Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Checks whether it runs in a sandbox server/src/telemetry/automation-hint.ts:33
const CONTAINER_MARKERS = ['/.dockerenv', '/run/.containerenv'] as const;
In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Reticle — questions

Answers built from our own checks of this server.

Why is there no uptime for Reticle?
Reticle runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @reticlehq/server was installed 1 073 times last week.
How do I connect Reticle?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls @reticlehq/server straight from npm; nothing to host, nothing to sign up for.
How many people use Reticle?
The npm package @reticlehq/server was installed 1 073 times in the last week. Week over week that is -40%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Reticle open source?
No, and the distinction matters: its licence is declared as FSL-1.1-ALv2. That makes it source-available — you can read the code, but the terms are the author's own, not one of the recognised open-source licences. Read them before you build on it.
