Implementation Reference

• src/siigo-client.ts:100-101 (handler)

  Core handler function in SiigoClient that performs the authenticated GET request to the Siigo /v1/invoices API endpoint.
  async getInvoices(params?: { page?: number; page_size?: number; created_start?: string; created_end?: string }): Promise<SiigoApiResponse<SiigoInvoice>> { return this.makeRequest<SiigoInvoice>('GET', '/v1/invoices', undefined, params);
• src/index.ts:890-899 (handler)

  MCP server wrapper handler that calls SiigoClient.getInvoices and returns formatted JSON response.
  private async handleGetInvoices(args: any) { const result = await this.siigoClient.getInvoices(args); return { content: [ { type: 'text', text: JSON.stringify(result, null, 2), }, ], };
• src/index.ts:350-362 (registration)

  Tool registration in getTools() method, defining name, description, and input schema.
  { name: 'siigo_get_invoices', description: 'Get list of invoices from Siigo', inputSchema: { type: 'object', properties: { page: { type: 'number', description: 'Page number' }, page_size: { type: 'number', description: 'Number of items per page' }, created_start: { type: 'string', description: 'Start date filter (YYYY-MM-DD)' }, created_end: { type: 'string', description: 'End date filter (YYYY-MM-DD)' }, }, }, },
• src/types.ts:94-143 (schema)

  TypeScript interface defining the structure of a Siigo invoice (output schema).
  export interface SiigoInvoice { id?: string; document: { id: number; number?: number; }; date: string; customer: { person_type?: string; id_type?: string; identification: string; branch_office?: number; name?: string[]; address?: any; phones?: any[]; contacts?: any[]; }; cost_center?: number; currency?: { code: string; exchange_rate: number; }; seller: number; observations?: string; items: Array<{ code: string; description?: string; quantity: number; price: number; discount?: number; taxes?: Array<{ id: number }>; }>; payments: Array<{ id: number; value: number; due_date?: string; }>; stamp?: { send: boolean; }; mail?: { send: boolean; }; global_discounts?: Array<{ id: number; percentage?: number; value?: number; }>; additional_fields?: any; }
• src/siigo-client.ts:41-59 (helper)

  Helper method that handles authentication, makes the Axios HTTP request, and processes responses/errors for all API calls.
  private async makeRequest<T>(method: string, endpoint: string, data?: any, params?: any): Promise<SiigoApiResponse<T>> { await this.authenticate(); try { const response: AxiosResponse<SiigoApiResponse<T>> = await this.httpClient.request({ method, url: endpoint, data, params, }); return response.data; } catch (error: any) { if (error.response?.data) { return error.response.data; } throw new Error(`API request failed: ${error.message}`); } }
