What's Wrong?

## Summary
Authenticating any of the plugin_financial-analysis_* MCP servers fails with a Cognito error indicating the OAuth app client has hit its 100-redirect-URI limit. This affects all sub-providers under the
financial-analysis plugin (factset, sp-global, pitchbook, moodys, morningstar, lseg, daloopa, aiera, chronograph, egnyte). Other MCP servers (Outlook Draft, Databricks, GitHub, Asana, etc.) authenticate
fine.
## Error
{"error":"internal_server_error","message":"Cannot add redirect URI: Cognito callback URL limit (100) reached for client 2cig6ej24hs81ffd6fscgb13gc"}

What Should Happen?

## Reproduction

1. In Claude Code, run /mcp.
2. Select any plugin_financial-analysis_* server (I tried [factset / sp-global / pitchbook — fill in which ones you actually tried]).
3. Click authenticate → browser opens → error renders before the OAuth provider's sign-in page.
