Appendix MCP Server
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.
