# Cloudflare Containers MCP server

> Start a sandboxed container to run code, shell commands and file operations from your assistant.

- Listing: https://mcp.tc/i/cloudflare-containers
- Connect: use the server's own URL `https://containers.mcp.cloudflare.com/mcp` (OAuth sign-in at the server); clients connect to it directly. The listing link is a page, not an MCP endpoint.
- Type: remote (Streamable HTTP)
- Auth: OAuth sign-in
- Category: [Developer Tools](https://mcp.tc/c/developer-tools)
- Vendor: Cloudflare
- Verified: yes, mcp.tc checked that this is the official server (https://mcp.tc/verify). It says who runs the server, not that it is safe.

## About

Gives an assistant a temporary sandbox container where it can run arbitrary code such as Node or Python, execute shell commands, and read, write, list and delete files in the working directory. Containers are ephemeral and keep no state; they are only guaranteed to last about 10 minutes.

Runs as a hosted remote server at https://containers.mcp.cloudflare.com/mcp using streamable HTTP. Sign in with your Cloudflare account through the OAuth flow in your browser when the client prompts. No local install is needed. The project is still a work in progress and more tools are planned.

## What it can do

- Start or restart an ephemeral sandbox container
- Run shell commands inside the container
- Write, read and delete files in the container
- List files in the work directory
- Check container connectivity
- Run Node or Python code in an isolated environment

## Example prompts

- "Create a visualization with matplotlib and run it in the container."
- "Clone this GitHub repo in the sandbox and run its tests."
- "Analyze this CSV data using Python in the container."
- "List the files in the container work directory."

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http cloudflare-containers https://containers.mcp.cloudflare.com/mcp
```

2. Start Claude Code, type `/mcp`, pick **cloudflare-containers** and choose **Authenticate**. A browser window opens for the Cloudflare sign-in.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Settings → Connectors** and click **Add custom connector**.

2. Name it **Cloudflare Containers** and paste this URL:

```url
https://containers.mcp.cloudflare.com/mcp
```

3. Click **Add**, then **Connect**, and sign in when Cloudflare asks.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Cloudflare%20Containers&connectorUrl=https%3A%2F%2Fcontainers.mcp.cloudflare.com%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://containers.mcp.cloudflare.com/mcp` and click **Add**.

3. Click **Connect** and sign in when Cloudflare asks.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, open **Settings → Security and login** and turn on **Developer mode**.

2. Go to `chatgpt.com/plugins` and click **+** to create an app for a remote MCP server.

3. Paste `https://containers.mcp.cloudflare.com/mcp` as the server URL and choose **OAuth**. ChatGPT sends you to Cloudflare to sign in.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=cloudflare-containers&config=eyJ1cmwiOiJodHRwczovL2NvbnRhaW5lcnMubWNwLmNsb3VkZmxhcmUuY29tL21jcCJ9>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "cloudflare-containers": {
      "url": "https://containers.mcp.cloudflare.com/mcp"
    }
  }
}
```

Cursor shows **Needs login** next to the server. Click it to sign in.

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=cloudflare-containers&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fcontainers.mcp.cloudflare.com%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"cloudflare-containers","type":"http","url":"https://containers.mcp.cloudflare.com/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "cloudflare-containers": {
      "type": "http",
      "url": "https://containers.mcp.cloudflare.com/mcp"
    }
  }
}
```

VS Code asks you to sign in the first time the server starts.

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "cloudflare-containers": {
      "serverUrl": "https://containers.mcp.cloudflare.com/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade and sign in when asked.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add cloudflare-containers --url https://containers.mcp.cloudflare.com/mcp
codex mcp login cloudflare-containers
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.cloudflare-containers]
url = "https://containers.mcp.cloudflare.com/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http cloudflare-containers https://containers.mcp.cloudflare.com/mcp
```

Then, inside Gemini CLI, run `/mcp auth cloudflare-containers` to sign in.

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "cloudflare-containers": {
      "type": "http",
      "url": "https://containers.mcp.cloudflare.com/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://containers.mcp.cloudflare.com/mcp`.
