## Description
Deploy and manage Bult apps from AI coding agents.

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "bult": {
    "command": "npx",
    "args": ["-y","bult"]
  }
}
```

## Documentation & README

# @bultcloud/mcp-server

[![License: MIT](https://img.shields.io/badge/License-MIT-blue.svg)](LICENSE)

Official Model Context Protocol (MCP) server for [Bult.ai](https://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:

```bash
npm install -g @bultcloud/mcp-server
bult-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.

| Variable | Required | Description |
| --- | --- | --- |
| `BULT_API_URL` | Yes | Bult API base URL, `https://app.bult.ai`. |
| `BULT_API_TOKEN` | Yes | API 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
```

npm run lint     # type-check without emitting files
```

Project layout:

```text
src/index.ts          MCP server entrypoint
src/client.ts         Bult API client
src/tools/*.ts        MCP tool registrations by resource type
```

## 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](https://bult.ai/privacy-policy).
