# web_search Search the web using DuckDuckGo and return the top results (title, URL, snippet). Agent View of the PolicyLayer registry record for `web_search`. HTML page: https://policylayer.com/tools/io-github-ruvnet-claude-flow/web-search ## Facts - Tool: `web_search` - 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": "web_search", "arguments": {} } } ``` ## Why web_search is rated Low This tool performs a read-only query against a public search engine and returns informational results. It retrieves data without modifying, executing external commands, deleting, or moving funds. The blast radius of misuse is minimal—an agent could retrieve potentially inappropriate or irrelevant search results, but cannot cause damage or irreversible changes. From the tool's own definition: "Tool name 'web_search' and description 'Search the web using DuckDuckGo and return the top results (title, URL, snippet)' indicates a retrieval operation with no side effects." ## Use case AI agents call web_search 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": { "web_search": {} } } ``` ## 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.
