MCP AI agents (Claude, Cursor, etc.) MCP Setup Guide
REST API Direct HTTP requests from any app REST API Reference

What is MCP?

Model Context Protocol (MCP) is an open standard for connecting AI models to external tools and data sources. PlusE implements MCP to provide financial data tools that your AI can call during conversations.

Instead of fetching and parsing raw market data, your AI agent can call PlusE's pre-built tools to get structured financial insights.

MCP Architecture

Quick Start (MCP)

  1. Get an API key - Sign up at console.plusefin.com

  2. Configure your MCP client - Add PlusE server to your client:

    {
  "mcpServers": {
    "plusefin": {
      "httpUrl": "https://mcp.plusefin.com/mcp/?apikey=YOUR_API_KEY"
    }
  }
}

  3. Start using tools - Your AI can now call financial data tools:

    • get_ticker_data("AAPL") - Company overview and metrics
    • get_holdings("SPY") - ETF holdings and sector allocation
    • get_news_sentiment("TSLA") - News sentiment analysis

See MCP Client Setup for detailed configuration.

Quick Start (REST API)

If you prefer direct HTTP requests:

curl -H "Authorization: Bearer YOUR_API_KEY" \
  "https://mcp.plusefin.com/api/tools/ticker/AAPL"

See REST API Reference for all endpoints.
