- Around line 29-31: Update the URL validation in the agent base URL parsing
flow to reject parsed URLs with a non-empty RawQuery, ForceQuery, or fragment
before returning the base URL. Preserve the existing scheme and host checks.
- Around line 29-31: Update the URL validation around url.Parse in the
MOBILECLI_IOS_AGENT_URL handling to reject HTTP URLs containing user credentials
unless the host is loopback; continue allowing credentialed HTTPS URLs and
existing valid URLs without credentials.

- Around line 507-508: Update StartAgent and useExternalAgent to verify that an
external agent identified by agentURL belongs to the current IOSDevice, matching
its identity to d.Udid before storing or using the client; reject mismatches so
one device cannot bind to another device’s agent.

Check that the external agent belongs to this IOSDevice.
If two devices are available and the URL points to device A, StartAgent also binds an IOSDevice for device B to A. /health establishes liveness, not a match with d.Udid. Commands selected for B can therefore act on A. Check agent identity before storing the client, or require an explicit URL mapping by device ID.

When set, a real iOS device uses the DeviceKit agent at that URL after a health check, without listing apps, starting the go-ios tunnel, setting up a port forward, or launching the runner. Combined with DEVICEKIT_LISTEN_HOST (devicekit-ios#92) this drives a Wi-Fi paired iPhone through the Xcode CoreDevice tunnel address. The MJPEG URL now follows the agent base URL.

Accept <udid>=<url> pairs so each device uses only its own agent; a bare URL is used only while a single real iOS device is connected, since the agent cannot report which device it runs on.

Classify a value that parses as a single http(s) URL as a bare URL before treating '=' and ',' as mapping separators. The README now says the agent serves plain HTTP, so the URL should be loopback or the CoreDevice tunnel.

Summary
Adds a
MOBILECLI_IOS_AGENT_URLenvironment variable. When it is set, a real iOS device uses the on-device agent at that URL as is:StartAgentchecks its/healthand returns, without listing apps, starting the go-ios tunnel, setting up the port forward, or launching the runner. Every agent call (info,dump ui,screenshot, taps, swipes, keys, clipboard, orientation, MJPEG streaming) then goes to that URL.Combined with devicekit-ios
DEVICEKIT_LISTEN_HOST(mobile-next/devicekit-ios#92), this drives an iPhone paired over Wi-Fi only, with no USB and no go-ios tunnel: the agent listens on the Xcode CoreDevice tunnel address, and mobilecli talks to it there.This is the mobilecli side of mobile-next/mobile-mcp#483. Today a real iOS device can only reach its agent through a go-ios tunnel (iOS 17+) and a forward that mobilecli sets up itself. When that path is not available (for example a Wi-Fi paired iPhone), every agent command fails before reaching the agent, even if the agent is running and reachable another way.
Verified on a real device
iPhone 12 Pro, iOS 26.6.1, paired over Wi-Fi only (

/rpcrequest arriving from the Mac side of the tunnel. With the variable unset, the same device fails at the default agent path as before (here at the installed agent check, since the runner was installed under a different bundle id).Things worth knowing for the recipe:

/health,/rpc), not the WebDriver protocol. A plain WebDriverAgent URL will not work here.MOBILECLI_*variable style (MOBILECLI_DEVICE,MOBILECLI_DEVICE_SERVER_IDLE_TIMEOUT). It is read inStartAgent, so it lives in the daemon, which inherits the environment of the CLI that started it. The README says to runmobilecli daemon stopafter changing it.MOBILECLI_HOMEgives a separate daemon when another one is already running.MOBILECLI_IOS_AGENT_URLaccepts either a comma-separated list of<udid>=<url>pairs or a single URL. With pairs, each device uses only its own entry and any other device falls back to the normal tunnel and forward path. A single URL is accepted only while usbmuxd reports exactly one real iOS device (one cheap device list call, no per-device lockdown session); with more, startup fails with an error asking for<udid>=<url>. The agent cannot report which device it runs on (device.inforeturns only screen size and scale), so the explicit mapping is what binds a device to its agent. URLs with a query, fragment, or user info are rejected.http://andhttps://URLs with a host are accepted, including bracketed IPv6 literals. Anything else (including a query, fragment, or user info) fails with a clear error instead of falling back to the tunnel.localhost:<port>, so it follows the override. With the default client the URL is the same as before.::instead would expose an unauthenticated control server to the network.Changes
devices/ios_agent_url.go: read and validate the variable, and point the device at the external agent after a health check.devices/ios.go: use it at the top ofIOSDevice.StartAgent, and build the MJPEG URL from the agent base URL.devices/common.go,devices/devicekit/types.go: small helpers (buildMjpegURLForAgent,DeviceKitClient.BaseURL).README.md: document the variable and the Wi-Fi tunnel recipe in the Daemon section.devices/ios_agent_url_test.go: device-free tests with anhttptestagent, including one on[::1]for a bracketed IPv6 URL. The device under test is iOS 17 with no tunnel manager, so any tunnel, forward, or app listing attempt would fail the test.Testing
