MCP Configuration
MCP server requiring OAuth login
Some MCP servers authenticate via a browser-based OAuth flow rather than a static API key, similar to how Claude Code's own login works.
For servers that wrap a service with proper user accounts, OAuth is the more common pattern than a hardcoded key — you complete a login in the browser once, and the server holds onto the resulting token.
If that flow doesn't complete, it's usually a browser or redirect issue rather than anything about Claude Code's own configuration — worth trying the same login flow directly against the service outside of Claude Code to isolate where it's actually failing.
A token that later expires will surface as the server suddenly failing after previously working fine, which is a reasonable first thing to suspect before re-checking the whole config from scratch.
