Implementation Reference

• src/tools/api-discovery.ts:44-61 (registration)

  Registration of the 'extract_api_schema' tool in the apiDiscoveryTools array, including name, description, and input schema definition.
  { name: 'extract_api_schema', description: 'Extract API schema from discovered endpoints', inputSchema: { type: 'object', properties: { url: { type: 'string', description: 'URL to analyze', }, endpoint: { type: 'string', description: 'Specific endpoint to extract schema from', }, }, required: ['url'], }, },
• src/tools/api-discovery.ts:47-60 (schema)

  Input schema definition for the 'extract_api_schema' tool.
  inputSchema: { type: 'object', properties: { url: { type: 'string', description: 'URL to analyze', }, endpoint: { type: 'string', description: 'Specific endpoint to extract schema from', }, }, required: ['url'], },
• src/tools/api-discovery.ts:188-193 (handler)

  Handler logic in handleAPIDiscoveryTool function that processes the tool call by extracting URL/endpoint params and delegating to APIScraper.extractAPISchema.
  case 'extract_api_schema': { const url = params.url as string; const endpoint = params.endpoint as string | undefined; const schema = await apiScraper.extractAPISchema(url, endpoint); return schema; }
• src/scrapers/api-scraper.ts:180-194 (helper)

  Core implementation of API schema extraction in APIScraper class, which discovers endpoints and constructs a schema object.
  async extractAPISchema(url: string, _endpoint?: string): Promise<Record<string, unknown>> { // This is a simplified version. In production, would analyze actual API responses const result = await this.discoverAPIEndpoints(url); const schema: Record<string, unknown> = { baseUrl: result.baseUrl, endpoints: result.endpoints.map((e) => ({ method: e.method, path: e.path, parameters: e.parameters, })), }; return schema; }
