Remove a membership from a project.
AI agents call remove_membership to permanently remove resources in Redmine — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a membership is an irreversible action that revokes a user's access to a project. While a membership could potentially be re-added, the removal itself is a destructive operation that immediately cuts off access. The blast radius is high because an AI agent could inadvertently remove critical project members, disrupting project access and collaboration.

Attacks that exploit this kind of access
Remove a membership from a project. It is categorised as a Destructive tool in the Redmine MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Redmine MCP server in PolicyLayer and add a rule for remove_membership: 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 Redmine. Nothing to install.
remove_membership is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the remove_membership 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 remove_membership. 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.
remove_membership is provided by the Redmine MCP server (yenpu/redmine-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
