Rotate a frame by 90, 180, or 270 degrees. Supports applying to all frames. Note: 90/270 rotation on non-square frames will swap width and height.
AI agents use rotate to create or update resources in Piskel MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Piskel MCP Server environment.
Rotation is a reversible geometric transformation that alters pixel art frames but does not delete, destroy, or permanently corrupt data. Users can rotate back to restore the original state. This is a classic Write operation—it modifies existing data in a recoverable manner. The transformation is deterministic and safe, making severity low. High confidence because the tool's purpose and reversibility are explicit.
From the tool's definition The tool 'rotate' modifies frame data by changing orientation (90, 180, or 270 degrees), which is a reversible transformation.
Documented attack patterns abuse exactly the kind of access rotate gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Piskel MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for rotate:
{
"version": "1",
"default": "deny",
"tools": {
"rotate": {
"limits": [
{
"counter": "rotate_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}rotate 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.

Rotate a frame by 90, 180, or 270 degrees. Supports applying to all frames. Note: 90/270 rotation on non-square frames will swap width and height. It is categorised as a Write tool in the Piskel MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Piskel MCP Server MCP server in PolicyLayer and add a rule for rotate: 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 Piskel MCP Server. Nothing to install.
rotate 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 rotate 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 rotate. 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.
rotate is provided by the Piskel MCP Server MCP server (yafeiaa/piskel-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Piskel MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
