Implementation Reference
- src/index.ts:417-466 (handler)The main handler function for the confirm_command tool. It retrieves the pending confirmation by ID, deletes it from the map, cancels if not confirmed, or executes the command using CommandExecutor and formats the output. Handles InvalidConfirmationError and other errors.async ({ confirmation_id, confirm }) => { try { const pending = this.pending_confirmations.get(confirmation_id); if (!pending) { throw new InvalidConfirmationError(confirmation_id); } this.pending_confirmations.delete(confirmation_id); if (!confirm) { return { content: [ { type: 'text' as const, text: 'Command execution cancelled.', }, ], }; } const result = await this.command_executor.execute_command( pending.command, pending.working_dir, pending.timeout, ); return { content: [ { type: 'text' as const, text: this.format_output(result), }, ], }; } catch (error) { return { content: [ { type: 'text' as const, text: `Error confirming command: ${ error instanceof Error ? error.message : String(error) }`, }, ], isError: true, }; } },
- src/index.ts:402-411 (schema)Valibot schema defining the input parameters: confirmation_id (string) and confirm (boolean).schema: v.object({ confirmation_id: v.pipe( v.string(), v.description('Confirmation ID'), ), confirm: v.pipe( v.boolean(), v.description('Proceed with execution'), ), }),
- src/index.ts:397-467 (registration)The registration of the confirm_command tool using this.server.tool, including name, description, schema, annotations, and handler.// confirm_command tool this.server.tool( { name: 'confirm_command', description: 'Confirm dangerous command execution', schema: v.object({ confirmation_id: v.pipe( v.string(), v.description('Confirmation ID'), ), confirm: v.pipe( v.boolean(), v.description('Proceed with execution'), ), }), annotations: { readOnlyHint: false, destructiveHint: true, }, }, async ({ confirmation_id, confirm }) => { try { const pending = this.pending_confirmations.get(confirmation_id); if (!pending) { throw new InvalidConfirmationError(confirmation_id); } this.pending_confirmations.delete(confirmation_id); if (!confirm) { return { content: [ { type: 'text' as const, text: 'Command execution cancelled.', }, ], }; } const result = await this.command_executor.execute_command( pending.command, pending.working_dir, pending.timeout, ); return { content: [ { type: 'text' as const, text: this.format_output(result), }, ], }; } catch (error) { return { content: [ { type: 'text' as const, text: `Error confirming command: ${ error instanceof Error ? error.message : String(error) }`, }, ], isError: true, }; } }, );
- src/index.ts:25-25 (helper)Class property storing pending confirmations, used by the confirm_command handler.private pending_confirmations: Map<string, PendingConfirmation>;
