AI agents use create_team to create or update resources in eToro MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your eToro MCP Server environment.
This tool creates a new organizational entity (team) within the user's account, which is a write operation that modifies account structure. The severity is medium because creating teams could lead to organizational confusion or resource allocation issues if misused by an AI agent, but the action is reversible and does not involve financial transactions, irreversible deletion, or code execution.
From the tool's definition Tool name 'create_team' and description 'Create a new Team under your account' indicate data creation. The action is reversible (teams can typically be deleted), and has no financial impact or destructive consequences.
Documented attack patterns abuse exactly the kind of access create_team gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and eToro MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_team:
{
"version": "1",
"default": "deny",
"tools": {
"create_team": {
"limits": [
{
"counter": "create_team_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_team 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 new Team under your account. It is categorised as a Write tool in the eToro MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the eToro MCP Server MCP server in PolicyLayer and add a rule for create_team: 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 eToro MCP Server. Nothing to install.
create_team 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_team 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_team. 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_team is provided by the eToro MCP Server MCP server (shlomico-tr/etoroportfoliomcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from eToro MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
