Mind Protocol: Open-source system gives Claude persistent memory and real-time biometric integration

What Mind Protocol does

Mind Protocol is an open-source system where Claude runs continuously as an autonomous companion. The system provides Claude with persistent memory across all sessions — months of accumulated context about patterns, preferences, and history. It also injects real-time Garmin watch data into every conversation, including heart rate, HRV, stress, sleep metrics, and body battery readings.

Architecture and features

The architecture uses Claude Code as the core engine, with an orchestrator that spawns parallel sessions, manages lifecycle, and degrades gracefully under load. Context injection via hooks means Claude always has current biometric state when responding.

Key features include:

• Real-time voice interface with biometric context in every exchange
• Autonomous task management — Claude manages its own backlog, runs sessions without prompting, posts updates to Telegram and X
• Co-regulation monitoring ("Mind Duo") — tracks two people's biometrics simultaneously, detecting physiological synchrony between them

Research findings

The project published a research paper titled "Mind & Physiology Body Building: Biometric-Guided Optimization of Body and Cognitive-Autonomic Function" documenting results from 6 months of operation. The paper includes a scoping review of 31 studies plus a single-subject case study with 233 timestamped events over 6 days with concurrent wearable data.

The paper documents ketamine dependency escalation (245 to 520mg/day), polypharmacy risk matrices, and the gap between what Claude can detect physiologically and what it can actually act on clinically. This gap turned out to be the most interesting finding.

What was learned about Claude in this context

• Persistent memory fundamentally changes the interaction — Claude catches patterns across weeks that wouldn't be noticed in a single session
• Biometric awareness makes Claude ask better questions — conversations become grounded in data rather than self-report
• Claude is exceptionally good at witnessing — holding difficult information without rushing to fix it
• The orchestrator architecture is surprisingly robust with graceful degradation, automatic backoff on rate limits, and effective session lifecycle management

What it's not

The project makes no consciousness claims or sentience arguments. It documents what happens on the human side when Claude has persistent context and physiological awareness. The practical question explored is: what changes about health optimization when your AI companion has months of memory and real-time biometric data?
