MCP Servers

The official collection of reference servers and example implementations maintained by the Model Context Protocol project.

An MCP server that connects agents to Chrome DevTools for page debugging, performance analysis, network inspection, and browser automation.

Lets agents navigate websites, read pages, and perform actions through structured browser interaction.

MCP Inspector is the official Model Context Protocol debugging tool. Its Web, CLI, and TUI clients connect to MCP servers and inspect tools, resources, prompts, transports, authentication, and MCP Apps.

A local tool server for desktop MCP clients, exposing file read/write and search, surgical edits, terminal commands, process management, and structured-data analysis over STDIO. Its broad host permissions require narrow directory scope and container or VM isolation for sensitive work.

An MCP server and standalone CLI that give coding agents access to Xcode builds, tests, simulators, devices, debugging, and UI automation.

Callstack's cross-platform app automation toolkit drives mobile, TV, web, and desktop apps through a stdio MCP server, CLI, and typed TypeScript API while collecting screenshots, logs, network, and performance evidence.
