24 tools. 14 can modify or destroy data without limits.
3 destructive tools with no built-in limits. Policy required.
Last updated:
Destructive tools (delete_plan, delete_spec, delete_task) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (add_acceptance_criterion, add_task_log, create_plan) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.
Execute tools (start_server, stop_server) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.
delete_plan:
rules:
- action: deny Destructive tools should never be available to autonomous agents without human approval.
add_acceptance_criterion:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
list_criteria:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The Sdd server exposes 3 destructive tools including delete_plan, delete_spec, delete_task. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
The Sdd server has 9 write tools including add_acceptance_criterion, add_task_log, create_plan. 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.
24 tools across 4 categories: Destructive, Execute, Read, Write. 10 are read-only. 14 can modify, create, or delete data.
One line change. Instead of running the Sdd server directly, prefix it with Intercept: intercept -c sdd.yaml -- npx -y @@rafaelsouza-ai/mcp-server-sdd. Download a pre-built policy from policylayer.com/policies/sdd and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
