A monitoring tool for the MCP era.
MCPatrol is an Android app that watches MCP (Model Context Protocol) servers — the tool servers that AI agents connect to. A cloud prober checks every server you register around the clock; the app puts health, latency history, incidents, and change alerts on your phone.
It exists because MCP servers fail differently from websites. A web page is up or down. An MCP server can be "up" while a tool your agents depend on has quietly disappeared, changed its schema, or been joined by a new tool nobody reviewed. Uptime monitors don't see any of that. MCPatrol snapshots each server's full inventory — tools, resources, prompts — on every examination and diffs it, so change is a first-class alert alongside down.
Who builds it
MCPatrol is a product of Detent Point, LLC, an independent company founded by Keith Ramsey — a developer who runs MCP servers and wanted to know, from a phone, that they're behaving. It grew out of an operations console for exactly that job.
How it works
- Unknown values. If a value isn't known, the app shows a dash and says UNKNOWN. Latency, uptime, and MTTR are computed from recorded probe outcomes.
- Registry checks. Listing checks read each site's published sitemaps once a day with a descriptive User-Agent — a few XML fetches, no crawling of pages their robots.txt excludes. (How that works.)
- Your data. No advertising or analytics SDKs. Local mode keeps everything on your device. Account deletion is one button and removes everything, immediately. Details in the privacy policy.
The stack, briefly
The Android app is Kotlin and Jetpack Compose. The backend is ASP.NET Core on Azure Container Apps with PostgreSQL, probing on a fixed cadence and pushing over Firebase Cloud Messaging. A small bridge agent relays stdio MCP servers from your PC into the same estate.
