Using AWS MCP servers with models hosted outside of AWS Bedrock

[RajvirBains]

Hello team, are there any plans to make these MCP servers available to AWS users who are not using AWS Bedrock? I am thinking how Cline works with any Model and any Model Provider, I should be able use AWS MCP servers the same way and then provide my AWS profile as the target for my actual changes I am implementing. Thanks

Hello! Yes, the architecture of MCP allows you to change the LLM being used in your host+client. Some MCP servers use AWS resources (like Knowledge Base, Nova Canvas) which must have AWS credentials.

Hi @theagenticguy, could you please elaborate on "host+client"? I am using Cline and couldn't figure this out. Thanks

Sure! Cline is an agentic coding assistant that also is an MCP host and client. You can choose any LLM provider that Cline supports for its core agentic coding abilities via Cline settings..

For example, let's say you use Claude Sonnet 3.7 directly from Anthropic's first party service and you want to use Amazon Nova Canvas MCP server for image generation.

In this case, you configure Cline to use your Anthropic API key for the core coding assistant features. And, you must also configure AWS
credentials (separate from Cline settings) in order to use Nova Canvas, since Nova Canvas is only available via Amazon Bedrock and requires an AWS account and IAM credentials.

Thanks @theagenticguy I was getting mislead by the mention of Bedrock in the below text.
