What is MCP?

The Model Context Protocol (MCP) allows Claude and other AI models to discover and use external tools natively. MIDAS ships with a built-in MCP server.

​
Setup

​
1. Install

The MCP server is included in the MIDAS repository under mcp-server/. 
cd mcp-server
npm install

​
2. Configure

Set your API key as an environment variable: 
export PAYMENT_PROTOCOL_API_KEY=pp_your_key
export PAYMENT_PROTOCOL_URL=https://api.midasprotocol.org

​
3. Run

npx tsx index.ts
The server communicates via stdio and is designed to be used with Claude Desktop, Cursor, or any MCP-compatible client.

​

{
