Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

interaction
check_interaction
Check the interaction between two drugs (by brand or generic name). Returns severity (contraindicated / major / moderate / minor / unknown), mechanism (when known), and source citations. Always include the response disclaimer in your final answer.
interactions
check_interactions_multi
Pairwise interaction check across a list of drugs (polypharmacy). Returns one entry per unordered pair (dedupes A-B/B-A). Limit 8 drugs (= 28 pairs).
normalize
normalize_drug_name

Drug Interaction Checker — questions

Answers built from our own checks of this server.

What can Drug Interaction Checker do?
It exposes 3 tools, read directly from the server on our last check. Among them: check_interaction, check_interactions_multi, normalize_drug_name. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Drug Interaction Checker working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 6 of 91 checks got a reply (6.6%), average response time 226 ms. The bar chart above shows every period we have measured.
The registry lists Drug Interaction Checker as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Drug Interaction Checker?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Drug Interaction Checker need an API key?
No. Drug Interaction Checker completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Drug Interaction Checker?
It answers our handshake in 226 ms on average, which is faster than 57% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Drug Interaction Checker open source?
Yes — it is published under the NOASSERTION licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
