Dual-Mode Architecture

DeepADB operates in two modes, auto-detected at startup:

ADB Mode (default) — PC-side bridge

AI Agent (PC) ←→ MCP ←→ DeepADB (PC) ←→ ADB (USB) ←→ Android Device

Standard mode: DeepADB runs on a PC/Mac/Linux host and communicates with the device over USB via ADB. All 204 tools work through the ADB bridge with automatic retry on transient failures.

On-Device Mode — direct local execution

AI Agent (Termux) ←→ MCP (stdio/HTTP) ←→ DeepADB (Termux) ←→ sh/su (local)

When DeepADB runs directly on the Android device (e.g., inside Termux), it auto-detects the environment and switches to LocalBridge. Commands execute directly via sh/su — no ADB server, no USB, no serialization overhead. All 204 tools work identically, with significantly lower latency.

Validated on hardware (Pixel 6a, Android 16, Termux + Magisk + QEMU 10.2.1) across a four-cell test matrix — host (ADB) and on-device (LocalBridge), each with and without a device PIN — with 0 failures in every cell. The full suite is 577 tests in the host/ADB configuration and 613 on-device; the difference is the QEMU virtualization and Alpine VM-boot suites, which run only on-device:

• ADB mode, no PIN: 556 passed / 0 failed / 21 skipped (577 total). Skips: 5 QEMU (on-device only), 7 gracefulKill unit tests (require POSIX signals, skipped on the Windows host), 3 tcpdump sanitization (tcpdump is root-only and unreachable over a non-root ADB shell), 2 host-shell round-trips (require a POSIX /bin/sh), 4 screen-state (require DA_TEST_PIN).
• ADB mode, with PIN: 560 passed / 0 failed / 17 skipped (577 total). The 4 screen-state tests unlock and run.
• On-device mode, no PIN: 606 passed / 0 failed / 7 skipped (613 total). All QEMU tests run, including Alpine Linux VM boot with KVM acceleration, big.LITTLE CPU topology detection, guest ADB connectivity error handling, and clean VM shutdown; the tcpdump and gracefulKill suites also run here (root + POSIX). Skips: 3 QEMU setup steps that no-op when the Alpine kernel/initrd/disk are already cached, 4 screen-state (require PIN).
• On-device mode, with PIN: 610 passed / 0 failed / 3 skipped (613 total). Every test enabled by the environment runs; the 3 skips are the cached-VM setup steps.

Privilege escalation: In ADB mode, all shell commands run as uid=2000 (the shell user) which has system-level permissions. In Termux, commands run as a regular app user. LocalBridge automatically elevates privileged commands through su when root (Magisk) is available:

• Command allowlist: 16 system commands (settings, dumpsys, am, input, screencap, screenrecord, uiautomator, app_process, getenforce, setenforce, cmd, pm, wm, svc, ip, ifconfig) are routed through su -c to match ADB-mode behavior.
• Path-based elevation: Commands referencing /sdcard, /storage, or /system/ paths are elevated to bypass Android scoped storage restrictions.
• Root detection: Cached after a single su -c id probe at first use. Graceful degradation when root is unavailable.
• The elevation allowlist is frozen (ReadonlySet + Object.freeze) — not configurable via environment variables or runtime API.

Auto-detection: Checks for /system/build.prop (present on all Android devices, never on hosts). Override with DA_LOCAL=true or DA_LOCAL=false.

On-device setup (Termux):

pkg install nodejs-lts git
git clone <deepadb-repo> && cd deepadb
npm install && npm run build
npm start                              # stdio — for local AI agents (Claude Code, OpenCode)
DA_HTTP_PORT=3000 npm start            # HTTP/SSE — for remote AI access over WiFi

Key Features

Device Caching

Device discovery results are cached with a configurable TTL (default 5s), eliminating redundant adb devices subprocess calls during rapid tool sequences. Cache auto-invalidates on connection errors and after wireless connect/disconnect/pair operations.

Transient Failure Retry

The ADB bridge automatically retries on transient failures (device offline, connection reset, protocol fault) with configurable retry count and exponential backoff. Diagnostic commands skip retries to surface real issues immediately.

Output Protection

All ADB output passes through the OutputProcessor which normalizes line endings, enforces configurable character limits, and provides contextual truncation at logical boundaries (line breaks, section separators) rather than cutting mid-line. Includes structured parsers for battery, meminfo, and getprop output.

