Implementation Reference
- src/index.ts:599-626 (handler)The handler function that implements the core logic for the 'search_patents' tool. It validates input arguments, performs a chemical name search via the SureChEMBL API as a proxy for patent search, and formats the response.private async handleSearchPatents(args: any) { if (!isValidSearchArgs(args)) { throw new McpError(ErrorCode.InvalidParams, 'Invalid search arguments'); } try { // SureChEMBL doesn't have a direct patent search endpoint, so we'll search chemicals and return patent context const response = await this.apiClient.get(`/chemical/name/${encodeURIComponent(args.query)}`); return { content: [ { type: 'text', text: JSON.stringify({ query: args.query, message: 'Patent search via chemical name lookup', results: response.data }, null, 2), }, ], }; } catch (error) { throw new McpError( ErrorCode.InternalError, `Failed to search patents: ${error instanceof Error ? error.message : 'Unknown error'}` ); } }
- src/index.ts:343-351 (schema)The JSON schema defining the input parameters for the 'search_patents' tool, including query (required), limit, and offset.inputSchema: { type: 'object', properties: { query: { type: 'string', description: 'Search query (keywords, patent numbers, or text)' }, limit: { type: 'number', description: 'Number of results to return (1-1000, default: 25)', minimum: 1, maximum: 1000 }, offset: { type: 'number', description: 'Number of results to skip (default: 0)', minimum: 0 }, }, required: ['query'], },
- src/index.ts:544-545 (registration)The switch case in the CallToolRequestSchema handler that registers and dispatches calls to the 'search_patents' handler function.case 'search_patents': return await this.handleSearchPatents(args);
- src/index.ts:340-352 (registration)The tool registration entry in the ListToolsRequestSchema response, defining name, description, and schema for 'search_patents'.{ name: 'search_patents', description: 'Search patents by text, keywords, or identifiers in SureChEMBL database', inputSchema: { type: 'object', properties: { query: { type: 'string', description: 'Search query (keywords, patent numbers, or text)' }, limit: { type: 'number', description: 'Number of results to return (1-1000, default: 25)', minimum: 1, maximum: 1000 }, offset: { type: 'number', description: 'Number of results to skip (default: 0)', minimum: 0 }, }, required: ['query'], }, },
- src/index.ts:80-91 (helper)Helper function for validating the input arguments specifically for the search_patents tool.const isValidSearchArgs = ( args: any ): args is { query: string; limit?: number; offset?: number } => { return ( typeof args === 'object' && args !== null && typeof args.query === 'string' && args.query.length > 0 && (args.limit === undefined || (typeof args.limit === 'number' && args.limit > 0 && args.limit <= 1000)) && (args.offset === undefined || (typeof args.offset === 'number' && args.offset >= 0)) ); };
