AWS Cost and Usage Report Service MCP Server Integration Guide
Section A: Quick Answer & Architectural Summary
The AWS Cost and Usage Report Service Model Context Protocol (MCP) integration bridges AI coding assistants to the AWS Cost and Usage Report Service cloud infrastructure API. It exposes 4 validated endpoint operations as callable tools for Claude Desktop, Cursor, and VS Code. Configuration is managed via hosted registry at /config/amazonaws-com-cur.json or local stdio bridge execution. Operates with zero authentication credentials out of the box. Contains 4 mutating operations (POST/PUT/DELETE); user confirmation is recommended before triggering write operations.

Technical Overview & Protocol Integration
The AWS Cost and Usage Report API, provided by Amazon Web Services, is a powerful programmatic interface for managing the lifecycle of your Cost and Usage Reports. It moves beyond basic billing visibility to offer a granular, machine-readable record of your cloud expenditure and usage patterns. Through this API, developers can create, modify, describe, and delete report definitions—the blueprints that dictate what data is collected, how it's aggregated, and where the resulting reports are stored in Amazon S3. Its core capabilities empower automation and integration, enabling enterprises to build sophisticated financial operations (FinOps) and cloud cost management pipelines. Typical use cases include automating the creation of detailed cost allocation reports for departmental chargeback, programmatically adjusting report delivery schedules or content to align with new fiscal periods, and managing the entire report lifecycle as part of Infrastructure as Code (IaC) deployments, ensuring consistent cost governance across multiple AWS accounts.
When exposed as a tool via the Model Context Protocol (MCP) to an AI coding assistant, this API's value is significantly amplified, transforming static reporting into a dynamic, conversational cost intelligence layer. An AI agent, such as Claude Desktop or Cursor, can leverage this MCP server to act as a FinOps co-pilot. Instead of manually navigating the AWS Management Console or writing one-off scripts, a developer can instruct the AI in natural language to perform complex report management tasks. This creates a powerful bridge between human intent and cloud cost infrastructure, allowing for rapid iteration on cost reporting strategies. The AI can understand context, chain operations together, and handle the syntax of API calls, drastically reducing the cognitive overhead and time required to maintain and adapt cost tracking systems in fast-paced DevOps and engineering environments.
Practical workflow examples highlight this dynamic capability. A developer could instruct the AI: "Query all current report definitions to identify any tracking costs for our production account but not our staging environment, and then describe their current configurations." The AI would use the DescribeReportDefinitions endpoint to fetch the data, analyze it against the natural language criteria, and present a summary. Further, one could command: "Create a new daily report definition for our data analytics project, include resource-level tags 'Project' and 'Team', and set the S3 destination to our central billing bucket." The AI agent would then orchestrate a sequence of calls, likely using PutReportDefinition, to execute this multi-step creation and configuration task. Another powerful automation is: "Find and delete any report definitions that haven't been modified in over six months," where the AI would use DescribeReportDefinitions to list reports, analyze modification timestamps, and then systematically call DeleteReportDefinition for stale entries, performing critical hygiene and cost optimization on the reporting infrastructure itself.
While the API endpoint structure suggests an authentication model delegated to an underlying gateway (as indicated by the "None" specification for this layer), developers must strictly adhere to AWS security best practices. Access to this API must be governed through AWS Identity and Access Management (IAM) with meticulously crafted policies following the principle of least privilege. An IAM entity (user, role) used for this integration should only have the exact permissions required (e.g., "cur:PutReportDefinition", "cur:DescribeReportDefinitions") and be constrained to specific, known report names or S3 bucket resources where possible. Credentials should be managed via secure methods like environment variables or AWS Secrets Manager, never hardcoded. When configuring the MCP server, developers should ensure that the AWS access keys or assumed role credentials used have the minimal necessary permissions and that network controls (like VPC endpoints for AWS services) are considered to secure data in transit. This foundational security posture ensures that the powerful automation granted to the AI agent does not become a liability for unauthorized or misconfigured reporting changes.
By translating the OpenAPI 3.0 specification for AWS Cost and Usage Report Service into native Model Context Protocol (MCP) tool definitions, developers and AI agents gain programmatic access to endpoints over stdio or HTTP transports. Every endpoint is translated into a discrete tool payload complete with input argument validation, parameter descriptions, and return type definitions.

Read & Mutating Operations
Local MCP bridge process making outbound HTTPS requests to upstream API
Isolation & Principle of Least Privilege
Ensure outbound network access to the API endpoint is permitted. Use restricted API tokens with minimal read/write scopes.
Actionable Operational Guidelines
- Verify network firewall rules allow outbound traffic to upstream API endpoints.
- Review arguments for mutating endpoints (/#X-Amz-Target=AWSOrigamiServiceGatewayService.DeleteReportDefinition, /#X-Amz-Target=AWSOrigamiServiceGatewayService.DescribeReportDefinitions, /#X-Amz-Target=AWSOrigamiServiceGatewayService.ModifyReportDefinition) before execution.
- Apply token rate limits and monitor usage in your provider dashboard to prevent unexpected quota consumption.
