MCP (Model Context Protocol) is an open standard that lets an AI assistant fetch live data or take actions during a conversation, instead of relying only on what it learned during training.
Each server on the front page is one such data source, exposed as a set of "tools" (for example get today's weather, or look up a company). You never call these tools yourself — you connect an MCP client to a server's web address (its endpoint), and the assistant decides on its own when a tool is needed to answer your question.
https://allemannsdata.com/weather/mcp.Most MCP clients accept a small JSON config with this shape (this example connects the weather server):
{
"mcpServers": {
"weather": {
"type": "http",
"url": "https://allemannsdata.com/weather/mcp"
}
}
}
See the full documentation for the complete endpoint list, Claude Code CLI setup, and raw .mcp.json config.
