alliotools-mcp

alliotools-mcp

Privacy-first MCP server for allio Tools β€” 176+ utilities that run entirely on your machine.

No API keys. No accounts. No data leaves your device.


What is this?

Model Context Protocol (MCP) is an open standard that lets code editors and chat applications connect to external tool servers. This package brings allio Tools' calculators, converters, developer tools, text utilities, and date/time tools directly into any MCP-compatible client β€” running entirely as a local process on your machine.

Privacy first: Every tool in this server computes results locally in Node.js. Nothing is sent to allio.tools or any third-party service. The only exceptions are the network tools (marked with 🌐), which make external calls by design β€” for example, a DNS lookup must contact a DNS server.

Privacy

This MCP server was built with privacy as the primary design constraint.

  • Local tools (all calculators, converters, developer tools, text tools, date/time tools): All computation happens in the Node.js process on your machine. No network requests are made. No data is transmitted anywhere.

  • Network tools (DNS lookup, HTTP header checker, website status, IP lookup, OG preview): These tools exist to query external resources β€” that's their purpose. The request goes directly from your machine to the target. allio Tools never sees the request.

  • No telemetry. No analytics. No usage tracking. No crash reporting.

  • Open source. You can read every line of this code and verify it yourself.


Using with your AI

Once installed, just ask naturally:

  • "Calculate compound interest on $10,000 at 5% for 20 years, compounded monthly"

  • "Convert 180 lbs to kg"

  • "How many days between March 15 2024 and November 30 2024?"

  • "Generate 5 UUIDs"

  • "What is the SHA-256 hash of 'hello world'?"

  • "Convert 9:30 AM New York time to London time"

  • "Look up DNS records for allio.tools"

  • "Is https://example.com up?"
