What is an MCP server?

An MCP server exposes tools, resources and prompts over the Model Context Protocol, an open standard from Anthropic. An agent connects to it and gains whatever the server wraps: your database, GitHub, a browser, an internal API. One server works with every MCP client.

What can I do with an MCP server?

Give an agent access to a system it otherwise cannot reach. Query a production database in plain language, open pull requests, read a Notion workspace, drive a headless browser, or call an internal service. The server decides which operations are exposed and which stay off limits.

Do MCP servers only work with Claude?

No. MCP is an open protocol with clients across the ecosystem: Claude Code and the Claude apps, Cursor, Windsurf, VS Code, Zed, OpenAI's Agents SDK and others. A server written once works in all of them; each listing shows the config snippet per client.

How do I install an MCP server?

Add it to your client's MCP configuration: a command and arguments for a local (stdio) server, or a URL for a remote (HTTP) one. Every listing here carries a ready-made snippet for each major client, plus the credentials that server needs.

MCP servers, explained

An MCP server is a small program that exposes one system, such as a database, an API or a filesystem, to an AI agent through the Model Context Protocol, so any MCP-speaking client can use it without a custom integration. Each server below lists its transport, deployment and the tools it exposes.
