Why tunnels_revoke is rated Critical
Revoking a tunnel is an irreversible action that permanently invalidates or terminates the tunnel resource. Like session revocation, this cannot be undone — the tunnel must be recreated. The sibling tool 'account_sessions_revoke' confirms that 'revoke' on this server means permanent invalidation. Severity is high because revoking active tunnels could disrupt running services or applications depending on them.
From the tool's definition 'tunnels_revoke' — 'revoke' indicates an irreversible action that terminates/invalidates a tunnel, analogous to other revoke operations on this server (e.g., account_sessions_revoke) which permanently invalidate access
Attacks that exploit this kind of access
The rule that runs tunnels_revoke safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Appaloft, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For tunnels_revoke, this is the rule to start with:
tunnels_revoke is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Appaloft, apply this rule, and every tunnels_revoke call is checked against it from then on.

Register the Appaloft MCP server in PolicyLayer and add a rule for tunnels_revoke: 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 Appaloft. Nothing to install.
tunnels_revoke 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 tunnels_revoke 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 tunnels_revoke. 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.
tunnels_revoke is provided by the Appaloft MCP server (@appaloft/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
