Registering a token without leaving it in your shell history

Way 1: run it, then delete one line from your history (quickest)

1. 1Run the command from the Connect screen as usual.
2. 2With zsh on Mac or Linux (the macOS default), open ~/.zsh_history in an editor, delete the claude mcp add line, save, and reopen the terminal.
3. 3With bash on Mac or Linux, run history -d -1 right after (bash 5.0 or later).
4. 4With PowerShell on Windows, run (Get-PSReadLineOption).HistorySavePath to find the history file, open it in an editor, delete the claude mcp add line, save, and reopen PowerShell.

Way 2: pass it in an environment variable (the token is in neither the command nor the repository)

1. 1Copy the token with "Copy just the token" on the Connect screen.
2. 2Put the token in an environment variable, with a different name for each board (see the examples). On Mac or Linux, open your shell's settings file (~/.zshrc, for example) in an editor, add a line, save, and reopen the terminal. On Windows, add it under User variables in Settings → System → About → Advanced system settings → Environment Variables, then reopen the terminal.
3. 3Put that variable's name in the .mcp.json of the repository you want to connect. It contains no token, so it is fine to commit.
4. 4Start Claude Code in that repository, and allow the .mcp.json connection when asked.

export VONDET_TOKEN_SHOP="vdt_… (the shop board's token)"
export VONDET_TOKEN_BLOG="vdt_… (the blog board's token)"

Name: VONDET_TOKEN_SHOP    Value: vdt_… (the shop board's token)
Name: VONDET_TOKEN_BLOG    Value: vdt_… (the blog board's token)

{
  "mcpServers": {
    "vondet-shop": {
      "type": "http",
      "url": "https://vondet.com/api/mcp",
      "headers": {
        "Authorization": "Bearer ${VONDET_TOKEN_SHOP}"
      }
    }
  }
}

{
  "mcpServers": {
    "vondet-shop": {
      "type": "http",
      "url": "https://vondet.com/api/mcp",
      "headers": {
        "Authorization": "Bearer ${VONDET_TOKEN_SHOP}"
      }
    },
    "vondet-blog": {
      "type": "http",
      "url": "https://vondet.com/api/mcp",
      "headers": {
        "Authorization": "Bearer ${VONDET_TOKEN_BLOG}"
      }
    }
  }
}

Always use a different variable name for each board. Using the same name in two repositories makes one of them write to the other's board (any name of capitals, digits and _ works). If you start Claude Code some other way than from a terminal, pass the variable through that launcher. If you registered a connection with the same name by command before, remove it first with claude mcp remove <name> (the local registration takes priority over .mcp.json).
