    • Description: MCP server for Google Cloud Dataproc operations

  3. Save credentials:

    • Copy your Client ID
    • Generate and copy your Client Secret

Step 3: Configure the Server

Create config/claude-ai-config.json:

{
  "profileManager": {
    "rootConfigPath": "./profiles",
    "profileScanInterval": 300000
  },
  "clusterTracker": {
    "stateFilePath": "./state/dataproc-state.json",
    "stateSaveInterval": 60000
  },
  "authentication": {
    "impersonateServiceAccount": "your-service-account@your-project.iam.gserviceaccount.com",
    "projectId": "your-project-id",
    "region": "us-central1",
    "preferImpersonation": true,
    "useApplicationDefaultFallback": true,
    "useOAuthProxy": true,
    "oauthProvider": "github",
    "githubOAuth": {
      "clientId": "YOUR_GITHUB_CLIENT_ID",
      "clientSecret": "YOUR_GITHUB_CLIENT_SECRET",
      "redirectUri": "http://localhost:8080/auth/github/callback",
      "scopes": ["read:user", "user:email"]
    }
  },
  "httpServer": {
    "port": 8080,
    "httpsPort": 8443,
    "enableHttps": true,
    "enableOAuthProxy": true,
    "host": "localhost"
  },
  "defaultParameters": {
    "defaultEnvironment": "production",
    "environments": [
      {
        "environment": "production",
        "parameters": {
          "projectId": "your-project-id",
          "region": "us-central1"
        }
      }
    ]
  }
}

Replace these values:

  • YOUR_GITHUB_CLIENT_ID - From Step 2
  • YOUR_GITHUB_CLIENT_SECRET - From Step 2
  • your-service-account@your-project.iam.gserviceaccount.com - Your service account
  • your-project-id - Your Google Cloud project ID

Step 4: Generate SSL Certificates

# Generate trusted certificates
npm run ssl:generate

# Verify certificates were created
ls -la certs/
# Should show: localhost-cert.pem and localhost-key.pem

Step 5: Start the Services

Open two terminals:

Terminal 1 - Start MCP Server:

DATAPROC_CONFIG_PATH=config/claude-ai-config.json npm start -- --http --oauth --port 8080

Terminal 2 - Start Cloudflare Tunnel:

cloudflared tunnel --url https://localhost:8443 --origin-server-name localhost --no-tls-verify

Look for this output in Terminal 2:

2024-06-19T14:30:00Z INF +--------------------------------------------------------------------------------------------+
2024-06-19T14:30:00Z INF |  Your quick Tunnel has been created! Visit it at (it may take some time to be reachable):  |
2024-06-19T14:30:00Z INF |  https://abc123-def456.trycloudflare.com                                                   |
2024-06-19T14:30:00Z INF +--------------------------------------------------------------------------------------------+

Copy your tunnel URL (e.g., https://abc123-def456.trycloudflare.com)

Step 6: Connect Claude.ai

  1. Open Claude.ai in your browser

  2. Go to Settings → MCP Servers (or similar)

  3. Add new MCP server:

    • Name: Dataproc MCP Server
    • URL: wss://YOUR-TUNNEL-URL/mcp (replace with your tunnel URL from Step 5)
    • Protocol: websocket

  4. Save and connect

  5. Verify connection - Should show "Connected" status

Test Your Setup

Try these commands in Claude.ai:

Basic Test

What Dataproc tools are available to me?

List Clusters

Show me all my Google Cloud Dataproc clusters

Create a Cluster

Create a small Dataproc cluster named "test-cluster" for development

Submit a Query

Submit a Hive query to count rows in my data table

🔧 Detailed Setup Guide

HTTPS Setup

The MCP Dataproc Server now supports HTTPS to comply with OAuth authorization requirements. Claude Desktop requires all authorization endpoints to be served over HTTPS per the MCP Authorization specification (line 303: "All authorization endpoints MUST be served over HTTPS").

Configuration

The server configuration supports the following HTTPS options in config/server.json:

{
  "httpServer": {
    "port": 8080,
    "httpsPort": 8443,
    "enableHttps": true,
    "enableOAuthProxy": true,
    "host": "localhost"
  }
}

Update your OAuth configuration to use HTTPS URLs in config/oauth-server.json:

{
  "authentication": {
    "oauthProxyRedirectUris": [
      "https://localhost:8443/callback",
      "http://localhost:8080/callback"
    ]
  },
  "httpServer": {
    "port": 8080,
    "httpsPort": 8443,
    "enableHttps": true,
    "enableOAuthProxy": true
  }
}

OAuth Endpoints

The following OAuth endpoints are now available over HTTPS:

