Generate images with MiniMax. If no output path is provided, images are saved to the default output directory (e.g. ./mmx_image) and their file paths are returned.
AI agents use mmx_image_generate to create or update resources in Mmx — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mmx environment.
This tool creates new image files as output, modifying the filesystem and generating new data. This is a Write operation because it produces persistent changes (file creation) that are reversible (files can be deleted). It does not execute arbitrary code, destroy data irreversibly, or move money, making Write the appropriate category.
From the tool's definition Tool description states 'Generate images' and 'images are saved to the default output directory', indicating creation of new files/data with side effects.
Documented attack patterns abuse exactly the kind of access mmx_image_generate gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mmx, and nothing reaches the server without passing your rules. This is the rule we recommend for mmx_image_generate:
{
"version": "1",
"default": "deny",
"tools": {
"mmx_image_generate": {
"limits": [
{
"counter": "mmx_image_generate_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}mmx_image_generate stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Generate images with MiniMax. If no output path is provided, images are saved to the default output directory (e.g. ./mmx_image) and their file paths are returned. It is categorised as a Write tool in the Mmx MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mmx MCP server in PolicyLayer and add a rule for mmx_image_generate: 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 Mmx. Nothing to install.
mmx_image_generate 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 mmx_image_generate 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 mmx_image_generate. 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.
mmx_image_generate is provided by the Mmx MCP server (zth0828/mmx-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
