aws-api-mcp-server: For high-level API commands, is the profile specified by AWS_API_MCP_PROFILE_NAME not being used?

[naoki85]

What happened

• I was managing AWS credentials with a specific profile name.
• I set AWS_API_MCP_PROFILE_NAME and used aws-api-mcp-server.
• As shown in the sample, when I typed "List Buckets in us-west-1" and aws s3api list-buckets was suggested, I got results.
• However, when high-level APIs like aws s3 ls were suggested, I got token authentication errors.

What I confirmed

• When reading the code, it appeared that for custom AWS commands, they are executed via the AWS CLI Driver rather than using local credentials.

mcp/src/aws-api-mcp-server/awslabs/aws_api_mcp_server/server.py

Lines 220 to 236 in c486aaf

	try:
	creds = get_local_credentials()
	if ir.command and ir.command.is_awscli_customization:
	response: AwsCliAliasResponse | AwsApiMcpServerErrorResponse = (
	execute_awscli_customization(cli_command)
	)
	if isinstance(response, AwsApiMcpServerErrorResponse):
	await ctx.error(response.detail)
	return response
	return interpret_command(
	cli_command=cli_command,
	credentials=creds,
	default_region=cast(str, DEFAULT_REGION),
	max_results=max_results,
	)

• Indeed, when I set AWS access keys globally without using a profile, the aws s3 ls command also returned results.

What I'd like to ask

1. Is my usage of aws-api-mcp-server correct?
2. I'd like to understand the reason for this implementation. (I think AWS_API_MCP_PROFILE_NAME should be used for custom commands as well)

Thank you for your consideration.

Hi @naoki85

Thank you for the report. This was actually a bug we just fixed yesterday. Our 0.1.3 release should address this issue. AWS_API_MCP_PROFILE_NAME is now used appropriately for both low level commands and high level commands (what we call CLI customizations).

Do give it a try and let us know if you still encounter the issue.

Hi, @PCManticore

Thank you for addressing this issue!
I tried version 0.1.3 and can confirm the issue is resolved in my environment.
