Implementation Reference
- src/index.ts:954-956 (handler)The handler function that implements the core logic of the 'search_by_cas_number' tool. Currently a placeholder that returns a 'not yet implemented' message with input args.private async handleSearchByCasNumber(args: any) { return { content: [{ type: 'text', text: JSON.stringify({ message: 'CAS search not yet implemented', args }, null, 2) }] }; }
- src/index.ts:420-426 (schema)Input schema defining the expected parameters for the 'search_by_cas_number' tool: a required 'cas_number' string.inputSchema: { type: 'object', properties: { cas_number: { type: 'string', description: 'CAS Registry Number (e.g., 50-78-2)' }, }, required: ['cas_number'], },
- src/index.ts:417-427 (registration)Registration of the 'search_by_cas_number' tool in the ListTools response, including name, description, and schema.{ name: 'search_by_cas_number', description: 'Search for compounds by CAS Registry Number', inputSchema: { type: 'object', properties: { cas_number: { type: 'string', description: 'CAS Registry Number (e.g., 50-78-2)' }, }, required: ['cas_number'], }, },
- src/index.ts:748-749 (registration)Dispatch case in the CallToolRequest handler that routes calls to the search_by_cas_number handler function.case 'search_by_cas_number': return await this.handleSearchByCasNumber(args);
