Overview
The Vantage MCP Server is an open-source tool written in Go that lets you interact with cloud cost data through AI assistants and MCP clients. It acts as a bridge to Vantage's existing APIs, enabling natural-language querying of cloud spend and making cost analysis more intuitive. The server supports both self-hosted and remote deployments; this repository provides the self-hosted variant that runs locally via Standard Input/Output (stdio) transport, with a remote option described in the Vantage MCP documentation. Prerequisites include Go and Node.js, and a read-only Vantage API token is required for access. Installation can be done via Homebrew or from source, and users can debug with the MCP inspector. The server exposes a suite of MCP tools that clients can invoke (e.g., Claude, Cursor, Goose) to query and explore cost data, reports, forecasts, and configurations. Available tools include querying costs with VQL, listing costs and cost reports, obtaining cost-forecasts, and discovering provider integrations, providers, budgets, dashboards, tags, and more. It is designed for natural-language-driven cost analysis across an organization’s cloud spend using Vantage APIs.
