Claude Code

Claude Code is Anthropic's official CLI tool for Claude. It uses a different configuration approach than GUI-based editors.

Installation

Claude Code uses CLI commands to manage MCP servers, not JSON config files.

$ claude mcp add fizzy -- npx -y fizzy-do-mcp@latest

Added MCP server: fizzy

Set Environment Variable

Claude Code needs your Fizzy token as an environment variable:

# Add to ~/.bashrc, ~/.zshrc, or ~/.profile
export FIZZY_TOKEN="your-fizzy-api-token"

# Reload your shell
source ~/.bashrc

Or for a single session:

FIZZY_TOKEN="your-token" claude

Managing MCP Servers

List Configured Servers

$ claude mcp list

fizzy: npx -y fizzy-do-mcp@latest

Remove a Server

$ claude mcp remove fizzy

Removed MCP server: fizzy

Verify It Works

Start Claude Code and try a Fizzy command:

$ claude

You: What Fizzy boards do I have?

AI: I found 2 boards in your Fizzy account:
    - Engineering (8 open cards)
    - Personal (12 open cards)

Troubleshooting

"FIZZY_TOKEN environment variable is required"

Make sure your token is exported in your current shell session:

$ echo $FIZZY_TOKEN
your-fizzy-api-token

If empty, set it and restart Claude Code.

"Command not found: claude"

Ensure Claude Code is installed and in your PATH:

npm install -g @anthropic-ai/claude-code

MCP server not loading

Try removing and re-adding:

claude mcp remove fizzy
claude mcp add fizzy -- npx -y fizzy-do-mcp@latest
