PostHog Code Inbox signal sources

Inbox uses signal sources to find work worth investigating. A signal can be a production error, a support conversation, a session replay pattern, or an issue from an external tracker.

Configure sources

  1. Open Inbox in PostHog Code.
  2. Click the Settings icon or open the Signal Sources tab.
  3. Toggle the sources you want to enable.
  4. Follow the authentication prompts for external services.
MCP is handled for you
You don't need to configure MCP servers for Inbox sources manually. Once your repository is connected in PostHog Code, research tasks can run automatically.

PostHog sources

These sources are available when the matching PostHog product has data in your project.

External sources

External sources pull issue context into the same Inbox queue as your product signals.

SourceWhat Inbox readsWhat Inbox does
GitHub IssuesNew issues in connected repositoriesStarts a research task to find related code and decide whether a fix is possible
LinearIssue title, description, labels, and linked contextSearches the codebase and keeps the report tied to the original issue
ZendeskCustomer support ticket contextTurns actionable bug reports into researched implementation work

What happens next

When a signal arrives, Inbox creates a report and starts research if the source is enabled. The research agent connects the signal to the codebase, checks user impact, and marks the report as Actionable when a code fix is possible.

From there, you can:

  • Review the report in Inbox
  • Ask for more research
  • Let an implementation agent open a PR
  • Audit the agent log to see exactly what it read and why
