Fizzy MCP

What is Fizzy MCP?

Fizzy MCP is an open-source Model Context Protocol server that enables AI assistants to interact with Fizzy, Basecamp's task management tool.

With Fizzy MCP, your AI can:

• Read your boards and cards - Get full context about your projects

• Create new cards - Add tasks directly from conversation

• Update existing cards - Modify descriptions, tags, and status

• Move cards - Triage cards to columns, postpone, or close them

• Add comments - Leave notes and updates on cards

Quick Start

npx fizzy-do-mcp@latest configure

The wizard will:

1. Detect your installed editors (Claude Desktop, Cursor, etc.)

2. Prompt for your Fizzy API token

3. Configure each editor automatically

Or configure manually:

{
  "mcpServers": {
    "fizzy": {
      "command": "npx",
      "args": ["-y", "fizzy-do-mcp@latest"],
      "env": {
        "FIZZY_TOKEN": "your-fizzy-api-token"
      }
    }
  }
}

Supported Editors

Example Usage

You: What's on my Engineering board?

AI: I found 12 open cards on your Engineering board:

In Progress:
- #234 "Implement user authentication" (assigned to you)
- #235 "API rate limiting"

Needs Triage:
- #240 "Database migration script"
- #241 "Update dependencies"

You: Create a card for adding dark mode support

AI: Created card #242 "Add dark mode support" on the Engineering board.
    Would you like me to add any tags or assign it to someone?
