37 tools. 9 can modify or destroy data without limits.
3 destructive tools with no built-in limits. Policy required.
Last updated:
Destructive tools (cancel_execution, delete_pipeline, delete_strategy) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (resume_execution, save_pipeline, save_strategy) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Execute tools (restart_stage, trigger_pipeline) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
cancel_execution:
rules:
- action: deny Destructive tools should never be available to autonomous agents without human approval.
resume_execution:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
evaluate_expression:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The Spinnaker server exposes 3 destructive tools including cancel_execution, delete_pipeline, delete_strategy. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
The Spinnaker server has 4 write tools including resume_execution, save_pipeline, save_strategy. Set rate limits in your policy file -- for example, rate_limit: 10/hour prevents an agent from making more than 10 modifications per hour. Intercept enforces this at the transport layer.
37 tools across 4 categories: Destructive, Execute, Read, Write. 28 are read-only. 9 can modify, create, or delete data.
One line change. Instead of running the Spinnaker server directly, prefix it with Intercept: intercept -c io-github-geiserx-spinnaker-mcp.yaml -- npx -y @spinnaker-mcp. Download a pre-built policy from policylayer.com/policies/io-github-geiserx-spinnaker-mcp and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
