TL;DR

Server: PostHog MCP server
Vendor: PostHog
Category: Indie SaaS infrastructure
Distribution: npm package (runs locally)
TL;DR: PostHog's official MCP server exposes product analytics, insights, and feature flag state as MCP tools. The agent can ask questions like 'how many users hit the diagnostic page yesterday' or 'which flag is gating onboarding' and get a structured answer grounded in your PostHog project, not a guess.
Founder fit: If you are already using PostHog for product analytics, this server turns Claude into a competent product-analyst pair. Drop in a question about activation, retention, or a specific event and let the assistant write the insight against your real project rather than hallucinating numbers.

Why an indie SaaS founder cares

Install

Access: Requires a PostHog personal API key with appropriate scopes.

Claude Desktop

Add the following block to your claude_desktop_config.json and restart Claude:

{
  "mcpServers": {
    "posthog": {
      "command": "npx",
      "args": ["-y", "@posthog/mcp-server"]
    }
  }
}

Cursor

Add the following block to .cursor/mcp.json in your home directory or project root:

{
  "mcpServers": {
    "posthog": {
      "command": "npx",
      "args": ["-y", "@posthog/mcp-server"]
    }
  }
}

Install snippets are derived from the vendor's published distribution shape. If your client is neither Claude Desktop nor Cursor, see the vendor docs for client-specific configuration.
