ymigo-mcp

Ymigo MCP Server — Flow coverage analysis, test table generation, and flow management — directly inside Claude Desktop or Claude Code.

Claude is probabilistic. Ymigo is mathematical. Together they give you both.

What you can do

Analyze from a description or code

Describe your logic in plain English (or point Claude to a code file) — Claude builds the flow and runs the analysis. No manual JSON required.

"Analyze the test coverage of my payment flow" "Read src/auth/login.py and tell me what paths aren't tested"

Analyze flows saved in your Ymigo account

"Analyze my Payment Flow" — Claude fetches the flow and scenarios from your account automatically.

Save flows to Ymigo and get a visual link

After Claude builds or analyzes a flow, ask it to save it:

"Save this flow to Ymigo so I can see it visually"

Claude creates the flow in your account and returns a direct link to open it in the browser.

Export test tables for Jira / Confluence

"Export the test table as CSV"

Claude returns a structured table with test cases, coverage stats, and uncovered transitions — ready to paste.

Requirements

• Python 3.10+
• Claude Desktop or Claude Code

Setup (5 minutes)

1. Install

pip install ymigo-mcp

2. Get your API key

Go to ymigo.app → sign in → click your name (top right) → Generate API Key

You'll get a key like ymigo_xxxxxxxxxxxxxxxx.

3. Add to Claude Desktop config

Open the config file for your OS:

• Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Add the following (create the file if it doesn't exist):

{
  "mcpServers": {
    "ymigo": {
      "command": "ymigo-mcp",
      "env": {
        "YMIGO_API_KEY": "ymigo_xxxx"
      }
    }
  }
}

Replace ymigo_xxxx with your actual key.

4. Restart Claude Desktop

Fully quit Claude Desktop (including from the system tray) and reopen it.

5. Verify it's connected

In Claude Desktop, look for the hammer icon (Tools) at the bottom of the chat. Click it — you should see the Ymigo tools listed.
