--- title: Connect an AI app description: Add the Qaf MCP server to Claude, ChatGPT, Claude Code, Codex, Cursor, VS Code or another MCP app, then sign in with your Qaf account. --- Every app connects to the same server URL. After you add it, the app opens a Qaf sign-in page in your browser: sign in with your Qaf account and allow access. ```text https://api.qaf.ai/mcp ``` App menus change often. If a step doesn't match what you see, follow the app's own guide, linked in each tab. **Claude** 1. In Claude, open **Customize › Connectors** and select **Add › Add custom connector**. 2. Name it Qaf, paste the server URL and select **Continue**. Review the detected settings and select **Continue** again. 3. Under **Authentication**, keep **Sign in now**. Under **OAuth client**, choose **Register automatically**: Qaf doesn't support Claude's published identity. 4. Select **Add**, then sign in with your Qaf account and allow access. On Team and Enterprise plans, an owner adds the connector first, under **Organization settings › Connectors**. Each member then selects **Connect** next to it in **Customize › Connectors**. To use Qaf in a chat, select **+** in the message box, open **Connectors** and turn on Qaf. Claude's guide: [Get started with custom connectors using remote MCP](https://support.claude.com/en/articles/11175166-get-started-with-custom-connectors-using-remote-mcp). **ChatGPT** 1. In ChatGPT on the web, open [Plugins](https://chatgpt.com/plugins), select **+** and choose **Add custom MCP server**. 2. Name it Qaf and paste the server URL under **Connection**. For authentication, choose **OAuth**. 3. Read the warning, select **I understand and want to continue**, then **Create as a plugin**. 4. Install the plugin, then sign in with your Qaf account and allow access. To use Qaf in a conversation, type **@** in the message box and select Qaf. In a workspace, admin settings can restrict custom MCP servers. OpenAI's guide: [Add custom MCP server](https://developers.openai.com/api/docs/guides/custom-mcp-server). **Claude Code** 1. Add the server for all your projects: ```bash claude mcp add --transport http --scope user qaf https://api.qaf.ai/mcp ``` 2. In Claude Code, run `/mcp`, select qaf and sign in with your Qaf account in the browser that opens. To sign in from a terminal without a session, run `claude mcp login qaf`. Anthropic's guide: [Connect Claude Code to tools via MCP](https://code.claude.com/docs/en/mcp). **Codex** 1. Add the server: ```bash codex mcp add qaf --url https://api.qaf.ai/mcp ``` 2. Sign in with your Qaf account in the browser that opens: ```bash codex mcp login qaf ``` The Codex CLI, the IDE extension and the ChatGPT desktop app share this setting. It lives in `~/.codex/config.toml`: ```toml [mcp_servers.qaf] url = "https://api.qaf.ai/mcp" ``` OpenAI's guide: [MCP in Codex](https://learn.chatgpt.com/docs/extend/mcp?surface=cli). **Cursor** 1. [Add Qaf to Cursor](cursor://anysphere.cursor-deeplink/mcp/install?name=qaf&config=eyJ1cmwiOiJodHRwczovL2FwaS5xYWYuYWkvbWNwIn0=), or add it to `~/.cursor/mcp.json` yourself. If the file exists, add the `qaf` entry to its `mcpServers`. ```json { "mcpServers": { "qaf": { "url": "https://api.qaf.ai/mcp" } } } ``` 2. Open **Customize** in Cursor, turn on qaf, and sign in with your Qaf account when the browser opens. Cursor's guide: [Model Context Protocol](https://cursor.com/docs/mcp). **VS Code** 1. In VS Code, run **MCP: Add Server** from the Command Palette. 2. Choose **HTTP (HTTP or Server-Sent Events)**, paste the server URL and enter `qaf` as the server ID. 3. Select **Global**, then **Copilot Global**, to use it in every workspace. 4. When VS Code starts the server, sign in with your Qaf account in the browser that opens. To share it with everyone who works on a project, add it to `.mcp.json` at the workspace root: ```json { "mcpServers": { "qaf": { "type": "http", "url": "https://api.qaf.ai/mcp" } } } ``` **MCP: Add Server** offers this file only when the experimental `chat.mcp.workspaceRootConfig.enabled` setting is on. An existing `.mcp.json` works with the setting off. VS Code's guide: [Add and use MCP servers in VS Code](https://code.visualstudio.com/docs/agent-customization/mcp-servers). **Other apps** Any app that supports remote MCP servers with OAuth sign-in can connect. It needs: - **Server URL:** `https://api.qaf.ai/mcp` - **Transport:** Streamable HTTP - **Sign-in:** OAuth 2.1 with dynamic client registration and PKCE. The app registers itself; there's no client ID to enter. An app that only runs local (stdio) servers can reach Qaf through the [mcp-remote](https://github.com/punkpeye/mcp-remote) bridge: ```json { "mcpServers": { "qaf": { "command": "npx", "args": ["mcp-remote", "https://api.qaf.ai/mcp"] } } } ``` Building a client? [Sign-in and connected apps](/mcp/authentication#for-client-developers) lists the endpoints and protocol details. ## Troubleshooting **The app can't connect** Check that the URL is exactly `https://api.qaf.ai/mcp`. The app must support remote MCP servers over Streamable HTTP; an app that only runs local servers needs the bridge in **Other apps**. **Your account can't connect** The sign-in page says so when an account can't use the server. A guest session can't connect: sign in to qaf.ai with an account first. An account that is waiting to be deleted, or is suspended, can't connect either. If you think your account should have access, email us at contact@qaf.ai. **The sign-in page doesn't open** Allow pop-ups for the app's site, then try again. On a machine without a browser, run `claude mcp login qaf --no-browser` or `codex mcp login qaf --no-browser` and follow the prompt. **Qaf's tools don't appear** Most apps need the server turned on for each chat or workspace: in Claude, turn on Qaf under **+ › Connectors**; in ChatGPT, type **@** and select Qaf; in Cursor, turn on qaf in **Customize**. If the tools still don't appear, remove the server and add it again. **The app asks you to sign in again** An app stays signed in while you use it. It has to sign in again after 30 days without use, or after you disconnect it. In Claude Code, run `/mcp`, select qaf and choose **Re-authenticate**. In Codex, run `codex mcp login qaf`. In other apps, remove the server and add it again.
