Oh Dear

Changelog for September 4th, 2026

MCP prepared for ChatGPT, expanded HTTP monitoring API docs, improved Arazzo workflows, and brand asset updates.

New #

  • Expanded the OpenAPI specification and API documentation with response body assertions and other previously missing HTTP uptime settings.
  • Updated the Arazzo specification with a complete real-world HTTP monitoring workflow: creating a monitor, verifying it, updating its name and response body assertions, and deleting it.
  • Expanded the Brand Assets page with additional icons, usage guidelines, and ready-to-use press copy.

Improvements #

  • Prepared the Oh Dear MCP server for ChatGPT plugin submission.
  • Monitor creation now skips unnecessary check enable/disable operations when the requested state is already set.
  • Updated the documentation for connecting the Oh Dear Slack bot to private channels.

Fixes #

  • Fixed the PWA manifest having an empty app name and incorrect icon paths.
  • Fixed a get_crawl_results MCP tool error when returning results grouped by type.
  • Added proper validation for third-party integration summaries, preventing overly long summaries from causing server errors.
