📄 Publishing Guide

Prerequisites

• Node.js and npm installed

• npm account with access to the @zengwenliang scope

• Package built locally

Publishing Steps

1. Update version in package.json

   {
     "name": "@zengwenliang/mcp-server-sequential-thinking",
     "version": "0.6.4",
     "description": "MCP server for sequential thinking and problem solving"
   }

2. Use official npm registry

   npm config set registry https://registry.npmjs.org/

3. Login to npm

   npm login

   Follow the prompts to log in through your browser.

4. Check organization membership For scoped packages, ensure you're part of the scope:

   npm org ls your-org-name
   
   # For personal scopes, this is automatically created with your username

5. Build and publish

   npm run build
   
   # For first-time publishing a scoped package
   npm publish --access public
   
   # For subsequent updates
   npm publish

6. Verify publication

   npm view @zengwenliang/mcp-server-sequential-thinking

7. Commit your changes

   git add .
   git commit -m "feat(publish): 🚀 发布npm包@zengwenliang/mcp-server-sequential-thinking"
   git push

Version Updates

Use semantic versioning:

# For patches (bug fixes)
npm version patch

# For minor updates (features)
npm version minor

# For major updates (breaking changes)
npm version major

After updating the version, build and publish again:

   • NPM_TOKEN: Paste your npm access token value

   • DOCKERHUB_USERNAME: Enter your Docker Hub username

   • DOCKERHUB_TOKEN: Paste your Docker Hub access token

4. After adding all secrets, you should see all 3 listed in the "Actions secrets" list

Testing the Workflow

To test your automated publishing workflow:

1. In your GitHub repository, click the "Actions" tab

2. Find the "Publish Package" workflow in the left sidebar

3. Click the "Run workflow" button

4. Select the "main" branch from the branch dropdown

5. Click the green "Run workflow" button

6. Monitor the progress and results in the Actions tab

Note for 2FA Users: If you have Two-Factor Authentication enabled on your npm account, you must either:

• Use an "Automation" type token (recommended)

• Change 2FA settings to "Authorization only" (not recommended)

• Manually publish packages (not automated)

❗ Troubleshooting

If you encounter integration issues:

1. 🔧 Use the local build method with absolute path to the JS file

2. 📝 Verify file permissions: chmod +x dist/index.js

3. 🐳 Try Docker as an alternative

4. 📚 Consult Cursor's documentation for latest MCP integration methods