Persistent Logcat Streaming

Background logcat watchers run as spawned processes with ring buffer accumulation. Each poll returns only new lines since the last read. Supports multiple concurrent sessions (up to 10) with independent filters. Process cleanup handlers prevent orphaned adb logcat processes on server exit.

UI Hierarchy Analysis

Full view tree capture via uiautomator dump with parsed XML extraction. Returns structured element data including text, resource-id, content-description, class names, bounds coordinates with tap-ready center points, and interaction flags. Pre-compiled regex attribute extraction for efficient parsing.

Security Middleware

Multi-layered security activated via DA_SECURITY=true. Provides command blocklist/allowlist filtering, rate limiting (commands per minute), and audit logging with automatic credential redaction. Security checks are integrated into adb_shell, adb_root_shell, adb_multi_shell, adb_multi_compare, adb_input, adb_batch_actions, and adb_start_activity. Configurable via environment variables for different deployment scenarios.

Input Sanitization

All tools that interpolate user-supplied parameters into shell command strings validate inputs against shell metacharacters before execution. Package names, property keys, service names, setting keys, test identifiers, network interface names, and tcpdump filters are all validated through a centralized validateShellArg() function that rejects ;, |, &, $, backticks, parentheses, and other injection vectors. File paths use single-quoted shell escaping to prevent $() command substitution. The adb_input tool applies type-specific validation: tap/swipe accept only numeric coordinates, keyevent accepts only alphanumeric keycodes, and text is shell-escaped for literal delivery. The adb_batch_actions tool enforces the same per-action-type validation (digits-only for coordinates, alphanumeric for keycodes, shell-escape for text) and routes every assembled command through the security middleware. Deserialized JSON from snapshot files is validated before shell interpolation. Every z.number() parameter across all 204 tools has explicit .min()/.max() Zod bounds to prevent resource exhaustion from extreme values. The LocalBridge has explicit handlers for every ADB subcommand used by tool modules, preventing unquoted fallthrough to the default shell handler. In on-device mode, privilege escalation uses a frozen 16-command allowlist and restricted-path regex — the elevation set is ReadonlySet + Object.freeze, not configurable at runtime. The HTTP/SSE transport denies cross-origin requests by default (configurable via DA_HTTP_CORS_ORIGIN), the plugin registry verifies SHA-256 integrity hashes and prevents path traversal via directory containment checks, and the workflow engine enforces step count (200), sleep duration (5 min), and repeat iteration (100) limits. Fetch helpers enforce a 5 MB response body limit. Getprop output parsing handles Windows \r\n line endings via .trim() before regex matching, and dual SIM slot counts are capped at 4 to prevent resource exhaustion from corrupted device properties.

Multi-Device Orchestration

Run commands, install APKs, and compare outputs across multiple connected devices in parallel. Essential for comparative testing across Android versions and device models.

Snapshot/Restore

Capture comprehensive device state snapshots (packages, settings across all namespaces, system properties) to JSON files. Compare current state against saved snapshots to detect drift. Restore settings from snapshots for reproducible test environments.

Network Traffic Capture

On-device packet capture via tcpdump with pcap file pull for Wireshark analysis. Includes active connection listing via ss/netstat with /proc/net fallback for devices without those tools.

CI/CD Integration

Purpose-built tools for automated pipelines: wait for device boot with polling, structured readiness checks, and instrumented test execution with parsed pass/fail results.

Plugin Architecture

Dynamic tool module loading from a configurable plugins directory. Plugins are standard JavaScript ESM modules that export a register(ctx) function receiving the full ToolContext. Loaded at server startup, enabling community contributions without modifying core code.

Community Plugin Registry

Search, install, and manage plugins from a configurable registry URL. Shows install status, version comparison, and available updates. Downloads plugin files with companion metadata into the plugins directory for loading on next restart. Security features include SHA-256 integrity verification (when provided by the registry manifest), path traversal protection, and register() export sanity checking.

Baseband/Modem Integration

Deep cellular radio inspection tools for advanced Android development and research. Extracts modem firmware identification, cell identity parameters (CID, TAC, EARFCN, PCI), raw signal measurements (RSRP, RSRQ, SINR), neighboring cell surveys, carrier configuration, and multi-source modem logs (RIL radio buffer, telephony framework, kernel dmesg). Supports Shannon/Exynos, Qualcomm, MediaTek, and Unisoc chipset families via standard Android telephony APIs. Includes Google Tensor SoC detection (gs101/gs201/zuma/zumapro) for automatic Shannon modem path routing on Pixel 6–9 devices. Dual SIM detection reports per-slot SIM state, operator, network type, and country for DSDS, DSDA, and TSTS configurations.

