Devin, Replit Agent, and Cursor all converge on MCP-native architecture

The major autonomous coding agents have all shipped MCP-native support within the last 30 days: Devin (Cognition Labs), Replit Agent 3, and Cursor. Claude Code remains the reference implementation.

MCP (Model Context Protocol) was originally Anthropic's tool integration standard. The convergence means an MCP server written once works across all four major agent products — a meaningful win for the ecosystem and a competitive moat for whoever owns the most-used MCP servers.

Devin enterprise pricing starts at $500/month per seat. Replit Agent 3 is bundled at $20/month plus usage. Cursor remains the most popular by user count, with revenue doubling in 90 days.
