Feature Request: Add HealthEx connector support to Claude Code

Summary

HealthEx connector is available on claude.ai but not functional in Claude Code. Since HealthEx is an official Anthropic partner for health data integration, it would be valuable to extend this connector to Claude Code users.

Current Situation

• HealthEx MCP server exists at https://api.healthex.io/mcp
• OAuth discovery endpoint works: https://api.healthex.io/.well-known/oauth-authorization-server
• The server requires OAuth 2.0 authentication with PKCE
• Dynamic Client Registration is blocked (returns 403)
• Claude Code cannot authenticate because there's no registered client_id

What Works

• HealthEx connector works perfectly on claude.ai
• Users can connect their health records and query them via Claude
• The MCP server endpoint is responsive

What's Needed

Anthropic needs to register Claude Code as an additional OAuth client with HealthEx. This would allow:

1. Claude Code users to authenticate via /mcp command
2. Access to all HealthEx tools (Get Lab Results, Get Medications, etc.)
3. Consistent health data access across Claude platforms

Use Case

Users with both Fitbit and HealthEx connected can get comprehensive health insights by correlating activity patterns with clinical data.
