Implementation Reference

• mcp_server/flexsim_mcp.py:438-461 (handler)

  The main handler function flexsim_save_model that executes the save model logic. It accepts an optional save_path parameter, uses the FlexSim controller to evaluate the savemodel() FlexScript command, and returns a success message indicating where the model was saved.

  @mcp.tool()
  async def flexsim_save_model(params: SaveModelInput) -> str:
      """Save the current model.
  
      Args:
          save_path: Path to save (optional, uses current if not provided)
  
      Example:
          save_path="C:/Models/warehouse_v2.fsm"
      """
      try:
          controller = await get_controller()
  
          if params.save_path:
              script = f'savemodel("{params.save_path}")'
              location = params.save_path
          else:
              script = "savemodel()"
              location = "current location"
  
          controller.evaluate(script)
          return f"✓ Model saved to {location}"
      except Exception as e:
          return format_error(e)

• mcp_server/flexsim_mcp.py:99-101 (schema)

  The SaveModelInput schema class that defines the input validation for the flexsim_save_model tool. It uses Pydantic BaseModel with an optional save_path string field that defaults to None.

  class SaveModelInput(BaseModel):
      """Input for saving model."""
      save_path: str | None = Field(default=None)

• mcp_server/flexsim_mcp.py:438-438 (registration)

  The @mcp.tool() decorator that registers the flexsim_save_model function as an MCP tool, making it available to clients through the Model Context Protocol server.