Discovery Endpoints
  • https://localhost:8443/.well-known/oauth-authorization-server
  • https://localhost:8443/.well-known/openid_configuration
Authorization Endpoints
  • https://localhost:8443/authorize - Authorization endpoint
  • https://localhost:8443/token - Token endpoint
  • https://localhost:8443/register - Dynamic client registration
  • https://localhost:8443/revoke - Token revocation
GitHub OAuth (if configured)
  • https://localhost:8443/auth/github - GitHub authorization
  • https://localhost:8443/auth/github/callback - GitHub callback
  • https://localhost:8443/auth/github/token - GitHub token exchange

Testing HTTPS

Test with curl
# Test HTTPS MCP endpoint (ignore certificate warnings)
curl -k https://localhost:8443/health

# Test OAuth discovery
curl -k https://localhost:8443/.well-known/oauth-authorization-server
Test with MCP Inspector

MCP Inspector can connect to both HTTP and HTTPS endpoints:

# HTTP endpoint (for development)
npx @modelcontextprotocol/inspector http://localhost:8080/mcp

# HTTPS endpoint (for Claude Desktop compatibility)
npx @modelcontextprotocol/inspector https://localhost:8443/mcp

Claude Desktop Integration

Claude Desktop requires HTTPS for OAuth authorization. Configure your MCP client settings to use:

{
  "mcpServers": {
    "dataproc": {
      "command": "node",
      "args": ["/path/to/dataproc-server/build/index.js", "--http", "--oauth"],
      "env": {
        "DATAPROC_CONFIG_PATH": "/path/to/config/oauth-server.json"
      }
    }
  }
}

Then connect to: https://localhost:8443/.well-known/oauth-authorization-server

Backward Compatibility

The server maintains backward compatibility:

  • HTTP endpoints: Still available on port 8080 for development tools
  • MCP Inspector: Can use either HTTP or HTTPS endpoints
  • Legacy configurations: Existing HTTP-only configurations continue to work

Trusted SSL Certificates

This section explains how to use trusted SSL certificates to resolve the "MCP error -32000: Connection closed" issue when connecting Claude.ai web app to your MCP server.

Problem

Claude.ai web app fails to connect to MCP servers using self-signed certificates because browsers reject self-signed certificates for WebSocket connections from web applications. This results in connection errors like:

MCP error -32000: Connection closed

Solution

We use mkcert to generate locally trusted certificates that browsers automatically accept, eliminating certificate warnings and connection issues.

Installation Requirements

Install mkcert

macOS:

brew install mkcert

Linux (Ubuntu/Debian):

# Install certutil
sudo apt install libnss3-tools

# Download and install mkcert
curl -JLO "https://dl.filippo.io/mkcert/latest?for=linux/amd64"
chmod +x mkcert-v*-linux-amd64
sudo cp mkcert-v*-linux-amd64 /usr/local/bin/mkcert

Windows:

# Using Chocolatey
choco install mkcert

# Or download from GitHub releases
# https://github.com/FiloSottile/mkcert/releases
Install Local Certificate Authority

The certificate generation script will automatically install the local CA, but you can also do it manually:

# Install local CA (you may be prompted for password)
mkcert -install

# Verify CA installation
mkcert -CAROOT

Certificate Details

The generated certificates are valid for:

  • localhost
  • 127.0.0.1
  • ::1 (IPv6 localhost)

Certificate files:

  • Private key: certs/localhost-key.pem
  • Certificate: certs/localhost-cert.pem
  • Validity: 2+ years from generation date

Usage with Claude.ai Web App

1. Configure MCP Server Connection

In Claude.ai web app, add your MCP server with the HTTPS WebSocket URL:

{
  "name": "Dataproc MCP Server",
  "url": "wss://localhost:8443/mcp",
  "protocol": "websocket"
}
2. Verify Connection
  1. Open Claude.ai in your browser
  2. Navigate to MCP server settings
  3. Add the server configuration above
  4. The connection should establish without certificate warnings
  5. You should see the server listed as "Connected"

Security Notes

  • Development only: These certificates are for local development
  • Local CA: The local CA is only trusted on your machine
  • Automatic cleanup: Certificates expire automatically (2+ years)
  • No external trust: Other machines won't trust these certificates

Advanced Configuration

Custom Certificate Domains

To generate certificates for additional domains:

# Generate certificates for custom domains
mkcert -key-file certs/custom-key.pem -cert-file certs/custom-cert.pem \
  localhost 127.0.0.1 ::1 myapp.local custom.dev
Certificate Renewal

Certificates are valid for 2+ years. To renew:

# Remove old certificates
rm -f certs/localhost-*.pem

# Generate new certificates
node scripts/generate-ssl-cert.js
Uninstall Local CA

To remove the local CA from your system:

# Uninstall local CA
mkcert -uninstall

# Remove certificate files
rm -rf certs/

Integration with CI/CD

For automated testing environments:

# Install mkcert in CI
curl -JLO "https://dl.filippo.io/mkcert/latest?for=linux/amd64"
chmod +x mkcert-v*-linux-amd64
sudo cp mkcert-v*-linux-amd64 /usr/local/bin/mkcert

# Generate certificates in CI
mkcert -install
node scripts/generate-ssl-cert.js

OAuth Authentication Setup

GitHub OAuth Configuration

  1. Create OAuth App (as shown in Quick Start)

  2. Configure server with GitHub credentials

  3. Test OAuth flow:

    # Check server health
curl http://localhost:8080/health

# Should return: {"status":"healthy","oauthEnabled":true}

OAuth Endpoints

The server provides these OAuth endpoints:

  • GET /auth/github - Initiate OAuth flow
  • GET /auth/github/callback - OAuth callback handler
  • GET /auth/github/status - Check authentication status
  • POST /auth/github/logout - Logout and revoke token

Cloudflare Tunnel Configuration

Basic Tunnel Setup

# Start tunnel with HTTPS backend
cloudflared tunnel --url https://localhost:8443 --origin-server-name localhost --no-tls-verify

Advanced Tunnel Configuration

Create cloudflared-config.yml:

tunnel: your-tunnel-id
credentials-file: /path/to/credentials.json

ingress:
  - hostname: your-domain.com
    service: https://localhost:8443
    originRequest:
      originServerName: localhost

🔍 Troubleshooting

Common Issues

1. "MCP error -32000: Connection closed"

Cause: Certificate or tunnel issues Solution:

# Regenerate certificates
rm -rf certs/
npm run ssl:generate

# Restart services
# Terminal 1: Restart MCP server
# Terminal 2: Restart Cloudflare tunnel

2. "OAuth proxy enabled but missing configuration"

Cause: Missing GitHub OAuth configuration Solution:

# Verify config file has githubOAuth section
cat config/claude-ai-server.json | grep -A 10 "githubOAuth"

# Ensure oauthProvider is set to "github"

3. "Invalid GitHub token"

Cause: Incorrect GitHub credentials Solution:

  • Verify Client ID and Secret in GitHub OAuth app
  • Ensure redirect URI matches exactly: http://localhost:8080/auth/github/callback

4. Tunnel Connection Issues

Cause: Cloudflare tunnel connectivity Solution:

# Test local HTTPS endpoint
curl -k https://localhost:8443/health

# Check tunnel logs for errors
cloudflared tunnel --url https://localhost:8443 --origin-server-name localhost --no-tls-verify --loglevel debug

Certificate Not Trusted

If browsers still show certificate warnings:

  1. Regenerate certificates:

    # Remove existing certificates
rm -f certs/localhost-*.pem

# Regenerate with mkcert
node scripts/generate-ssl-cert.js

  2. Reinstall local CA:

    mkcert -uninstall
mkcert -install

  3. Restart browser after certificate changes

Connection Still Fails

  1. Check server is running on HTTPS:

    curl -I https://localhost:8443/health

  2. Verify WebSocket endpoint:

    # Should connect without certificate errors
wscat -c wss://localhost:8443/mcp --subprotocol mcp

  3. Check browser console for detailed error messages

mkcert Not Found

If you get "mkcert not found" errors:

  1. Install mkcert using the instructions above
  2. Verify installation: 
    mkcert -version
  3. Add to PATH if necessary

Certificate Generation Issues

If npm run ssl:generate fails:

  1. Check OpenSSL installation:

    openssl version

  2. Install OpenSSL if missing:

  3. Manual certificate generation:

    mkdir -p certs
openssl genrsa -out certs/localhost-key.pem 2048
openssl req -new -x509 -key certs/localhost-key.pem -out certs/localhost-cert.pem -days 365 -subj "/C=US/ST=Development/L=Localhost/O=MCP Dataproc Server/CN=localhost"

HTTPS Connection Issues

  1. Port conflicts: Ensure port 8443 is not in use by another service
  2. Firewall: Allow incoming connections on port 8443
  3. Certificate trust: Add the certificate to your system's trusted certificates for seamless browsing

OAuth Authorization Issues

  1. Verify HTTPS URLs: Ensure all OAuth redirect URIs use HTTPS
  2. Check certificate validity: Certificates must be valid and not expired
  3. Browser console: Check for mixed content warnings or certificate errors
