Common questions

Is MCP Terminology safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 5 months ago, and the latest version (1.0.0) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

mcp-terminology

Unified LOINC / SNOMED CT / RxNorm / ICD-10 MCP server — v1.0.0

Part of the fhir-mcp-suite monorepo.

Query four major clinical terminology systems through a single MCP server backed by the free public FHIR R4 terminology server (tx.fhir.org/r4).

Tools

Tool	Description	Backend operation
`lookup_code`	Look up a single code — returns display, definition, designations	`CodeSystem/$lookup`
`search_codes`	Free-text search within LOINC, SNOMED CT, or RxNorm	`ValueSet/$expand?filter=`
`translate_code`	Translate a code across systems (SNOMED ↔ ICD-10-CM, etc.)	`ConceptMap/$translate`
`expand_valueset`	Expand any canonical FHIR ValueSet by URL	`ValueSet/$expand`

Supported systems for `lookup_code`
