Description

Running the MCP server with Node >= v24.x results in the following error (this capture is with Node v25.2.0):

❯ node /Users/me/Repositories/Clones/Microsoft/SQL-AI-samples/MssqlMcp/Node/dist/index.js
/Users/me/Repositories/Clones/Microsoft/SQL-AI-samples/MssqlMcp/Node/node_modules/buffer-equal-constant-time/index.js:37
var origSlowBufEqual = SlowBuffer.prototype.equal;
^
