AI agents call linear_removeUserFromTeam to permanently remove resources in Linear — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a user from a team revokes their access and membership. While the user still exists, the removal of team membership is typically an impactful and potentially irreversible action (depending on the system's audit trail), with high blast radius if misused by an AI agent — it could remove the wrong user and disrupt their workflow and access.
From the tool's definition 'Remove a user from a team' — removes membership, which is an irreversible organizational action (the user loses access and team membership)
Documented attack patterns abuse exactly the kind of access linear_removeUserFromTeam gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Linear, and nothing reaches the server without passing your rules. This is the rule we recommend for linear_removeUserFromTeam:
{
"version": "1",
"default": "deny",
"hide": [
"linear_removeUserFromTeam"
]
}linear_removeUserFromTeam disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Yes. Add a rate_limit block to the linear_removeUserFromTeam 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 linear_removeUserFromTeam. 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.
linear_removeUserFromTeam is provided by the Linear MCP server (tacticlaunch/mcp-linear). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
