hash_identifier_analyze · Kali MCP: Risk & Policy

WHAT IT DOES

What hash_identifier_analyze does on Kali

AI agents invoke hash_identifier_analyze to trigger actions in Kali. 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.

WHY IT NEEDS A POLICY

Why hash_identifier_analyze needs a policy

This tool runs the Hash-Identifier utility to analyze and identify hash types. It executes an external program but only performs read/analysis operations on provided hash strings with no side effects, network access, or data modification. Severity is low as misuse is limited to identifying hash algorithms, which is benign on its own, though it exists within a broader penetration testing context.

From the tool's definition "Execute Hash-Identifier hash type analyzer" — explicitly states execution of an external tool

Verdict

hash_identifier_analyze Rate-limited

hash_identifier_analyze stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Kali, so you can run agents against it safely.

FAQ

Questions about hash_identifier_analyze

What does the hash_identifier_analyze tool do? +

Execute Hash-Identifier hash type analyzer. It is categorised as a Execute tool in the Kali MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on hash_identifier_analyze? +

Register the Kali MCP server in PolicyLayer and add a rule for hash_identifier_analyze: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Kali. Nothing to install.

What risk level is hash_identifier_analyze? +

hash_identifier_analyze is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit hash_identifier_analyze? +

Yes. Add a rate_limit block to the hash_identifier_analyze rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block hash_identifier_analyze completely? +

Set action: deny in the PolicyLayer policy for hash_identifier_analyze. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides hash_identifier_analyze? +

hash_identifier_analyze is provided by the Kali MCP server (pentestt00ls/kali-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
