- Tasks

- Verdict
- Pick it to triage production errors and check feature flags or analytics from your editor; start with readonly=true and pin the project before allowing writes.
- Permissions
- Reads and writes across your PostHog project with your account's access: product analytics and HogQL/SQL queries, error tracking (stack traces, issue status), feature flags, experiments, surveys, CDP destinations and more. Add `readonly=true` to drop all write tools; pin to one project with x-posthog-project-id.
- Credentials
- PostHog account via OAuth (routes to US or EU automatically), or a personal API key with the MCP Server preset as a Bearer header.
- Maintenance
- Hosted remote server (free to call; some AI-powered tools bill as PostHog AI spend); source in PostHog/posthog services/mcp, last commit 2026-10-24. The old PostHog/mcp repo is archived.
- License
- MIT (services/mcp package; hosted service under PostHog terms)
- Install
