems.
6 Run Tests / Diagnostics - Trigger automated tests or diagnostic systems and report results.
7 Capture & Return Game Stats - Provide runtime metrics like FPS, memory usage, or entity counts.
8 Trigger Events or Commands - Inject custom events into the ECS event queue or command buffer.
9 Access Resource Data - Query and update global resources used by systems.
10 Log & Debug Output Access - Stream or retrieve runtime logs, warnings, and error messages.
11 Modify System Execution Order - Change the execution order or enable/disable systems dynamically.
12 Query Asset Information - Retrieve info about loaded assets (textures, models, sounds).
13 Hot Reload Scripts or Shaders - Reload Rust scripts, shaders, or config files at runtime.
14 Take and Return Screenshots - Capture current framebuffer or render output as image data.
15 Manage Input States - Query or simulate user input events (keyboard, mouse, gamepad).
16 Adjust Rendering Settings - Change graphics settings like resolution, quality, or effects.
17 Modify Physics Parameters - Change physics world settings or apply forces to entities.
18 Access Network State - Query network connection status or simulate network events.
19 Control Audio Playback - Play, pause, or adjust sounds/music during runtime.
20 Export Runtime Data - Save ECS or game state snapshots for debugging or replay.

Yes, I used ChatGPT to help me come up with this list - I'm admittedly not the smart one in this corners (see).
Just need to open up this real nice game engine for the big brained computers to take over.

well - this works from outside your game: https://crates.io/search?q=bevy_brp_mcp
