Cursor & Windsurf - EventGraph

Overview

Both Cursor and Windsurf support MCP servers, letting you bring live EventGraph data into your development workflow. Query markets, pull price data, and build trading-adjacent applications without ever leaving your editor.

Cursor Setup

1. Complete the MCP quickstart

MCP Quickstart →

Set up the EventGraph MCP server (5 min)

2. Open Cursor MCP settings

Go to Cursor Settings → Features → MCP Servers (or edit ~/.cursor/mcp.json directly).

3. Add EventGraph

{
  "mcpServers": {
    "eventgraph": {
      "command": "node",
      "args": ["/absolute/path/to/eventgraph-mcp/server.js"],
      "env": {
        "EVENTGRAPH_API_KEY": "eg_live_your_key_here"
      }
    }
  }
}

4. Restart Cursor

After restarting, open the chat panel (Cmd+L) and you should see EventGraph tools available.

Windsurf Setup

1. Open Windsurf MCP config

Edit ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "eventgraph": {
      "command": "node",
      "args": ["/absolute/path/to/eventgraph-mcp/server.js"],
      "env": {
        "EVENTGRAPH_API_KEY": "eg_live_your_key_here"
      }
    }
  }
}

2. Restart Windsurf

Cascade (Windsurf’s AI) will pick up the new server on restart.

Other MCP clients

The same config pattern works for any MCP-compatible client:

Client	Config file
Continue	`.continue/config.json` → `mcpServers` block
VS Code (MCP extension)	`.vscode/mcp.json`
Zed	`~/.config/zed/settings.json` → `context_servers`
Claude Code	`claude mcp add` CLI command

For Claude Code (CLI):

claude mcp add eventgraph \
  --command node \
  --args /path/to/eventgraph-mcp/server.js \
  --env EVENTGRAPH_API_KEY=eg_live_your_key

Use cases in a coding context

Building a trading dashboard?

Pull the current order book for the top 5 most-traded Kalshi markets
and generate TypeScript types for the response structure.

Writing analysis scripts?

Fetch price history for market ID abc123 over the last 30 days
and generate a Python script to plot it with matplotlib.

Researching an API integration?

Search for all active sports markets and show me the structure
of a market object so I can design my database schema.

Troubleshooting

Tools not showing in Cursor

Check Cursor version — MCP requires Cursor 0.43+
Verify the JSON in ~/.cursor/mcp.json is valid
Use an absolute path (not ~ or relative paths) for server.js
Check Cursor Settings → MCP to see server status

Server disconnects mid-conversation

This usually means an unhandled error in the server. Check your Node.js version (node --version should be 18+) and ensure the server.js file is complete and unmodified.
