What generatePassword does on API Ninjas
AI agents use generatePassword to create or update resources in API Ninjas, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your API Ninjas environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
length | integer | — | Length of password in characters. If not set, a default value of 16 is used. |
exclude_numbers | boolean | — | Whether to exclude numbers from the password. Must be either true or false. If not set, a default value of false will be used. |
exclude_special_chars | boolean | — | Whether to exclude special characters(!@#$%^&*()) from the password. Must be either true or false. If not set, a default value of false will be used. |
Parameters from the server's own tool schema.
Why generatePassword is rated Medium
An AI agent can call generatePassword faster than any human can review: one bad instruction and it creates or modifies resources in API Ninjas by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
The rule that runs generatePassword safely
PolicyLayer is an MCP gateway: it sits between your AI agents and API Ninjas, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For generatePassword, this is the rule to start with:
generatePassword stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect API Ninjas, apply this rule, and every generatePassword call is checked against it from then on.
Questions about generatePassword
Generates one random password of the requested length, optionally excluding numbers or special characters. Defaults to 16 characters when no length is given. It is categorised as a Write tool in the API Ninjas MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
generatePassword accepts 3 parameters: length, exclude_numbers, exclude_special_chars. The full parameter table on this page comes from the server's own tool schema.
Register the API Ninjas MCP server in PolicyLayer and add a rule for generatePassword: 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 API Ninjas. Nothing to install.
generatePassword is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the generatePassword 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 generatePassword. 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.
generatePassword is provided by the API Ninjas MCP server (https://mcp.api-ninjas.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
