PPostHog MCP (official, remote)

Vendor-hosted
What we probed (2026-11-11, no credentials): an MCP initialize POST to https://mcp.posthog.com/mcp returned HTTP 401 with an OAuth challenge (authorization server https://oauth.posthog.com). We did not sign in or use a key, so no tools were listed or called. PostHog's docs state this endpoint, link its source (github.com/PostHog/posthog, services/mcp) and document a personal API key (Authorization: Bearer) as an alternative to OAuth. Per its FAQ the server allows 480 requests per minute and 4,800 per hour per credential, and its tools can read and write across PostHog products (analytics, feature flags, experiments, error tracking, SQL). Scored from the public repo (GitHub reports the monorepo license as NOASSERTION). Core tools not tested.
