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/brain
claude plugin install brain@levirge-brain

Then run /mcp in a session and sign in.

Codex CLI:

codex plugin add levirge/brain

Cline, 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_knowledge with semantic search + reranking; agents cite what they read instead of hallucinating.
  • Write-back that compounds — add_knowledge captures 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:start pulls the right context for a task; /brain:finish persists 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.

Plugin versioning is semver, independent of the Brain server release.
