MCP client setup

Add YIELD INTELLIGENCE to any MCP client (Claude Desktop, Cursor, Windsurf, Cline, etc.):

{
  "mcpServers": {
    "yield-intelligence": {
      "url": "https://mcp.intuitek.ai/yield/mcp"
    }
  }
}

No API key required. No account. 50 free trial calls included.

After adding, your AI assistant gains two tools:

Tool	What it does
`analyze_yield_opportunities`	Scans Treasury yields, dividend ETFs, REITs, preferred stocks, and CDs — surfaces the highest-returning options for your capital and risk tolerance
`optimize_income_portfolio`	Builds or rebalances a diversified portfolio to hit a target monthly income figure, with suggested allocation percentages and rebalancing cadence

Example prompts:

"I have $50k to invest for passive income at moderate risk. What's yielding the most right now?"
"Build me a portfolio targeting $500/month income. I prefer low volatility."
