My first MCP server

Development

Scripts

Build & Run

• npm start - Run the built application from dist/

• npm run start:dev - Run development server with ts-node

• npm run build - Build project using tsup (generates CommonJS output with sourcemaps)

Testing

• npm run test - Run Jest tests

• npm run test:watch - Run Jest in watch mode for development

• npm run test:coverage - Run tests with coverage report

Code Quality

• npm run lint - Run ESLint on source and test files

• npm run lint:fix - Fix ESLint issues automatically

• npm run format - Format code with Prettier

• npm run type-check - Run TypeScript type checking without emitting files

Maintenance

• npm run audit:check - Check for security vulnerabilities using audit-ci

• npm run dep:check - Check for outdated dependencies

• npm run dep:update - Update dependencies to latest versions

• npm run release - Create a release using standard-version

• npm run snapshot - Create a snapshot prerelease

Project Structure

Configuration

TypeScript

The project uses strict TypeScript configuration with enhanced checking:

• Path Mapping: Use #src/* aliases for clean imports

• Strict Mode: Enhanced type checking including noUncheckedIndexedAccess

• Target: ES2022 with source maps and declarations enabled

Build

Currently builds CommonJS only. ESM and type definitions can be enabled by modifying tsup.config.ts.

Testing

Jest is configured with:

• ts-jest preset for TypeScript support

• Node environment

• Path alias support (#src/ and #test/)

• Coverage collection from all src/ files

Git Hooks

Pre-commit hooks automatically:

• Run ESLint with auto-fix on staged files

• Format code with Prettier on staged files

• Validate commit messages using conventional commits

Pre-push hooks automatically:

• Run full ESLint checks on all source and test files

• Execute complete Jest test suite

• Check for outdated dependencies

• Perform security audit checks

Development Workflow

1. Make Changes: Edit files in src/ directory

2. Test: Run npm run test:watch for continuous testing

3. Lint: Code is automatically linted on save and commit

4. Build: Run npm run build to verify production build

5. Commit: Use conventional commit messages (enforced by commitlint)

Contributing

1. Install dependencies: npm install

2. Create a feature branch: git checkout -b feature/my-feature

3. Make your changes and add tests

4. Ensure all checks pass: npm run lint && npm run test && npm run build

5. Commit using conventional commits

6. Push and create a pull request
