[Bug] /mcp dialog not scrollable with many configured MCP servers

Bug Description
The /mcp dialog is unusable when many MCP servers are configured.

Specifically:

• Claude Code renders every advertised connector from the claude.ai

catalog (~30 entries on my account, all "Needs authentication")
alongside my locally-configured servers. These catalog entries
cannot be disconnected from claude.ai web settings because they
were never connected — they're just advertised.

• Combined with my local servers, the /mcp list has ~50 entries.
• The dialog fills the entire terminal viewport and does not scroll

with arrow keys, PgDn, or ctrl+d. I can't reach the MCPs at the
bottom of the list, which is where my actually-used servers (paper,
kosh-query, braintrust, etc.) sit.

• claude mcp get "claude.ai <name>" reports "not found" while

claude mcp list shows the entry — confirming these are runtime-
injected from the catalog, not in any local config file.

Requested fixes (any one would help):

1. A setting to suppress unauthenticated claude.ai catalog entries

from /mcp (e.g. showClaudeAiCatalog: false in settings.json).

1. Scroll / pagination support in the /mcp dialog when entries

exceed viewport height.

1. Scope filter in /mcp (user / project / catalog tabs or toggles).

Repro: have an active claude.ai account with the default connector
catalog, plus ~15+ locally-configured MCPs, then run /mcp.
