Bionic MCP registration doesn't send grant_types or response_types

[coolaj86]

Technically this isn't a bug.

But the landscape is wide, most MCP implementations are for Claude, and this behaves differently from Claude in an unimportant but RFC-compliant way.

However, if it behaved more like Claude in its RFC-compliant way, it would be compatible with more tools.

Which version of LM Studio Bionic?
Example: LM Studio 1.1.1+5

Which operating system?
macOS

What is the bug?
MCP registration doesn't specify { "grant_types": ["authorization_code"], "response_types": ["code"] }, but it could which would be more clear and more compatible - because that's what Claude does.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Settings'
2. Click on 'Connected Apps'
3. Scroll down to 'Manual MCP server setup'
4. + Add Custom MCP
5. Connect to an MCP that's only been tested against Claude's MCP and follows that rather than a perfect RFC implementation, see error about grant_types.
