AI agents use photopea_add_text to create or modify resources in Photopea. 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 photopea_add_text 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 Photopea.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access photopea_add_text gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Add a new text layer to the active document at the specified position. The text layer becomes the active layer. Use paragraphBounds to create a text box with word wrapping, or omit for point text. Use load_font to add custom fonts, and list_fonts to find available font names.. It is categorised as a Write tool in the Photopea MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Photopea MCP server in PolicyLayer and add a rule for photopea_add_text: 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 Photopea. Nothing to install.
photopea_add_text 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 photopea_add_text 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 photopea_add_text. 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.
photopea_add_text is provided by the Photopea MCP server (photopea-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
