Summary
Upgrade
@modelcontextprotocol/sdkfrom 1.15.1 to 1.25.2 to fix OAuth discovery for external authorization servers.Fixes #7228
Problem
When an MCP server's protected resource metadata returns an external
authorization_serversURL (e.g., Auth0), OpenCode incorrectly fetches/.well-known/oauth-authorization-serverfrom the MCP server instead of the authorization server.Solution
Upgrade the MCP SDK to 1.25.2, which fixes the URL construction in
discoverOAuthMetadata().Related
PR #5940 addresses the same SDK bug but also adds a
redirectUriconfiguration option. This PR is a minimal fix focusing only on the SDK upgrade. TheredirectUrifeature could be considered separately.
