swift_package_stop
Terminate a running Swift Package executable by specifying its process ID (PID) using this tool. Integrates with XcodeBuildMCP for efficient process management.

Implementation Reference
- Defines the Zod schema for input parameters (pid) of the swift_package_stop tool.
const swiftPackageStopSchema = z.object({ pid: z.number().describe('Process ID (PID) of the running executable'), }); - Core handler function that stops the Swift Package process by PID: retrieves process info, sends SIGTERM/SIGKILL, removes from active list, and returns response.
export async function swift_package_stopLogic( params: SwiftPackageStopParams, processManager: ProcessManager = getDefaultProcessManager(), timeout: number = 5000, ): Promise<ToolResponse> { const processInfo = processManager.getProcess(params.pid); if (!processInfo) { return createTextResponse( `⚠️ No running process found with PID ${params.pid}. Use swift_package_run to check active processes.`, true, ); } try { processInfo.process.kill('SIGTERM'); // Give it time to terminate gracefully (configurable for testing) await new Promise((resolve) => { let terminated = false; processInfo.process.on('exit', () => { terminated = true; resolve(true); }); setTimeout(() => { if (!terminated) { processInfo.process.kill('SIGKILL'); } resolve(true); }, timeout); }); processManager.removeProcess(params.pid); return { content: [ { type: 'text', text: `✅ Stopped executable (was running since ${processInfo.startedAt.toISOString()})`, }, { type: 'text', text: `💡 Process terminated. You can now run swift_package_run again if needed.`, }, ], }; } catch (error) { const message = error instanceof Error ? error.message : String(error); return createErrorResponse('Failed to stop process', message); } } - src/mcp/tools/swift-package/swift_package_stop.ts:104-120 (registration)Default export registering the tool with name, description, schema, and a thin handler that validates inputs and delegates to the core logic.
