Problem Statement

Summary

Hi team! 👋 First off, thank you for the amazing work on Claude Code - it's been incredibly helpful for my development workflow!

I'd love to see custom MCP connectors supported in remote sessions (Claude Code on the web). Currently, custom connectors configured in Claude.ai settings work great in the chat interface, but they're not available when using Claude Code Web.

Use Case

I've set up a custom MCP server for Cloudflare R2 blob storage to manage game assets for my project. The workflow I'm hoping for:

• Claude Code Web reads/writes asset configurations directly to R2
• No need to switch between Claude.ai chat and Claude Code Web
• Seamless data management while coding

Current Behavior

• ✅ Custom MCP works in Claude.ai chat
• ✅ Custom MCP works in Claude Code CLI (with claude mcp add)
• ✅ Built-in connectors (GitHub, Google Drive) work in Claude Code Web
• ❌ Custom MCP connectors are not available in Claude Code Web remote sessions

Proposed Solution

Proposed Solution

Allow custom MCP connectors configured in Claude.ai settings (or via .mcp.json) to be available in Claude Code Web remote sessions as well.

Why This Matters

Many developers are building custom MCP servers for their specific infrastructure (databases, storage, internal APIs). Being able to use these in Claude Code Web would make the remote coding experience much more powerful and flexible.

I totally understand there may be security or infrastructure considerations here - just wanted to share this as a feature that would be really valuable for the community. No rush, and thanks again for all your hard work! 🙏
