Connect Real World MCP to your AI client

Claude (web and desktop)

1. Click Add Real World MCP to Claude ↗. Claude opens Add custom connector with the name and URL filled in. If you are signed out, sign in first.
2. Or add it by hand: go to Customize → Connectors, click + Add, then Add custom connector. Name it Real World MCP and paste the URL below. Click Continue.
3. Under Authentication, pick No sign in. Click Add.
4. In a chat, click +, open Connectors, and turn Real World MCP on.

Free plans can add one custom connector. On Team and Enterprise plans an Owner adds it first under Organization settings → Connectors → Add → Custom → Web (or with the admin install link ↗); members then click Connect under Customize → Connectors. Claude reaches the server from Anthropic's cloud, so it must be public. Ours is.

Custom MCP servers are set up on ChatGPT on the web, and workspace policies apply. OpenAI's help center lists full support on Business, Enterprise and Edu, and read-only use on Pro; check your own Plugins page for your plan. ChatGPT asks you to confirm a tool call unless the tool is marked read-only. Real World MCP has no published ChatGPT app.

Claude Code

1. Run this once in your terminal.
2. Inside Claude Code, type /mcp to check that the server is connected.

claude mcp add --transport http realworldmcp https://www.realworldmcp.com/api/mcp

This uses local scope: only you, in the current project. Add --scope user to use it in every project.

Codex

1. Run this once in your terminal:

codex mcp add realworldmcp --url https://www.realworldmcp.com/api/mcp

Or add this table to ~/.codex/config.toml yourself:

url = "https://www.realworldmcp.com/api/mcp"

The Codex CLI, the Codex IDE extension and the ChatGPT desktop app share this config file.

Gemini (app and CLI)

Gemini app

Google limits custom apps to people 18 or over in the US, signed in with a personal Google Account, with Keep Activity on. You add them on the web; they then work in the mobile app too.

Gemini CLI

Run this once, or add the server to ~/.gemini/settings.json:

gemini mcp add --transport http --scope user realworldmcp https://www.realworldmcp.com/api/mcp

{
  "mcpServers": {
    "realworldmcp": {
      "httpUrl": "https://www.realworldmcp.com/api/mcp"
    }
  }
}

3. Reload MCP servers or restart Cursor.

VS Code and GitHub Copilot

Or, for one workspace, add this to .vscode/mcp.json. You can also run MCP: Add Server from the Command Palette and pick HTTP.

{
  "servers": {
    "realworldmcp": {
      "type": "http",
      "url": "https://www.realworldmcp.com/api/mcp"
    }

2. Add the server below. Remote servers use serverUrl (or url).
3. Save, then press the refresh button in the MCP panel.

{
  "mcpServers": {
    "realworldmcp": {
      "serverUrl": "https://www.realworldmcp.com/api/mcp"
    }
  }
}

Windsurf is now Devin Desktop; its docs moved to docs.devin.ai.

Any other MCP client

Point any client that speaks Streamable HTTP MCP at the URL. The server needs no auth or key.

https://www.realworldmcp.com/api/mcp

{
  "mcpServers": {
    "realworldmcp": {
      "url": "https://www.realworldmcp.com/api/mcp"
    }
  }
}

Scripts can skip MCP: send POST https://www.realworldmcp.com/api/call/<tool_id> with the tool's input as a JSON body.

Not listed

• Meta Muse. The Muse app's connectors come from Meta's reviewed catalog, or Muse builds a custom one from a service's API when you ask. Meta documents no way to paste an MCP server URL into the app, so we don't give steps for it. Source ↗
