Returns a Protocol Shell. Can return a specific pre-defined template or a blank shell.

    intent: (Optional) The intent if creating a custom shell.

Implementation Reference

• src/context_engineering_mcp/server.py:246-266 (handler)

  The handler function decorated with @mcp.tool(), implementing the core logic: validates input with ProtocolShellInput, fetches predefined protocol template or generates a generic shell using format_protocol_shell.

  @mcp.tool()
  def get_protocol_shell(name: str = "MyProtocol", intent: str | None = None) -> str:

• src/context_engineering_mcp/server.py:42-45 (schema)

  Pydantic input schema used for validating the tool's parameters: name and optional intent.

  class ProtocolShellInput(BaseModel):
      name: str = Field("MyProtocol", min_length=1, description="Protocol name.")
      intent: str | None = Field(None, description="Optional intent.")
