Question 1

What is an MCP server?

Accepted Answer

An MCP server (Model Context Protocol server) is a small program that gives AI assistants like Claude access to external tools and data sources — such as databases, APIs, file systems, and web services. MCP is an open standard created by Anthropic that lets AI models interact with the outside world in a controlled, structured way.

Question 2

How do I install an MCP server?

Accepted Answer

Most MCP servers are installed with a single terminal command (usually starting with npx or pip). After installing, you add a short JSON entry to your Claude Desktop config file (claude_desktop_config.json) and restart the app. Each server page on MCPCMD includes the exact install command and config snippet you need.

Question 3

Are MCP servers safe to use?

Accepted Answer

MCP servers run locally on your machine and only have the permissions you grant them. Official and community-reviewed servers listed on MCPCMD are sourced from public GitHub repositories so you can inspect the code before installing. Always review a server's permissions and source before running it.

Question 4

Which AI assistants support MCP?

Accepted Answer

Claude (via Claude Desktop and the Claude API) has native MCP support. The protocol is also supported by Cursor, Cline, Zed, and other developer tools. Because MCP is an open standard, more AI clients are adding support regularly.

Question 5

What is the difference between a remote and a local MCP server?

Accepted Answer

A local MCP server runs on your own machine — your data never leaves your environment. A remote MCP server is hosted on an external service and connected to over the internet, which means no local installation but requires trusting the host with your data.

Question 6

How do I submit my own MCP server to the directory?

Accepted Answer

Use the Submit MCP page on MCPCMD. Fill in your server's name, description, GitHub URL, install command, and category. Submissions are reviewed by the MCPCMD team and listed once approved — usually within a few days.
