The Deployer MCP server

Use The Deployer from Claude Code, Cursor, VS Code and other AI coding tools. Ask whether a repository will deploy, plan a deploy, see where your projects stand, read the latest deployment log, or put your latest code live, without leaving the editor.

The Deployer runs your app in your own DigitalOcean, AWS, Google Cloud or Azure account, so the cloud bills you directly.

Tools

To create a key, sign in to The Deployer, open Profile, and use API keys and AI coding tools. The page also shows these setups with your key filled in.

Setup

The hosted server needs nothing installed. Replace dpl_your_key with your key.

Keep the key out of files you commit. Put it in your user-level settings, or have your tool read it from an environment variable or a prompt, as shown below for project files.

Claude Code, for all your projects (stored in ~/.claude.json):

claude mcp add --transport http --scope user thedeployer https://app.thedploy.com/api/v1/mcp --header "Authorization: Bearer dpl_your_key"

To share the server in a project's .mcp.json, use "Authorization": "Bearer ${THEDEPLOYER_API_KEY}" as the header. Claude Code fills it in from each person's THEDEPLOYER_API_KEY environment variable.

Cursor, in ~/.cursor/mcp.json:

{
  "mcpServers": {
    "thedeployer": {
      "url": "https://app.thedploy.com/api/v1/mcp",
      "headers": { "Authorization": "Bearer dpl_your_key" }
    }
  }
}

In a project's .cursor/mcp.json, use "Authorization": "Bearer ${env:THEDEPLOYER_API_KEY}" instead, so Cursor reads the key from your environment.

VS Code, in .vscode/mcp.json. VS Code asks for the key the first time and stores it securely:

{
  "inputs": [
    { "type": "promptString", "id": "thedeployer-key", "description": "The Deployer API key", "password": true }
  ],
  "servers": {
    "thedeployer": {
      "type": "http",
      "url": "https://app.thedploy.com/api/v1/mcp",
      "headers": { "Authorization": "Bearer ${input:thedeployer-key}" }
    }
  }
}

The same works in your user configuration (run MCP: Open User Configuration).

Gemini CLI, in ~/.gemini/settings.json:

{
  "mcpServers": {
    "thedeployer": {
      "httpUrl": "https://app.thedploy.com/api/v1/mcp",
      "headers": { "Authorization": "Bearer dpl_your_key" }
    }
  }
}

Tools that start a local command (Cline, Windsurf and others) use this package, which needs Node.js 18 or newer. Add it to the tool's user-level MCP settings:

{
  "mcpServers": {
    "thedeployer": {
      "command": "npx",
      "args": ["-y", "thedeployer-mcp"],
      "env": { "THEDEPLOYER_API_KEY": "dpl_your_key" }
    }
  }
}

If your tool's configuration looks different, its MCP documentation has the equivalent fields: a URL with an Authorization header, or a command with an environment variable.

Proxies and company networks

With the hosted server, your AI tool makes the connection, so its own proxy settings apply.

This package uses Node.js, which ignores HTTPS_PROXY unless you turn that on. Add NODE_USE_ENV_PROXY next to it, which needs Node.js 22.21 or newer, or 24.0 or newer. (The --use-env-proxy flag does the same from Node.js 22.21 or 24.5.) On older versions, this package can't go through a proxy.

If your network inspects HTTPS with its own certificate, set NODE_EXTRA_CA_CERTS to that certificate's file (PEM):

"env": {
  "THEDEPLOYER_API_KEY": "dpl_your_key",
  "HTTPS_PROXY": "http://proxy.example.com:8080",
  "NODE_USE_ENV_PROXY": "1",
  "NODE_EXTRA_CA_CERTS": "/path/to/company-ca.pem"
}

What a key can and can't do

A key works only with The Deployer's MCP server, and only through its tools: check_repo, plan_deploy, status, logs (with secrets removed), redeploy and request_done_for_you. It can't touch your cloud or git credentials, your environment variables, your billing or your account settings, and it can't create more keys. The Deployer stores only a hash of it. Revoke a key on the Profile page at any time; use one key per tool or machine, so you can revoke one without touching the rest. Changing or resetting your password revokes all your keys.

redeploy changes a live app. Keep your tool asking you before it runs redeploy, rather than approving it automatically.

Tool answers come from your repositories and deployments. Treat them like any other text your agent reads.

How this package works

index.mjs is a bridge with no dependencies. It reads MCP messages from stdin, sends each one to The Deployer's hosted endpoint over HTTPS with your key, and writes the answers to stdout. The tools run on The Deployer, so this package doesn't change when they do.

Every request gets an answer. When The Deployer refuses one or can't be reached, the answer is an error that says why, such as a revoked key or a timeout. The bridge never follows redirects, and it never puts your key anywhere but the Authorization header.
