Documentation over MCP

This documentation has an MCP server of its own. A connected AI client searches it, reads single pages and answers questions about Webmetic with the current content. At the end you have:

• an AI client that answers questions about Webmetic from this documentation, for example "How do I add the tracking code in Google Tag Manager?"
• in Claude Code or Codex, an agent that reads the API reference before it writes code for the Webmetic API

Before you startCopy Anchor Link

• Time: You enter one server address. No sign-in is needed.
• Account: You don't need a Webmetic account, because the documentation is public.
• Access: Your AI client has to support MCP servers over HTTP. ChatGPT, Claude, Claude Code, Cursor, VS Code and Codex do.
• Plan: The server is free and uses no credits.

The server is at this address:

https://webmetic.de/docs/~/mcp

It offers three tools: list_pages lists all pages with their addresses, get_page returns one page as Markdown, and search searches the documentation in German or English. The server reads only this documentation and doesn't access your visitor data. For that, connect the AI assistant.

Clients without MCP read the documentation as text: the index is at https://webmetic.de/docs/llms.txt and the whole documentation at https://webmetic.de/docs/llms-full/en.txt. You can also read every page as Markdown by appending .md to its address.

Claude CodeCopy Anchor Link

1. Run this command in your terminal:

   Copy Text

   claude mcp add --transport http --scope user webmetic-docs https://webmetic.de/docs/~/mcp

   Claude Code is now connected to the documentation. No sign-in is needed.

ClaudeCopy Anchor Link

Claude on claude.ai and Claude Desktop use the same connector, so you set it up only once. The free Claude plan allows exactly one custom connector.

1. In Claude, open Customize > Connectors.

2. Click + Add, then Add custom connector.

3. Enter "Webmetic Docs" as the name and this address as the server URL:

   Copy Text

   https://webmetic.de/docs/~/mcp

4. Click Continue. Claude shows the sign-in settings it detected.

5. Click Continue again.

6. Under Authentication, select No sign in.

7. Click Add. Claude is now connected to the documentation.

In a chat, you turn the connector on or off under + > Connectors.

ChatGPTCopy Anchor Link

1. Open ChatGPT Plugins.

2. Click the plus button, then Add custom MCP server.

3. Enter "Webmetic Docs" as the name.

4. Under Connection, enter this address in the Server URL field:

   Copy Text

   https://webmetic.de/docs/~/mcp

5. For authentication, choose the option without sign-in.

6. Read the risk warning and click I understand and want to continue.

7. Click Create as a plugin.

8. Install the plugin from your personal plugins. ChatGPT is now connected to the documentation.

To have ChatGPT use the documentation, type @ in a chat and select Webmetic Docs.

CursorCopy Anchor Link

1. Open the file ~/.cursor/mcp.json. For a single project, use .cursor/mcp.json in the project folder.

2. Add the server under mcpServers:

   Copy Text

   {
     "mcpServers": {
       "webmetic-docs": {
         "url": "https://webmetic.de/docs/~/mcp"
       }
     }
   }

3. Save the file. Cursor shows the server on the Customize page, and no sign-in is needed.

VS CodeCopy Anchor Link

1. Open the command palette and run MCP: Add Server.

2. Select HTTP (HTTP or Server-Sent Events).

3. Enter this address:

   Copy Text

   https://webmetic.de/docs/~/mcp

4. Enter webmetic-docs as the server ID.

5. Select Global, then Copilot Global, so the server applies in all projects. VS Code is now connected to the documentation.

CodexCopy Anchor Link

1. Run this command in your terminal:

   Copy Text

   codex mcp add webmetic-docs --url https://webmetic.de/docs/~/mcp

   Codex connects to the documentation without signing in.

Check the connectionCopy Anchor Link

Ask your AI client a question about Webmetic, for example "How do I add the tracking code in Google Tag Manager?". The client searches the documentation and answers with the steps from the Google Tag Manager page.

If the connection doesn't workCopy Anchor Link

• The client answers without the documentation: Check that the server is turned on in the client. In Claude you turn it on under + > Connectors, and in ChatGPT you select it with @.
• The client reports that it can't reach the server: The address ends in /docs/~/mcp. Check the tilde and the slashes.
