Implementation Reference
- The main handler function that implements the create_buyer tool. It validates credentials, constructs the buyer payload, posts to Finix /identities endpoint, and returns the new identity ID.const createBuyer = async (client: FinixClient, _context: FinixContext, params: any): Promise<any> => { try { if (!client.hasCredentials()) { throw new Error('Finix username and password are required for this operation. Please configure FINIX_USERNAME and FINIX_PASSWORD in your environment.'); } const { email, first_name, last_name, phone } = params; const payload = { entity: { email, first_name, last_name, phone }, type: 'PERSONAL', identity_roles: ['BUYER'] }; const response = await client.post('/identities', payload); if (response.error) { throw new Error(`Error creating buyer: ${response.error.message}`); } // Return just the ID like Stripe MCP return { id: response.data.id }; } catch (error) { throw error; } };
- Zod schema defining the input parameters for the create_buyer tool: email, first_name, last_name, phone.const createBuyerParameters = () => z.object({ email: z.string().email().describe('The email address of the buyer'), first_name: z.string().describe('The first name'), last_name: z.string().describe('The last name'), phone: z.string().describe('The phone number') });
