@bultcloud/mcp-server

Official Model Context Protocol (MCP) server for Bult.ai, a DevOps platform and cloud hosting Platform-as-a-Service for deploying apps, GitHub repositories, Docker images, databases, and services with AI agents.

Use Bult MCP with Claude Desktop, Claude Code, Cursor, Codex, and other MCP-compatible clients to deploy apps, manage cloud infrastructure, inspect logs, and troubleshoot deployments through the Bult API.

Demo

Features

• Deploy GitHub repositories, Docker images, databases, and app services from MCP-compatible AI agents.
• Project lifecycle tools: list, inspect, create, update, delete, deploy, start, stop, and discard changes.
• Service management for daemon and database services, including Docker image and Git-based deployments.
• Persistent volumes, route/domain mappings, templates, service logs, and build history.
• MCP tool annotations for read-only, idempotent, and destructive operations where supported.
• Works over stdio with Claude Desktop, Claude Code, Cursor, Google Antigravity and other MCP-compatible clients.

When to use Bult MCP

Use Bult MCP when you want an AI coding agent to deploy and operate cloud hosting resources for you. Common workflows include deploying a GitHub repo from Cursor, deploying the current project from Claude Code, launching a Docker image, creating a database service, adding a public route, checking build logs, and debugging failed deployments.

Requirements

• Node.js 18 or newer.
• Bult API token.

Installation

If you install the package globally, use the bult-mcp binary:

npm install -g @bultcloud/mcp-server

You can also run it with npx from MCP client configs:

npx -y @bultcloud/mcp-server
