# adb_perf_snapshot Capture a performance snapshot for a package: memory usage, frame stats, and CPU info in one call. Agent View of the PolicyLayer registry record for `adb_perf_snapshot`. HTML page: https://policylayer.com/tools/io-github-fullread-deepadb/adb-perf-snapshot ## Facts - Tool: `adb_perf_snapshot` - 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_perf_snapshot", "arguments": {} } } ``` ## Why adb_perf_snapshot is rated Low This tool reads performance telemetry about a running application without modifying, deleting, or executing commands on the device. It is a diagnostic/monitoring operation that gathers metrics for inspection. No state changes, code execution, or irreversible actions occur. Severity is low because even if misused by an agent, it only retrieves performance data already accessible on the device. From the tool's own definition: "Tool description states it 'captures' performance metrics (memory usage, frame stats, CPU info), which are retrieval/monitoring operations with no side effects. The verb 'capture' in the context of diagnostics means to collect and report existing data." ## Use case AI agents call adb_perf_snapshot 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_perf_snapshot": {} } } ``` ## 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.
