Diligence — Self-Hosted Fitness Rewards with AI Agent Support

Points-based fitness accountability app. Log workouts and food, earn points, unlock rewards. Connect any AI agent via MCP for logging, coaching, and meal planning. Self-hosted, open source, zero cloud dependencies.

Built by DiligenceWorks.

Quick Start

Prerequisites

• Docker Desktop (Windows, macOS, or Linux)
• That's it. No Python, Node.js, or database install needed.

Install

macOS / Linux:

git clone https://github.com/diligenceworks/diligence
cd diligence
./setup.sh
docker compose up -d

Windows (PowerShell):

git clone https://github.com/diligenceworks/diligence
cd diligence
powershell -ExecutionPolicy Bypass -File setup.ps1
docker compose up -d

Windows (no script — manual):

git clone https://github.com/diligenceworks/diligence
cd diligence
copy .env.example .env
# Edit .env and set SECRET_KEY to any random string (e.g. mash the keyboard)
docker compose up -d

Open http://localhost and create your account. First user gets admin.

Verify

docker compose ps

You should see 4 containers, all healthy: frontend, backend, mcp-connector, fitness-db.

Features

• Points economy — earn from workouts, food logging, step goals. Daily gate locks rewards until you earn enough. Weekly reset.
• Science-based onboarding — PAR-Q+ safety screening, TTM stages of change, BREQ-2 motivation profiling.
• AI agent integration — 14 MCP tools for logging, coaching, meal planning, and device configuration.
• Meal plans — AI-generated plans with compliance tracking and points integration.
• Activity sync — Strava, Polar (OAuth 2.0). Garmin, Fitbit, Withings, WHOOP, Oura configurable in-app.
• Food search — Open Food Facts (4M+ products) + USDA FoodData Central (400K+ research-grade).
• Program tracking — 90-day structured programs (StrongLifts, Darebee, etc.) with day-by-day progression.
• Configurable rewards — you define what's worth earning. Gaming time, screen time, treats — your rules.

Connecting an AI Agent

Point your agent's MCP config at:

Environment	URL
Local (development)	http://localhost:3001/sse
Behind reverse proxy	https://your-domain/mcp

Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible agent.

Copy the contents of AGENT_GUIDE.md into your agent's system instructions for motivation-aware coaching.

Claude Desktop example

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "diligence": {
      "url": "http://localhost:3001/sse"
    }
  }
}

Then paste the contents of AGENT_GUIDE.md into your Claude Desktop project instructions.

Configuring Integrations

All integrations are configured through the app UI (Settings → Integrations) or through your AI agent. No .env file editing or container restarts needed.

Tell your agent: "I want to connect my Strava" — it will walk you through getting API credentials and store them encrypted.

Data Sovereignty

Diligence is self-hosted software. Your data never leaves your server. No cloud dependency, no vendor lock-in, no telemetry. MIT license — fork it, modify it, keep it forever.

Your fitness data — heart rate, body composition, food intake, GPS traces — is biometric data that deserves sovereignty.
