What is an MCP Server?

A plain-English explanation of the Model Context Protocol and why it matters for AI agents.

The short version

MCP (Model Context Protocol) is an open standard that lets AI agents connect to external tools and data sources in a consistent way. Instead of every agent needing custom code to talk to every tool, a tool exposes an MCP server once, and any MCP-compatible agent (Claude, Cursor, and others) can use it.

Why it matters

  • Agents get a predictable way to discover what actions a tool supports.
  • Vendors write the integration once instead of maintaining per-agent plugins.
  • Users get more reliable, less hallucination-prone tool use.

Official vs. community servers

An MCP server can be built by the tool vendor (official) or by a third party (community). Official servers tend to be better maintained and more trustworthy, but community servers often fill gaps before a vendor ships their own.

How to find one

Search "[tool] mcp", check the vendor's docs or GitHub org, or browse our directory of MCP servers, which tracks official status, supported actions, and agent-readiness scores for each tool.
