概要

What is MCP Server Boilerplate?

MCP Server Boilerplate is a minimal reference implementation of a Model Context Protocol (MCP) server. It provides a starting point for developers to quickly build custom MCP servers and add their own tools, with examples demonstrating implementation patterns.

How to use MCP Server Boilerplate?

Clone the repository, run npm install and npm build, then add the server configuration to your MCP client's settings file using the absolute path to build/index.js. Optionally set environment variables under the "env" key, and start the dummy server with npx serve dummy-server. Restart the MCP client and run one of the provided prompt examples to verify the tools work.

Key features of MCP Server Boilerplate

  • Two sample tools: double_number and get_test_text
  • Demonstrates custom tool creation using the MCP SDK
  • Includes a dummy data server for testing
  • Multiple version branches showing progressive features
  • Uses Biomes for linting and formatting

Use cases of MCP Server Boilerplate

  • Learning how to build and extend an MCP server
  • Rapidly prototyping custom MCP tools
  • Testing MCP client integration with a simple server

よくある質問

1

What tools does the boilerplate include?

It includes `double_number` (doubles a given number) and `get_test_text` (fetches a string from the dummy server and displays the environment variable FOO).

2

How do I add a new custom tool?

Edit `src/index.ts` and follow the documented pattern: define the tool name, description, parameter schema with Zod, and a handler returning a `CallToolResult`.

3

What are the runtime requirements?

Node.js v23.11.0 or later, plus npm or yarn.

4

How do I set environment variables for the server?

Add an `"env"` object in the MCP client configuration file under the server entry, e.g., `"env": { "FOO": "BAR" }`.

5

Which MCP clients are supported?

Claude Code, VSCode, Windsurf, and Cursor are listed; AWS Bedrock is mentioned as untested.
