TMetric Server

Minimal Model Context Protocol server for TMetric time tracking integration.

Features

• List TMetric projects
• Start/stop timers
• Check current timer status
• GitLab issue integration
• Delete time entries

Installation

npm install
npm run build

Configuration

Set your TMetric API token:

export TMETRIC_API_TOKEN="your_token_here"

Usage with Claude Code

Add the TMetric MCP server using the claude mcp add command. You can install at different scopes:

User Scope (Global - All Projects)

Available across all projects for your user:

One-liner:

claude mcp add --scope user tmetric-mcp --env TMETRIC_API_TOKEN=your_token_here -- node /path/to/tmetric-mcp-server/build/index.js

Interactive:

claude mcp add tmetric-mcp --scope user

When prompted, configure:

• Command: node
• Args: /path/to/tmetric-mcp-server/build/index.js
• Environment variables: TMETRIC_API_TOKEN=your_token_here

Project Scope (Specific Project)

Available only in the current project directory:

One-liner:

claude mcp add --scope project tmetric-mcp --env TMETRIC_API_TOKEN=your_token_here -- node /path/to/tmetric-mcp-server/build/index.js

Interactive:

claude mcp add tmetric-mcp --scope project

When prompted, configure with the same settings as above.

Local Scope (Current Directory)

Available only in the current working directory:

One-liner:

claude mcp add --scope local tmetric-mcp --env TMETRIC_API_TOKEN=your_token_here -- node /path/to/tmetric-mcp-server/build/index.js

Interactive:

claude mcp add tmetric-mcp --scope local

When prompted, configure with the same settings as above.

Alternative: Using npx (from GitHub)

You can run directly from GitHub with npx (no clone or build needed):

One-liner:

claude mcp add --scope user tmetric-mcp --env TMETRIC_API_TOKEN=your_token_here -- npx -y github:guglielmo/tmetric-minimal-mcp

Interactive:

claude mcp add tmetric-mcp --scope user

When prompted, configure:

• Command: npx
• Args: -y github:guglielmo/tmetric-minimal-mcp
• Environment variables: TMETRIC_API_TOKEN=your_token_here

Alternative: Using npx (from local path)

If you've cloned the repository locally:

One-liner:

claude mcp add --scope user tmetric-mcp --env TMETRIC_API_TOKEN=your_token_here -- npx -y /path/to/tmetric-mcp-server

Interactive:

claude mcp add tmetric-mcp --scope user

When prompted, configure:

• Command: npx
• Args: -y /path/to/tmetric-mcp-server
• Environment variables: TMETRIC_API_TOKEN=your_token_here

Available Tools

list_tmetric_projects()

Get list of available projects.

get_current_timer()

Check if a timer is running.

start_timer(project_id, task_name, task_url?)

Start tracking time on a project/task.

stop_timer()

Stop current timer and return time spent.

delete_time_entry(entry_id?)

Delete a time entry.

Development

# Watch mode
npm run watch

# Run directly with tsx
npm run dev

Testing

Running Tests

# Run all tests once
npm test

# Run tests in watch mode (re-runs on file changes)
npm run test:watch

# Run tests with coverage report
npm run test:coverage

# Run tests with interactive UI
npm run test:ui

Test Coverage

The project has comprehensive test coverage with:

• 100% statement coverage across all modules
• 97%+ branch coverage for edge cases
• Unit tests for all utility functions (utils.ts)
• Full integration tests for TMetric API client (tmetric-client.ts)
• Mocked HTTP requests using nock for reliable testing

See TESTING.md for detailed information about the testing strategy and how to write new tests.

Manual Testing

Test the MCP server with Claude Code by starting a conversation and using commands like:

• "List my TMetric projects"
• "Start timer on project 12345 for Issue #123: Fix bug"
• "What am I working on?"
• "Stop the timer"

Troubleshooting

"TMETRIC_API_TOKEN is required"

Make sure you've set the environment variable with your API token.

"Failed to initialize TMetric client"

Check that your API token is valid and you have network access to TMetric.

"Timer already running"

This is expected behavior. Stop the current timer before starting a new one.

Used By

This MCP server is a dependency for the following Claude Code skills:

• issue-time-tracking - Automates synchronized issue status tracking and time logging across GitLab/GitHub and TMetric
