README

Memrain

Memrain is a self-hosted memory server for your AI agents. It indexes your markdown notes and your code (TypeScript, Python, Go, Bash, SQL), and it answers any MCP client with cited evidence from hybrid vector + keyword + entity-graph search.

Scattered note and code cards drift in from the left and settle into one connected knowledge graph, which sends cited answers to three waiting agent terminals on the right.

Your notes, index and database stay in your AWS account. Only what an agent retrieves goes to that agent's model.

See it work

Connect once, then ask in plain words. Memrain returns the evidence, cited to the exact page. Your agent writes the answer.

claude mcp add --transport http memrain https://./mcp \
  --header "Authorization: Bearer "

See a full search with --explain

On the host, the CLI runs the same retrieval the MCP `search` tool does, and `--explain` stamps per-signal ranking attribution on every hit:

docker exec deploy-memrain-1 bun run src/cli.ts search "" --k 5 --explain

What you get

You write notes, decisions and code, and six months later neither you nor your agent can find them. Memrain reads all of it once, keeps it searchable, and hands
