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

Generate an image from a text prompt. Supports multiple providers: gemini (Nano Banana, default), openai (DALL-E 3), xai (Aurora/Grok Imagine), stability (SD3.5), fal (Flux Pro). Useful for logos, diagrams, illustrations, concept art, and visual content. Users provide their own API key for the chosen provider.. It is categorised as a Write tool in the Alexandria 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 alexandria_generate_image. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Alexandria MCP server.
alexandria_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 alexandria_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 alexandria_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.
alexandria_generate_image is provided by the Alexandria MCP server (mcp-server-alexandria). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
