Get session id sample code #564

[scholtz]

Sample code how to access the session id.

Motivation and Context

Showcase #564

When this issue will be solved I believe this may be useful information for everybody how to obtain session id in the tool.

How Has This Been Tested?

Through local mcp tool in vscode.

{
"servers": {
"Local1": {
"command": "npx",
"cwd": "${input:cwd}",
"args": ["mcp-remote", "http://localhost:5002/mcp/", "--transport", "http-first"]
}
},
"inputs": [
{
"id": "cwd",
"type": "promptString",
"description": "Working Directory"
},
{
"id": "debugType",
"type": "promptString",
"description": "Debug Type"
}
]
}

is there anything i can help so that this sample code can be merged into the samples?

[eiriktsarpalis]

This sample seems somewhat artificial to me -- the session id is mostly intended as a key for session state so it would be nice to have an example showcasing that.

Hi @scholtz. Thanks for your contribution. I agree with @eiriktsarpalis that a little contrived and not substantial enough to warrant an entire sample. If there were some useful way to use the session id to key into session state in the new AspNetCoreMcpPerSessionTools added by #724, that might be interesting. I could see the AspNetCoreMcpPerSessionTools being the sample we end up using to demo more advanced features like querying the session ID.
