  Model Context Protocol bindings for Python
  
  These bindings were generated from https://github.com/modelcontextprotocol/specification,
  using Claude, with a prompt something like the following:
  
  Generate idiomatic Python bindings for this schema for MCP, or the "Model Context
  Protocol." The schema is defined in TypeScript, but there's also a JSON Schema version
  for reference.
  
  * For the bindings, let's use Pydantic V2 models.
  * Each model should allow extra fields everywhere, by specifying `model_config =
    ConfigDict(extra='allow')`. Do this in every case, instead of a custom base class.
  * Union types should be represented with a Pydantic `RootModel`.
  * Define additional model classes instead of using dictionaries. Do this even if they're
    not separate types in the schema.
