We've detected the same error happening again today. Some MCP connections would not connect between 19:29 and 20:39 UTC. We've rolled back to a known good version as soon as we detected the incident.

Due to elevated and extensive usage from our customers, we're actively migrating our MCP to a new architecture in the upcoming days, which should resolve both the existing problems and improve our downtime detection capabilities.

Current MCP connection is stabilized.

We've identified the cause and rolled back to a stable release. Looking into how to fix the update to avoid this.

PostHog MCP is not connecting to coding agents and IDEs, including but not limited to (Cursor, Claude, Claude Code, Codex, VS Code)
