Janus Analytics MCP Server
An MCP server that connects AI coding agents to your Janus analytics. Query your dashboard, events, funnels, and usage directly from Claude Code, Cursor, Windsurf, or any MCP-compatible client.
Setup
1. Get a Janus API key
Sign up at addjanus.ca and create an API key in Settings.
2. Add to your MCP client
Claude Code
claude mcp add janus -- npx -y @janus-analytics/mcp-server
Then set your API key:
export JANUS_API_KEY=jns_your_key_here
Claude Desktop / Cursor / Windsurf
Add to your MCP config file:
{
"mcpServers": {
"janus": {
"command": "npx",
"args": ["-y", "@janus-analytics/mcp-server"],
"env": {
"JANUS_API_KEY": "jns_your_key_here"
}
}
}
}
Config file locations:
- Claude Desktop:
~/Library/Application Support/Claude/claude_desktop_config.json(Mac) or%APPDATA%\Claude\claude_desktop_config.json(Windows) - Cursor: Settings > MCP Servers
- Windsurf:
~/.windsurf/mcp.json
Tools
All tools are read-only — the server never modifies your data.

Example prompts
Once connected, ask your AI agent things like:
- "How's my traffic looking this week?"
- "Show me the top pages from the last 7 days"
- "What's my funnel conversion rate for the signup journey?"
- "Am I close to my usage limit this month?"
- "Which API key is getting the most events?"
