Part of the Mcp Nanobanana Pro MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use nanobanana_generate_image to create or modify resources in Mcp Nanobanana Pro. 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 nanobanana_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 Mcp Nanobanana Pro.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Generate an AI image from a text prompt using Google's Nano Banana model. This creates high-quality images from detailed text descriptions. The more descriptive your prompt, the better the results. Use this when: - You want to generate a new image from scratch - You have a detailed description of the desired image - You need photorealistic or artistic image generation Prompt writing tips: - Include: Main subject + Atmosphere + Lighting + Camera/Lens + Quality keywords - Example: "Urban career woman, backlit sunlight, film grain, orange-gold tones, hopeful dawn" Returns: Task ID, trace ID, and generated image URL. . It is categorised as a Write tool in the Mcp Nanobanana Pro MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for nanobanana_generate_image. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Mcp Nanobanana Pro MCP server.
nanobanana_generate_image 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 nanobanana_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.
Set action: deny in the Intercept policy for nanobanana_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.
nanobanana_generate_image is provided by the Mcp Nanobanana Pro MCP server (acedatacloud-mcp/mcp-nanobanana-pro). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
