Let Claude install it for you
Copy this prompt → paste into a new Claude conversation. Claude will open your config file and add the server.
I want to install the ClaudeFinLab MCP server for "Black-Scholes & Local Volatility Options Pricer".
Please add the following to my Claude Desktop config file:
- Mac path: ~/Library/Application Support/Claude/claude_desktop_config.json
- Windows path: %APPDATA%\Claude\claude_desktop_config.json
{
"mcpServers": {
"market_data": {
"url": "https://claudefinancelab.com/market/sse"
}
}
}
Open the file, merge this into the existing mcpServers block (don't overwrite other servers), save it, and tell me when done. I'll restart Claude Desktop after.
Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible AI client.
