MCP Servers

Jotsu hosts several multi-tenant, open-source MCP servers that are freely available for public use. The source code for each server is provided and serve as reference implementations of streamable-http services.

Each server has its own documentation for authentication and deployment details-refer to the individual repositories for specifics. You can use these servers as practical examples for building your own MCP-compatible tools, including support for custom authentication mechanisms such as OAuth2.

Servers​

Available servers:

  • discord A MCP server that can send messages to an authorized Discord server. It uses a Discord Bot token for authorization.

  • weather The NWS Weather MCP server from the modelcontextprotocol.io adapted for deployment on Cloudflare. NOTE: This server relies on the NWS API and may hit rate limits.

  • mailgun Send emails using Mailgun.

Development servers​

The remaining servers are useful as a reference for developing your own servers.

  • hello Basic, starting-point MCP server that provides a single tool and a couple of resources. This is a good starting point if you are trying to build your own.

  • oauth2 An MCP server with full OAuth2 support that uses Discord as a pass-through auth server. This server aims to provide a simple example of how to add OAuth2 support to an MCP Server. It uses an implementation OAuthAuthorizationServerProvider from jotsu-mcp to provide full OAuth2.1 suppot.

Why Use These Servers?​

Many services and platforms provide MCP server implementations—but the majority are designed for stdio communication, making them suitable only for local or embedded use. These implementations typically lack critical features like network authentication, because they were never intended to run as remote services.

Jotsu's MCP servers are built differently. They are designed from the ground up for deployment over the network using streamable-http, making them secure, scalable, and production-ready. Each server includes support for authentication (such as API keys or OAuth2), making them far more suitable for cloud or distributed environments.

If you're building your own MCP server, these implementations provide real-world, working examples of how to integrate authentication and deploy seamlessly on a global edge platform like Cloudflare.
