Chenji Affect

Chenji Affect MCP Server

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

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

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

Notes

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