PostHog is a product platform for analytics, feature flags, session replay, error tracking, experiments, surveys, data warehousing, and related tooling. It can be used on PostHog Cloud in US/EU regions or on self-hosted instances.
PostHog exposes one HTTP API (private CRUD/query plus public ingestion endpoints), one hosted MCP server, and a public npm-based setup CLI.
- PostHog MCP Serverdetected
- PostHog APIdiscovered
- PostHog Wizard CLIdiscovered
In PostHog, open Personal API keys, click + Create a personal API Key, choose scopes, and copy the key immediately. For MCP-specific manual setup, PostHog also links a preset at user API keys with MCP preset.
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.
Open your project's settings in PostHog at Project settings and copy the project token. PostHog uses this token for public ingestion and feature-flag evaluation endpoints; it is sent in the request payload rather than as a Bearer token.
