AI agents use transaction_commit to create or update resources in AutoCAD MCP Pro — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AutoCAD MCP Pro environment.
Committing a transaction finalizes and persists all pending changes made during a transaction to the CAD drawing. This is a Write operation as it makes changes permanent/reversible (the drawing can still be edited again). Severity is medium because misuse could prematurely commit unintended changes to the drawing, though the drawing itself isn't destroyed and changes could potentially be undone.
From the tool's definition Commit the current transaction
Documented attack patterns abuse exactly the kind of access transaction_commit gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AutoCAD MCP Pro, and nothing reaches the server without passing your rules. This is the rule we recommend for transaction_commit:
{
"version": "1",
"default": "deny",
"tools": {
"transaction_commit": {
"limits": [
{
"counter": "transaction_commit_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}transaction_commit 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.

Commit the current transaction. It is categorised as a Write tool in the AutoCAD MCP Pro MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the AutoCAD MCP Pro MCP server in PolicyLayer and add a rule for transaction_commit: 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 AutoCAD MCP Pro. Nothing to install.
transaction_commit 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 transaction_commit 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 transaction_commit. 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.
transaction_commit is provided by the AutoCAD MCP Pro MCP server (u-c4n/autocad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from AutoCAD MCP Pro, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
