SUM MCP — By SUM Matrix

An open-source .NET Model Context Protocol (MCP) server by SUM Matrix.
This repo demonstrates how to expose generic developer tools via MCP using SumMatrixTools.

Tools (SumMatrixTools)

• sum.hello — Returns "Hello Sum Matrix!" (optionally greets by name)
• sum.echo — Echo back text
• sum.time.now — Current UTC and (optional) local time by IANA TZ
• sum.time.parse — Parse date/time into ISO + Unix epoch
• sum.uuid.new — Generate a UUID
• sum.math.add — Add two numbers
• sum.math.sum — Sum an array of numbers
• sum.math.avg — Average an array of numbers
• sum.text.slugify — Convert text into a slug
• sum.text.extract_emails — Extract emails from text
• sum.json.validate — Validate JSON and pretty-print it

All tools are stateless and safe (no external network calls).
