概览

What is Simple Timer MCP Server?

Simple Timer MCP Server is an MCP (Model Context Protocol) server that provides interval timing functionality using token-based time tracking. It is designed as a beginner-friendly example of an MCP server, demonstrating core development concepts through minimal, practical functionality. It stores timer data persistently using an SQLite database.

How to use Simple Timer MCP Server?

Clone the repository, install dependencies with yarn install, build the TypeScript source with yarn build, then start the server with yarn start. Integrate with an MCP host by configuring the execution command node dist/index.js or the full path to that file. The server exposes four tools: start_timer, check_timer, delete_timer, and list_timers.

Key features of Simple Timer MCP Server

  • Token-based timers using unique string identifiers.
  • Elapsed time calculation with millisecond precision.
  • Human-readable output format for elapsed time.
  • Ability to delete and list active timers.
  • Persistent storage via better-sqlite3 database.

Use cases of Simple Timer MCP Server

  • Tracking time spent on individual tasks or projects by token.
  • Learning MCP server development with a simple, hands-on example.
  • Monitoring elapsed time within an AI assistant workflow.
  • Demonstrating timer functionality in MCP-compatible clients.

常见问题

1

What runtime does Simple Timer MCP Server require?

Node.js version 18.x or later, and Yarn v1.x or later.

2

How are timers identified?

Each timer is identified by a unique string token provided when starting the timer.

3

Does the server store timers persistently?

Yes. Timer data is stored in an SQLite database file (`timer.db`) located in the project root directory.

4

What transport does the server use?

The server uses `StdioServerTransport` for MCP communication.

5

Can I get elapsed time in a human-readable format?

Yes. Use the `check_timer` tool with the optional `format` argument set to `"human_readable"` (e.g., "1 hour, 30 minutes, 45 seconds").