Accessibility Auditing

Automated WCAG accessibility checks on the live UI hierarchy. Detects missing labels on interactive elements, undersized touch targets below the 48dp guideline (density-aware), images without content-descriptions, clickable elements missing focusability, and duplicate content-descriptions. Generates structured reports with severity levels. Includes a dedicated accessibility tree view for screen reader debugging.

Regression Detection

Capture performance baselines (memory, CPU, frame stats, battery, network state) and compare subsequent runs against them. Configurable regression thresholds for memory (+20%), CPU (+50%), and jank rate (+25%). Maintains a history of baselines for trend analysis across releases.

Device Farm Integration

Cloud-based test execution via Firebase Test Lab through the gcloud CLI. Run instrumented tests across multiple device models and API levels, retrieve structured results, and list available test matrix configurations. Graceful fallback with setup instructions if gcloud is unavailable.

HTTP/SSE Transport

Alternative to stdio for browser-based MCP clients. Set DA_HTTP_PORT to start an HTTP server with SSE streaming. Provides /sse (client subscription), /message (JSON-RPC), and /health endpoints. Cross-origin requests are denied by default — set DA_HTTP_CORS_ORIGIN to explicitly allow a specific origin.

Test Session Management

Structured test workflows with numbered steps. Each step captures a screenshot and logcat snapshot into an organized directory with a Markdown manifest. Designed for reproducible test documentation.

AT Command Interface

Direct AT command passthrough to the modem via root access, enabling raw interrogation beyond the Android telephony framework. Multi-chipset support auto-detects device nodes for Samsung Shannon/Exynos, Qualcomm Snapdragon, MediaTek, Unisoc/Spreadtrum, and generic USB modems. Input validation rejects shell metacharacters from both AT command strings and device node paths before root shell interpolation. A safety blocklist prevents accidental execution of dangerous commands (AT+CFUN=0, AT+EGMR, etc.) with an explicit force override.

Screenshot Diffing

True pixel-level visual regression detection. Captures named screenshot baselines and compares the current screen state by decoding PNG pixel data (IHDR parsing, IDAT decompression, all 5 PNG filter types) and comparing actual RGB values. Reports changed pixel count and percentage, bounding box of the changed region with vertical screen position, and dimension/size deltas. Supports a tolerancePercent parameter (0–100) that absorbs minor dynamic changes like clock displays or notification badges — a 1% tolerance reliably absorbs nav bar clock changes (~0.5% of pixels) while catching any real UI regression. SHA-256 fast-path for exact matches. Zero external dependencies.

Workflow Orchestration

Declarative JSON workflow engine for repeatable multi-step device operations. Supports variable substitution ({{pkg}}), conditional steps (if expressions with ==, !=, contains), loops (repeat, capped at 100 iterations), and result capture into variables for downstream steps. Actions map directly to ADB bridge operations with full security middleware enforcement. Workflow validation enforces a 200-step maximum and 5-minute sleep cap per step to prevent resource exhaustion from malicious or malformed workflow definitions.

Split APK Management

Support for modern Android delivery formats. Install app bundles via install-multiple, inspect split APK structure (base + config splits for language, density, ABI), extract all splits locally for analysis, and list APEX modules.

Device Mirroring

Live screen mirroring via scrcpy integration. Supports windowed mode for visual feedback and headless mode for recording-only workflows. Per-device session tracking enables simultaneous mirroring of multiple connected devices. Process cleanup handlers prevent orphaned scrcpy processes.

Automated Test Generation

Analyzes live UI hierarchy and package intent registrations to auto-generate test workflow JSON compatible with the workflow orchestration engine. UI-based generation taps each interactive element, screenshots, and checks for crashes. Intent-based generation launches each exported activity with crash detection.

OTA Update Monitoring

Tracks comprehensive system fingerprint (build ID, Android version, security patch, bootloader, baseband firmware, kernel version, A/B partition slot) across sessions. Compares current state against saved fingerprints to detect OTA updates. Identifies exactly which fields changed and recommends re-baselining performance metrics and screenshots after updates.

RIL Message Interception

Persistent Radio Interface Layer message capture from the Android radio logcat buffer. Spawns a background process that accumulates and categorizes RIL messages into: registration, cell_info, signal, network, security, handover, data, radio_state, sms, and NAS events. Poll-based retrieval with category filtering. Useful for passive monitoring of baseband-framework communication for radio diagnostics and cellular network research. Session limit (5) and process cleanup handlers prevent resource exhaustion.

