Implementation Reference
- src/tools/index.ts:463-474 (handler)The handler logic within handleToolCall that executes the 'get_contacts_by_list' tool. It calls the SendGrid service method with the provided list_id and returns a formatted JSON string of the contacts (email, first_name, last_name).
case 'get_contacts_by_list': const contacts = await service.getContactsByList(args.list_id); return { content: [{ type: 'text', text: JSON.stringify(contacts.map(c => ({ email: c.email, first_name: c.first_name, last_name: c.last_name })), null, 2) }] }; - src/tools/index.ts:253-266 (schema)Input schema and tool definition (registration) for 'get_contacts_by_list', requiring a 'list_id' string parameter.
{ name: 'get_contacts_by_list', description: 'Get all contacts in a SendGrid list', inputSchema: { type: 'object', properties: { list_id: { type: 'string', description: 'ID of the contact list' } }, required: ['list_id'] } }, - src/services/sendgrid.ts:75-84 (helper)Core helper method in SendGridService that queries the SendGrid Marketing Contacts Search API to retrieve all contacts belonging to the specified list using a CONTAINS query on list_ids.
async getContactsByList(listId: string): Promise<SendGridContact[]> { const [response] = await this.client.request({ method: 'POST', url: '/v3/marketing/contacts/search', body: { query: `CONTAINS(list_ids, '${listId}')` } }); return (response.body as { result: SendGridContact[] }).result || []; } - src/index.ts:42-46 (registration)MCP server registration for listing tools, which includes 'get_contacts_by_list' via getToolDefinitions.
server.setRequestHandler(ListToolsRequestSchema, async () => { return { tools: getToolDefinitions(sendGridService) }; }); - src/index.ts:52-55 (registration)MCP server handler for tool calls, delegating to handleToolCall which processes 'get_contacts_by_list'.
server.setRequestHandler(CallToolRequestSchema, async (request) => { try { return await handleToolCall(sendGridService, request.params.name, request.params.arguments); } catch (error: any) {
