Unclear It is unclear whether the interactive view already accepted reconnect all another way before.

What

MCP servers are outside tools and services Claude Code connects to. /mcp reconnect all used to be treated as a request to reconnect a single server named "all" in the terminal interface; only a text-reply path handled "all" before. Now:

  • The argument hint reads [reconnect (<server>|all)|enable|disable [<server>|all]].
  • reconnect all reconnects every MCP server that needs it, except IDE servers, and reports "Reconnected N of M MCP server(s)".
  • If some stay disconnected, it suggests running /mcp. In a background session with no terminal attached, the hint says to attach first.
  • If nothing needs reconnecting, it says "No MCP servers need reconnecting".
  • Each failure is logged per server as "mcp reconnect all: … not reconnected".

Why

Claude Code's own notices already told users to reply "/mcp reconnect all". That suggested command now actually retries every dropped server in one step.

Since it was published

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Added since A small documentation edit on Connect Claude Code to tools via MCP touched a line naming /mcp reconnect all after this was published. To retry every server that failed or needs authentication, run `/mcp reconnect all` at the Claude Code prompt in an interactive terminal session. This requires Claude Code v2.1.284 or later. Earlier versions print `MCP server "all" not fou… mcp see the edit
Confirmed since Anthropic's documentation has since written up /mcp reconnect all, on Connect Claude Code to tools via MCP. To retry every server that failed or needs authentication, run `/mcp reconnect all`. In the interactive terminal this requires Claude Code v2.1.284 or later, and earlier versions print `MCP server "all" not found` there. mcp see the edit
