appendix

## Appendix Appendix turns any AI health conversation into a board-certified physician's opinion — with a real prescription when clinically appropriate. Your agent searches peer-reviewed medical literature, helps you write a structured clinical letter, and submits it through the Appendix API. A licensed physician personally reviews it and issues a prescription when appropriate, sent to the pharmacy of your choice. The **Knowledge Base is free** and open to everyone. **Clinical services** (physician review + prescriptions) are a paid subscription available in supported US states — and you can start using the API with **no signup required**. ### Install **Claude Code** ```bash claude mcp add --transport http appendix https://mcp.appendix.com/mcp ``` **Claude Desktop / Claude.ai connectors** ```json { "mcpServers": { "appendix": { "url": "https://mcp.appendix.com/mcp" } } } ``` ### Tools | Tool | Description | |------|-------------| | `search_knowledge_base` | Search medical literature and treatment guidelines | | `submit_encounter` | Submit a clinical letter for board-certified physician review | | `list_conditions` | List available conditions and medications | Learn more at [appendix.com](https://appendix.com).
