What hashid does on Nyxstrike
AI agents call hashid to retrieve information from Nyxstrike without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why hashid is rated Low
hashid is a standard hash identification utility that reads/analyzes a hash string and returns the probable hash algorithm(s) it represents. It does not modify, delete, or execute anything — it is a passive read/analysis operation. However, in the context of an offensive security platform, hash identification is a step in credential cracking workflows, raising the severity slightly.
From the tool's definition Tool name 'hashid' with empty description; on a penetration testing platform, hashid is a well-known tool for identifying hash types from hash strings.
Attacks that exploit this kind of access
The rule that runs hashid safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Nyxstrike, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hashid, this is the rule to start with:
hashid is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Nyxstrike, apply this rule, and every hashid call is checked against it from then on.
Questions about hashid
hashid is a read tool on the Nyxstrike MCP server. It is categorised as a Read tool in the Nyxstrike MCP Server, which means it retrieves data without modifying state.
Register the Nyxstrike MCP server in PolicyLayer and add a rule for hashid: 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 Nyxstrike. Nothing to install.
hashid is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the hashid 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.
Set action: deny in the PolicyLayer policy for hashid. 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.
hashid is provided by the Nyxstrike MCP server (CommonHuman-Lab/nyxstrike). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
