Claude Code v2.1.238 20 Aug 2026

Suppressed plugin MCP servers are recorded in state

Under the hood

Useful1 Signal2

MCP

Plugin MCP servers skipped for duplicating a claude.ai connector are now tracked in MCP state.

What

When a plugin's MCP server duplicates a claude.ai connector and is skipped, its name is now stored in MCP state under suppressedPluginMcpServers, replacing the older per-connector tracking here.

Details

Pending connections, not just established ones, are now torn down through a detached dispose.

Evidence

suppressedPluginMcpServers

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
