What is MCP.so?

MCP.so is a browsable directory for the Model Context Protocol ecosystem, the open standard that lets AI apps such as Claude, ChatGPT and Cursor call external tools and data. The site gathers MCP servers, remote servers, clients, CLI tools, agent skills, agents and loops in one place, with a search box, category browsing, rankings and a feed of new listings. Featured sections highlight selected servers, and each card shows the author, a short description and, where available, a popularity count. Anyone can submit a listing, and the team publishes guides and articles, including a breakdown of what running MCP servers really costs. Developers and AI users visit it to find an existing connector before writing their own. Browsing is free, and the only published prices are monthly sponsor tiers of $699 and $1,299 for companies that want to advertise on the site.
