What is Cloudflare MCP Server

Cloudflare MCP Server is a set of standardized servers implementing the Model Context Protocol (MCP), designed to facilitate communication between large language models (LLMs) and Cloudflare services. These servers allow clients to manage configurations, process data, make suggestions, and execute changes within Cloudflare’s various offerings, including application development, security, and performance.

Use cases

MCP servers can be used for a variety of tasks such as building and managing Cloudflare Workers, gaining insights from application logs, optimizing DNS performance, monitoring digital experiences, querying audit logs, and accessing global internet traffic data. This versatility makes them suitable for developers, data analysts, and IT professionals seeking to enhance their Cloudflare capabilities.

How to use

To access the Cloudflare MCP servers, users can connect through an MCP client with first-class support for remote servers or configure their client through a configuration file using mcp-remote. For specific use cases, like using the Browsers Rendering server with OpenAI’s Responses API, users must create an API token with the necessary permissions in the Cloudflare dashboard.

Key features

Key features of the Cloudflare MCP servers include access to comprehensive documentation, tools for managing Workers applications, observability for logging and analytics, and integration capabilities with other cloud services. The servers also support functionalities like sandbox environments, log push summaries, and global internet traffic insights.

Where to use

These MCP servers can be utilized across various Cloudflare services in applications involving application development, security monitoring, performance optimization, and analytics. They are particularly useful in environments requiring collaboration between AI tools and cloud infrastructure, allowing users to leverage natural language for task management within their Cloudflare accounts.

Cloudflare MCP Server

Model Context Protocol (MCP) is a new, standardized protocol for managing context between large language models (LLMs) and external systems. In this repository, you can find several MCP servers allowing you to connect to Cloudflare’s service from an MCP client (e.g. Cursor, Claude) and use natural language to accomplish tasks through your Cloudflare account.

These MCP servers allow your MCP Client to read configurations from your account, process information, make suggestions based on data, and even make those suggested changes for you. All of these actions can happen across Cloudflare’s many services including application development, security and performance.

The following servers are included in this repository:

Access the remote MCP server from any MCP client

If your MCP client has first class support for remote MCP servers, the client will provide a way to accept the server URL directly within its interface (e.g. Cloudflare AI Playground)

If your client does not yet support remote MCP servers, you will need to set up its resepective configuration file using mcp-remote (https://www.npmjs.com/package/mcp-remote) to specify which servers your client can access.

Using Cloudflare’s MCP servers from the OpenAI Responses API

To use one of Cloudflare’s MCP servers with OpenAI’s 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.

For example, to use the Browser Rendering MCP server with OpenAI, create an API token in the Cloudflare dashboard here, with the following permissions:

Troubleshooting

"Claude’s response was interrupted … "

If you see this message, Claude likely hit its context-length limit and stopped mid-reply. This happens most often on servers that trigger many chained tool calls such as the observability server.

To reduce the chance of running in to this issue:

• Try to be specific, keep your queries concise.
• If a single request calls multiple tools, try to to break it into several smaller tool calls to keep the responses short.

Paid Features

Some features may require a paid Cloudflare Workers plan. Ensure your Cloudflare account has the necessary subscription level for the features you intend to use.
