Fulcra Context

Setup

Option 1: MCP Server (Recommended)

Use Fulcra's hosted MCP server at https://mcp.fulcradynamics.com/mcp (Streamable HTTP transport, OAuth2 auth).

Your human needs a Fulcra account (free via the Context iOS app or Portal).

Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "fulcra_context": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.fulcradynamics.com/mcp"]
    }
  }
}

Or run locally via uvx:

{
  "mcpServers": {
    "fulcra_context": {
      "command": "uvx",
      "args": ["fulcra-context-mcp@latest"]
    }
  }
}

Also tested with: Goose, Windsurf, VS Code. Open source: github.com/fulcradynamics/fulcra-context-mcp

Option 2: Direct API Access

1. Your human creates a Fulcra account
2. They generate an access token via the Python client or Portal
3. Store the token: skills.entries.fulcra-context.apiKey in openclaw.json

Option 3: Python Client (Tested & Proven)

pip3 install fulcra-api

from fulcra_api.core import FulcraAPI

api = FulcraAPI()
api.authorize()  # Opens device flow — human visits URL and logs in

# Now you have access:
sleep = api.metric_samples(start, end, "SleepStage")
hr = api.metric_samples(start, end, "HeartRate")
events = api.calendar_events(start, end)
catalog = api.metrics_catalog()

Save the token for automation:

import json
token_data = {
    "access_token": api.fulcra_cached_access_token,
    "expiration": api.fulcra_cached_access_token_expiration.isoformat(),
    "user_id": api.get_fulcra_userid()
}
with open("~/.config/fulcra/token.json", "w") as f:
    json.dump(token_data, f)

Token expires in ~24h. Use the built-in token manager for automatic refresh (see below).

Token Lifecycle Management

The skill includes scripts/fulcra_auth.py which handles the full OAuth2 lifecycle — including refresh tokens so your human only authorizes once.

# First-time setup (interactive — human approves via browser)
python3 scripts/fulcra_auth.py authorize

# Refresh token before expiry (automatic, no human needed)
python3 scripts/fulcra_auth.py refresh

# Check token status
python3 scripts/fulcra_auth.py status

# Get current access token (auto-refreshes if needed, for piping)
export FULCRA_ACCESS_TOKEN=$(python3 scripts/fulcra_auth.py token)

How it works:

• authorize runs the Auth0 device flow and saves both the access token AND refresh token
• refresh uses the saved refresh token to get a new access token — no human interaction
• token prints the access token (auto-refreshing if expired) — perfect for cron jobs and scripts

Set up a cron job to keep the token fresh:

For OpenClaw agents, add a cron job that refreshes the token every 12 hours:

python3 /path/to/skills/fulcra-context/scripts/fulcra_auth.py refresh

Token data is stored at ~/.config/fulcra/token.json (permissions restricted to owner).

Quick Commands

Check sleep (last night)

# Get time series for sleep stages (last 24h)
curl -s "https://api.fulcradynamics.com/data/v0/time_series_grouped?metrics=SleepStage&start=$(date -u -v-24H +%Y-%m-%dT%H:%M:%SZ)&end=$(date -u +%Y-%m-%dT%H:%M:%SZ)&samprate=300" \
  -H "Authorization: Bearer $FULCRA_ACCESS_TOKEN"

Check heart rate (recent)

curl -s "https://api.fulcradynamics.com/data/v0/time_series_grouped?metrics=HeartRate&start=$(date -u -v-2H +%Y-%m-%dT%H:%M:%SZ)&end=$(date -u +%Y-%m-%dT%H:%M:%SZ)&samprate=60" \
  -H "Authorization: Bearer $FULCRA_ACCESS_TOKEN"

Check today's calendar

curl -s "https://api.fulcradynamics.com/data/v0/{fulcra_userid}/calendar_events?start=$(date -u +%Y-%m-%dT00:00:00Z)&end=$(date -u +%Y-%m-%dT23:59:59Z)" \
  -H "Authorization: Bearer $FULCRA_ACCESS_TOKEN"

Available metrics

curl -s "https://api.fulcradynamics.com/data/v0/metrics_catalog" \
  -H "Authorization: Bearer $FULCRA_ACCESS_TOKEN"

Key Metrics

Integration Patterns

Morning Briefing

Check sleep + calendar + weather → compose a briefing calibrated to energy level.

Stress-Aware Communication

Monitor HRV + heart rate → if elevated, keep messages brief and non-urgent.

Proactive Recovery

After intense workout or poor sleep → suggest lighter schedule, remind about hydration.

Travel Awareness

Location changes → adjust timezone handling, suggest local info, modify schedule expectations.

Demo Mode

For public demos (VC pitches, livestreams, conferences), enable demo mode to swap in synthetic calendar and location data while keeping real biometrics.

Activation

# Environment variable (recommended for persistent config)
export FULCRA_DEMO_MODE=true

# Or pass --demo flag to collect_briefing_data.py
python3 collect_briefing_data.py --demo

What changes in demo mode

Transparency

• Output JSON includes "demo_mode": true at the top level
• Calendar and location objects include "demo_mode": true
• When presenting to humans, include a subtle "📍 Demo mode" indicator

What's safe to share publicly

• ✅ Biometric trends, sleep quality, step counts, HRV — cleared for public
• ✅ Synthetic calendar and location (demo mode) — designed for public display
• ❌ NEVER share real location, real calendar events, or identifying data
