Claude Chat Connecter

MCP plugin for Claude that lets you share conversations between chats using a generated code. Paste the code in another chat and Claude knows everything that was said all the context, code, decisions, whatever. Works across accounts too.

Requirements

• Node.js 18+

• Claude Desktop or Claude Code

Related MCP server: claude-switchboard

Install

You don't need to clone anything or run a server manually. Claude starts the MCP process itself using npx.

Claude Desktop

Find your config file:

Add this to it (or merge mcpServers if you already have one):

{
  "mcpServers": {
    "claude-chat-connecter": {
      "command": "npx",
      "args": ["-y", "github:abhubx/ClaudeChatConnecter"]
    }
  }
}

Restart Claude Desktop after saving.

Claude Code

claude mcp add claude-chat-connecter -- npx -y github:abhubx/ClaudeChatConnecter

Usage

Export the current chat:

/excode

Claude gives you a CCS2:... code. Copy it.

Import it in another chat (yours or someone else's):

/incode CCS2:H4sIAAAAAAAAA6tW...

Claude reads everything and picks up where it left off. Works at the start of a chat or in the middle of one.

Example

You've been working on something with Claude for a while and want to hand it off:

you: /excode

Claude spits out a code. You send it to your friend.

Your friend opens a new chat:

them: /incode CCS2:H4sIAAAAAAAAA6tWKkktLlGyUlIq...

claude: loaded 1 conversation, 24 messages.

you were debugging a race condition in a useEffect — stale closure over
userId in an async fetch that wasn't getting cancelled on unmount. you
just added an AbortController. want to keep going from there?

Your friend keeps working, then does /excode. Now the code has both conversations in it.

Troubleshooting

Claude doesn't do anything when I type /excode or /incode

The server isn't connected. In Claude Desktop go to Settings → Developer → MCP Servers and check if claude-chat-connecter shows up. If it's not there, your JSON config has a syntax error — run it through jsonlint.com and check for missing commas or braces.

In Claude Code: claude mcp list

npx fails when Claude tries to start the server

Run node --version and make sure it's 18 or higher. On macOS with Homebrew, Claude Desktop sometimes can't find npx because of PATH issues. Fix it by using the full path:

"command": "/opt/homebrew/bin/npx"

Run which npx to get the right path for your machine.

"Unrecognised code format" error

You didn't copy the full code. They can get long. Make sure it starts with CCS2: and has nothing cut off at the end.

Chain didn't carry over when I exported

The chain survives through a token Claude holds in memory. If it gets lost in a long conversation you can just tell Claude "include the chain token when you export" and it'll sort it out.
