Line of Succession

This is the MCP endpoint for Line of Succession. MCP clients should send JSON-RPC POST requests to:

Return the British sovereign on a given date.

Looks up the reigning British sovereign for the supplied date.

Use this when answering questions such as “Who was sovereign on 6 February 1952?”

{ "properties" : { "date" : { "type" : "string", "description" : "Date in YYYY-MM-DD format." } }, "type" : "object", "required" : [ "date" ] }

Return the line of succession on a given date.

If no date is supplied, the current line of succession is returned.

Omit for the current line of succession.", "type" : "string" } } }

Choose a date from the date-picker above or from the "interesting dates" menu to see the line of succession to the British throne on that date.
