What the code does

We have not read this server's code yet, 6 d ago · rules ccca72095570

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.

Builds a file path from a variable src/core/semantic/storage.ts:121

  file(name: typeof FILES[number]): string { return path.join(this.directory, name); }

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.

KnowledgeRail — questions

Answers built from our own checks of this server.

Why is there no uptime for KnowledgeRail?

KnowledgeRail 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 knowledge-rail was installed 34 times last week.

Is KnowledgeRail still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. 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 KnowledgeRail?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls knowledge-rail straight from npm; nothing to host, nothing to sign up for.

How many people use KnowledgeRail?

The npm package knowledge-rail was installed 34 times in the last week. Week over week that is -77%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
