Connect any MCP client with remote-server support directly to a URL in the table above. [Cloudflare AI Playground](https://playground.ai.cloudflare.com/) also accepts server URLs in its interface.

### Static API-Token Authentication

In addition to OAuth in interactive environments, all hosted remote MCP servers support standard Bearer token authentication with a Cloudflare API token. This is particularly useful for headless environments, CI pipelines, or persistent MCP configurations (such as Claude Code `.mcp.json` or Cursor `mcp.json`):

```json
{
"mcpServers": {
"cloudflare-api": {
"type": "http",
"url": "https://mcp.cloudflare.com/mcp",
"headers": {
"Authorization": "Bearer ${CLOUDFLARE_API_TOKEN}"
}
}
}
}
```

Ensure your API token has the appropriate read/write permissions for the specific domain or tools you intend to use.

## Using Cloudflare's MCP servers from the OpenAI Responses API

To use one of Cloudflare's MCP servers with [OpenAI's responses API](https://openai.com/index/new-tools-and-features-in-the-responses-api/), you will need to provide the Responses API with an API token that has the scopes (permissions) required for that particular MCP server.
