MCPs are APIs for LLMs

Updated: at 06:54 AM

Here’s the simple version:

  • An MCP server exposes a bunch of end points, like any other API server, but it _must_have end points that list all the available functions on a server in a standard way an MCP client can understand.
  • MCP clients (usually LLM-powered), like Anthropic’s Claude Desktop, can then be connected to MCP servers and immediately know what tools are available for them to use.
  • LLMs connected to MCPs can now call MCP servers using the specs provided by the API.
