Overview

AI-generated overview

Bult's official MCP server lets an AI coding agent deploy and operate Bult.ai cloud hosting: projects, services, volumes, routes, logs and builds.

What you can do
List, inspect, create, update, delete, deploy, start, stop and discard projects, with version snapshots on deploy and template application and listing for projects and services, including daemon and database services with Docker image or Git-based deployments, plus start, stop and rebuild control, and persistent volumes with name and size updates, irreversible wipes and deletion, and domain or path routes for services, and service logs with cursor pagination and build history.
When to use it
Use it when you want an AI coding agent to deploy a GitHub repository, the current project or a Docker image to Bult, create a database service or public route, or check logs and build history to debug a failed deployment.
Requirements
Runs locally over stdio via npx or a global npm install; needs Node.js 18 or newer, a Bult API token in BULT_API_TOKEN and the API base URL in BULT_API_URL. The server exits at startup if either variable is missing. Network access to the Bult API is required.
Before you install
BULT_API_TOKEN grants access to your Bult resources; keep it out of source control, shell history, issue reports and screenshots, and prefer scoped or rotatable tokens. Several tools create, delete, deploy, stop or irreversibly wipe resources, so review tool calls before approving destructive actions. Requests, including logs and configuration, are sent to Bult.ai.

Installation

In SourceWeft

  1. Open Bult in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

[License: MIT]

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.

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:

bash
npm install -g @bultcloud/mcp-serverbult-mcp

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

bash
npx -y @bultcloud/mcp-server

Configuration

The server reads its configuration from environment variables.

VariableRequiredDescription
BULT_API_URLYesBult API base URL, https://app.bult.ai.
BULT_API_TOKENYesAPI token used for Bearer authentication.

The server exits during startup if either variable is missing.

MCP Client Setup

Claude Desktop

Add the server to claude_desktop_config.json.

Using npx:

json
{  "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:

bash
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:

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

Security

BULT_API_TOKEN grants access to your Bult resources. Keep it out of source control, shell history, issue reports, and screenshots. Prefer scoped or rotatable tokens when available.

Some tools can create, delete, deploy, stop, or wipe resources. Review tool calls from your MCP client before approving destructive actions.

Privacy Policy

This MCP server connects your MCP client to Bult.ai using the API token you provide. Requests are sent to Bult.ai to perform actions such as listing projects, deploying services, managing routes and volumes, and reading logs.

The server does not store your API token. Tokens are passed through your MCP client configuration or extension settings. For Bult.ai data handling practices, see the Bult.ai Privacy Policy.
