What is Oh Dear?

Oh Dear turns its entire monitoring surface into an MCP API, making the product fully AI-agent accessible.

Oh Dear is an uptime and site monitoring product that has spent the last month systematically wiring its full feature set into a Model Context Protocol server. The August 28 release added MCP tools for downtime data, check summaries, domain intelligence, maintenance windows, check state, status page management, notification destinations, scheduled tasks, tags, Broken Links, Application Health, and account management—covering virtually the entire product in one release. The following week, API token scoping was hardened specifically to secure MCP tool access.

What is ESPHome?

ESPHome 2026.9.0 ships template climate component, OTA encryption with API key, and ESP-NOW for ESP32-P4

ESPHome 2026.9.0 is out, capping a beta cycle that added a template climate component (a long-requested flexible HVAC control primitive), OTA encryption keyed to the device's API key (hardening the update path), and ESP-NOW over hosted shim for the ESP32-P4. The beta cycle also included a systematic RAM allocation safety pass across the codebase — heap exhaustion now returns an error instead of panicking. Monthly releases continue landing at a consistent pace.

Oh Dear turns its entire monitoring surface into an MCP API, making the product fully AI-agent accessible.

◆ Current state

Oh Dear is an uptime and site monitoring product that has spent the last month systematically wiring its full feature set into a Model Context Protocol server. The August 28 release added MCP tools for downtime data, check summaries, domain intelligence, maintenance windows, check state, status page management, notification destinations, scheduled tasks, tags, Broken Links, Application Health, and account management—covering virtually the entire product in one release. The following week, API token scoping was hardened specifically to secure MCP tool access.

◆ Where it's heading

Oh Dear is deliberately building an AI-first monitoring interface, not as a side project but as a primary access layer. The sequence—ship comprehensive MCP coverage, immediately harden authorization around it—suggests they're treating the MCP server with the same production seriousness as their REST API. The internal migration from Prism to Laravel AI SDK for their AI monitoring features and the addition of automated prompt evaluations show the same investment on the engineering side. JSON request body support in HTTP checks and Arazzo specification updates round out a broader API-maturity push.

◆ Prediction

Expect Oh Dear to publish MCP server documentation or a dedicated landing page as the natural next step given coverage breadth. AI-generated downtime summaries or weekly digest features inside the product UI are a logical extension of the agent-accessible data layer they've now built.

ESPHome 2026.9.0 ships template climate component, OTA encryption with API key, and ESP-NOW for ESP32-P4

◆ Current state

ESPHome 2026.9.0 is out, capping a beta cycle that added a template climate component (a long-requested flexible HVAC control primitive), OTA encryption keyed to the device's API key (hardening the update path), and ESP-NOW over hosted shim for the ESP32-P4. The beta cycle also included a systematic RAM allocation safety pass across the codebase — heap exhaustion now returns an error instead of panicking. Monthly releases continue landing at a consistent pace.

◆ Where it's heading

ESPHome is expanding in two directions simultaneously: broader hardware support (ESP32-P4, BK72xx BLE, new platform components) and more robust runtime behavior (RAMAllocator pattern, use-after-free fixes, better BLE-WiFi coexistence). The template climate component is the most user-visible addition — it brings custom HVAC logic into ESPHome's declarative model, reducing the need for external Home Assistant automations. Audio stack (i2s, resampler, mixer) reliability is also a consistent focus.

◆ Prediction

The 2026.10.0 cycle will likely continue the RAMAllocator pattern across remaining allocating code paths and add more ESP32-P4-specific features. Audio (voice assistants, speakers) will stay a top area given the ongoing i2s reliability work.
