README
MCP Starter Kit
Minimal TypeScript MCP server template you can clone and customize.
This starter includes:
- one example tool registration
- Zod input validation
- stdio transport setup
- dotenv loading for local environment variables
Quick Start
1) Install dependencies
npm install
2) Configure environment variables (optional)
Create a .env file in the project root. Add only the variables your tools need.
GENERIC_API_KEY=your_api_key_here
3) Build the server
npm run build
This generates build/index.js.
Connect in an MCP Client
Add this server to your MCP client config.
Example configuration:
{
"mcpServers": {
"mcp-starter-kit": {
"command": "node",
"args": [
"--env-file=<PROJECT_ROOT>/.env",
"<PROJECT_ROOT>/build/index.js"
]
}
}
}
Then restart your MCP client.
Customize
Start editing src/index.ts:
- rename the sample tool (
tool_name) - define a useful input schema
- replace the sample handler logic with your own behavior
Development Notes
- Build output is written to
build/. - Keep secrets in
.env(already ignored by Git). - Update
.env.examplewhenever you add required environment variables.
