Nefesh Human State Agent
Provides real-time human physiological state awareness for AI agents. Fuses biometric signals (heart rate, HRV, voice, facial expression, text sentiment) into a unified stress score (0-100) with behavioral adaptation prompts. Includes trigger memory for cross-session psychological context and adaptation effectiveness feedback.
AgentCard object. It is an agent card in spirit rather than in schema — useful for
discovery, but an A2A client cannot assume it will parse.
no-protocolVersion
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.
Get Human State get-human-state
Returns current stress state (0-100), suggested_action (maintain/simplify/de-escalate/pause), and adaptation_effectiveness showing whether your previous action reduced stress.
biometricsstressadaptationIngest Biometric Signals ingest-signals
Send biometric signals (heart rate, HRV, voice tone, expression, sentiment, 30+ fields) and receive unified state. Include subject_id for cross-session trigger memory.
biometricssignalsingestGet Trigger Memory get-trigger-memory
Retrieve psychological trigger profile - which conversation topics cause stress (active) and which have been resolved over time.
triggerspsychologymemoryGet Session History get-session-history
Timestamped state history with trend (rising/falling/stable). Useful for detecting stress patterns during conversations.

Every agent card here is available over the APIs.io API and to AI agents over MCP. A2A Agent Cards is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
