Agent Ready: 7/7

A deep dive into MCP (Model Context Protocol) servers — the open standard connecting AI agents to tools, data, and services. How MCP works, the ecosystem landscape, and how to evaluate server quality for AI agent integration.

Top Benefits

  • Open standard — MCP is not controlled by any single company (initiated by Anthropic but open to all). This prevents vendor lock-in and encourages a broad ecosystem of servers, clients, and tools.
  • Fast-growing ecosystem — over 1,000 MCP servers available as of mid-2026, covering databases, APIs, developer tools, file systems, web scraping, and more. The growth rate is exponential, with dozens of new servers added weekly.
  • Native client adoption — Claude Desktop, Claude Code, and Cursor ship with MCP support built in. This means every user of these tools can immediately connect to MCP servers without additional configuration or plugins.
