Connect JustLog to Claude

JustLog works as an MCP server with both Claude on the web and Claude Code. Pick your setup below.

Both methods require a JustLog API key. Create one here first.

Claude Web (claude.ai)

1. Create an API Key

Go to the API Keys page, give your key a name, and click Create. Copy the key — you'll need it in the next step.

2. Add the MCP Server

  1. Go to claude.ai
  2. Open Settings (click your name in the bottom-left)
  3. Click Integrations, then Add more
  4. Choose Add custom MCP server
  5. Fill in:
    • Name: JustLog
    • URL:
  6. For Authentication, select API Key (Header)
  7. Enter your API key from step 1
  8. Click Add

3. Start Logging

Start a new conversation and JustLog tools will be available automatically.

Claude Code (CLI)

1. Create an API Key

Go to the API Keys page, give your key a name, and click Create. Copy the key.

2. Add to Your MCP Config

Add the following to your Claude Code MCP settings file (~/.claude/claude_mcp_config.json):

{
  "mcpServers": {
    "justlog": {
      "type": "url",
      "url": "https://k24xsd279c.execute-api.us-east-1.amazonaws.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Replace YOUR_API_KEY with the key from step 1.

3. Start Logging

Launch Claude Code and JustLog tools will be available. Try things like:

  • "I had 2 eggs and toast for breakfast"
  • "I went for a 30 minute run"
  • "I weigh 185 lbs"
  • "What have I eaten today?"
  • "How many calories this week?"
