Oh Dear

Changelog for August 28th, 2026

New MCP tools, consecutive-failure Sitemap alerts, and improved Lighthouse checks.

New #

  • Expanded our MCP server with new tools for:
    • Downtime, check summaries, and domain intelligence.
    • Maintenance windows and check state management.
    • Status page updates and notification destinations.
    • Scheduled tasks, tags, Broken Links, Application Health, and account management.
  • Added a consecutive failures threshold for Sitemap notifications, allowing you to choose how many consecutive failures should occur before being notified.
  • Added an in-app warning for Slack connections that will stop working in November, giving affected teams time to reconnect.

Improvements #

  • AI wizard placeholder monitors no longer count toward your monitor limit or usage.
  • Scheduled Task history now leaves a marker when older pings are pruned, making gaps in historical data clearer.
  • Scheduled Task pings are now handled correctly even when they arrive out of order.
  • Improved our MCP tools with clearer titles and behaviour hints.
  • Improved the get_uptime_statistics MCP tool to return actual uptime percentages instead of response timings.
  • Added documentation for connecting to the Oh Dear MCP server from clients other than Claude.
  • Corrected our affiliate commission terms to 25% for the first 12 months.
  • Long-time members can now see their legacy pricing directly on the plan chooser.

Security #

  • Changing your password now invalidates existing sessions and password reset tokens.
  • Strengthened access controls for the new MCP write tools.

Fixes #

  • Fixed Lighthouse checks running every other day instead of daily.
  • Fixed Lighthouse history charts breaking when certain browser extensions are active.
  • Fixed invoice ordering so invoices are sorted using their actual creation date in Stripe.
  • Fixed a server error when changing a team's owner.
  • Fixed double-encoded HTML entities appearing in inputs across the app after saving.
  • Fixed a server error when accessing a status page domain route with an invalid hostname.
  • Fixed the OG loyalty discount not being reapplied when a long-time member restarted an expired subscription.
