Chenji Affect tools (4)

write = sends, deletes, buys or posts
  • analyze_textFree

    L1 Affect Extraction: analyze text into an 8-dimensional emotion vector, emotion texture labels, causal intent classification, and a natural-language state description. text: input up to 2000 chars. lang: optional 'zh' or 'en'.

  • empathy_hintFree

    L3 Empathy Response Strategy: converts text into a deterministic response strategy (approach, tone temperature, pacing, focus points, avoid-list) for AI companions and conversational agents. Deterministic table lookup, no LLM, ~20ms; privacy-first. Not a medical or therapeutic tool.

  • generate_avatar_paramsFree

    L2 Avatar Driving Pipeline: one call returns blendshape/AU/curve animation parameters, lighting & material atmosphere package, adapter payload, plus the upstream L1 affect analysis. Requires a key tier that includes L2.

  • somatic_decodeFree

    L4 Somatic Emotion Decode: converts body-sensation text (e.g. tight chest, clenched fists) into structured emotion: primary affect, valence/arousal, emotion texture, causal intent, plus somatic anchor cues. Grounded in the somatic decoding discipline; wellness simulation only, not a diagnostic tool.

Chenji Affect MCP Server

<!-- mcp-name: io.github.zhiyu-dev/chenji-affect-mcp -->

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

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+.

pip install "mcp>=1.0,<2"

Get an API key:

  • Free BASIC plan (100 req/day, 3,000/month): subscribe on RapidAPI, or request a trial key at https://taichusjs.cn/trial.html.

Configure (Claude Desktop example)

{
  "mcpServers": {
    "chenji-affect": {
      "command": "python",
      "args": ["/absolute/path/to/server.py"],
      "env": {
        "CHENJI_API_KEY": "cj-your-key-here"
      }
    }
  }
}

Notes

  • L1 input is limited to 2000 characters (every 200 chars = 1 billing unit).
  • generateavatarparams requires a key tier that includes L2.
  • empathyhint and somaticdecode 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.
