Frequently asked questions

Your agent calls lookup_drug over MCP. ScholarMuse queries ChEMBL, openFDA and returns records, each with its source, licence and a link you can check.

No. It costs 1 credit per call, charged only when the call succeeds. A new account gets 50 credits once, valid for 30 days.

Claude, ChatGPT, Codex, Cursor, Gemini CLI and any other client that supports MCP.

Yes. The same tools (lookup_drug) are available over the REST API.
