Amazon Bedrock Agent Samples - [ raise ValueError( ValueError: Tool tavily-search has more than 5 parameters. This is not supported by Bedrock Agents.]

Describe the bug
When I try to install tavily-search mcp, it raise exception that " raise ValueError(
ValueError: Tool (tavily-search)[https://github.com/tavily-ai/tavily-mcp/blob/main/README.md] has more than 5 parameters. This is not supported by Bedrock Agents."

Then I found the code, it seems a hard limit, why there is a 5 limits? I tried several mcp servers, there are amount to servers that has more than 5 parameters in its tool.

This is a limit enforced by the API itself and not the SDK.

We are working on getting this limit increased. I will keep this issue open for communication.

I'm having the same issue using Gitlab MCP server
Tool create_or_update_file has more than 5 parameters. This is not supported by Bedrock Agents.

I also encountered the same error.
I am looking forward to this being addressed.

I recommend to just give up using bedrock agents and use langchain
