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 LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
