# AWS Billing — how to use (mcp.ai)

AWS Cost Explorer cost, forecast, and anomaly reporting through user-connected IAM credentials.

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_aws_billing?ms=1781045340000`
Add it as a custom/remote MCP connector in your client (Claude, Cursor, VS Code…), then authenticate when prompted. Once connected, ask the agent to use the server's tools (e.g. `aws_billing_anomalies`).

## Option B — via direct REST API
Base URL: `https://api.mcp.ai/api/aws_billing`
Auth: `Authorization: Bearer sk_live_…` — create a workspace API key at https://mcp.ai/settings/api-keys
Discover endpoints: `GET https://api.mcp.ai/api/aws_billing/_endpoints`

### Endpoints

  - body: { days_back?: integer, start_date?: string, end_date?: string, limit?: integer, account?: string }
- `POST https://api.mcp.ai/api/aws_billing/cost` — Get normalized AWS Cost Explorer cost and usage with daily breakdown and top services. The adapter drains NextPageToken internally.
