# adb_emulator_start Launch an Android Virtual Device (AVD) emulator. Returns once the emulator process has started. Agent View of the PolicyLayer registry record for `adb_emulator_start`. HTML page: https://policylayer.com/tools/io-github-fullread-deepadb/adb-emulator-start ## Facts - Tool: `adb_emulator_start` - Server: Deepadb (`deepadb`) — https://policylayer.com/tools/io-github-fullread-deepadb.md - Install: `npx -y deepadb` - Homepage: https://github.com/fullread/DeepADB - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "adb_emulator_start", "arguments": {} } } ``` ## Why adb_emulator_start is rated High This tool triggers execution of an Android emulator process, which is an external operation whose side effects (resource consumption, emulator state, network interfaces, etc.) depend on emulator configuration and system state. The blast radius is high because an uncontrolled emulator launch could exhaust system resources, create security boundaries, or enable further attacks on the emulated Android system. From the tool's own definition: "Tool name 'adb_emulator_start' and description 'Launch an Android Virtual Device (AVD) emulator' indicate the tool starts/launches an external process or service." ## Use case AI agents invoke adb_emulator_start to trigger actions in Deepadb. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Deepadb: ```json { "version": "1", "default": "deny", "tools": { "adb_emulator_start": { "limits": [ { "counter": "adb_emulator_start_rate", "window": "minute", "max": 10, "scope": "grant" } ] } } } ``` ## 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_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 - `adb_gradle` — Execute — https://policylayer.com/tools/io-github-fullread-deepadb/adb-gradle.md - …and 174 more: https://policylayer.com/tools/io-github-fullread-deepadb.md ## For agents This record is a snapshot.
