MCP integration missing client_name parameter

[markstur]

Pre-requisities

• I am using the newest version of the platform (agentstack version shows that CLI and platform are the same version, and there is no newer version available)

Describe the bug
Error running "Example: Direct MCP Client with OAuth" here: http://localhost:3333/development/agent-integration/mcp#example:-direct-mcp-client-with-oauth

Missing client_name. Trying to fix the example if it is a docs bug, but do not have any working example yet.

File "/Users/markstur/.cache/uv/archive-v0/HYZTGaBZh9WMs5DIP7SfR/lib/python3.13/site-packages/mcp/client/auth/utils.py", line 234, in handle_registration_response
| raise OAuthRegistrationError(f"Registration failed: {response.status_code} {response.text}")
| mcp.client.auth.exceptions.OAuthRegistrationError: Registration failed: 400 {
| "error": "invalid_client_metadata",
| "error_description": "Missing required param: client_name."

To Reproduce
Steps to reproduce the behavior:

1. Go to 'https://agentstack.beeai.dev/stable/agent-integration/mcp#example-direct-mcp-client-with-oauth'
2. Copy the code to a file
3. Run using uv with agentstack-sdk
4. Say hi in the chat window and get error (details in agent output)

@jenna-winkler issue for MCP example mentioned today

If we can't get a working example I might want to remove this one from the docs for now.

The MCP OAuth example fails because the required client_name parameter is missing from the OAuth client metadata during registration. The current implementation of OAuthExtensionServer in the SDK only sets redirect_uris and does not include client_name, which directly causes the error you’re seeing. There isn’t a working example or merged fix for this as of now. To resolve it, the SDK and the docs example both need to be updated to include client_name when building OAuthClientMetadata during registration. Until that’s addressed, it’s reasonable to remove or warn about this example in the docs to avoid confusion for others.
