Feature Request: Add Beautiful.ai to Connectors Directory

### Problem Statement

Beautiful.ai has a fully functional, production-ready MCP server with
OAuth authentication and 10 tools (create, search, export, themes,
folders, templates). However, it is only usable via manual MCP server
configuration in Claude Desktop.

Users on claude.ai (browser and mobile) cannot access Beautiful.ai
because it is not listed in the Connectors Directory. This means
presentation creation — one of the most common professional workflows
— requires switching to Claude Desktop or leaving Claude entirely.

The MCP server already exists and works:
- MCP URL: https://openai-mcp-696419881849.us-central1.run.app/mcp
- OAuth: https://www.beautiful.ai/provisioning/oauth2
- Docs: https://support.beautiful.ai/hc/en-us/articles/44246954338829

### Proposed Solution

Add Beautiful.ai to the Connectors Directory so it is discoverable and
connectable from claude.ai browser, mobile, and desktop without manual
configuration.

Since Beautiful.ai already has a production MCP server with full OAuth
2.0 support, the technical requirements for directory listing appear to
be met. The submission process at
claude.com/docs/connectors/building/submission would need to be
initiated — either by Beautiful.ai directly or through Anthropic
outreach to encourage their submission.

Currently the directory includes presentation tools like Gamma and
SlidesGPT, but Beautiful.ai offers a more complete toolset (structured
outline creation, template management, theme selection, PDF/PPTX
export) that would meaningfully expand Claude's presentation
capabilities for browser users.

### Alternatives Considered

1. Manual MCP server addition in Claude Desktop — works, but limits
usage to desktop only. Not available on claude.ai browser or mobile
where most users interact with Claude.

2. Direct API calls from a browser artifact — tested and failed.
Beautiful.ai's API enforces CORS restrictions, blocking cross-origin
requests from claude.ai artifacts. This is not a viable workaround.

3. Using other listed connectors (Gamma, SlidesGPT) — these are
available in the directory but offer fewer capabilities than
Beautiful.ai's MCP implementation, which includes template variable
inspection, folder management, theme selection, and outline review
before generation.

4. Exporting PPTX from Claude and importing into Beautiful.ai — adds
unnecessary friction and loses Beautiful.ai's native AI formatting,
theme system, and collaboration features.
