MartechDB vs Zapier MCP
Not either/or. Use a vendor's own server where there is one, and Zapier or Composio for the rest.
This page covers Zapier MCP and Composio.
01
What Zapier MCP is
Zapier MCP lets an AI tool use Zapier's connections to around 9,000 apps and more than 66,000 triggers and actions, through one server Zapier hosts. Zapier manages the app credentials, and each tool call uses two tasks from your Zapier plan. Composio is a similar layer for developers, connecting AI tools to more than 1,500 apps through MCP or an API, with a free tier and usage-based plans. MartechDB is different: it lists the servers that martech vendors publish themselves.
MartechDB lists only the official MCP servers that martech vendors publish themselves: 1,552 vendors and 1,662 servers as of today. The data is free on the web, in a JSON API and through our own MCP server, and vendors can't pay to be listed.
