## 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).
MCP readiness
Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here C+, 70.0/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ
| Valid MCP handshake | 10/10 | initialize and tools/list both answered. |
| Live MCP endpoint | 24/25 | Endpoint answers the MCP initialize handshake (4755 ms); slow response -1. |
| Protocol revision | 8/10 | Speaks MCP 2025-11-25, 1 revision(s) behind 2026-07-28. |
| Signed descriptor | n/a | No MCP standard defines a signed server descriptor. |
| Uptime (30 days) | 15/15 | 30/30 probes succeeded over 30 days (100%). |
| Tool declaration | 10/10 | Lists 3 tool(s) with descriptions. |
| Verified identity | 5/10 | Publisher declared (repository, package or homepage); claim this listing to verify domain control. |
| Freshness + modern flags | 4/5 | seen in a source within 7 days. |
| Auth declaration | 2/5 | Declares credential scheme: smithery_api_key. |
