Open source: light-tools
Your agent shouldn’t read 2,000 lines to change five.
Details
light-tools is an open-source MCP server that replaces the built-in file and shell tools used by AI coding agents with token-efficient versions. It ships as a single Go binary, speaks the Model Context Protocol over stdio, and needs no daemon or database. Five tools: light_file, light_bash, light_ssh, light_scp and light_ops. Install with npm install --global @factor-i-o/light-tools, or read more at studio.factor-io.com/light-tools.html and github.com/icediceice/light-tools. Licensed GPL-3.0-or-later.
Tool: AI Inference TCO Calculator
Cost per month, and the month it pays back.
Details
Size an inference workload from the number of people using it, then compare self-hosting, a cloud model API and rented GPU nodes. Returns cost per month, the peak tokens per second you have to serve, and how many months self-hosting takes to pay back its capex. Exact decimal arithmetic, per-provider GPU rates carrying their own confidence tier, and throughput verdicts that say unknown instead of inventing a benchmark. Run the calculator.
How it’s built
Built on Light, our own AI stack.
Details
Factor I O runs on Light — a custom AI-infrastructure stack that lets a small team design, build, test and maintain production software end to end. light-tools is one component of Light, extracted to stand alone.
In development
Backups ransomware can’t reach.
Details
Immutable backup infrastructure for organizations that can’t afford to negotiate with ransomware. Most defenses fail the moment an attacker reaches the backup, so the answer isn’t a smarter alarm — it’s a boundary they physically can’t cross.
