# adb_firmware_diff Compare all firmware components between two saved OTA fingerprints, or between the current device state and a saved fingerprint. Compares baseband (with chipset-specific parsed component diffs), bootloader, kernel, security patch, build ID, and Android version. Agent View of the PolicyLayer registry record for `adb_firmware_diff`. HTML page: https://policylayer.com/tools/io-github-fullread-deepadb/adb-firmware-diff ## Facts - Tool: `adb_firmware_diff` - Server: Deepadb (`deepadb`) — https://policylayer.com/tools/io-github-fullread-deepadb.md - Install: `npx -y deepadb` - Homepage: https://github.com/fullread/DeepADB - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "adb_firmware_diff", "arguments": {} } } ``` ## Why adb_firmware_diff is rated Low This tool performs a comparison/diff operation between firmware states. It reads and analyzes existing data (baseband, bootloader, kernel, security patch, build ID, Android version) without modifying, executing, or deleting anything. The output is purely informational — a report of differences between two snapshots. From the tool's own definition: "Compare all firmware components between two saved OTA fingerprints, or between the current device state and a saved fingerprint" ## Use case AI agents call adb_firmware_diff to retrieve information from Deepadb without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Deepadb: ```json { "version": "1", "default": "deny", "tools": { "adb_firmware_diff": {} } } ``` ## Other tools on Deepadb (204) - `adb_clear_data` — Destructive — https://policylayer.com/tools/io-github-fullread-deepadb/adb-clear-data.md - `adb_file_move` — Destructive — https://policylayer.com/tools/io-github-fullread-deepadb/adb-file-move.md - `adb_forward_remove` — Destructive — https://policylayer.com/tools/io-github-fullread-deepadb/adb-forward-remove.md - `adb_logcat_clear` — Destructive — https://policylayer.com/tools/io-github-fullread-deepadb/adb-logcat-clear.md - `adb_qemu_images` — Destructive — https://policylayer.com/tools/io-github-fullread-deepadb/adb-qemu-images.md - `adb_result_drop` — Destructive — https://policylayer.com/tools/io-github-fullread-deepadb/adb-result-drop.md - `adb_reverse_remove` — Destructive — https://policylayer.com/tools/io-github-fullread-deepadb/adb-reverse-remove.md - `adb_rm` — Destructive — https://policylayer.com/tools/io-github-fullread-deepadb/adb-rm.md - `adb_tunnel_close` — Destructive — https://policylayer.com/tools/io-github-fullread-deepadb/adb-tunnel-close.md - `adb_uninstall` — Destructive — https://policylayer.com/tools/io-github-fullread-deepadb/adb-uninstall.md - `adb_a11y_audit` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-a11y-audit.md - `adb_airplane_cycle` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-airplane-cycle.md - `adb_airplane_mode` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-airplane-mode.md - `adb_at_batch` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-at-batch.md - `adb_at_probe` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-at-probe.md - `adb_at_send` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-at-send.md - `adb_batch_actions` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-batch-actions.md - `adb_build_and_install` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-build-and-install.md - `adb_ci_run_tests` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-ci-run-tests.md - `adb_ci_wait_boot` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-ci-wait-boot.md - `adb_connect` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-connect.md - `adb_disconnect` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-disconnect.md - `adb_dumpsys` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-dumpsys.md - `adb_emulator_start` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-emulator-start.md - `adb_emulator_stop` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-emulator-stop.md - `adb_farm_run` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-farm-run.md - `adb_file_chmod` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-file-chmod.md - `adb_file_chown` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-file-chown.md - `adb_force_stop` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-force-stop.md - `adb_forward` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-forward.md - …and 174 more: https://policylayer.com/tools/io-github-fullread-deepadb.md ## For agents This record is a snapshot.
