What is MCP, and how do I use it?
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 its training data.
Each server in the catalogue exposes one data source as a set of tools. Connect an MCP client to a server's endpoint, and the assistant decides when a tool is needed.
How to use these servers
- Pick a server in the catalogue and copy its endpoint, for example
https://allemannsdata.com/weather/mcp. - Add it as a remote server in your MCP client's settings.
- Ask the assistant a question that needs the data. It calls the appropriate tool automatically.
Quick-start example
Most MCP clients accept a JSON configuration shaped like this:
{
"mcpServers": {
"weather": {
"type": "http",
"url": "https://allemannsdata.com/weather/mcp"
}
}
