# tools_katana A execute tool on the Zebbern Kali MCP MCP server. Agent View of the PolicyLayer registry record for `tools_katana`. HTML page: https://policylayer.com/tools/zebbern-zebbern-kali-mcp/tools-katana ## Facts - Tool: `tools_katana` - Server: Zebbern Kali MCP (`zebbern/zebbern-kali-mcp`) — https://policylayer.com/tools/zebbern-zebbern-kali-mcp.md - Homepage: https://github.com/zebbern/zebbern-kali-mcp - 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": "tools_katana", "arguments": {} } } ``` ## Why tools_katana is rated High Despite an empty description, the server context makes clear this is an offensive security tool. 'Katana' in the Kali Linux ecosystem refers to a fast web crawler/attack surface discovery tool. Given the sibling tools (credential dumping, password spraying, remote execution), this tool likely executes active reconnaissance or attack operations against target systems. From the tool's own definition: "Tool is part of 'Zebbern Kali MCP', a Kali Linux penetration testing toolkit. Katana is a well-known offensive security tool (fast web crawler/scanner by ProjectDiscovery, or the katana framework)." ## Use case AI agents invoke tools_katana to trigger actions in Zebbern Kali MCP. 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 Zebbern Kali MCP: ```json { "version": "1", "default": "deny", "tools": { "tools_katana": { "limits": [ { "counter": "tools_katana_rate", "window": "minute", "max": 10, "scope": "grant" } ] } } } ``` ## Other tools on Zebbern Kali MCP (132) - `callback_clear` — Destructive — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/callback-clear.md - `hosts_clear` — Destructive — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/hosts-clear.md - `hosts_remove` — Destructive — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/hosts-remove.md - `msf_session_destroy` — Destructive — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/msf-session-destroy.md - `msf_session_destroy_all` — Destructive — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/msf-session-destroy-all.md - `pivot_remove` — Destructive — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/pivot-remove.md - `ad_asreproast` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/ad-asreproast.md - `ad_bloodhound_collect` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/ad-bloodhound-collect.md - `ad_kerberoast` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/ad-kerberoast.md - `ad_ldap_enum` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/ad-ldap-enum.md - `ad_password_spray` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/ad-password-spray.md - `ad_psexec` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/ad-psexec.md - `ad_secretsdump` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/ad-secretsdump.md - `ad_wmiexec` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/ad-wmiexec.md - `api_auth_bypass_test` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/api-auth-bypass-test.md - `api_ffuf_fuzz` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/api-ffuf-fuzz.md - `api_fuzz_endpoint` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/api-fuzz-endpoint.md - `api_graphql_fuzz` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/api-graphql-fuzz.md - `api_jwt_crack` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/api-jwt-crack.md - `api_kiterunner_scan` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/api-kiterunner-scan.md - `api_newman_run` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/api-newman-run.md - `api_nuclei_scan` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/api-nuclei-scan.md - `api_rate_limit_test` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/api-rate-limit-test.md - `callback_check` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/callback-check.md - `callback_generate` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/callback-generate.md - `callback_latest` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/callback-latest.md - `callback_start` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/callback-start.md - `callback_stop` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/callback-stop.md - `callback_wait` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/callback-wait.md - `ctf_connect` — Execute — https://policylayer.com/tools/zebbern-zebbern-kali-mcp/ctf-connect.md - …and 102 more: https://policylayer.com/tools/zebbern-zebbern-kali-mcp.md ## For agents This record is a snapshot.
