PostHog MCP for Claude Desktop

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

The PostHog connector

The quickest way to install the PostHog MCP into Claude Desktop is the PostHog connector.

Visit the PostHog connector page in the Claude connector directory.
Click Connect to add the connector to your Claude Desktop.
When prompted, sign in to PostHog to finish authentication.

After that, PostHog MCP tools are available in Claude Desktop wherever that connector is supported.

Adding PostHog to your team doesn't connect your account

If you added PostHog to your team as an admin, it's available across your org but not connected to your account. If this is the case, the connector shows a gear icon and Remove from your team instead of Connect.

Connect individually to use it. Go to Settings > Connectors, click Connect on PostHog, and sign in.

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

If you don't see the connector, or you prefer a one-command install, the PostHog Wizard can install the MCP server directly into Claude Desktop:

Terminal

npx @posthog/wizard mcp add

Manual setup

You can also edit Claude Desktop's configuration file directly. For more on Claude's custom connector options, see Anthropic's remote MCP guide.

Open Claude Desktop and navigate to Settings > Developer
Click Edit Config to open the configuration file
Update claude_desktop_config.json with the following configuration:

JSON
{
  "mcpServers": {
    "posthog": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote@latest",
        "https://mcp.posthog.com/mcp"
      ]
    }
  }
}

Save the configuration file and restart Claude Desktop
The MCP server should show as PostHog in your list of Connectors found in Settings > Connectors

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.
