How Bult compares

Against every graded Developer tools MCP server, from our own scans and uptime checks. Updated after each scan run.

Safety score: 74/100; higher than 38% of 1,119 Developer tools servers
Tools: 24; the typical Developer tools server has 7
Tools that change things: 54%; typical: 5%. Fewer write tools means less an agent can break
GitHub stars: 1; more than 50% of 855 Developer tools servers
Downloads a week: 43; more than 31% of 436 Developer tools servers with a package

What its tools let an agent do: 10 read · 4 create · 4 change · 4 delete · 2 run or deploy

Install Bult in Claude Code, Cursor or VS Code

Runs npx -y @bultcloud/mcp-server on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add mcp-server -- npx -y @bultcloud/mcp-server

Add to Cursor

What the publisher says

From the Bult repository's README, as published. We do not edit it. Read it on GitHub

@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

MCP-compatible AI agents.

Deploy GitHub repositories, Docker images, databases, and app services from

stop, and discard changes.

Project lifecycle tools: list, inspect, create, update, delete, deploy, start,

Git-based deployments.

Service management for daemon and database services, including Docker image and

history.

Persistent volumes, route/domain mappings, templates, service logs, and build

where supported.

MCP tool annotations for read-only, idempotent, and destructive operations

clients.

Works over stdio with Claude Desktop, Claude Code, Cursor, Google Antigravity and other MCP-compatible

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
bult-mcp

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

npx -y @bultcloud/mcp-server

Configuration

The server reads its configuration from environment variables.

The server exits during startup if either variable is missing.

MCP Client Setup

Claude Desktop

Add the server to claudedesktopconfig.json.

Using npx:

{
  "mcpServers": {
    "bult": {
      "command": "npx",
      "args": ["-y", "@bultcloud/mcp-server"],
      "env": {
        "BULT_API_URL": "https://app.bult.ai",
        "BULT_API_TOKEN": "your-token"
      }
    }
  }
}

Claude Code

Using npx:

claude mcp add bult \
  -e BULT_API_URL=https://app.bult.ai \
  -e BULT_API_TOKEN=your-token \
  -- npx -y @bultcloud/mcp-server

Codex CLI

Using npx:

codex mcp add \
  --env BULT_API_URL=https://app.bult.ai \
  --env BULT_API_TOKEN=your-token \
  bult \
  -- npx -y @bultcloud/mcp-server
