Documentation Overview

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.).

Tools

Tool	Level	Description
`analyze_text`	L1	Text → 8-dim affect vector + emotion texture + intent + state description
`generate_avatar_params`	L2	Text → blendshape/AU/curve animation package + lighting/atmosphere package + upstream L1
`empathy_hint`	L3	Text → deterministic empathy response strategy (approach, tone, pacing, focus, avoid-list), ~20ms, no LLM
`somatic_decode`	L4	Body-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:

config.json

{

  "mcpServers": {

    "chenji-affect": {

      "type": "streamable-http",

      "url": "https://taichusjs.cn/mcp",

      "headers": { "x-api-key": "cj-your-key-here" }

    }

  }

}

Install

Requires Python 3.10+.

Terminal

pip install "mcp>=1.0,<2"

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)

config.json

{

  "mcpServers": {

    "chenji-affect": {

      "command": "python",

      "args": ["/absolute/path/to/server.py"],

      "env": {

        "CHENJI_API_KEY": "cj-your-key-here"

      }

    }

  }

}

Environment variables:

Variable	Required	Description
`CHENJI_API_KEY`	Yes	Your Chenji API key
`CHENJI_API_BASE`	No	Defaults to `https://taichusjs.cn`

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.
