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.

File ships in the package but is absent from the source [пакет] src/app-store-server.js:1, [пакет] src/cli/auth-cli.js:1, [пакет] src/services/auth-service.js:1 и ещё 71

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.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add flow-nexus -- npx -y flow-nexus

Flow Nexus — questions

Answers built from our own checks of this server.

Why is there no uptime for Flow Nexus?
Flow Nexus 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 flow-nexus was installed 2 497 times last week.
Is Flow Nexus still maintained?
No commits for 13 months. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect Flow Nexus?
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 flow-nexus straight from npm; nothing to host, nothing to sign up for.
How many people use Flow Nexus?
The npm package flow-nexus was installed 2 497 times in the last week. Week over week that is +14%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Flow Nexus open source?
No, and the distinction matters: its licence is declared as Proprietary. 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.
