Hosted remote server — no local install to maintain

Installation

Set up this MCP server in your favorite AI agent — copy a ready-made configuration below.

Any MCP-compatible agent

Most agents (Claude, Cursor, Windsurf, VS Code, and more) read a standard mcpServers configuration.

Open your agent's MCP configuration file.
Merge the snippet below into it, filling in the environment variables with your own values.
Restart the agent — the "PostHog" tools will be available.

{
  "mcpServers": {
    "posthog": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.posthog.com/mcp"
      ],
      "env": {
        "POSTHOG_AUTH_HEADER": "Bearer <your-personal-api-key>"
      }
    }
  }
}

Claude Code

Add the server with a single CLI command.

claude mcp add posthog -e POSTHOG_AUTH_HEADER=Bearer <your-personal-api-key> -- npx -y mcp-remote https://mcp.posthog.com/mcp

Claude Desktop

Add the server to claude_desktop_config.json (Settings → Developer → Edit Config).

{
  "mcpServers": {
    "posthog": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.posthog.com/mcp"
      ],
      "env": {
        "POSTHOG_AUTH_HEADER": "Bearer <your-personal-api-key>"
      }
    }
  }
}

Description

The official PostHog MCP server connects an AI agent directly to your PostHog project, turning product analytics into something you can interrogate in plain language. An agent can run HogQL queries against your event data, build and read insights and dashboards, inspect trends and funnels, create and toggle feature flags, launch and analyze experiments, and pull error-tracking stack traces without leaving the editor.

It is a hosted remote server rather than a local process, so there is nothing to run or keep updated: authenticate with a PostHog personal API key and connect from Claude Code, Claude Desktop, Cursor, VS Code, Windsurf, or any other MCP client. The fastest setup is PostHog's own installer, npx @posthog/wizard mcp add, which detects supported clients and writes the config for you across 25+ environments.

Connecting to the server and calling its tools is free. A handful of tools use LLMs internally and are billed as PostHog AI spend; those are only available when AI data processing is enabled in your organization settings.
