The thinnest MCP layer that actually works

A short post, because the product is short.

The pitch deck wanted to call Forgeline an "agent operating system." We deleted that line on day twelve. There is already an operating system. It is the one you're running.

What's missing isn't a new OS. It's a narrow, honest wrapper around the one you already have.

What Forgeline is

An MCP server bound to 127.0.0.1. Six tools. One config file.

That's the whole product.

What makes it feel bigger

The client. Point Claude, Notion AI, or ChatGPT at it through a Cloudflare tunnel with bearer auth. Suddenly the assistant you were already talking to can read your notes. Summarize your scrollback. Click the tab you left open last night.

Same six primitives. Composed by the model. It feels bespoke.

That is, we think, the whole point.

Auth is the load-bearing bit

A tunneled local agent without auth is a loaded weapon. We refuse to start if FORGELINE_AUTH_TOKEN is empty. The check has already caught two beta testers, which is a number we're not thrilled about and also the reason the check exists.

What's not on the roadmap

What is

A signed-manifest install flow. Audit logs a human can read. Native bindings for a couple more editors.

All small. All boring. All, we think, the only kind of thing that ages well.
