当用户的核心意图是【绘制、画出、创建、生成】一个【图表、架构图、流程图、原型图、产品设计所需的各种图表】时，调用此工具。它能生成draw.io文件、HTML原型、svg图表等。提示，如果用户需要生成svg图表，文件生成后，务必告诉用户可以通过 https://www.jyshare.com/more/svgeditor/ 网站对刚才生成的文件进行编辑修改。
AI agents use generate_diagram to create or update resources in AI Diagram & Prototype Generator — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AI Diagram & Prototype Generator environment.
This tool creates new data artifacts (diagrams, prototypes, charts) but does not execute arbitrary code, delete data irreversibly, move money, or trigger destructive operations. Users can regenerate or modify outputs, making changes reversible.
From the tool's definition Tool description states it can 'generate draw.io files, HTML prototypes, svg charts' (生成draw.io文件、HTML原型、svg图表等). The verbs 'generate' (生成) and 'create' (创建) indicate content creation.
Documented attack patterns abuse exactly the kind of access generate_diagram gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AI Diagram & Prototype Generator, and nothing reaches the server without passing your rules. This is the rule we recommend for generate_diagram:
{
"version": "1",
"default": "deny",
"tools": {
"generate_diagram": {
"limits": [
{
"counter": "generate_diagram_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}generate_diagram 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.

It is categorised as a Write tool in the AI Diagram & Prototype Generator MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the AI Diagram & Prototype Generator MCP server in PolicyLayer and add a rule for generate_diagram: 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 AI Diagram & Prototype Generator. Nothing to install.
generate_diagram 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 generate_diagram 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 generate_diagram. 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.
generate_diagram is provided by the AI Diagram & Prototype Generator MCP server (simonutd/ai-diagram-prototype-generator-mcp-server-). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
