Upgrade mcp-sdk version and support SSE mode

• Compatible with both the new StreamableHTTPClientTransport and legacy SSEClientTransport communication protocols
• Fixed an issue in stdio mode where the PATH variable was lost when passing a custom env parameter (see: Default Environment should be appended with custom env's passed to client (instead of replacing) modelcontextprotocol/typescript-sdk#216 (comment))

Stdio:

SSE:

HI，You can use the following Baidu search MCP tool for testing. Its capability is internet search. The api_key provided here is temporary and will be deactivated after you complete your testing:
{ "url": "http://appbuilder.baidu.com/v2/ai_search/mcp/sse?api_key=Bearer+bce-v3/ALTAK-pzdF6JO6W40X1nE6uHk1x/eddae689457cedaa6dc54c2af2f10e8b2e13defa" }

@zerogu it works pretty well. Feel free to redact the API key; I have passed it to @HenryHengZJ in case he wants to test it too.

this is awesome, tested and works!

Thank you so much for sharing these insights @zerogu. Is the API still working? If NO, can you either help me with a working one or help creating a new one?

Hi, I’ve regenerated a new one for you.
You can use the following for testing:

{
  "url": "http://appbuilder.baidu.com/v2/ai_search/mcp/sse?api_key=Bearer+bce-v3/ALTAK-2uD1hC2JXLLtnKlm5xCRR/9b80a24bdfe37b323aff858e2c7e16667147f501"
}

Please let me know once you’re done — I’ll delete it afterwards.

@zerogu Thanks for the API, I do not see any available actions as you guys. You think my chatflow is wrong, I have replicated exactly how you have it up there. I see an error and looks like the api is not loading. I am using AWS bedrock wrapper fyi.

Is it configured like this?

[NikMuth14]

Hey, I have attached my Git hub repo link below, Can you please check if I had configured it the right way. Also, yes I had tried configuring Flowise the way you show it here, it did not work for me.
