Vantage MCP

• Self-Hosted MCP: With the Self-Hosted MCP, customers are responsible for deploying and managing their own instance of the MCP server, which includes managing API keys, handling authentication, and performing regular updates to keep up with new releases.
• Remote MCP: With the Remote Vantage MCP, Vantage manages all the above items. Customers do not need to deploy a new instance of the MCP when updates are released.

Configure the Self-Hosted Vantage MCP

​

Configure the Remote Vantage MCP

token = os.getenv("VANTAGE_API_TOKEN")

config = {
    "service": {
        "url": "https://mcp.vantage.sh/sse", 
        "transport": "sse", 
        "headers": {
            "Authorization": f"Bearer {token}"
        }
    }
}

​

Step 1 - Download and Install an MCP Client

​

Step 2 - Configure the Vantage MCP Server

{
    "mcpServers": {
        "Vantage MCP Server": {
            "command": "npx",
        "args": ["-y", "mcp-remote", "https://mcp.vantage.sh/sse"],
        "env": {}
        }
    }
}

​

Step 3 - Authorize the Vantage MCP Server

1

Read the authorization information, then click Allow Access to proceed.

2

You will then be prompted to log in to Vantage with your username and password or authenticate via SSO. After you log in to Vantage, you will have access to the Vantage MCP server.

​

Step 4 - Prompt the Vantage MCP Server

• Claude
• Goose

Start a new chat to begin prompting Claude. For example, you can ask, “In Vantage, which workspaces do I have access to?” Claude uses the appropriate MCP tool and replies with workspace access details.

Each time Claude uses a new tool, you’ll be asked to approve it. Click Allow Always to grant ongoing access, or Allow Once to approve it just this time.

You may encounter conversation limits when prompting Claude. If you encounter a limit, create a new chat. As a best practice, keep separate topics in separate chats for better organization.

Examples - Prompt the Vantage MCP

How much did we spend on S3 in us-east-1 over the last 30 days?

I’ll help you find your S3 spending in us-east-1 over the last 30 days. First, let me check your workspace information and available cost providers.

• User identity
• Accessible workspaces
• Cost provider connections (e.g., AWS)

I can see you have access to multiple workspaces. To get your S3 spending data, I’ll need to know which workspace you’d like me to query. I’ll start with the first workspace (‘Marketing Workspace’) and check for AWS S3 costs.

{
  `filter`: `(costs.provider = 'aws' AND costs.service = 'Amazon Simple Storage Service' AND costs.region = 'us-east-1')`,
  `date_bin`: `day`,
  `end_date`: `2025-07-22`,
  `start_date`: `2025-06-22`,
  `workspace_token`: `wrkspc_1234567`
}

It looks like there are no S3 costs in us-east-1 for Marketing Workspace. Let me try a few other workspaces to see if your S3 costs might be in a different workspace. Let me check the “Management” workspace which seems like it might be a primary workspace.

Based on your query for S3 costs in us-east-1 over the last 30 days (June 22 - July 22, 2025), here’s what I found: S3 Spending Summary (us-east-1, Last 30 Days) Total S3 Spend: $55,089.92 The costs are distributed across multiple AWS accounts: Top Spending Accounts: - Account 123456789: ~$25,850+ (dominant portion of spend) …

Prompting Best Practices

• Add context to your prompts. Mention primitives like provider, time frame, workspace, specific service, or tags, when applicable.
  • Example: What was our GCP BigQuery spend for September and October 2024?
• Construct your prompts using group-by statements to help reduce token consumption (e.g., group costs by month as opposed to day).
• Ask one thing at a time and avoid stacking various unrelated questions. Instead of, “What were our EC2 costs last month, and also which accounts are over budget, and can you tell me if any tags are missing?” consider asking these as separate prompts to keep responses organized and information relevant.
• Be specific. Don’t assume the client knows what terms like “important” mean. Instead of “What are my most important costs to monitor?”, try something more specific, like, “Which services have the highest costs without tags?” or “Which accounts had the biggest increase in spend over the past two months?”
• Be clear about the format of the output you want. If you’d like results in a table, chart, or summary, specify that in your prompt.
  • Example: Show me EC2 spend in us-east-1 last month by instance type in a table, with instance types in the first column and costs in the second.

​

Validating Responses

• Use your existing Cost Reports or as a source of truth. For example, if you ask about EC2 spend last month, you can validate the answer against your saved report for that timeframe.
• When you prompt a client, like Goose or Claude, you can expand the tool calls (such as query-costs) to view the underlying request details. You can then use this logic to help confirm whether the filters and groupings align with your intent.
• If you find a response that appears inaccurate or misleading, share the full prompt and result with our team. See the Feedback section below for details.
