# Tools we built, given away.

We hit the same problems our clients do. When the fix is general enough to help someone else's team, we publish it instead of keeping it — free to use, no signup, no upsell.

## qb-mcp

One MCP server for every QuickBooks Online company you manage. QuickBooks MCP is a small, self-hosted Model Context Protocol server that connects all of your QuickBooks Online companies to Claude, Cursor, VS Code and any other MCP client through a single connection. Authorize each company once with Intuit's standard Connect to QuickBooks flow; after that every tool call names the company it should run against. It runs queries, financial reports and record lookups, and it asks before creating or changing anything. Laravel, Inertia and React, shipped as one Docker image.

## tokcodec

A codec for LLM context: the same signal in 30 to 95 percent fewer tokens. Every test run, install log and 2,000-line file an AI coding agent reads lands in its context window, and most of it is filler. tokcodec shrinks those tool results before they land, in graded levels from lossless to outline-only, and always tells the model what it left out. A 21,000-token pytest log becomes 342 tokens with the failure intact. It installs into Claude Code as a skill and hooks with one command.

## lnx-monitor

UniFi Site Manager and network monitoring for managed service providers. LNX Monitor is the network operations platform we run our own NOC on. It syncs sites and devices from UniFi Site Manager, raises incidents when a site goes offline or degrades, and checks servers, websites, SSL certificates and SIP trunks on a schedule, with alert routing, maintenance windows and public status pages built in. Laravel 13, Inertia 2 and Vue 3, shipped as a single Docker image with MySQL and Redis alongside.
