WHAT IT DOES

What atbash_cipher does on GadgetHumans API Hub

AI agents invoke atbash_cipher to trigger actions in GadgetHumans API Hub. 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.

RISK

Why atbash_cipher is rated High

The tool performs a text transformation operation (cipher encoding/decoding) rather than simply retrieving data. It processes input text and produces transformed output, making it an execution of a cryptographic algorithm. Severity is low as it only manipulates text with no external side effects or data persistence.

RECOMMENDED RULE

The rule that runs atbash_cipher safely

PolicyLayer is an MCP gateway: it sits between your AI agents and GadgetHumans API Hub, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For atbash_cipher, this is the rule to start with:

atbash_cipher Rate-limited

atbash_cipher 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.

          "counter": "atbash_cipher_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect GadgetHumans API Hub, apply this rule, and every atbash_cipher call is checked against it from then on.

FAQ

Questions about atbash_cipher

What does the atbash_cipher tool do? +

Apply the Atbash cipher (reverse alphabet substitution) to text. It is categorised as a Execute tool in the GadgetHumans API Hub MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on atbash_cipher? +

Register the GadgetHumans API Hub MCP server in PolicyLayer and add a rule for atbash_cipher: 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 GadgetHumans API Hub. Nothing to install.

What risk level is atbash_cipher? +

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

Can I rate-limit atbash_cipher? +

Yes. Add a rate_limit block to the atbash_cipher 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 atbash_cipher completely? +

Set action: deny in the PolicyLayer policy for atbash_cipher. 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 atbash_cipher? +

atbash_cipher is provided by the GadgetHumans API Hub MCP server (pypi:gadgethumans-api-hub-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
