Claude Code Cost Analysis
Use StackSpend cost data in Claude Code via MCP. Query line items, daily rollups, and anomaly alerts in natural language. Ask "What were my cloud costs last week?"
StackSpend provides an MCP (Model Context Protocol) server for Claude Code. Connect with an API key, and Claude can fetch line items, daily rollups, and anomaly alerts. Ask questions like "What were my cloud costs last week?" or "Show anomalies from the past 7 days."
The problem
Cost data is in dashboards and APIs. You have to log in or run curl to get answers. Natural language queries would be faster.
Developers and analysts need quick cost insights without switching contexts. "How much did we spend on OpenAI this month?" should be one question.
Integrating cost data into workflows requires custom scripting. No out-of-the-box way to ask an AI assistant.
The solution
StackSpend MCP server exposes get_line_items, get_daily_rollups, and get_anomalies as MCP tools. Claude Code can call them when you ask cost questions.
Add MCP config with your API key. Restart Claude Code. Ask in natural language—Claude uses the tools and returns formatted answers.
Same API key you use for REST. Scoped to line_items:read, rollups:read, anomalies:read. No additional setup beyond MCP config.
