Add an MCP watch
Paste your MCP HTTP/SSE endpoint or pick from onboarding templates.
At agent speed, drift in production is inevitable
Tool catalogs evolve faster than your deploy cadence. Runtime monitoring closes the gap CI diff tools can't.
✕ Without DriftGuard
- Tool removed silently — agents fail mid-task
- inputSchema tightens without a deploy
- Discover breaks from user reports or error logs
- Manual diff of MCP responses after incidents
✓ With DriftGuard
- Scheduled
tools/listsnapshots - Breaking vs warning vs info on every diff
- Slack / PagerDuty on breaking changes only
- Import servers from

Quickstart
Three steps from MCP URL to classified drift alerts.
02
Baseline the catalog
First check stores tools, resources, and prompts as the reference snapshot.
03
Alert on breaking
Wire Slack or webhooks — removed tools and required-field additions page you.
01
Ship agents faster without fear of silent tool regressions.
02
Reduce agent incident time with diffs before user impact.
03
Mix MCP and REST watches in one console fleet view.
04
Offline diff via open-source MCP client in Cursor.
