Chenji Affect MCP Server

Turn raw text into structured affect signals — an 8-dimensional emotion vector, emotion texture labels, causal intent, 3D avatar driving parameters, empathy response strategies, and somatic-sensation emotion decoding — inside any MCP-capable client (Claude Desktop, Cursor, Qoder, etc.).

Powered by the Chenji Affect API (taichusjs.cn).

Tools

ToolLevelDescription
analyze_textL1Text → 8-dim affect vector + emotion texture + intent + state description
generate_avatar_paramsL2Text → blendshape/AU/curve animation package + lighting/atmosphere package + upstream L1
empathy_hintL3Text → deterministic empathy response strategy (approach, tone, pacing, focus, avoid-list), ~20ms, no LLM
somatic_decodeL4Body-sensation text → structured emotion (primary affect, valence/arousal, texture, intent) + somatic anchors

Remote mode (no install)

Clients that support streamable-http MCP can connect directly, no local package needed:

{
  "mcpServers": {
    "chenji-affect": {
      "type": "streamable-http",
      "url": "https://taichusjs.cn/mcp",
      "headers": { "x-api-key": "cj-your-key-here" }
    }
  }
}

Install

Requires Python 3.10+.

Notes

  • L1 input is limited to 2000 characters (every 200 chars = 1 billing unit).
  • generate_avatar_params requires a key tier that includes L2.
  • empathy_hint and somatic_decode are billed as L1-family calls (trial tier applies).
  • Privacy: raw text is never persisted by the API; only key hashes and telemetry are retained.
  • Wellness and affect-state simulation only — not a medical or diagnostic tool.
