WHAT IT DOES

What solveSudoku does on API Ninjas

AI agents use solveSudoku 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
`body`	array	Yes
`width`	integer	Yes	Width of each box in the Sudoku grid. Must be between 2 and 4.
`height`	integer	Yes	Height of each box in the Sudoku grid. Must be between 2 and 4.

Parameters from the server's own tool schema.

RISK

Why solveSudoku is rated Medium

An AI agent can call solveSudoku 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.

RECOMMENDED RULE

The rule that runs solveSudoku 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 solveSudoku, this is the rule to start with:

solveSudoku Rate-limited

solveSudoku 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.
