## Purpose

Source: AI-written repository summary; verify against source.

> A collection of reference implementations for the Model Context Protocol (MCP), a framework that enables Large Language Models to securely interact with external tools and data sources.

## Main parts

> Server Implementations: Seven independent MCP server packages, each demonstrating specific capabilities and transport mechanisms.

## Evidence gaps

> RepoPilot has not run the setup commands or tests.
> Files marked “likely” are guessed from their names.
> 1 suggested change pattern has no matching file and is left out.
> Could not capture package-lock.json: source unavailable or larger than the capture limit. Open its source link to check setup.
> The intended package manager and version are not established by captured evidence.
> Runtime versions and other prerequisites were not captured.
> Root development commands were not established. Check the root manifest and contributor guide.
> Setup has not been executed. Environment variables, external services and command order may require additional source documentation.
