Part of the Prompt To Asset MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents use asset_generate_og_image to create or modify resources in Prompt To Asset. 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.

// WHY ENFORCE A POLICY ON ASSET_GENERATE_OG_IMAGE

Without a policy, an AI agent could call asset_generate_og_image repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Prompt To Asset.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the asset_generate_og_image tool do? +

Render a 1200×630 OG image via Satori template (deterministic typography, no diffusion). Default mode=api renders server-side without any API key. external_prompt_only is only meaningful when with_background_image is set. inline_svg is not supported (web-font loading + precise text layout beyond LLM reach).. It is categorised as a Write tool in the Prompt To Asset MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on asset_generate_og_image? +

Add a rule in your Intercept YAML policy under the tools section for asset_generate_og_image. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Prompt To Asset MCP server.

What risk level is asset_generate_og_image? +

asset_generate_og_image is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit asset_generate_og_image? +

Yes. Add a rate_limit block to the asset_generate_og_image rule in your Intercept 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.

How do I block asset_generate_og_image completely? +

Set action: deny in the Intercept policy for asset_generate_og_image. 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.

What MCP server provides asset_generate_og_image? +

asset_generate_og_image is provided by the Prompt To Asset MCP server (prompt-to-asset). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
