# Compound — canonical payload contracts

Central hatóanyag / active-ingredient master (compound_id). Resolve names, lookup cards, list herbal plants containing a compound. Not medical advice. No live external chemistry APIs.

**Service id:** `compound`  
**Docs:** [https://mcp.glc-rag.hu/guide/compound](https://mcp.glc-rag.hu/guide/compound)  
**Markdown docs:** [https://mcp.glc-rag.hu/guide/compound.md](https://mcp.glc-rag.hu/guide/compound.md)  
**MCP resource:** `docs://compound/payload`

POST `https://mcp.glc-rag.hu/mcp`. Values below are **type slots** from the live input schema (e.g. `<string, required>`), not example data. Fill them from the user task.

RPC result wrapper: `result.structuredContent` is the object in **Output schema**. `result.isError` mirrors `structuredContent.is_error`.
