@motion-probe/mcp

MCP server for motion-probe: lets coding agents (Claude Code, Cursor, …) record React Native animations from what the native view layer renders and verify them against specs — no screen recordings, a few lines of text per check.

{
  "mcpServers": {
    "motion-probe": { "command": "npx", "args": ["-y", "-p", "@motion-probe/mcp", "motion-probe-mcp"] }
  }
}

The app needs @motion-probe/react-native (if (__DEV__) installMotionProbe()).

| Tool | | |---|---| | motion_record | arm → command / trigger → settle → report (+ PASS/FAIL with a spec) | | motion_arm / motion_report | when another tool (Maestro, mobile MCP, …) performs the interaction | | motion_send | run a handler the app registered with onMotionProbeCommand | | motion_baseline | turn the last recording into a regression spec | | motion_spec_from_tokens | build a spec from design motion tokens | | motion_analyze | re-analyze a saved trace | | motion_status, motion_easings | connection state, easing names |

The server hosts the local daemon while it runs, so the app stays connected between tool calls. Environment: MOTION_PROBE_PORT (default 7357), MOTION_PROBE_HOST.
