Official Model Context Protocol (MCP) server for Bult. It lets MCP clients manage Bult projects, services, volumes, routes, templates, deployments, logs, and builds through the Bult API.

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
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.
Add the server to claude_desktop_config.json.

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.
