Console demo
See it in action.
01 — Open the hosted console with sample watches, live KPIs, and breaking counts — the same views your on-call team uses daily.
External schema monitoring
Production alerts. Before your stack breaks.
DriftGuard snapshots REST APIs and MCP tool catalogs on a schedule, classifies every change, and routes breaking diffs to Slack and PagerDuty — not after users find out.

Monitor the APIs and MCP servers your agents depend on
The watchtower
Catch drift before production does.
Vendor APIs and MCP tool catalogs change on their schedule — not yours. DriftGuard turns silent schema changes into classified, actionable alerts.
Watch fleet
Every dependency, one fleet view.
02 — REST APIs and MCP servers in a single watch list with status dots, sparkline history, and breaking counts at a glance.
Classified diffs
Breaking, warning, and info — not raw JSON noise.
03 — Required field removed pages on-call. Optional param added logs as warning. Description tweaks stay info.
MCP-native
Grounded in your agent stack.
04 — Track tools/list schema changes before Cursor agents break in production. Same watch model as REST OpenAPI.
Alert routing
Wires into the stack you already run.
05 — Slack, PagerDuty, webhooks, and Jira with breaking-only filters. MCP client for offline diff in Cursor.
