PostHog MCP for Cursor

The PostHog MCP server enables Cursor to directly interact with your PostHog data – managing feature flags, querying analytics, investigating errors, and more.

Cursor plugin

Install the PostHog as a plugin from the Cursor Marketplace or manually in Cursor Settings > Plugins.

Server URL

https://mcp.posthog.com/mcp

The PostHog authentication server automatically routes you to the correct data region (US or EU) based on the account you log in with.

Quick install

The PostHog Wizard can install the MCP server directly into Cursor:

npx @posthog/wizard mcp add

Manual setup

1. Open Cursor and navigate to Cursor Settings > Tools & Integrations

      "url": "https://mcp.posthog.com/mcp"
    }
  }
}

4. Save the configuration file

When you first use the MCP server, you'll be prompted to log in to PostHog to authenticate.

Be mindful of prompt injection – LLMs can be tricked into following untrusted commands, so always review tool calls before executing them.
