promote_collection_environment
AI agents use promote_collection_environment to create or update resources in Vultr MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Vultr MCP environment.
The tool name suggests promoting or advancing an environment configuration within a collection, which constitutes a reversible modification of infrastructure state. Without a detailed description, it is classified as Write rather than higher-severity categories. The confidence is moderate due to the absence of a description and reliance on naming convention alone.
From the tool's definition Tool name 'promote_collection_environment' indicates modification of collection environment state (promotion implies advancing from one stage to another). Description is empty, limiting certainty.
Documented attack patterns abuse exactly the kind of access promote_collection_environment gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Vultr MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for promote_collection_environment:
{
"version": "1",
"default": "deny",
"tools": {
"promote_collection_environment": {
"limits": [
{
"counter": "promote_collection_environment_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}promote_collection_environment 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.
Free to start. No card required.
promote_collection_environment. It is categorised as a Write tool in the Vultr MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Vultr MCP server in PolicyLayer and add a rule for promote_collection_environment: 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 Vultr MCP. Nothing to install.
promote_collection_environment 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 promote_collection_environment 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 promote_collection_environment. 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.
promote_collection_environment is provided by the Vultr MCP server (rsp2k/mcp-vultr). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Vultr MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
