Buildable

@bldbl/mcp

Official MCP client for Buildable - AI-powered development platform that makes any project buildable

This package enables AI assistants (Claude, GPT, etc.) to work directly with Buildable projects using the Model Context Protocol (MCP). AI assistants can get project context, manage tasks, track progress, and communicate with human developers.

🌟 What is Buildable?

• AI-Generated Build Plans: Comprehensive project roadmaps with implementation details
• Smart Task Management: Automated task breakdown with dependencies and priorities
• AI Assistant Integration: Direct integration with Claude, GPT, and other AI assistants
• Real-time Collaboration: Seamless human-AI collaboration on complex projects
• Progress Tracking: Live monitoring of development progress and blockers

🚀 Features

• Full Project Integration: Get complete project context, plans, and task details
• Autonomous Task Management: Start, update progress, and complete tasks
• Human Collaboration: Create discussions for questions and blockers
• Real-time Progress Tracking: Live updates and status monitoring

    "buildable": {
      "command": "npx",
      "args": ["-y", "@bldbl/mcp"],
      "env": {
        "BUILDABLE_API_KEY": "bp_your_api_key_here",
        "BUILDABLE_PROJECT_ID": "your-project-id",

Minimal setup - only API URL is auto-detected.

✨ For Cursor AI:

Option 1: One-Click Setup (Recommended)

1. Go to your project on bldbl.dev
2. Navigate to Integrations
3. Click "Add to Cursor" - Done! 🎉

Option 2: Manual Configuration Add this to your Cursor AI config file:

{
  "mcpServers": {
    "buildable": {
      "command": "npx",
      "args": ["-y", "@bldbl/mcp"],
      "env": {
        "BUILDABLE_API_KEY": "bp_your_api_key_here",
        "BUILDABLE_PROJECT_ID": "your-project-id",
        "BUILDABLE_AI_ASSISTANT_ID": "cursor-ide"
      }
    }
  }
}

Minimal setup - only API URL is auto-detected.

Step 4: Start AI-Powered Development!

Once configured, your AI assistant has access to these powerful tools:

• 🏗️ get_project_context - Understand your entire project structure
• 📋 get_next_task - Find what to work on next based on priorities
• ▶️ start_task - Begin working on a specific task
• 📊 update_progress - Report detailed progress updates
• ✅ complete_task - Mark tasks finished with comprehensive notes
• 💬 create_discussion - Ask questions when you need human input
• 🔍 health_check - Verify connection to Buildable

💡 Example AI Conversation:

You: "What should I work on next in my project?"

AI: *calls get_project_context & get_next_task*
    "I see you're building a React dashboard app. The next 
     high-priority task is 'Implement user authentication'. 
     Should I start working on it?"

You: "Yes, go ahead!"

AI: *calls start_task*
    "Perfect! I'm starting the authentication task. I'll use 
     NextAuth.js with GitHub OAuth. Let me break this down:
     1. Install dependencies
     2. Set up NextAuth config  
     3. Create login/logout components
     4. Add protected routes
     
     I'll update you on progress as I work!"

[AI works and calls update_progress periodically]

AI: *calls update_progress*
    "Progress update: 75% complete! I've implemented:
     ✅ NextAuth.js configuration
     ✅ GitHub OAuth provider setup  
     ✅ Login/logout components
     🔄 Currently working on: Protected route middleware
     
     Should I continue with the remaining work?"

🔧 Advanced Configuration

Environment Variables

3 environment variables are recommended for proper AI assistant tracking:

export BUILDABLE_API_KEY="bp_your_api_key_here"           # Your API key (required)
export BUILDABLE_PROJECT_ID="your-project-id"             # Target project (required)
export BUILDABLE_AI_ASSISTANT_ID="my-ai-assistant"        # AI Assistant ID (recommended)

# Optional (has smart default):
# export BUILDABLE_API_URL="https://bldbl.dev/api"        # API endpoint (default)

Why AI Assistant ID matters: This helps you track which AI assistant is doing what work in your project dashboard.

CLI Usage

You can also run the MCP server directly:

# Install globally and use bldbl command
npm install -g @bldbl/mcp
bldbl

# Or run with npx (no installation needed)
npx @bldbl/mcp

Multiple Projects

To work with multiple Buildable projects, create different MCP server configs:

{
  "mcpServers": {
    "buildable-frontend": {
      "command": "npx",
      "args": ["-y", "@bldbl/mcp"],
      "env": {
        "BUILDABLE_API_KEY": "bp_frontend_key_here",
        "BUILDABLE_PROJECT_ID": "frontend-project-id",
        "BUILDABLE_AI_ASSISTANT_ID": "claude-frontend"
      }
    },
    "buildable-backend": {
      "command": "npx", 
      "args": ["-y", "@bldbl/mcp"],
      "env": {
        "BUILDABLE_API_KEY": "bp_backend_key_here",
        "BUILDABLE_PROJECT_ID": "backend-project-id",
        "BUILDABLE_AI_ASSISTANT_ID": "claude-backend"
      }
    }
  }
}
