Traggo MCP

An MCP server for Traggo, a tag-based time tracking tool.

traggo-mcp is a standalone stdio MCP server that exposes focused tools for time tracking workflows. It talks to Traggo through the GraphQL endpoint.

AI Disclaimer

This repo has almost entirely been AI-generated for personal use. It may not follow the best practices beyond those imposed by Rust and clippy.

Configuration

Required environment variables:

• TRAGGO_URL: full GraphQL endpoint URL, for example https://traggo.example.com/graphql.
• TRAGGO_TOKEN: Traggo device token.

Optional environment variables:

• TRAGGO_TIMEOUT_SECONDS: HTTP request timeout in seconds. Defaults to 30.
• RUST_LOG: tracing filter. Logs are written to stderr so stdout remains available for MCP stdio.

Create a dedicated Traggo device token in the Traggo web UI Devices tab. A NoExpiry device named mcp is convenient for trusted local deployments. Copy the token immediately because Traggo does not show existing tokens later.

Tools

• list_time_spans, create_time_span, update_time_span, remove_time_span
• list_timers, stop_timer
• list_tags, create_tag, update_tag, remove_tag
• suggest_tag_values
• get_stats

The server validates RFC3339 timestamps, required strings, stats ranges, and pagination bounds before sending requests to Traggo.

Native MCP Configuration

{
  "mcpServers": {
    "traggo": {
      "command": "traggo-mcp",
      "env": {
        "TRAGGO_URL": "https://traggo.example.com/graphql",
        "TRAGGO_TOKEN": "..."
      }
    }
  }
}

Docker MCP Configuration

The -i flag is required so the stdio MCP server can read from stdin.

{
  "mcpServers": {
    "traggo": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "-e",
        "TRAGGO_URL=https://traggo.example.com/graphql",
        "-e",
        "TRAGGO_TOKEN=...",
        "ghcr.io/ilyabizyaev/traggo-mcp:main"
      ]
    }
  }
}
