Implementation Reference

• src/tools/executions.ts:262-269 (handler)

  The handler function that executes the retry logic by calling the n8n API.

  async (params: z.infer<typeof IdParamSchema>) => {
    const execution = await post<N8nExecution>(`/executions/${params.id}/retry`);
    
    return {
      content: [{ type: 'text', text: `🔄 Execution retry started.\n\n${formatExecution(execution)}` }],
      structuredContent: execution
    };
  }

• src/tools/executions.ts:243-270 (registration)

  Registration of the n8n_retry_execution tool.

    server.registerTool(
      'n8n_retry_execution',
      {

        description: `Retry a failed execution.
  
  Args:
    - id (string): Execution ID to retry
  
  Returns:
    The new execution created from the retry.`,
        inputSchema: IdParamSchema,
        annotations: {
          readOnlyHint: false,
          destructiveHint: false,
          idempotentHint: false,
          openWorldHint: false
        }
      },
      async (params: z.infer<typeof IdParamSchema>) => {
        const execution = await post<N8nExecution>(`/executions/${params.id}/retry`);
        
        return {
          content: [{ type: 'text', text: `🔄 Execution retry started.\n\n${formatExecution(execution)}` }],
