SecureNow MCP server

SecureNow

OpenTelemetry instrumentation for Node.js and Next.js applications - send traces and logs to SigNoz or any OTLP-compatible backend.

Official npm package: securenow

🚀 Quick Start

For Next.js Applications

The easiest way to add observability to Next.js!

# Just install - setup is automatic!
npm install securenow

🎉 The installer will automatically:

• Detect your Next.js project
• Create instrumentation.ts (or .js)
• Create .env.local template

Just answer "Y" when prompted!

Then configure your .env.local:

SECURENOW_APPID=my-nextjs-app
SECURENOW_INSTANCE=http://your-signoz-server:4318

Alternative: Use the CLI command

npx securenow init

Done! 🎉 See Next.js Complete Guide for details.

For Node.js Applications (Express, Fastify, NestJS, etc.)

Tracing Only

# 1. Install
npm install securenow

# 2. Set environment variables
export SECURENOW_APPID=my-app
export SECURENOW_INSTANCE=http://your-signoz-server:4318

# 3. Run with preload
NODE_OPTIONS="-r securenow/register" node app.js
# or
NODE_OPTIONS="-r securenow/register" npm start

Tracing + Logging (Recommended)

# 1. Install
npm install securenow

# 2. Set environment variables
export SECURENOW_APPID=my-app
export SECURENOW_INSTANCE=http://your-signoz-server:4318
export SECURENOW_LOGGING_ENABLED=1

# 3. Run with preload (adds logging)
NODE_OPTIONS="-r securenow/register -r securenow/console-instrumentation" node app.js

# Now all console.log/info/warn/error automatically go to SigNoz!
