Rybbit

Build Status npm version License: MIT TypeScript MCP SDK

MCP server for Rybbit Analytics — query statistics, errors, users, sessions, funnels, goals, and performance metrics directly from Claude Code or any MCP-compatible client.

---

Why?

Instead of manually checking the Rybbit dashboard, let your AI assistant query analytics data directly:

• "How many users visited the site today?"
• "Show me the top pages by bounce rate this week"
• "What errors occurred in the last hour?"
• "Show user journey from homepage to checkout"
• "Compare browser usage between mobile and desktop"

---

Quick Start

Installation (npx — recommended)

No install needed. Just configure your MCP client to run via npx:

{
  "mcpServers": {
    "rybbit": {
      "command": "npx",
      "args": ["-y", "@nks-hub/rybbit-mcp"],
      "env": {
        "RYBBIT_URL": "https://your-rybbit-instance.com",
        "RYBBIT_API_KEY": "your-api-key"
      }
    }
  }
}

Add this to your ~/.claude/settings.json or project .claude/settings.json.

CLI shorthand:

claude mcp add rybbit -e RYBBIT_URL=https://your-instance.com -e RYBBIT_API_KEY=your-key -- npx -y @nks-hub/rybbit-mcp

Installation (from source)

For development or contributing:

git clone https://github.com/nks-hub/rybbit-mcp.git
cd rybbit-mcp
npm install && npm run build

Then point your MCP config to the local build:

{
  "mcpServers": {
    "rybbit": {
      "command": "node",
      "args": ["path/to/rybbit-mcp/build/index.js"],
      "env": {
        "RYBBIT_URL": "https://your-rybbit-instance.com",
        "RYBBIT_API_KEY": "your-api-key"
      }
    }
  }
}

Usage

Ask Claude Code anything about your analytics data. The MCP tools are automatically available.
