Psyche Ai
Add configurable mood, MBTI-driven personality, empathy, and trait drift so companion or branded agents feel consistent across sessions.
Overview
psyche-ai is an MCP server for the Build phase that adds emotional intelligence—mood, personality, empathy, and trait drift—to AI agents.
What is this MCP server?
- Neurotransmitter-style mood engine with empathy-oriented responses
- MBTI baseline via PSYCHE_MBTI (e.g., ENFP, INTJ) for personality defaults
- Three PSYCHE_MODE settings: natural, work, and companion
- PSYCHE_LOCALE en or zh for bilingual companion experiences
- npm psyche-ai v9.2.2 stdio MCP package with PSYCHE_NAME personalization
- npm package psyche-ai at version 9.2.2
- Four documented env vars: PSYCHE_MBTI, PSYCHE_NAME, PSYCHE_MODE, PSYCHE_LOCALE
- PSYCHE_MODE enum: natural, work, companion per server metadata
Community signal: 9 GitHub stars.
What problem does it solve?
Generic agents sound sterile or inconsistent, breaking trust for companion apps and persona-heavy indie products.
Who is it for?
Builders crafting companion agents, coaching bots, or niche communities that need persistent personality knobs.
Skip if: Teams that want neutral, strictly factual coding assistants with zero persona or mental-health adjacent UX.
What do I get? / Deliverables
After MCP registration and env tuning, sessions gain a stable emotional baseline and mode-aware tone without hand-authoring every reply style.
- MCP-accessible mood and personality state for the agent
- Mode-specific interaction style (natural, work, companion)
Recommended MCP Servers
Journey fit
Emotional modeling is Build agent-tooling: you tune how the assistant behaves before Ship and Launch positioning hardens the persona. Agent-tooling captures MCP controls for neurotransmitter mood and modes—not growth analytics or production incident monitoring.
How it compares
Persona and mood MCP layer, not an on-chain marketplace or document converter.
