使用Seedream 4.0【批量生成多张图像】（组图生成）。当用户要求生成2张或更多图片时使用此工具。支持3种输入类型：文生组图、单图生组图、多图生组图。最多可生成15张图片
AI agents use seedream_sequential_generation to create or update resources in Seedream 4 0 MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Seedream 4 0 MCP Server environment.
This tool generates and stores multiple images (up to 15) using the Seedream 4.0 API with automatic cloud storage integration. It creates new artifacts and writes them to cloud storage, making it a Write operation. No destructive, financial, or code execution semantics are present.
From the tool's definition 批量生成多张图像 (batch generate multiple images), 最多可生成15张图片 (up to 15 images can be generated), supports text-to-image, single image to multiple images, multi-image to multiple images
Documented attack patterns abuse exactly the kind of access seedream_sequential_generation gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Seedream 4 0 MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for seedream_sequential_generation:
{
"version": "1",
"default": "deny",
"tools": {
"seedream_sequential_generation": {
"limits": [
{
"counter": "seedream_sequential_generation_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}seedream_sequential_generation 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.

使用Seedream 4.0【批量生成多张图像】（组图生成）。当用户要求生成2张或更多图片时使用此工具。支持3种输入类型：文生组图、单图生组图、多图生组图。最多可生成15张图片. It is categorised as a Write tool in the Seedream 4 0 MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Seedream 4 0 MCP Server MCP server in PolicyLayer and add a rule for seedream_sequential_generation: 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 Seedream 4 0 MCP Server. Nothing to install.
seedream_sequential_generation 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 seedream_sequential_generation 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 seedream_sequential_generation. 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.
seedream_sequential_generation is provided by the Seedream 4 0 MCP Server MCP server (joeseesun/seedream_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Seedream 4 0 MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
