AI agents invoke versions_publish_draft to trigger actions in Piwik PRO MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
The tool name suggests it publishes a draft version, which is an irreversible or significant state-change operation (making a draft live). In a tag management/analytics context, publishing a draft can affect live tracking configurations across all users. This is most likely an Execute-level action (triggering an external operation/state change).

Documented attack patterns abuse exactly the kind of access versions_publish_draft gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Piwik PRO MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for versions_publish_draft:
{
"version": "1",
"default": "deny",
"tools": {
"versions_publish_draft": {
"limits": [
{
"counter": "versions_publish_draft_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} versions_publish_draft stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
