What
When a connector-type MCP server would duplicate an already-configured server, Claude Code now shows it as "hidden" with actionable guidance on how to switch to the alternative.
Details
- Hidden servers display as
<name> · ○ hidden — same URL as your server '<duplicateOf>' - Depending on where the duplicate is configured, users see specific instructions:
- Plugin servers: "To use this connector instead, disable the plugin server in /plugins"
- Local/user/project config: "To use this connector instead:
claude mcp remove <name>" - Dynamic (via
--mcp-config): "To use this connector instead, drop it from your --mcp-config flag" - Enterprise/managed: "An admin-managed server takes precedence here"
- Tracks
duplicateOfandduplicateOfScopefor each suppressed server
Evidence
Duplicate hint rendering (search for "hidden \u2014 same URL as your server") and scope-based guidance (search for "claude mcp remove", "An admin-managed server takes precedence here")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
