"""MCP (Model Context Protocol) client support for pydantic-deep.

Declarative server configs (:class:`MCPServerConfig` / :class:`MCPAuth`), a
secret-aware :class:`MCPRegistry` that builds connected pydantic-ai toolsets,
curated built-in servers, and a connection probe. The optional ``mcp`` extra
provides the underlying transport (``pip install 'pydantic-deep[mcp]'``).
