Cancel a pending operation
AI agents call cancel-operation to permanently remove resources in RSK MCP Server - Rootstock Blockchain Tools — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling a pending blockchain operation is irreversible — once a cancel transaction is submitted on-chain, the original operation cannot be reinstated. This is analogous to overwriting or voiding state that cannot be undone, placing it in the Destructive category.

Attacks that exploit this kind of access
Cancel a pending operation. It is categorised as a Destructive tool in the RSK MCP Server - Rootstock Blockchain Tools MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the RSK MCP Server - Rootstock Blockchain Tools MCP server in PolicyLayer and add a rule for cancel-operation: 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 RSK MCP Server - Rootstock Blockchain Tools. Nothing to install.
cancel-operation 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 cancel-operation 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 cancel-operation. 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.
cancel-operation is provided by the RSK MCP Server - Rootstock Blockchain Tools MCP server (rsksmart/rsk-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
