What cancel_execution does on Huly
AI agents invoke cancel_execution to trigger actions in Huly. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why cancel_execution is rated High
The tool cancels an in-progress process execution by modifying its status. The description is truncated and incomplete, which lowers confidence. Cancelling an execution is a state-change operation on a running process — it's closest to Execute (modifying execution state) or Write (updating a status field). Since it affects a running process and terminates it, Execute is the most appropriate category.

Attacks that exploit this kind of access
The rule that runs cancel_execution safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Huly, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For cancel_execution, this is the rule to start with:
cancel_execution stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Huly, apply this rule, and every cancel_execution call is checked against it from then on.
Questions about cancel_execution
Cancel an in-flight Process execution by setting its status to. It is categorised as a Execute tool in the Huly MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Huly MCP server in PolicyLayer and add a rule for cancel_execution: 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 Huly. Nothing to install.
cancel_execution is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the cancel_execution 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_execution. 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_execution is provided by the Huly MCP server (dugynoo/huly-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
