What's new in Vantaj

Product updates, new features, and improvements shipped every week.

v1.7.1featureAugust 7, 2026

MCP & API: Pause, Resume & Maintenance Windows

  • New MCP tools: pause_monitor, resume_monitor, and create_maintenance_window - let an AI assistant or deploy pipeline silence alerts before planned work
  • REST API: pause and resume monitors via PATCH /v1/monitors/:id with { "paused": true/false }
  • REST API: POST /v1/maintenance-windows creates one-time maintenance windows (alerts suppressed, checks keep running)
  • MCP tool count grows to 13 - still reads and additive writes only, no deletes
v1.7.0featureJuly 10, 2026

MCP Server

  • Hosted MCP (Model Context Protocol) server at api.vantaj.co/mcp - connect Claude, Claude Code, Cursor, or any MCP client to your monitoring
  • 10 tools: list/create/update monitors (including inverted checks), heartbeats, incidents, domains, status pages, and projects
  • Authenticates with your existing API keys - scopes, plan limits, and rate limits apply exactly as on the REST API
  • Safe by design: reads and additive writes only - no delete operations exposed to AI clients
  • Setup guide for every client at vantaj.co/docs/mcp-server
v1.6.0featureJuly 2, 2026

One-Click Migration & Inverted Checks

  • One-click importers for UptimeRobot, Pingdom, StatusCake, and Better Stack - paste a read-only API key and your monitors, keyword checks, and heartbeats come over in seconds
  • Uptime Kuma import - upload a backup file, parsed entirely in your browser; upside-down monitors map to inverted checks
  • Bulk CSV import with a downloadable template - works with any provider that can export a spreadsheet
  • Inverted checks (exposure monitoring) - alert when a target that should stay down becomes reachable: internal panels, closed ports, retired endpoints
  • HTTP QUERY method support for request monitors
  • Status pages: larger, more readable text throughout; incident severity shown by color
  • Inverted flag available via the REST API on monitor create and update
v1.5.0featureJune 22, 2026

Public REST API & Alert Policies

  • Public REST API (api.vantaj.co) - full CRUD for monitors, heartbeats, domains, status pages, and incidents
  • API key management with SHA-256 hashing (vtj_live_ format, shown once)
  • Scoped permissions: granular read/write per resource
  • Rate limiting via Durable Objects - per-key daily quotas and burst control
  • Alert policies with multi-step escalation (delay between steps, multiple channels per policy)
  • Interactive API docs at api.vantaj.co/docs (OpenAPI / Zod-driven)
