We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Databases & datasets

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "elen": {
      "command": "npx",
      "args": [
        "-y",
        "@learningnodes/elen-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add elen -- npx -y @learningnodes/elen-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "elen": {
      "command": "npx",
      "args": [
        "-y",
        "@learningnodes/elen-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "elen": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@learningnodes/elen-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Elen safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.3.1) reached the registry 23 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

Elen is an open-source MCP server that records the decisions your coding agent makes, with the limits that bound them, and marks old decisions as superseded. It installs with one npx line, works with Cursor, Claude Code and any MCP client, and keeps decisions in a local SQLite file.

Install

npx -y @learningnodes/elen-mcp@0.3.1

Claude Code

claude mcp add --transport stdio elen -- npx -y @learningnodes/elen-mcp@0.3.1

VS Code

Open this link to install:

vscode:mcp/install?%7B%22name%22%3A%22elen%22%2C%22command%22%3A%22npx%22%2C%22args%22%3A%5B%22-y%22%2C%22%40learningnodes%2Felen-mcp%400.3.1%22%5D%7D

Cursor

Add this to .cursor/mcp.json in your project:

"mcpServers": { "elen": { "command": "npx", "args": ["-y", "@learningnodes/elen-mcp@0.3.1"] } } }

Gemini CLI

Add this to settings.json (~/.gemini/settings.json, or .gemini/settings.json in your project):

"mcpServers": { "elen": { "command": "npx", "args": ["-y", "@learningnodes/elen-mcp@0.3.1"] } } }

Any other MCP client

Use the same mcpServers entry:

"mcpServers": { "elen": { "command": "npx", "args": ["-y", "@learningnodes/elen-mcp@0.3.1"] } } }

Make your agent use it

The tools alone give an agent no habit: it sees what each tool does, but it does not stop mid-task to ask whether a precedent exists. Add the block below to your rules file or system prompt so that searching before a decision and committing after one become part of every session.

# Epistemic Decision Memory Protocol

You must adhere to the Minimal Token Protocol for decisions:

Pointer-First Retrieval: Before making a technical decision, ALWAYS use elen_suggest to retrieve Top-K minimal pointers.
On-Demand Expansion: If a pointer looks relevant, you MUST call elen_expand on that specific ID. Do not hallucinate constraints.
Commiting Atoms: When deciding, use elen_commit. Summarize constraints into plain-text arrays (e.g. "budget < 500ms").
Graph Revision: If a decision invalidates a precedent, you MUST use elen_supersede to advance the graph state.

What it stores

In local mode decisions stay in a SQLite file on your machine (default ~/.elen/decisions.db). Connected mode is optional, needs elen login and an API key, and is in beta.

Tools

Tool	What it does
`elen_commit`	Commits a new decision to the graph, with its constraints as a plain-text list.
`elen_get_competency`	Shows the competency profile for this agent, built from its validated decision history.
`elen_consolidate`	Suggests clusters and duplicate or stale candidates without changing the graph.
`elen_get_context`	Gives an overview of active decision threads grouped by domain, for the start of a session.
`elen_expand`	Expands a decision ID into its full constraints and text.
`elen_incoming`	Lists decisions other people have shared into your workspace. Connected mode, beta.
`elen_log_decision`	Creates a validated Decision Record from constraints, evidence and an answer.
`elen_search_precedents`	Searches validated decisions for precedents.
`elen_status`	Returns the agent, project, database path and counts, to check the namespace before committing.
`elen_suggest`	Retrieves short pointers to prior decisions before you make a new one.
`elen_supersede`	Revises an older decision and marks it superseded by a new one.
`elen_team_search`	Searches team and human decisions visible to your workspace for a topic. Connected mode, beta.
