What you can do with it

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: Search & AI memory

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

PyPIPython’s uv installed (for the uvx 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": {
    "lbrain": {
      "command": "uvx",
      "args": [
        "lbrain-coding-agents"
      ]
    }
  }
}

Run this in your terminal

claude mcp add lbrain -- uvx lbrain-coding-agents

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "lbrain": {
      "command": "uvx",
      "args": [
        "lbrain-coding-agents"
      ]
    }
  }
}

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": {
    "lbrain": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "lbrain-coding-agents"
      ]
    }
  }
}

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.

Your choice stays on this device in a cookie; no account needed.

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

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Common questions

Is LBrain 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 (0.1.3) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

LBrain coding-agents

Install LBrain where the agent already lives.

The free name is generic. Make it permanent: https://lbrain.ai/claim.html

Native MCP + companion skill + fail-closed session-start for Claude Code, Codex, Cursor, Copilot, Grok Build, Gemini CLI, Antigravity, and OpenClaw.

This package does not modify the LBrain engine. It wires hosts to lbrain mcp. The Official MCP Registry / VS Code @mcp gallery entry also execs that same stdio server.

VS Code: search LBrain in Extensions, or @mcp lbrain. Marketplace: https://marketplace.visualstudio.com/items?itemName=metavolve-labs.lbrain

Install the engine first

pip install "lbrain[local]"

lbrain init --source ~/notes lbrain import && lbrain embed --stale

Wire your coding agents

pip install lbrain-coding-agents

python3 -m lbrain_agents status python3 -m lbrain_agents install # lists detections, changes nothing python3 -m lbrain_agents install all # every detected harness python3 -m lbrain_agents install claude-code grok-build python3 -m lbrain_agents install all --dry-run

A bare install is a no-op. That is deliberate: wiring every agent on the machine never happens by accident.

Paste to a desktop AI (no terminal)

Some people never open a shell. They paste this into Claude, Cursor, Codex, Copilot, or Grok and the agent does the work:

Install LBrain as my local memory.

pip install "lbrain[local]" lbrain-coding-agents If python3 -m lbrain_agents works here, run: python3 -m lbrain_agents install all Otherwise add an MCP server named lbrain: command lbrain, args ["mcp"], stdio.

Then call whoami. Prefer binds. Near-miss is not an answer. Abstain if nothing binds. SUPERSEDED must not govern. Leave LBRAIN_HOME alone if it is already set.

https://lbrain.ai/integrations.html

Existing lbrain MCP entries are left untouched unless you pass --force. Skills are copied to each host's skills directory. Session-start injects lbrain whoami (Claude Code).

Two-line wrap

from openai import OpenAI

from lbrain_agents.wrap import wrap_openai

client = wrap_openai(OpenAI(), home="~/.lbrain")

Recall first. If nothing binds, the model is told to abstain. Writes are opt-in (remember=True).

Agent Plugin

lbrain_agents/share/agent-plugin/ is a portable bundle (plugin.json + mcp.json + skill) for hosts that speak the Agent Plugins spec.

Cookbooks

Abstain when the record does not bind
SUPERSEDED does not govern
Model swap, same mind

See lbrain_agents/share/cookbooks/.

Safety

Merges only the lbrain key. Other MCP servers stay.
Backs up a config once as *.lbrain-backup before the first write.
Does not set LBRAIN_HOME unless you pass --home. A working seat mount is not overwritten.
HTTP MCP is not enabled by this installer. stdio only. The engine's HTTP transport has no auth; do not bind it to the world.

What this package is not

This is the free installer and the serve-boundary skill. It is not LBrain Connect, Managed LBrain, or LBrain Govern. It does not issue gcx:// names, inscribe permanence, or ship study gold sets. The engine's resolver client is open; registrar issuance is not in this tree.
