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 Vantage account to Claude via Composio Connect, enabling it to analyze last month's cloud spend breakdown, list active budgets and recent alerts, apply cost optimization recommendations to project, 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.

3. Connect your Vantage account

Back in Claude, ask it to connect to Vantage or give it any Vantage-related task.

For example, ask Claude to:

  • "Analyze last month's cloud spend breakdown"
  • "List active budgets and recent alerts"
  • "Apply cost optimization recommendations to project"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Vantage account is ready to use.

What is the Vantage Claude Connector, and what's possible with it?

The Vantage MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Vantage account. It provides structured and secure access so your agent can perform Vantage operations on your behalf.

Troubleshooting

1. Why does Claude not use the Composio connector for Vantage?

The connector can show as connected, but Claude must use it in each Vantage conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Vantage again.

2. Why does Claude show an MCP server error before Vantage connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Vantage.

  • 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 Vantage.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Vantage authorization link not work?

The Composio connector is one server. Your Vantage account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Vantage connection.
  • Composio creates a fresh Vantage authorization link.
  • Open that link in your browser and finish the Vantage sign-in.

4. Why do Vantage actions fail after they worked before?

The Vantage connection can expire or lose permission.

  • Ask Claude to inspect the Vantage connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Vantage account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Vantage.
  • If the action still fails with a permission error, check that the connected account has that permission in Vantage itself.

5. How do I switch to a different Vantage account?

Claude can manage the Vantage connection for you.

  • Ask Claude to disconnect or delete the current Vantage account.
  • Ask Claude to connect Vantage again.
  • Open the new Composio authorization link for Vantage.
  • Sign in with the other Vantage account in the browser.
  • After the account connects, ask Claude to retry the Vantage task.

6. Why is my Vantage connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Vantage connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Vantage 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 Vantage.

FAQ

Frequently asked questions

With a standalone Vantage MCP server, the agents and LLMs can only access a fixed set of Vantage tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Vantage and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Vantage tools.

Yes, absolutely. You can configure which Vantage scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Vantage data and credentials are handled as safely as possible.
