1. Why Do You NEED This Feature?

Many MCP Servers are moving to this OAuth model, which makes it much more user-friendly to connect services.
Claude Code has this out of the box, so having this in place will make it easier for users to migrate.

2. What Is NOT Possible Right Now?

Any MCP which is only available through OAuth is inaccessible.

3. What WILL Be Possible With This Feature?

Trivially connecting Atlassian MCP for Jira/Confluence

Proposed Solution (User Experience)

User should add an MCP using existing methods

• Forge Code should detect this requires OAuth through one of the two discovery mechanisms described in the spec.
• Forge code should prompt the user to go through an OAuth flow to authenticate to the MCP server

MCP Integration

Priority/Impact

Critical - Blocking my work

Examples from Other Tools

Cursor, Claude Code, Codex CLI all support OAuth for MCP servers, and have for some time.

Additional Context

Marking this as critical, as I believe there are some MCP servers which are only viable through OAuth because they issue short-lived tokens which must be refreshed using refresh tokens.
