Cinema4D MCP Server

Instructions

Create and apply a specialized shader material.

Args:
    shader_type: Type of shader (noise, gradient, fresnel, etc)
    material_name: Optional name of material to apply shader to
    object_name: Optional name of object to apply the material to

Implementation Reference

• src/cinema4d_mcp/server.py:970-997 (handler)

  The handler function `apply_shader` executes the shader application logic by sending a command to the Cinema 4D connection.

  async def apply_shader(
      shader_type: str,
      material_name: Optional[str] = None,
      object_name: Optional[str] = None,
      ctx: Context = None,
  ) -> str:
