What password_entropy does on Gateway
AI agents call password_entropy to retrieve information from Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
digits | boolean | — | Include digits 0-9 (10) |
length | integer | Yes | Password length in characters |
symbols | boolean | — | Include symbols (~32) |
lowercase | boolean | — | Include lowercase a-z (26) |
uppercase | boolean | — | Include uppercase A-Z (26) |
charset_size | integer | — | Explicit character pool size (overrides flags below) |
Parameters from the server's own tool schema.
Why password_entropy is rated Low
This is a purely analytical utility that reads input parameters (password length, character set composition) and returns computational results. It performs no side effects, does not interact with external systems, does not execute code or commands, and does not modify or destroy any data. The output is informational only—a strength assessment. This is a low-severity read operation.
From the tool's definition Tool is a 'Password Entropy Calculator' that computes 'Entropy bits and strength from password length and character pool.' It takes password characteristics as input and returns calculated metrics (entropy, strength).
Attacks that exploit this kind of access
The rule that runs password_entropy safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Gateway, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For password_entropy, this is the rule to start with:
password_entropy 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 Gateway, apply this rule, and every password_entropy call is checked against it from then on.
Questions about password_entropy
Password Entropy Calculator — Entropy bits and strength from password length and character pool. It is categorised as a Read tool in the Gateway MCP Server, which means it retrieves data without modifying state.
password_entropy accepts 6 parameters: digits, length, symbols, lowercase, uppercase, charset_size. Required: length. The full parameter table on this page comes from the server's own tool schema.
Register the Gateway MCP server in PolicyLayer and add a rule for password_entropy: 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 Gateway. Nothing to install.
password_entropy 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 password_entropy 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 password_entropy. 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.
password_entropy is provided by the Gateway MCP server (https://wingmanprotocol.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
