Implementation Reference
- The MCP tool handler for 'cancel_prediction' that executes the cancellation logic using the ReplicateClient.async def cancel_prediction(prediction_id: str) -> dict[str, Any]: """Cancel a running prediction.""" async with ReplicateClient(api_token=os.getenv("REPLICATE_API_TOKEN")) as client: response = await client.cancel_prediction(prediction_id) return await response.json()
- Supporting method in ReplicateClient that performs the HTTP POST request to the Replicate API endpoint for canceling a prediction.async def cancel_prediction(self, prediction_id: str) -> dict[str, Any]: """Cancel a running prediction. Args: prediction_id: The ID of the prediction to cancel Returns: Dict containing the updated prediction status Raises: ValueError: If the prediction is not found Exception: If the cancellation fails """ if not self.client: raise RuntimeError("Client not initialized. Check error property for details.") try: response = await self.http_client.post( f"/predictions/{prediction_id}/cancel", headers={ "Authorization": f"Bearer {self.api_token}", "Content-Type": "application/json", } ) response.raise_for_status() return response.json() except httpx.HTTPStatusError as err: if err.response.status_code == 404: raise ValueError(f"Prediction not found: {prediction_id}") logger.error(f"Failed to cancel prediction: {str(err)}") raise Exception(f"Failed to cancel prediction: {str(err)}") from err except Exception as err: logger.error(f"Failed to cancel prediction: {str(err)}") raise Exception(f"Failed to cancel prediction: {str(err)}") from err
- Pydantic model defining the structure of prediction responses, used as output type/schema for the tool.class Prediction(BaseModel): """A prediction (model run) on Replicate.""" id: str = Field(..., description="Unique identifier for this prediction") version: str = Field(..., description="Model version used for this prediction") status: PredictionStatus = Field(..., description="Current status of the prediction") input: Dict[str, Any] = Field(..., description="Input parameters used for the prediction") output: Optional[Any] = Field(None, description="Output from the prediction if completed") error: Optional[str] = Field(None, description="Error message if prediction failed") logs: Optional[str] = Field(None, description="Execution logs from the prediction") created_at: datetime started_at: Optional[datetime] = None completed_at: Optional[datetime] = None urls: Dict[str, str] = Field(..., description="Related API URLs for this prediction") metrics: Optional[Dict[str, float]] = Field(None, description="Performance metrics if available") stream_url: Optional[str] = Field(None, description="URL for streaming output if requested")
