🔍 Smart Features

🧠 Auto-Lookup Intelligence

The server automatically finds required resource IDs, eliminating 404 errors:

// Before: Complex resource ID hunting
{
  "tool": "get_todo_lists",
  "arguments": {
    "project_id": "123456",
    "todoset_id": "789012"  // ← Hard to find manually
  }
}

// After: Simple auto-lookup
{
  "tool": "get_todo_lists", 
  "arguments": {
    "project_id": "123456"  // ← Auto-finds todoset ID
  }
}

📈 URL Intelligence

Parse any Basecamp URL to extract project and resource information:

// Input: https://3.basecamp.com/999999/buckets/123456/todolists/789012
// Output: 
{
  "account_id": "999999",
  "project_id": "123456", 
  "resource_type": "todolists",
  "resource_id": "789012",
  "suggested_tools": ["get_todos", "create_todo"]
}

🔄 Multi-Authentication Support

Flexible authentication with priority order:

Arguments: access_token parameter (highest priority)
Headers: Authorization: Bearer TOKEN
Environment: BASECAMP_ACCESS_TOKEN (fallback)

⚙️ Configuration

Environment Variables

| Variable | Description | Required | |----------|-------------|----------| | BASECAMP_ACCOUNT_ID | Your Basecamp account ID | ✅ | | BASECAMP_CLIENT_ID | OAuth client ID | ✅ (for OAuth) | | BASECAMP_CLIENT_SECRET | OAuth client secret | ✅ (for OAuth) | | BASECAMP_ACCESS_TOKEN | Fallback access token | ⚠️ (optional) |

wrangler.toml Example

name = "my-basecamp-mcp-server"
main = "index.ts"
compatibility_date = "2024-08-05"

[vars]
BASECAMP_ACCOUNT_ID = "999999999"

# Note: v7.5 no longer requires KV namespace binding
# All authentication is handled via environment variables

🔒 Security Best Practices

Authentication Security

Individual Tokens: Each user maintains their own OAuth token
Secure Headers: All requests use proper authorization headers
Token Validation: Automatic token validation and error handling
Environment Isolation: Production secrets separate from code

API Security

Rate Limiting: Automatic compliance with Basecamp API limits
Request Validation: Input sanitization and type checking
Error Handling: Secure error messages without data leaks
CORS Configuration: Proper cross-origin resource sharing

🚀 Deployment Options

Cloudflare Workers (Recommended)

Global Edge Network: Sub-100ms response times worldwide
Automatic Scaling: Handle unlimited traffic
Built-in Security: DDoS protection, WAF, SSL
Cost Effective: Pay per request, no idle costs

Alternative Platforms
