使用Seedream 4.0将多张图像融合生成【单张】新图像（多图融合）。需要提供2-10张输入图片。如果需要生成多张融合结果，请使用 seedream_sequential_generation 工具
AI agents use seedream_multi_image_fusion 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 creates new content (a fused image) by combining multiple input images. It is a generative/write operation that produces a new artifact in cloud storage. It does not execute code, delete data, or involve financial transactions. Severity is medium because it consumes API credits and generates/uploads content, but has limited blast radius.
From the tool's definition 将多张图像融合生成【单张】新图像（多图融合）— fuses multiple images to generate a single new image
Documented attack patterns abuse exactly the kind of access seedream_multi_image_fusion 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_multi_image_fusion:
{
"version": "1",
"default": "deny",
"tools": {
"seedream_multi_image_fusion": {
"limits": [
{
"counter": "seedream_multi_image_fusion_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}seedream_multi_image_fusion 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将多张图像融合生成【单张】新图像（多图融合）。需要提供2-10张输入图片。如果需要生成多张融合结果，请使用 seedream_sequential_generation 工具. 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_multi_image_fusion: 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_multi_image_fusion 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_multi_image_fusion 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_multi_image_fusion. 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_multi_image_fusion 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.
Free to start. No card required.
