MCP protocol handler setup and wire-format handlers for FastMCP Server.
Classes
MCPOperationsMixin
Mixin providing MCP protocol handler setup and wire-format handlers.
Note: Methods registered with SDK decorators (e.g., _list_tools_mcp, _call_tool_mcp)
cannot use self: FastMCP type hints because the SDK’s get_type_hints() fails
to resolve FastMCP at runtime (it’s only available under TYPE_CHECKING). When
type hints fail to resolve, the SDK falls back to calling handlers with no arguments.
These methods use untyped self to avoid this issue.
