# coverage_report Report which tools have been called in the current runtime and which known tools remain uncalled. Agent View of the PolicyLayer registry record for `coverage_report`. HTML page: https://policylayer.com/tools/io-github-vmoranv-jshookmcp/coverage-report ## Facts - Tool: `coverage_report` - Server: Jshookmcp (`@jshookmcp/jshook`) — https://policylayer.com/tools/io-github-vmoranv-jshookmcp.md - Install: `npx -y @jshookmcp/jshook` - Homepage: https://github.com/vmoranv/jshookmcp - 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": "coverage_report", "arguments": {} } } ``` ## Why coverage_report is rated Low This tool queries and reports on the state of tool invocations within the current runtime session. It retrieves information about which tools have been called and which have not been called, performing read-only analysis with no side effects, data modification, code execution, or destructive operations. The blast radius is minimal—misuse would only result in information disclosure about tool usage patterns. From the tool's own definition: "Tool name 'coverage_report' and description 'Report which tools have been called in the current runtime and which known tools remain uncalled' indicate retrieval and analysis of execution data with no modifications, deletions, or external operations." ## Use case AI agents call coverage_report to retrieve information from Jshookmcp 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 Jshookmcp: ```json { "version": "1", "default": "deny", "tools": { "coverage_report": {} } } ``` ## Other tools on Jshookmcp (735) - `adb_uninstall` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/adb-uninstall.md - `cleanup_artifacts` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/cleanup-artifacts.md - `clear_all_caches` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/clear-all-caches.md - `clear_collected_data` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/clear-collected-data.md - `dart_destroy_session` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/dart-destroy-session.md - `exploit_cache_clear` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/exploit-cache-clear.md - `exploit_cache_invalidate` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/exploit-cache-invalidate.md - `extension_uninstall` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/extension-uninstall.md - `ghidra_decompile` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/ghidra-decompile.md - `ida_decompile` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/ida-decompile.md - `jadx_decompile_apk` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/jadx-decompile-apk.md - `manual_token_cleanup` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/manual-token-cleanup.md - `memory_antidetection` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/memory-antidetection.md - `memory_batch_edit` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/memory-batch-edit.md - `memory_scan_session` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/memory-scan-session.md - `memory_unregister_type` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/memory-unregister-type.md - `nemu_destroy_session` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/nemu-destroy-session.md - `page_cookies` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/page-cookies.md - `page_local_storage` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/page-local-storage.md - `page_session_storage` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/page-session-storage.md - `proxy_clear_logs` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/proxy-clear-logs.md - `proxy_clear_rules` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/proxy-clear-rules.md - `proxy_remove_rule` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/proxy-remove-rule.md - `reset_token_budget` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/reset-token-budget.md - `session_progress_clear` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/session-progress-clear.md - `snapshot_restore` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/snapshot-restore.md - `tls_keylog_seal` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/tls-keylog-seal.md - `v8_heap_snapshot_delete` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/v8-heap-snapshot-delete.md - `webhook` — Destructive — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/webhook.md - `activate_tools` — Execute — https://policylayer.com/tools/io-github-vmoranv-jshookmcp/activate-tools.md - …and 705 more: https://policylayer.com/tools/io-github-vmoranv-jshookmcp.md ## For agents This record is a snapshot.
