Tools & Capabilities Breakdown

MCP Bizhawk Tools (22)

bizhawk_ping

PURPOSE: Verify that the BizHawk Lua bridge is connected and responding to RPC over the TCP socket. USAGE: Call this once at start-of-session before issuing other tool calls; if it succeeds, every other tool will work. BEHAVIOR: No side effects — pure liveness probe. Times out after ~10 seconds with a clear error if BizHawk isn't running, isn't pointed at the right host:port, or hasn't loaded lua/bridge.lua via Tools → Lua Console. RETURNS: The literal string 'pong' on success.

bizhawk_get_info

PURPOSE: Get the loaded ROM's name and hash, current frame count, the list of available memory domains, the active default domain (the one used when 'domain' is omitted on read/write tool calls), and the bridge's capability map (which optional emu/client/savestate/joypad/memory methods this BizHawk build exposes). USAGE: Call after bizhawk_ping to learn what system is loaded and which optional features are available; before any memory tool call to confirm the active domain and avoid silent reads from the wrong address space; before pause / unpause / reset / screenshot / save_state to check the corresponding `capabilities.*` flag. BEHAVIOR: No side effects — pure read of emulator metadata. Returns 'unavailable' for fields the loaded core doesn't expose (rom_name when no ROM is loaded, framecount on cores without emu.framecount, etc.). RETURNS: Multi-line text with ROM, ROM hash, framecount, memory_domains list, active domain, and a list of any missing capabilities for this build.
