Implementation Reference

• src/hyperspell_mcp/server.py:99-103 (handler)

  The handler function for the 'List Collections' tool, which fetches and returns the list of collections from the Hyperspell API using the Collection model.
  @mcp.tool_or_resource("collection://", name="List Collections") def list_collections() -> list[Collection]: """Get a list of all collections on Hyperspell""" r = mcp.api.collections.list() return Collection.from_pydantic(r.items)
• src/hyperspell_mcp/types.py:31-35 (schema)

  The Collection dataclass schema used for the output of the 'List Collections' tool, with from_pydantic conversion.
  @dataclass class Collection(BaseModel): name: str documents_count: int = 0
• src/hyperspell_mcp/server.py:99-99 (registration)

  Decorator registering the tool with name 'List Collections' and URI 'collection://', which conditionally adds it as tool or resource.
  @mcp.tool_or_resource("collection://", name="List Collections")
• src/hyperspell_mcp/types.py:17-29 (helper)

  The from_pydantic classmethod used by Collection to convert API responses to the dataclass format.
  @classmethod def from_pydantic( cls, model: PydanticBaseModel | Sequence[PydanticBaseModel] ) -> Self | list[Self]: """Convert a Pydantic model to a data class, selecting only the keys that are part of the data class.""" if isinstance(model, Sequence): return [cls.from_pydantic(m) for m in model] data = model.model_dump() # Only select the keys in data that are part of this data class data = {key: value for key, value in data.items() if key in cls.__annotations__} return cls(**data)
