generate_image

Generate an AI image from a text prompt using Flux models. Returns an image URL. Models: flux-schnell (fast, $0.02), flux-dev (quality, $0.03), flux-pro (best, $0.05).

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

henry-ships/sparkforge Write Risk 2/5

// WHEN AI AGENTS USE THIS TOOL

AI agents use generate_image to create or modify resources in SparkForge. 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 GENERATE_IMAGE

Without a policy, an AI agent could call generate_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 SparkForge.

// RECOMMENDED POLICY

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

What does the generate_image tool do? +

Generate an AI image from a text prompt using Flux models. Returns an image URL. Models: flux-schnell (fast, $0.02), flux-dev (quality, $0.03), flux-pro (best, $0.05).. It is categorised as a Write tool in the SparkForge MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on generate_image? +

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

What risk level is generate_image? +

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

Can I rate-limit generate_image? +

Yes. Add a rate_limit block to the generate_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 generate_image completely? +

Set action: deny in the Intercept policy for generate_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 generate_image? +

generate_image is provided by the SparkForge MCP server (henry-ships/sparkforge). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
