Implementation Reference
- src/index.ts:1160-1181 (handler)The main handler function that implements the get_safety_data tool. Validates input CID, fetches classification/safety data from PubChem API, and returns JSON response.
private async handleGetSafetyData(args: any) { if (!isValidCidArgs(args)) { throw new McpError(ErrorCode.InvalidParams, 'Invalid CID arguments'); } try { const response = await this.apiClient.get(`/compound/cid/${args.cid}/classification/JSON`); return { content: [ { type: 'text', text: JSON.stringify(response.data, null, 2), }, ], }; } catch (error) { throw new McpError( ErrorCode.InternalError, `Failed to get safety data: ${error instanceof Error ? error.message : 'Unknown error'}` ); } } - src/index.ts:639-649 (registration)Tool registration entry in the ListToolsRequestSchema handler, defining the tool name, description, and input schema requiring a CID.
{ name: 'get_safety_data', description: 'Get GHS hazard classifications and safety information', inputSchema: { type: 'object', properties: { cid: { type: ['number', 'string'], description: 'PubChem Compound ID (CID)' }, }, required: ['cid'], }, }, - src/index.ts:792-793 (registration)Dispatch case in the CallToolRequestSchema handler that routes get_safety_data calls to the specific handler method.
case 'get_safety_data': return await this.handleGetSafetyData(args); - src/index.ts:65-74 (helper)Helper validation function used by get_safety_data handler to validate input arguments, specifically checking for valid CID.
const isValidCidArgs = ( args: any ): args is { cid: number | string; format?: string } => { return ( typeof args === 'object' && args !== null && (typeof args.cid === 'number' || typeof args.cid === 'string') && (args.format === undefined || ['json', 'sdf', 'xml', 'asnt', 'asnb'].includes(args.format)) ); };
