Fizzy-MCP

An MCP (Model Context Protocol) server for Fizzy, Basecamp's open-source Kanban tool.

What is MCP?

Model Context Protocol lets AI assistants (like Claude) use external tools. This server gives Claude the ability to manage your Fizzy boards and cards.

Quick Start

1. Install

git clone https://github.com/clawdcraft/fizzy-mcp.git
cd fizzy-mcp
npm install
npm run build

2. Get a Fizzy API Token

Open your Fizzy instance (e.g., http://localhost:3000)
Click your avatar → My profile
Go to Access Tokens
Click Generate a new access token
Enter a description (e.g., "MCP Server")
Select Read + Write permission
Copy the token (you won't see it again!)

3. Configure Your Claude Client

Claude Code (macOS/Linux)

Edit ~/.claude.json:

{
  "mcpServers": {
    "fizzy": {
      "command": "node",
      "args": ["/full/path/to/fizzy-mcp/dist/index.js"],
      "env": {
        "FIZZY_URL": "http://localhost:3000",
        "FIZZY_TOKEN": "your-api-token-here",
        "FIZZY_ACCOUNT_ID": "1"
      }
    }
  }
}

Claude Desktop (macOS)

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "fizzy": {
      "command": "node",
      "args": ["/full/path/to/fizzy-mcp/dist/index.js"],
      "env": {
        "FIZZY_URL": "http://localhost:3000",
        "FIZZY_TOKEN": "your-api-token-here",
        "FIZZY_ACCOUNT_ID": "1"
      }
    }
  }
}

Then restart Claude.

4. Use It

Ask Claude things like:

"List my Fizzy boards"
"Create a card called 'Fix login bug' on the Ravenus board"
"Move card 15 to Done"
"Add a comment to card 12"

Remove tag "feature" from card 12

Tags are created automatically if they don't exist.

Development

# Install dependencies
npm install

# Build
npm run build

# Watch mode
npm run dev

Testing Manually

export FIZZY_URL="http://localhost:3000"
export FIZZY_TOKEN="your-token"
export FIZZY_ACCOUNT_ID="1"

# List tools
echo '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' | node dist/index.js

# Call a tool
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"fizzy_list_boards","arguments":{}}}' | node dist/index.js

Troubleshooting

406 Not Acceptable

Check that FIZZY_TOKEN is set and valid
Verify the token has Read + Write permissions

Connection refused

Ensure Fizzy is running at the configured URL
Check the port matches your Fizzy setup

Card not found

Card IDs are the card number (e.g., 11), not the CUID
