## Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.
This guide walks you through the easiest and most secure way to connect your Vercel AI Gateway account to Claude via Composio Connect, enabling it to list available Vercel AI models and specs, generate marketing copy with Vercel model, fetch usage metrics for your models, and more such actions on your behalf without compromising your account security.
Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

## Troubleshooting

### 1. Why does Claude not use the Composio connector for Vercel AI Gateway?

The connector can show as connected, but Claude must use it in each Vercel AI Gateway conversation.
- Click + at the lower left of the chat, or type /.
- Hover Connectors.
- Turn on Composio.
- Ask Claude to connect to Vercel AI Gateway again.

### 2. Why does Claude show an MCP server error before Vercel AI Gateway connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Vercel AI Gateway.
- Check that the connector URL is https://connect.composio.dev/mcp.
- Connectors run from Anthropic's cloud, so your device network is usually not the problem.
- Add the connector again from Customize > Connectors, then ask Claude to connect Vercel AI Gateway.
- If it fails again, send the error and the ofid_ reference id to support@composio.dev.

### 3. Why does the Vercel AI Gateway authorization link not work?

The Composio connector is one server. Your Vercel AI Gateway account connects separately when Claude asks for it.
- If the browser does not open, or the link expires, ask Claude to retry the Vercel AI Gateway connection.
- Composio creates a fresh Vercel AI Gateway authorization link.
- Open that link in your browser and finish the Vercel AI Gateway sign-in.

### 4. Why do Vercel AI Gateway actions fail after they worked before?

The Vercel AI Gateway connection can expire or lose permission.
- Ask Claude to inspect the Vercel AI Gateway connection.
- If the connection is unhealthy, disconnect it when Claude prompts you.
- Reconnect the Vercel AI Gateway account and retry the action.
- If Claude shows a permission prompt, approve it before Claude changes data in Vercel AI Gateway.
- If the action still fails with a permission error, check that the connected account has that permission in Vercel AI Gateway itself.

### 5. How do I switch to a different Vercel AI Gateway account?

Claude can manage the Vercel AI Gateway connection for you.
- Ask Claude to disconnect or delete the current Vercel AI Gateway account.
- Ask Claude to connect Vercel AI Gateway again.
- Open the new Composio authorization link for Vercel AI Gateway.
- Sign in with the other Vercel AI Gateway account in the browser.
- After the account connects, ask Claude to retry the Vercel AI Gateway task.

### 6. Why is my Vercel AI Gateway connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Vercel AI Gateway connection works in Claude Web, Desktop, and Cowork.
- In Claude Desktop, open Customize > Connectors.
- Next to Composio, click ⋮ and click Clear cache.
- If Vercel AI Gateway tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
- On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Vercel AI Gateway.

## Creating MCP Server - Stand-alone vs Composio SDK

The Vercel AI Gateway MCP server connects Claude Web, Desktop, and Cowork to your Vercel AI Gateway account through Composio. Once connected, Claude can use the available Vercel AI Gateway tools and triggers to complete tasks on your behalf.
