Model Context Protocol (MCP)
Also called MCP, MCP server
The Model Context Protocol is an open standard for connecting AI assistants to tools and data. A service exposes an MCP server, and any MCP client, such as Claude or Cursor, can call its tools.
An MCP server describes the tools it offers, each with a name, a description and the inputs it accepts. The client shows those tools to the model, the model decides when to call one, and the server does the work and returns the result.
For a product, an MCP server is a second front door. An assistant can do the job through the server without driving the interface, which is faster and less fragile than clicking through the page.
Where Stunt Double fits
