Combines 4 tools from 4 SCP server(s)." --- # CAS Number Compound Lookup **Discipline**: Chemical Information | **Tools Used**: 4 | **Servers**: 4 ## Description Look up compounds by CAS: convert CAS to price/availability, get PubChem data, get ChEMBL info, and structure analysis. ## Tools Used - **`CASToPrice`** from `server-30` (sse) - `https://scp.intern-ai.org.cn/api/v1/mcp/30/SciToolAgent-Mat` - **`get_compound_by_name`** from `pubchem-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/8/Origene-PubChem` - **`get_molecule_by_name`** from `chembl-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/4/Origene-ChEMBL` - **`ChemicalStructureAnalyzer`** from `server-28` (sse) - `https://scp.intern-ai.org.cn/api/v1/mcp/28/InternAgent` ## Workflow 1. Look up CAS and pricing 2. Get PubChem compound data 3. Get ChEMBL molecule info 4. Analyze chemical structure ## Test Case ### Input ```json { "compound_name": "caffeine" } ``` ### Expected Steps 1. Look up CAS and pricing 2. Get PubChem compound data 3. Get ChEMBL molecule info 4. Analyze chemical structure ## Usage Example > **Note:** Replace `sk-b04409a1-b32b-4511-9aeb-22980abdc05c` with your own SCP Hub API Key.
