open-mobile-mcp
An MCP server for mobile automation that enables LLMs to interact with Android and iOS devices through screenshot, tap, swipe, log analysis, and app lifecycle management.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
device_listList connected active Android emulators and iOS simulators.
get_viewportCapture screenshot of a device. Returns the image (resized to ~800px width for efficiency) and metadata with both resized and original dimensions. Use originalWidth/originalHeight for coordinate calculations when tapping. For Android, if logicalWidth/Height are provided, they represent the UI coordi…
get_semantic_hierarchyGet pruned, semantic UI hierarchy as JSON.
capture_diffCompare two base64 images and return diff percentage.
tap_on_element🥇 RECOMMENDED: Tap on a UI element by selector. Finds the element and taps its center automatically. Prefer over device_tap. If observing a log triggered by this tap, spawn the wait_for_log subagent BEFORE tapping. NOTE: text matching is exact — if an element renders with an emoji prefix (e.g. '🇫�…
device_tap⚠️ Low-level: Tap at raw screen coordinates. Prefer tap_on_element for reliability. Use coordinates from the physical screenshot (originalWidth/originalHeight). On Android, this tool automatically scales coordinates if a display override (logical resolution) is detected.
device_typeType text into the device.
device_swipe⚠️ Low-level: Swipe from (x1,y1) to (x2,y2). Use this for custom gestures or when you need precise swipe control. Use coordinates from the physical screenshot (originalWidth/originalHeight). On Android, this tool automatically scales coordinates if a display override (logical resolution) is detected…
analyze_layout_healthAnalyze the UI layout for performance or health issues (e.g. deep nesting).
device_pinchPerform a pinch gesture (two-finger zoom) on the device. Use 'out' to zoom in (fingers spread apart) and 'in' to zoom out (fingers come together). Works on real Android phones (no root needed) via UIAutomation MotionEvent injection.
device_press_keyPress a hardware or system key. Also accepts raw Android keycodes as numbers.
device_rotate_gesturePerform a two-finger rotation gesture (e.g. to rotate a map or image). Positive degrees = clockwise. Android only (uses UIAutomation, no root needed).
clear_app_dataClear all data and cache for an app (equivalent to Settings → App → Clear Data). Resets the app to a fresh-install state. Useful for testing onboarding or reproducing first-launch bugs.
get_app_infoGet version, install date, SDK target, data directory, and granted/denied permissions for an installed app. Android only.
start_recordingStart screen recording on the device. Use an absolute path for localPath when stopping to ensure you can find the file.
stop_recordingStop screen recording and save the file. Use an absolute path for localPath to ensure you can find the file.
run_maestro_flowRun a complex Maestro flow via YAML.
manage_bundlerStart, stop, or restart the Metro bundler. Platform logs (Android/iOS) auto-start by default. On Android, pass both deviceId and packageId to enable PID-based log filtering — this captures only your app's logs and eliminates all system/GMS noise.
get_network_logsPull network-related logs from the device. For Android, filters logcat. For iOS, filters the internal log capture buffer (must be running via manage_platform_logs or manage_bundler). For Expo / React Native apps, all console.log output (including fetchApi network traces) is emitted under the 'ReactN…
get_bundler_logsGet recent logs from Metro bundler, Android, or iOS. To wait for a specific line, use wait_for_log in a background subagent instead of polling.
wait_for_logBlock until a log line matching a pattern appears, or timeout. Returns {matched, line, elapsed}. ALWAYS use via background subagent — never call directly or it blocks the whole conversation: 1. Spawn background subagent: 'Call wait_for_log(pattern, timeout). Report result.' 2. Then perform the …
stream_errorsGet recent error logs from Metro, Android, and iOS. To wait for a specific error, use wait_for_log(pattern: 'error|exception') in a background subagent instead of polling.
manage_platform_logsManually start/stop platform log capture (optional - auto-starts with bundler). On Android, pass both deviceId and packageId to enable PID-based filtering — this captures only your app's logs and eliminates all system/GMS noise. Without packageId, falls back to ReactNative/AndroidRuntime tag filteri…
run_doctorRun npx expo-doctor.
install_depsInstall dependencies using npx expo install.
manage_app_lifecycleLaunch, stop, install, or uninstall apps.
open_deep_linkOpen a deep link or URL on the device.
get_screen_textGet all text visible on screen using OCR.
configure_ocrSet the default OCR language for the session.
find_elementFind UI elements by selector. Returns elements with pre-parsed coordinates (centerX, centerY, left, top, right, bottom, width, height) ready for use. For tapping, prefer tap_on_element which does find+tap in one step.
wait_for_elementWait for a UI element to appear (polls every 1s).
get_element_imageGet a cropped screenshot of a specific UI element.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
32/32 tools missing one or more hints — device_list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_viewport (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_semantic_hierarchy (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +29 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
5 calls in production code run through a shell (src/environment/metro.ts:105, src/environment/metro.ts:222, src/environment/metro.ts:230)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 1 high severity in production deps — @modelcontextprotocol/sdk@1.25.2 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dependency freshness
2/7 production deps stale: pngjs@2023-02-20 (3.5y), xml2js@2024-05-31 (2.3y)
