What is the NLM RxNorm (Drug Database) MCP Server?
Connect your AI agent to the National Library of Medicine (NLM) RxNorm database. This server provides comprehensive access to standardized drug nomenclature and relationships, allowing for precise identification and analysis of pharmaceutical products.
What you can do
- Drug Search — Find RxNorm Concept Unique Identifiers (RxCUIs) by name, identifier (NDC, ATC, SNOMEDCT), or approximate matching using
find_rxcui_by_stringandfind_rxcui_by_id. - Property Inspection — Retrieve detailed drug properties, including names, synonyms, and attributes categorized by source via
get_all_properties. - Relationship Mapping — Explore related concepts and term types (TTY) to understand drug hierarchies and ingredients using
get_all_related_info. - Spelling Correction — Get suggestions for misspelled drug names to ensure accurate queries with
get_spelling_suggestions. - NDC & Identifier Lookup — Map external codes to RxNorm standards for interoperability.
How it works
- Subscribe to this server
- Enter your NLM UTS API Key
- Start querying drug data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Healthcare Developers — Integrate standardized drug data into clinical decision support tools.
- Medical Researchers — Analyze drug relationships and properties using a trusted, standardized vocabulary.
- Data Scientists — Map disparate drug datasets to a common RxNorm standard for analysis.

Frequently asked questions
How can I find the RxCUI for a specific drug name?
You can use the find_rxcui_by_string tool. Simply provide the drug name, and the agent will return the associated RxNorm Concept Unique Identifiers.
What should I do if I am unsure of the correct spelling of a drug?
Use the get_spelling_suggestions tool. It provides strings similar to your input to help you find the correct standardized drug name.
Can I retrieve all properties, such as synonyms and attributes, for a drug?
Yes, the get_all_properties tool allows you to fetch detailed attributes, codes, and names associated with a specific RxCUI.
How does Claude Desktop discover MCP tools?
When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.
What happens if the MCP server is temporarily unavailable?
Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.
Can I connect multiple MCP servers simultaneously?
Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.
Is there a limit on the number of tools per server?
Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.
Does Claude Desktop support Streamable HTTP transport?
Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
