Use the Tauri MCP CLI to start and recover driver sessions, automate Tauri webviews, capture UI state, debug IPC, and work with mobile or remote devices. Use whenever an agent needs to operate a Tauri v2 app from terminal commands.

Tauri MCP CLI

Use this skill for the entire CLI workflow. The package intentionally ships a single bundled skill so agents do not need to pick between overlapping domain-specific skills.

Prerequisites

  • The app is running in development mode, usually with cargo tauri dev.
  • The tauri-plugin-mcp-bridge plugin is installed and registered.
  • src-tauri/tauri.conf.json sets withGlobalTauri: true.

Core Rule

Start or verify a driver session before calling almost any other tool:

bash
tauri-mcp driver-session start --port 9223
tauri-mcp driver-session status --json

driver-session start can succeed even when no app is reachable, so always check connected: true in the status output.

Session and Daemon Lifecycle

bash
# Start a session
tauri-mcp driver-session start --port 9223
# Run one or more commands in separate shell invocations
tauri-mcp webview-screenshot --file before.png
tauri-mcp webview-interact --action click --selector "#submit-btn"
tauri-mcp webview-screenshot --file after.png
# End the session
tauri-mcp driver-session stop

The CLI uses MCPorter keep-alive mode, so the background daemon preserves session state across separate tauri-mcp ... commands.

Use daemon commands only when the background process itself is unhealthy:

bash
tauri-mcp daemon status
tauri-mcp daemon restart
tauri-mcp driver-session start --port 9223

UI Interaction

bash
# Click or focus an element
tauri-mcp webview-interact --action click --selector "#submit-btn"
tauri-mcp webview-interact --action focus --selector "#search"
# Type into a field
tauri-mcp webview-keyboard --action type --selector "#email" --text "hello@example.com"
# Wait before interacting with async UI
tauri-mcp webview-wait-for --type selector --value "#success-msg" --timeout 5000
tauri-mcp webview-interact --action click --selector "#success-msg"
# Keyboard shortcuts and scrolling
tauri-mcp webview-keyboard --action press --key "s" --modifiers '["Control"]'
tauri-mcp webview-interact --action scroll --selector ".content" --scroll-y 300

All CLI flags are kebab-case, not camelCase. For example, use --window-id, not --windowId.

Inspection and Capture

bash
# Screenshots always write files to disk
tauri-mcp webview-screenshot --file shot.png
tauri-mcp webview-screenshot --format jpeg --quality 80 --file shot.jpg
tauri-mcp webview-screenshot --json
# Run JavaScript in the webview
tauri-mcp webview-execute-js --script "document.title"
tauri-mcp webview-execute-js --script "(() => { return document.querySelectorAll('li').length; })()"
# Find elements and inspect styles
tauri-mcp webview-find-element --selector "#hero"
tauri-mcp webview-get-styles --selector "#hero" --properties '["color","font-size"]'
# Read logs and inspect windows
tauri-mcp read-logs --source console --filter "error" --lines 100
tauri-mcp manage-window --action list --json

If content is off-screen, scroll it into view before taking a screenshot. The CLI does not return base64 image data on stdout.

IPC and Backend

bash
# Verify the bridge plugin is active
tauri-mcp driver-session status --json
# Run backend commands
tauri-mcp ipc-execute-command --command "greet" --args '{"name":"World"}'
tauri-mcp ipc-get-backend-state --json
# Capture IPC traffic around an interaction
tauri-mcp ipc-monitor --action stop
tauri-mcp ipc-monitor --action start
tauri-mcp webview-interact --action click --selector "#refresh"
tauri-mcp ipc-get-captured --json
tauri-mcp ipc-monitor --action stop
# Emit synthetic events
tauri-mcp ipc-emit-event --event-name "user-action" --payload '{"action":"button-clicked"}'

If driver-session status --json returns identifier: null, treat that as a missing or inactive bridge plugin.

Mobile and Remote Devices

bash
# List targets
tauri-mcp list-devices --json
# Android emulator or iOS simulator
tauri-mcp driver-session start --port 9223
# Real Android device
adb reverse tcp:9223 tcp:9223
tauri-mcp driver-session start --port 9223
# Real iOS device or direct network connection
tauri-mcp driver-session start --host 192.168.1.101 --port 9223
# Mobile logs
tauri-mcp read-logs --source android --filter "com.myapp"
tauri-mcp read-logs --source ios --filter "MyApp"

For real Android devices, do not assume localhost works without adb reverse or an explicit --host.

High-Value Failure Modes

No active session
bash
tauri-mcp driver-session start --port 9223
tauri-mcp driver-session status --json
Stale daemon or app restart
bash
tauri-mcp daemon restart
tauri-mcp driver-session start --port 9223
tauri-mcp driver-session status --json
Wrong port
bash
tauri-mcp driver-session start --port 9225
Screenshot misuse
bash
# Wrong: captures a file path string, not image bytes
IMG=$(tauri-mcp webview-screenshot)
# Right
tauri-mcp webview-screenshot --file shot.png
JavaScript return shape
bash
# Wrong: returns null
tauri-mcp webview-execute-js --script "() => { return document.title; }"
# Right
tauri-mcp webview-execute-js --script "document.title"
Missing selector for typed input
bash
# Wrong
tauri-mcp webview-keyboard --action type --text "hello"
# Right
tauri-mcp webview-keyboard --action type --selector "#email" --text "hello"

Decision Checklist

Before acting, verify:

  1. The app is running.
  2. driver-session status --json shows connected: true.
  3. The command uses kebab-case flags.
  4. Screenshot commands write to explicit file paths when the result matters.
  5. Mobile workflows specify the correct connection path and log source.