Device Profile Library

Device-specific knowledge base containing hardware identification, chipset family, known modem device nodes, AT command compatibility, root requirements, dual SIM slot count, and quirks. Auto-detects profiles from connected devices and matches against a built-in library of known devices. Saved profiles persist across sessions and improve auto-detection accuracy for tools like adb_at_detect. Community-extensible through saved profile files.

WebSocket Transport

Alternative to stdio and HTTP/SSE for MCP clients that benefit from true bidirectional streaming. Lower latency than SSE polling with better web framework compatibility. Requires the ws npm package as an optional peer dependency. Set DA_WS_PORT to enable.

Modem Firmware Analysis

Comprehensive multi-component firmware identification, diffing, and history tracking. Parses baseband version strings for 6 chipset families: Shannon/Exynos (including Google Pixel/Tensor g5123b-* format and classic Samsung S5123AP_CL* format), Qualcomm MPSS branch/version/build, MediaTek MOLY branch/release/milestone, Unisoc/Spreadtrum SoC model/version, HiSilicon/Kirin model/carrier code, and Intel XMM model/branch. Also parses bootloader versions (Pixel codename/version/build, Samsung model/carrier/revision) and RIL implementation strings (Samsung S.LSI vendor/id/API/build date, Qualcomm, MediaTek). The firmware probe reports 8 sections: baseband, bootloader, RIL, kernel, security/build, partition/boot (A/B slot, secure boot, verified boot, flash lock), VBMeta integrity, and OTA partition inventory. The diff tool compares all firmware components between saved fingerprints or live device state, with deep parsed sub-diffs for baseband and bootloader. The history tool tracks multi-component firmware progression across OTA fingerprints.

Workflow Marketplace

Community sharing layer for the workflow orchestration engine. Search a registry of community-contributed test workflows, diagnostic sequences, and audit procedures. Download and install workflows directly for immediate execution with adb_workflow_run. Export local workflows with marketplace metadata and auto-generated registry manifest entries for submission. SHA-256 integrity verification on download.

GraphQL API

Optional HTTP endpoint serving a GraphQL API for composed device queries. Enables clients to fetch device info, battery, network, and arbitrary properties in a single request instead of multiple MCP tool calls. POST body size limited to 1 MB. Device properties are pre-fetched once per resolution to minimize subprocess calls. Requires the graphql npm package as an optional peer dependency. Set DA_GRAPHQL_PORT to enable.

SELinux & Permission Auditing

Inspects SELinux enforcement mode, queries AVC denials from logcat and kernel audit logs, and audits runtime permission grants per package. Groups granted permissions by dangerous category (Camera, Location, Phone, SMS, etc.) and flags high-sensitivity grants like background location and manage-external-storage. Extends the security auditing surface to the OS permission layer.

Thermal & Power Profiling

Captures thermal zone temperatures from sysfs, per-CPU frequency scaling states and governors, cooling device activity, and battery drain rates. Complements regression detection with thermal/power baselines for issues that manifest as heat or battery drain rather than frame drops. Includes timed drain measurement with mA/mW/estimated-%per-hour calculations.

Network Device Discovery

Scans the local network for ADB-enabled devices via ARP table queries and optional IP range sweeps. Probes common ADB ports (5555-5558) with batched parallel TCP connection attempts. Extracts device WiFi IPs via multiple methods. Auto-connect mode discovers and connects to devices in one step. Streamlines wireless debugging workflows.

QEMU/KVM Virtualization

On-device virtual machine management using QEMU with KVM hardware acceleration. Enables running guest Android VMs directly on the physical device — a capability unique to DeepADB. Dynamic resource allocation auto-detects host CPU cores and physical RAM, reserving 1 core and 35% of memory for the host OS to prevent starvation. Multi-VM support tracks resource consumption across concurrent VMs, refusing new VMs when the pool is exhausted rather than degrading host performance. Disk image management with qcow2 (sparse, snapshot-capable) and raw formats. ADB port forwarding to guest VMs enables DeepADB's full tool suite to target both host and guest devices simultaneously. Process lifecycle tracked via the centralized cleanup registry with SIGTERM/SIGKILL shutdown. Path containment verification on all image operations prevents directory traversal.

ToolContext Architecture

All 45 tool modules receive a unified ToolContext dependency bundle containing server, bridge, deviceManager, logger, security, and config. Adding new cross-cutting dependencies requires no module signature changes.
