Revoke an access token by ID.
AI agents call revoke_access_token to permanently remove resources in S2 StreamStore MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Revoking an access token is an irreversible action — once revoked, the token can no longer be used and cannot be restored. This permanently destroys authentication credentials, potentially breaking integrations, automated workflows, or agent access that depended on that token. The irreversible nature places it in the Destructive category with high severity due to the blast radius of losing access credentials.

Attacks that exploit this kind of access
Revoke an access token by ID. It is categorised as a Destructive tool in the S2 StreamStore MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the S2 StreamStore MCP Server MCP server in PolicyLayer and add a rule for revoke_access_token: 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 S2 StreamStore MCP Server. Nothing to install.
revoke_access_token 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 revoke_access_token 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 revoke_access_token. 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.
revoke_access_token is provided by the S2 StreamStore MCP Server MCP server (s2-streamstore/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
revoke_access_token is one line of S2 StreamStore MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
