MCP Server Configuration for Surf Spot Finder.
This module implements the Model Context Protocol server that exposes
surf spot data as MCP resources. It provides the core resource handlers
for listing and reading surf spot information.
The server exposes:
- surf://spots/database: 22 world-class surf spots with metadata
Example:
>>> resources = await list_resources()
>>> content = await read_resource("surf://spots/database")
>>> spots = json.loads(content)["spots"]
