Create a Technology layer element (Chapter 10). Use for nodes, devices, infrastructure, and physical elements.
AI agents use archimate_create_technology_element 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 new elements within an ArchiMate architecture model, which constitutes data creation and modification. While not destructive (elements can be edited or removed), it does permanently add structured data to the model repository. The Write category is appropriate because the operation is reversible (created elements can be modified or deleted by subsequent operations).
From the tool's definition Tool name and description indicate creation of Architecture model elements: 'Create a Technology layer element' and 'Create...infrastructure, and physical elements' represent irreversible model modifications to an ArchiMate repository.
Documented attack patterns abuse exactly the kind of access archimate_create_technology_element 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 archimate_create_technology_element:
{
"version": "1",
"default": "deny",
"tools": {
"archimate_create_technology_element": {
"limits": [
{
"counter": "archimate_create_technology_element_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} archimate_create_technology_element 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.

Create a Technology layer element (Chapter 10). Use for nodes, devices, infrastructure, and physical elements. 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 archimate_create_technology_element: 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.
archimate_create_technology_element 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 archimate_create_technology_element 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 archimate_create_technology_element. 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.
archimate_create_technology_element is provided by the ArchiMate MCP Server MCP server (thijs-hakkenberg/archimate-mcp). 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.
