About MCP
MCP (Model Context Protocol) is the open “AI plugins” standard that went viral across Cursor, Claude, ChatGPT-class apps, and Grok-style assistants. This hub lists open-source MCP servers, clients, and gateways you can inspect—unlike closed plugin marketplaces.

Frequently asked questions about MCP alternatives
What are the best open-source MCP servers?
Browse Awesome [MCP Servers](/projects/awesome-mcp-servers), then verify each repo. Popular categories: filesystem, git, browsers, databases, and docs search. Prefer maintained projects with clear permissions.
What MCP clients can I use?
Goose, Continue, Open WebUI, and other agent/IDE shells increasingly speak MCP or equivalent tool protocols. Match the client to chat vs IDE vs autonomous agents.
Is MCP safer than GPT/Grok plugins?
Open source makes review possible, but power tools are still dangerous. Allowlist servers and assume any shell/file server can damage a machine if misconfigured.
Browse and filter the catalog
Narrow the same alternatives by search, license, tags, or self-hosting signals when you need a tighter shortlist.
