A side-by-side look at the Medical Codes MCP Server and Mhra Alerts MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Medical Codes MCP Server for biology & bioinformatics work as a local process; choose Mhra Alerts for biology & bioinformatics as a local process. You can also run both side by side in one mcpServers block.
medcode_get_code, medcode_search_codes, medcode_check_code.Rows where the two servers differ are marked.

medcode_get_codeDecode 1–50 codes to their official descriptions. Auto-detects the system per code; partial-success `found` / `notFound`.medcode_search_codesFull-text search over official descriptions — go from a clinical description to the code.medcode_check_codeValidate a code's existence, currency, and billability, with a `whyNot` for non-billable/terminated cases.medcode_map_codesCrosswalk a code within its hierarchy (`parents`/`children`), a drug across RxNorm (name ↔ RXCUI, NDC ↔ RXCUI, RXCUI → ingredients/brands), or a drug to its RxClass classes and a class to its member drugs.medcode_browse_hierarchyWalk a system's hierarchy for discovery without a search term.medcode_list_systemsList bundled systems with release identifiers, effective dates, and code counts, and the RxClass layer with each source's version (provenance).No tool names declared yet. Check the project README from the listing page.
Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
