NetSendo v1.7.7: Smarter AI Agents with Enhanced MCP

The future of marketing automation isn't just about scheduling emails; it's about creating intelligent systems that can react, create, and personalize on their own. What if your AI agent could instantly know every personalization option available and build a hyper-targeted campaign from a simple instruction? With NetSendo v1.7.7, this is now a reality.

This release is laser-focused on enhancing our Marketing Control Protocol (MCP), the powerful API layer that allows developers and AI agents to programmatically control NetSendo. We're giving you—and your AI—the tools for smarter, context-aware automation.

🚀 What's New: A Smarter MCP for AI Agents

Version 1.7.7 transforms the developer experience for anyone building on top of NetSendo. We've bridged the gap between your AI's intent and its ability to execute complex marketing tasks.

The 'list_placeholders' Tool: Giving AI Full Visibility

Previously, an AI agent had to guess or be hard-coded with the available placeholders (like [[fname]] or custom fields). Now, it can simply ask. The new list_placeholders tool provides a complete list of system, custom, and special placeholders.

Think of it as giving your AI a "cheat sheet" of every personalization token in your NetSendo instance. This allows it to dynamically craft messages using the exact data points you've collected about your subscribers.

// Example using @netsendo/mcp-client
import { MCPClient } from '@netsendo/mcp-client';

const client = new MCPClient('your-mcp-server-url', 'your-api-key');

async function getPlaceholders() {
  const placeholders = await client.listPlaceholders();
  console.log(placeholders);
  // Output: ['[[fname]]', '[[lname]]', '[[email]]', '[[!fname]]', '[[unsubscribe_link]]', ...]
}

Revamped MCP Marketplace UI for Faster Integration

To support these new API capabilities, we've overhauled the MCP Marketplace in the NetSendo dashboard. You'll now find a dedicated section with comprehensive documentation on all available placeholders and a new "Technical Prompt" area. This prompt provides a perfectly formatted block of text you can copy and paste directly into your AI agent's configuration (e.g., in frameworks like crewAI or AutoGPT), telling it exactly what tools it has at its disposal.

ℹ️ Note: We've also added full Polish (PL) and English (EN) translations for all new MCP sections, making it accessible to more users.

💡 Benefits & Use Cases

These enhancements unlock a new level of sophistication for your automated marketing. As a self-hosted platform, NetSendo gives you the freedom to build these powerful systems with no limits on sending and full data ownership.
