# aidefence_is_safe Quick boolean check if input is safe. Fastest option for simple validation. Use when nothing native exists — Claude Code does not have a PII / prompt-injection / adversarial-text scanner. Pair with any tool that ingests untrusted input (browser scrape, federation envelope, memory_import_claude). Agent View of the PolicyLayer registry record for `aidefence_is_safe`. HTML page: https://policylayer.com/tools/io-github-ruvnet-claude-flow/aidefence-is-safe ## Facts - Tool: `aidefence_is_safe` - Server: Claude Flow (`claude-flow`) — https://policylayer.com/tools/io-github-ruvnet-claude-flow.md - Install: `npx -y claude-flow` - Homepage: https://github.com/ruvnet/claude-flow - 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": "aidefence_is_safe", "arguments": {} } } ``` ## Why aidefence_is_safe is rated Low This tool queries or evaluates input data to determine safety status without modifying, creating, deleting, or executing external operations. It is purely an informational check that returns a boolean value. The blast radius of misuse is minimal since it only informs decisions rather than directly effecting changes. Classification as Read is appropriate for a validation/scanning function. From the tool's own definition: "Tool performs a 'Quick boolean check if input is safe' and is described as a validation scanner for PII/prompt-injection/adversarial-text detection. It returns a boolean result with no side effects mentioned." ## Use case AI agents call aidefence_is_safe to retrieve information from Claude Flow 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 Claude Flow: ```json { "version": "1", "default": "deny", "tools": { "aidefence_is_safe": {} } } ``` ## Other tools on Claude Flow (495) - `agent_terminate` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/agent-terminate.md - `agentdb_batch` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/agentdb-batch.md - `agentdb_causal-edge-delete` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/agentdb-causal-edge-delete.md - `agentdb_causal-node-delete` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/agentdb-causal-node-delete.md - `agentdb_hierarchical-delete` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/agentdb-hierarchical-delete.md - `agenticow_rollback` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/agenticow-rollback.md - `autopilot_reset` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/autopilot-reset.md - `config_reset` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/config-reset.md - `federation_wg_keyrotate` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/federation-wg-keyrotate.md - `hooks_codemod` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/hooks-codemod.md - `hooks_intelligence-reset` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/hooks-intelligence-reset.md - `hooks_worker-cancel` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/hooks-worker-cancel.md - `iot_device_remove` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/iot-device-remove.md - `iot_firmware_rollout_rollback` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/iot-firmware-rollout-rollback.md - `iot_fleet_delete` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/iot-fleet-delete.md - `iot_fleet_remove_device` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/iot-fleet-remove-device.md - `managed_agent_terminate` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/managed-agent-terminate.md - `memory_delete` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/memory-delete.md - `policy_revoke` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/policy-revoke.md - `ruvector_delete` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/ruvector-delete.md - `session_delete` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/session-delete.md - `system_reset` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/system-reset.md - `task_cancel` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/task-cancel.md - `teammate_cleanup` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/teammate-cleanup.md - `wasm_agent_reset` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/wasm-agent-reset.md - `wasm_gallery_remove_custom` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/wasm-gallery-remove-custom.md - `workflow_cancel` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/workflow-cancel.md - `workflow_delete` — Destructive — https://policylayer.com/tools/io-github-ruvnet-claude-flow/workflow-delete.md - `agent_pool` — Execute — https://policylayer.com/tools/io-github-ruvnet-claude-flow/agent-pool.md - `agent_spawn` — Execute — https://policylayer.com/tools/io-github-ruvnet-claude-flow/agent-spawn.md - …and 465 more: https://policylayer.com/tools/io-github-ruvnet-claude-flow.md ## For agents This record is a snapshot.
