About
AWS Labs' MCP suite: describe EC2/S3/Lambda/RDS resources, tail CloudWatch logs, inspect IAM, and orchestrate common ops. Uses the standard AWS credentials chain (env, SSO, IAM roles) so it respects existing least-privilege policies. A good foundation for cloud-cost and on-call agents.

Frequently Asked Questions
Common questions about AWS Core MCP.
- What is the AWS Core MCP for?
- The AWS Core MCP allows you to query AWS services like EC2, S3, Lambda, and RDS. It also enables tailing CloudWatch logs, inspecting IAM configurations, and performing common operational tasks across AWS accounts. It's designed as a foundation for cloud-cost and on-call agents.
- How does the AWS Core MCP handle authentication?
- It uses the standard AWS credentials chain, which includes environment variables, AWS Single Sign-On (SSO), and IAM roles. This approach ensures it respects existing least-privilege policies configured within your AWS environment.
- What AWS services can I interact with using this MCP?
- You can describe resources for services such as EC2, S3, Lambda, and RDS. It also provides capabilities for monitoring CloudWatch logs and inspecting IAM entities. The MCP is broadly focused on core AWS infrastructure management and monitoring.
- Does using the AWS Core MCP incur additional costs?
- The MCP itself is likely open-source and free, as it's from AWS Labs. However, any operations performed through the MCP on AWS services will incur costs based on your standard AWS usage and billing, as it leverages existing AWS infrastructure.
- What is a prerequisite for using the AWS Core MCP?
- A key prerequisite for this MCP is having a properly configured AWS credentials chain. This can involve setting environment variables, configuring AWS SSO, or having appropriate IAM roles and policies set up to grant access to your AWS resources.
- How can I get started with the AWS Core MCP?
- You can find installation and usage documentation on the AWS Labs GitHub page for the MCP at https://awslabs.github.io/mcp/. The repository at https://github.com/awslabs/mcp provides the source code and further details for deployment.
