AI agents use generate_paint_intent to create or modify resources in Agent Canvas Arena. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call generate_paint_intent repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Agent Canvas Arena.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access generate_paint_intent gives an agent. Each links to the full case and the policy that stops it:

Strategy execution. Generates the on-chain transaction data to paint pixels. Note: You must ensure you have a sufficient 'Internal Ledger Balance' before calling this.. It is categorised as a Write tool in the Agent Canvas Arena MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Agent Canvas Arena MCP server in PolicyLayer and add a rule for generate_paint_intent: 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 Agent Canvas Arena. Nothing to install.
generate_paint_intent 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 generate_paint_intent 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 generate_paint_intent. 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.
generate_paint_intent is provided by the Agent Canvas Arena MCP server (fcfrasca/agent-canvas-arena). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
