Overview
Description from the maker (original English)
Shared MCP memory for AI agents: knowledge base, skills, todos and agent-to-agent handoffs.

Common questions
Is Levirge Brain 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 in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (26.10.17) reached the registry 17 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Context7, Codebase Memory, Exa

Brain — persistent memory for your AI agents
Your agents forget everything between sessions. Brain doesn't.
Brain is a hosted knowledge base your AI agents read and write over MCP — architecture decisions, runbooks, hard-won gotchas, and agent-to-agent handoffs, searchable from Claude Code, Codex, and any MCP-compatible client. Stop re-explaining your stack to every new session.
Install (2 minutes)
Claude Code:
claude plugin marketplace add levirge/brainclaude plugin install brain@levirge-brain
Then run /mcp in a session and sign in.
Codex CLI:
codex plugin add levirge/brainCline, or any MCP client — remote server, no install:
{ "mcpServers": { "brain": { "type": "streamableHttp", "url": "https://brain.levirge.com/mcp" } } }That is Cline's spelling of the transport type; other clients name it differently. OAuth sign-in on first connect. Details: llms-install.md.
What you get
- Search-first memory —
search_knowledgewith semantic search + reranking; agents cite what they read instead of hallucinating. - Write-back that compounds —
add_knowledgecaptures decisions and fixes once; every future session starts warmer. - Fact lineage — trace any answer back to the documents and atoms it came from (
/brain:lineage). - Agent-to-agent handoffs — a shared inbox between agents and machines: hand work from one session, role, or CLI to another (
/brain:handoff). - Work sessions & context packs —
/brain:startpulls the right context for a task;/brain:finishpersists what was learned. - Self-improving ranking —
feedback(helpful / dead-end verdicts) tunes retrieval to how your team actually works.
Works with your models
Measured in a 10-task × 3-repeat bake-off (fixed judge): Claude Opus-class models ground perfectly, and the bundled search-first contract doubled retrieval compliance on a local 26B. Details in plugins/brain/README.md.
