This repository is a curated catalog of Hosted MCP servers. Each entry points to an external MCP endpoint you can connect to from your MCP client or integration. To start using, pick a server from the Hosted MCP Server List and copy its URL. In your MCP client (e.g., Claude, ChatGPT, Agentic Workers, or any MCP-capable client), configure the MCP connection by supplying the server URL as the MCP endpoint and select the appropriate authentication method listed for that server (OAuth 2.1, Open, or API Key). Since these are hosted endpoints, you do not run a local MCP server; you simply point your client at the provided URL and follow the on-screen flow to authenticate if required. The page also explains the different authentication options you may encounter and how they influence how you connect to a given hosted server. Tools and capabilities described here emphasize secure, production-ready MCP endpoints that you can integrate into your AI workflows without npm installs or local server setup.

Prerequisites:

• A client that supports MCP endpoints (e.g., Claude, ChatGPT, Agentic Workers, Cursor, or a custom MCP client).
• Internet access to reach hosted MCP URLs.
• Awareness of the authentication method used by the target hosted MCP server (OAuth 2.1, OAuth 2.1 with limited scope, API Key, or Open access).

Steps:

1. Review the Hosted MCP Server List and choose a server that fits your use case.
2. Copy the server URL and the required auth method from the table in the README.
3. In your MCP client, configure a new MCP connection using the server URL and the appropriate authentication flow (e.g., OAuth 2.1 or API Key).
4. Authenticate as required and start sending MCP requests to the server endpoint.
5. If your client supports dynamic discovery, you may be guided through the server’s capabilities and available MCP context tooling once connected.

Notes:

• No local server installation is needed for hosted MCP servers.
• Some servers require pre-approval or API keys; ensure you have access before attempting to connect.

Tips and common issues:

• OAuth 2.1 endpoints may require you to complete a consent flow in a browser; ensure your client can handle the redirect URI.
• Some entries are labeled with OAuth2.1 🔐 to indicate some constraints around client registration; you may need a pre-registered client or API key.
• If you encounter connectivity issues, verify the server URL is correct and that there are no corporate firewall blocks to the endpoint.
• The list emphasizes official, production-ready servers; for production use, prioritize servers with active maintenance and clear security measures (OAuth 2.0/APIs).
• Open access servers are easiest to try but less secure; use them only for experimentation or non-sensitive data flows.
• This catalog is a reference; always refer to the provider’s documentation for exact authentication steps and rate limits.
