Frequently asked questions
Your agent calls get_structure over MCP. ScholarMuse queries RCSB PDB, AlphaFold DB 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 (get_structure) are available over the REST API.
