Independent studio · MCP-native · Built in the open

The infrastructure beneath your AI tools.

Lyx builds developer-focused tools for a world of many models — from knowing which MCP servers to trust to owning your memory across every AI. The layer below the apps. Composable, portable, yours.

Eight passing filesystem evaluations, retained as a historical snapshot.
Method rung1.v1 — published, versioned, one click from every score.

“Three servers in this category held a passing grade until a symlink probe was written, and then all three returned /etc/passwd. Nothing about those servers changed; our coverage did.”
MCP Verdict, on the limits of its own grades.
We would rather publish what our tests cannot see than round it off. Read the methodology →
01 · What we build

Tools for the MCP era.

Each one solves a different piece of the same problem: the layer between you and the models should be reliable, portable, and yours.

01

MCP Verdict

Snapshot

The neutral registry for MCP servers. Every entry was installed, run against a structured evaluation, and graded on what it actually did — function, reliability, latency, security — then given a written verdict. No vendor paid for placement. The registry is now a retained historical snapshot rather than an active testing service, and every score carries the version and date it was taken.

Lyx Exocortex

In development

A portable, user-owned memory layer: connect your sources once, and any AI can query them through a single MCP endpoint — switch models, lose nothing. The local engine is in active development and nothing is installable yet; the concept page is live.

Lyx Labs

Things we build outside the stack.

For the craft of it. Labs projects keep their own look on purpose — this is where we play, and the house style stops at the door.

Tool Not yet released

Lyx Transcribe

Local-first macOS dictation. Long-press where you are already typing, speak, and the transcript lands in that field. Whisper runs on your Mac through a loopback-only helper — no account, no telemetry, no cloud transcription.

Game Live

Compound

An idle game about compounding systems — rendered as a productivity dashboard. The same forces that govern portfolios and codebases, made tangible and playable.

Game Live

SEED

A number-go-up roguelike where you type the theme of your run — and the Forge names your upgrades after it. Then it hands you a seed, so anyone can play your exact run.

02 · How we build

What we believe.

Three convictions run through everything Lyx ships.

01

Portable beats locked-in

Your tools and your context should travel. We build on open interfaces — MCP first — so switching models never strands you.

02

User-owned by default

Your data lives on infrastructure you control. Least privilege, no credential hoarding, nothing taken wholesale.

03

The boring layer matters

Reliability is a feature. The infrastructure beneath your AI tools should be something you never have to think about.
