Cancel a build by buildId.
AI agents call travis_cancelBuild to permanently remove resources in Mcp Travis — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling a build is an irreversible action that terminates a running CI/CD pipeline. Once cancelled, the build cannot be resumed; it must be restarted from scratch. This constitutes an irreversible destructive operation with potentially high impact on deployment pipelines.

Attacks that exploit this kind of access
Cancel a build by buildId. It is categorised as a Destructive tool in the Mcp Travis MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp Travis MCP server in PolicyLayer and add a rule for travis_cancelBuild: 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 Mcp Travis. Nothing to install.
travis_cancelBuild 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 travis_cancelBuild 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 travis_cancelBuild. 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.
travis_cancelBuild is provided by the Mcp Travis MCP server (montana/mcp-travis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
