PostHog is a product analytics and developer tooling platform that combines event analytics, feature flags, experiments, session replay, error tracking, logs, and related product data tools. It offers both hosted cloud services and self-hosted deployment options for instrumenting and analyzing applications.
PostHog exposes a region-based REST API for its cloud service and an official hosted MCP server at `https://mcp.posthog.com/mcp`; both use PostHog-issued personal API keys according to the docs gathered here.

In PostHog, open Personal API keys, click + Create a personal API Key, give it a label, choose the minimum scopes you need, and copy the key immediately because PostHog only shows the secret once. PostHog's API docs say personal API keys are the right choice for your own scripts and automations, while apps for other users should use OAuth instead.
Point your MCP client at the server URL and approve access in the browser. The server accepts a Client ID Metadata Document (CIMD), so the client authenticates with its own hosted URL as the client_id — nothing to register.
