Install Appendix MCP Server

The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.

  • Claude Code

    claude mcp add --transport http --scope user appendix-mcp-server 'https://mcp.appendix.com/mcp'

    Run it once in your project, then open /mcp to approve any sign-in the server asks for.

  • Claude Desktop

    https://mcp.appendix.com/mcp

    Add a custom connector in Settings, paste this address, and approve the sign-in.

  • Cursor

    cursor://anysphere.cursor-deeplink/mcp/install?name=appendix-mcp-server&config=eyJ1cmwiOiJodHRwczovL21jcC5hcHBlbmRpeC5jb20vbWNwIn0=

    Open the link and Cursor adds the server at that address.

  • ChatGPT

    https://mcp.appendix.com/mcp

    In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.

  • Codex

    codex mcp add appendix-mcp-server --url 'https://mcp.appendix.com/mcp'

    Run it once, then sign in with codex mcp login appendix-mcp-server if the server asks for an account.

From the project's README

As published by appendixhealth/mcp-server in README.md.

Appendix turns any AI health conversation into a physician-reviewed opinion, with a prescription if you need one.

Your agent writes a medical encounter summary, submits it through our API, and a real doctor signs off.

Use the Appendix MCP server to search medical literature, submit clinical encounters, and receive clinical guidance and prescriptions from board-certified physicians. Learn more at appendix.com.
