AI agents use create_placement_group to create or update resources in Linode MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Linode MCP Server environment.
This tool creates a new cloud infrastructure resource (a placement group). It modifies the user's infrastructure state but does not delete, execute arbitrary code, or move funds. The action is reversible, making it a Write operation rather than Destructive.
From the tool's definition Tool name 'create_placement_group' and description 'Create a new placement group' indicate resource creation. Placement groups are infrastructure configuration objects that group Linode instances together (typically for performance or locality purposes).
Documented attack patterns abuse exactly the kind of access create_placement_group gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Linode MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_placement_group:
{
"version": "1",
"default": "deny",
"tools": {
"create_placement_group": {
"limits": [
{
"counter": "create_placement_group_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_placement_group 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.
Create a new placement group. It is categorised as a Write tool in the Linode MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Linode MCP Server MCP server in PolicyLayer and add a rule for create_placement_group: 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 Linode MCP Server. Nothing to install.
create_placement_group 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 create_placement_group 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 create_placement_group. 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.
create_placement_group is provided by the Linode MCP Server MCP server (takashito/linode-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Linode MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
