Generate ArchiMate diagrams in Mermaid or Draw.io format from elements and relationships
AI agents use generate_archimate_diagram to create or update resources in ArchiMate MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ArchiMate MCP Server environment.
This tool creates and generates new diagram artifacts based on input data. While it does not modify existing data or cause irreversible destruction, it does produce new persistent outputs (Mermaid or Draw.io diagrams). This qualifies as a Write operation—reversible content creation.
From the tool's definition Tool 'generate_archimate_diagram' creates diagrams in Mermaid or Draw.io format from provided elements and relationships. The description explicitly indicates diagram generation, which is a content creation operation.
Documented attack patterns abuse exactly the kind of access generate_archimate_diagram gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ArchiMate MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for generate_archimate_diagram:
{
"version": "1",
"default": "deny",
"tools": {
"generate_archimate_diagram": {
"limits": [
{
"counter": "generate_archimate_diagram_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}generate_archimate_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.

Generate ArchiMate diagrams in Mermaid or Draw.io format from elements and relationships. It is categorised as a Write tool in the ArchiMate MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the ArchiMate MCP Server MCP server in PolicyLayer and add a rule for generate_archimate_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 ArchiMate MCP Server. Nothing to install.
generate_archimate_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_archimate_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_archimate_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_archimate_diagram is provided by the ArchiMate MCP Server MCP server (rmranjit/mcp-archimate). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ArchiMate MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
