🛠️ Development

Prerequisites

  • Node.js >= 20
  • pnpm >= 9

Setup

git clone https://github.com/arvoreeducacao/arvore-mcp-servers.git
cd mcp-servers
pnpm install

Build all packages

pnpm build

Run tests

pnpm test

Run tests with coverage

pnpm test:cov

Lint

pnpm lint

Development mode

Run a specific package in development mode:

cd packages/aws-secrets-manager
pnpm dev

📝 Adding a New Package

  1. Create a new directory in packages/
  2. Follow the structure of existing packages
  3. Update the root README.md
  4. Add package-specific documentation

🚢 Publishing

Automatic Publishing

This monorepo uses GitHub Actions for automatic publishing to npm. Publishing happens in these scenarios:

1. Push to main branch

Only the packages changed in the push are published when code is merged to main (after CI passes). The publish job detects which packages/<name> directories were touched via git diff against the previous commit and runs npm publish only for those. Remember to bump the version in the changed package's package.json before merging, otherwise npm will skip it as already published.

2. Manual workflow dispatch

You can manually trigger publishing for a specific package:

  • Go to GitHub Actions
  • Select "Publish Packages" workflow
  • Click "Run workflow"
  • Specify package name (e.g., @arvoretech/aws-secrets-manager-mcp)
  • Choose version bump type (major, minor, or patch)

Setup Requirements

To enable automatic publishing, add these secrets to your GitHub repository:

  1. NPM_TOKEN: Required for publishing to npm

  2. CODECOV_TOKEN (optional): For coverage reports

Manual Publishing

If needed, you can publish manually (requires authentication):

# Publish all packages
pnpm -r publish

# Publish specific package
cd packages/aws-secrets-manager
npm publish

Version Management

To bump versions:

# In a specific package directory
cd packages/aws-secrets-manager
pnpm version patch  # or minor, major
