About the Vantage MCP Server

The Vantage MCP Server is an open-source tool, written in Golang, that lets you interact with your cloud cost data through AI assistants and MCP clients. By acting as a bridge to Vantage's existing APIs, the Vantage MCP Server lets you query cloud spend data using natural language and makes cost analysis more intuitive.

📝 Note: At this time, the Vantage MCP Server is available only as a locally run service using Standard Input/Output (stdio) Transport, meaning it must be executed on your machine or server and integrated with an MCP client.

Getting Started

Prerequisites

If you're installing from source, ensure the following packages are installed (see .tool-versions for exact versions):

Go
Node.js

You can use a version manager (e.g., asdf) or package manager (e.g., Homebrew) to install these dependencies.

You will also need to create a Read-Only Vantage API token (Write will not work at this time). Follow the instructions on the Vantage API documentation. We recommend creating a brand-new read-only API token for exclusive use with the MCP Server.

Installation

Using Homebrew

brew install vantage-sh/tap/vantage-mcp-server

From Source

Clone this repository.

git clone https://github.com/vantage-sh/vantage-mcp-server

Build the server and adjust permissions.

go build -o vantage-mcp-server
chmod +x vantage-mcp-server

📝 Note: If you pull down new changes from the repository, be sure to re-run go build to rebuild the server and ensure you're running the latest version.

Debug using the MCP inspector.

npx @modelcontextprotocol/inspector -e VANTAGE_BEARER_TOKEN=<token> ./vantage-mcp-server

Set Up MCP Clients

Setup instructions vary depending on which MCP client you use. Example clients include:

See the MCP documentation for a list of available clients. Detailed instructions for Claude for Desktop, Cursor, and Goose are provided below.

Claude for Desktop

Download Claude for Desktop.
From the top of Claude for Desktop, click Claude > Settings (keyboard shortcut Command + ,).
In the left menu of the Settings pane, select Developer.
Click Edit Config. A configuration file is created at:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Open the claude_desktop_config.json file and update its contents. Make sure to replace the placeholders <path_to_compiled_vantage_mcp_server_binary> with the path where you downloaded the Vantage MCP Server binary, and <personal_vantage_api_token> with your Vantage API token.
```
{
  "mcpServers": {
    "Vantage": {
      "command": "<path_to_compiled_vantage_mcp_server_binary>",
      "args": [],
      "env": { "VANTAGE_BEARER_TOKEN": "<personal_vantage_api_token>" }
    }
  }
}
```
Save the configuration file and restart Claude.
In the bottom-right corner of the Claude for Desktop input box, click the hammer icon to see the available tools for the Vantage MCP Server.
Once you've set up the configuration, you can start prompting Claude. Each time you use a new tool, Claude will ask for your approval before proceeding.

Cursor

Download Cursor.
Open Cursor and click Cursor > Settings > Cursor Settings from the menu bar.
In the left pane, select MCP.
Click Add new global MCP Server.
Update the contents of the opened mcp.json file. Make sure to replace the placeholders <path_to_compiled_vantage_mcp_server_binary> with the path where you downloaded the Vantage MCP Server binary, and <personal_vantage_api_token> with your Vantage API token.
```
{
  "mcpServers": {
    "Vantage": {
      "command": "<path_to_compiled_vantage_mcp_server_binary>",
      "args": [],
      "env": { "VANTAGE_BEARER_TOKEN": "<personal_vantage_api_token>" }
    }
  }
}
```

Goose

Download Goose.
Open Goose and click Goose > Settings from the menu bar (keyboard shortcut Command + ,).
Under the Extensions section, click Add custom extension.
In the ID field, enter vantage-mcp-server.
In the Name field, enter Vantage.
In the Description field, enter Query costs and usage data.
In the Command field, enter the path to the Vantage MCP Server binary.
In the Environment Variables section, add a new variable with the name VANTAGE_BEARER_TOKEN and the value set to your Vantage API token.
Click Add.

Note for MacOS users

If you download a release from our Github page and the executable fails to run "because the developer cannot be verified", please open your System Settings. Then find the "Privacy and Security" section. Then scroll to the bottom and you should see a message that "vantage-mcp-server-macos" was blocked, click the "open anyway" button. After this flow, the executable should be able to be run without issue.
