Vantage MCP Server

What is Vantage MCP Server about?

The Vantage MCP Server acts as a bridge between Vantage's cloud‑cost APIs and AI assistants that support the Model Context Protocol (MCP). By running locally, it enables natural‑language queries such as “How much did we spend on AWS EC2 last month?” and returns structured cost information.

How to use Vantage MCP Server?

1. Prerequisites – install Go (matching versions in .tool-versions) and Node.js.
2. Build – clone the repo, run go build -o vantage-mcp-server, and make the binary executable.
3. Run – start the server via standard I/O transport, e.g., ./vantage-mcp-server.
4. Configure an MCP client (Claude, Cursor, Goose, etc.) by pointing it to the binary and providing the environment variable VANTAGE_BEARER_TOKEN with a read‑only Vantage API token.
5. Interact – invoke tools like query-costs, list-budgets, or list-anomalies from the AI assistant's UI.

Key features of Vantage MCP Server

• Rich toolset exposing 20+ commands (e.g., query-costs, list-cost-reports, list-budgets, list-anomalies).
• VQL support for flexible cost queries.
• Provider‑agnostic – works with AWS, Azure, GCP integrations.
• Self‑hosted binary runs via stdio, ensuring data never leaves your environment.
• Feedback loop – submit-user-feedback lets users send usage insights back to Vantage.

Use cases of Vantage MCP Server

• Finance & budgeting – ask an assistant for current spend vs. budget and get actionable recommendations.
• Cost anomaly detection – quickly surface unexpected spikes with list-anomalies.
• Multi‑cloud reporting – retrieve unified cost data across AWS, Azure, and GCP without writing custom scripts.
• Tag‑driven analysis – filter reports by tags or tag values to attribute spend to teams or projects.
• Forecasting – obtain spending forecasts via get-cost-report-forecast for capacity planning.

FAQ from the Vantage MCP Server

• Do I need a write‑enabled token? No, a read‑only Vantage API token is sufficient.
• Can I run the server remotely? The repo provides the self‑hosted version; a remote variant is documented in Vantage MCP docs.
• What platforms are supported? macOS, Linux, and Windows binaries are available; macOS users may need to allow the executable in Security & Privacy settings.
• How do I update the server? Pull the latest changes and re‑run go build to rebuild the binary.
• Is there a Homebrew package? Yes, install with brew install vantage-sh/tap/vantage-mcp-server.

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: The Vantage MCP Server is available in both self-hosted and remote forms. This repository supports the self-hosted version, which runs locally using Standard Input/Output (stdio) Transport. For a remote alternative, see the Vantage MCP documentation.

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

1. Clone this repository.

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

2. 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.

3. 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:

• Claude for Desktop
• Cursor
• Goose

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

1. Download Claude for Desktop.
2. From the top of Claude for Desktop, click Claude > Settings (keyboard shortcut Command + ,).

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

5. 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": {

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.
