> ## Agent Instructions
> Unkey is two separate products. Compute builds, deploys, and runs apps behind a gateway. API Management issues API keys, enforces rate limits, manages identities and permissions, and reports usage. Say which product a page belongs to; a reader can use either without the other.
> Every Unkey API endpoint is an HTTP POST to https://api.unkey.com/v2/{service}.{procedure} with a root key in the Authorization: Bearer header. Root keys are workspace scoped.
> Error codes have the form err:{system}:{category}:{specific} and each has a page at /errors/{system}/{category}/{specific}.
> The word environment means production or preview in Compute. Rate limiting has four meanings on this site; the glossary lists them.

# Connect other MCP clients

> Set up the Unkey MCP servers in VS Code, Claude Desktop, Codex CLI, or any other MCP client.

Each example adds the Unkey server. For the Compute server, swap in `https://mcp.unkey.com/mcp/compute`. You need a root key for your assistant. See [Create a root key](/docs/platform/ai-coding/mcp-servers#create-a-root-key).

## VS Code

Add the server to `.vscode/mcp.json` in your project:

```json theme={"system"}
{
  "inputs": [
    {
      "type": "promptString",
      "id": "unkey-root-key",
      "description": "Unkey root key",
      "password": true
    }
  ],
  "servers": {
    "unkey": {
      "type": "http",
      "url": "https://mcp.unkey.com/mcp/v2",
      "headers": {
        "Mcp-Unkey-V2-Bearer": "${input:unkey-root-key}"
      }
    }
  }
}
```

VS Code asks for your root key the first time the server starts and stores it for you. To add the docs, open the menu next to **Copy page** on any docs page and choose **Connect to VS Code**.

## Claude Desktop

Claude Desktop's custom connectors can't send headers, so it connects through `mcp-remote`, which needs Node.js.

1. Go to **Settings > Developer > Local MCP Servers > Edit config** to open `claude_desktop_config.json`.
2. Add the server and replace the placeholder with your root key:

```json theme={"system"}
{
  "mcpServers": {
    "unkey": {
      "command": "npx",
      "args": [
        "mcp-remote@0.1.25",
        "https://mcp.unkey.com/mcp/v2",
        "--header",
        "Mcp-Unkey-V2-Bearer:${UNKEY_ROOT_KEY}"
      ],
      "env": {
        "UNKEY_ROOT_KEY": "<your root key>"
      }
    }
  }
}
```

3. Save the file and restart Claude Desktop.

## Codex CLI

```bash theme={"system"}
codex mcp add unkey --url "https://mcp.unkey.com/mcp/v2"
```

Codex can't set headers from the command line. Open `~/.codex/config.toml` and add this line to the `[mcp_servers.unkey]` entry the command created, so Codex reads the key from `UNKEY_ROOT_KEY`:

```toml theme={"system"}
env_http_headers = { "Mcp-Unkey-V2-Bearer" = "UNKEY_ROOT_KEY" }
```

Restart Codex to load the server.

## Any other client

Any client that connects to remote MCP servers over HTTP and can send a custom header works. Give it the server URL and the `Mcp-Unkey-V2-Bearer` header with your root key. The [install page](https://mcp.unkey.com/mcp/v2/install) also has snippets for opencode and Antigravity.
