- src/index.ts:674-699 (handler)The main handler function that validates the input patent_number and retrieves the patent document contents by making an API call to the SureChEMBL endpoint `/document/{patent_number}/contents`. Returns formatted JSON response or throws MCP errors.
private async handleSearchByPatentNumber(args: any) { if (!args || typeof args.patent_number !== 'string') { throw new McpError(ErrorCode.InvalidParams, 'Invalid patent number'); } try { // Try to get document content directly const response = await this.apiClient.get(`/document/${args.patent_number}/contents`); return { content: [ { type: 'text', text: JSON.stringify({ patent_number: args.patent_number, document: response.data }, null, 2), }, ], }; } catch (error) { throw new McpError( ErrorCode.InternalError, `Failed to find patent: ${error instanceof Error ? error.message : 'Unknown error'}` ); } } - src/index.ts:375-385 (registration)Registers the 'search_by_patent_number' tool with the MCP server, providing the tool name, description, and input schema for validation.
