Revokes the given invitation. Revoking an invitation will prevent the user from using the invitation link that was sent to them. However, it doesn't prevent the user from signing up if they follow the sign up flow. Only active (i.e. non-revoked) invitations can be revoked.

Part of the Clerk MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents may call RevokeInvitation to permanently remove or destroy resources in Clerk. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call RevokeInvitation in a loop, permanently destroying resources in Clerk. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.
Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

Revokes the given invitation. Revoking an invitation will prevent the user from using the invitation link that was sent to them. However, it doesn't prevent the user from signing up if they follow the sign up flow. Only active (i.e. non-revoked) invitations can be revoked.. It is categorised as a Destructive tool in the Clerk MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Add a rule in your Intercept YAML policy under the tools section for RevokeInvitation. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Clerk MCP server.
RevokeInvitation 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 RevokeInvitation rule in your Intercept 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 Intercept policy for RevokeInvitation. 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.
RevokeInvitation is provided by the Clerk MCP server (@clerk/clerk-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Open source. One binary. Zero dependencies.
