Before you start

  • A PostHog account (PostHog Cloud US or EU)
  • A PostHog personal API key, created under Settings → Personal API keys; the key is passed as a Bearer token in the POSTHOG_AUTH_HEADER
  • An MCP-compatible client (Claude Desktop/Code, Cursor, VS Code, Windsurf, Zed, etc.)
  • Node.js (for the npx wizard installer) when using local stdio setup; the remote server needs no local runtime
  • Optional: AI data processing enabled in PostHog for LLM-powered tools (e.g. natural-language SQL)

PostHog MCP Server (Official Remote) + Claude Desktop FAQ

Where is the Claude Desktop config file?

Claude Desktop reads MCP servers from ~/Library/Application Support/Claude/claude_desktop_config.json. Paste the PostHog MCP Server (Official Remote) config there under the "mcpServers" key and restart the client.

Is PostHog MCP Server (Official Remote) safe to use with Claude Desktop?

The personal API key is sent as a Bearer token and can read analytics, feature flags, and error data; scope it tightly and rotate it if exposed. The connection goes out to PostHog Cloud, so confirm you log in with the correct US/EU region account to keep data in-region.

Is this the official PostHog MCP server?

Yes. It is built and maintained by PostHog. The standalone PostHog/mcp repo was archived in January 2026 and the code now lives in the PostHog monorepo, but it is still the official, supported server.

Do I need to run anything locally?

No. The recommended setup is the hosted remote server at https://mcp.posthog.com/mcp. The npx wizard just writes the config into your client; the remote endpoint handles execution and region routing.

How do I authenticate?

Create a PostHog personal API key and pass it as a Bearer token in the POSTHOG_AUTH_HEADER. The wizard sets this up for you.
