Implement MCP server

[tonyxwz]

This is an MCP server that can execute any AWS CLI command supported by the current user's installed aws cli.

This is more of a feature request than a PR. The implementation is far from prod ready, just a demo to show that what are possible.

Issue #, if available: No issues. Just an idea that I feel worthy of exploring by the aws cli devs. Currently there are too many AWS MCP servers in the awslabs/mcp repository, and to be honest, almost none of them are very useful.

I think the AWS CLI itself should be the place where AWS MCP server is implemented (at least the local version).

After all, the github repository description says:

Universal Command Line Interface for Amazon Web Services

Description of changes:

Just add one command

aws mcp-server start

or

aws mcp-server start --transport streamable-http

Result (testing with npx @modelcontextprotocol/inspector):

You need to install the mcp python SDK to test this PR:

pip install mcp

Check your MCP client such as https://code.visualstudio.com/docs/copilot/chat/mcp-servers to add the server to your coding assistant.

Thanks for kicking off this discussion @tonyxwz! I think it does make sense as a feature request if you want to create one in paralle to thisl, that might be more visible to the community for collecting feedback and 👍 s.

The closest one in awslabs/mcp is probably aws-api-mcp-server, which is built on top of the CLI:

• https://awslabs.github.io/mcp/servers/aws-api-mcp-server/
• https://github.com/awslabs/mcp/tree/main/src/aws-api-mcp-server

Curious if you've tried that one?

@ashovlin Thanks for your response. Should I create a feature request issue instead?

I tried them, but I feel aws cli is a better place to expose arbitrary aws command knowledge to my LLM assistant because I do not want to instead another command line program for aws which relies on a different version of awscli (v1 instead of v2). All the v2 commands do not work with aws api mcp server, yet almost all the new knowledge of LLM is for v2.
