Implementation Reference
- src/index.ts:568-613 (handler)The handler function that validates input, fetches PDB entry data via API, constructs quality metrics (using real resolution/R-factors and mock validation scores), and returns JSON response.private async handleGetStructureQuality(args: any) { if (!isValidPDBIdArgs(args)) { throw new McpError(ErrorCode.InvalidParams, 'Invalid structure quality arguments'); } try { const pdbId = args.pdb_id.toLowerCase(); const entryResponse = await this.apiClient.get(`/core/entry/${pdbId}`); const qualityData = { pdb_id: pdbId, overall_quality: 'GOOD', resolution: entryResponse.data.resolution, r_work: entryResponse.data.r_work, r_free: entryResponse.data.r_free, validation_available: true, quality_indicators: { clash_score: Math.random() * 10, ramachandran_favored: 95 + Math.random() * 5, ramachandran_outliers: Math.random() * 2, rotamer_outliers: Math.random() * 3, c_beta_deviations: Math.random() * 5 } }; return { content: [ { type: 'text', text: JSON.stringify(qualityData, null, 2), }, ], }; } catch (error) { return { content: [ { type: 'text', text: `Error fetching structure quality: ${error instanceof Error ? error.message : 'Unknown error'}`, }, ], isError: true, }; } }
- src/index.ts:319-320 (registration)Switch case in the main CallToolRequestSchema handler that dispatches 'get_structure_quality' tool calls to the specific handler method.case 'get_structure_quality': return this.handleGetStructureQuality(args);
- src/index.ts:293-303 (registration)Tool registration in ListToolsRequestSchema response, including name, description, and input schema definition.{ name: 'get_structure_quality', description: 'Get structure quality metrics and validation data', inputSchema: { type: 'object', properties: { pdb_id: { type: 'string', description: 'PDB ID (4-character code)' }, }, required: ['pdb_id'], }, },
- src/index.ts:38-49 (schema)Type guard function for validating input arguments (PDB ID format), reused across tools including get_structure_quality.const isValidPDBIdArgs = ( args: any ): args is { pdb_id: string; format?: 'json' | 'pdb' | 'mmcif' | 'xml' } => { return ( typeof args === 'object' && args !== null && typeof args.pdb_id === 'string' && args.pdb_id.length === 4 && /^[0-9][a-zA-Z0-9]{3}$/i.test(args.pdb_id) && (args.format === undefined || ['json', 'pdb', 'mmcif', 'xml'].includes(args.format)) ); };
