What is Octobrain?

_MCP Registry: mcp-name: io.github.Muvon/octobrain_ Octobrain gives your AI assistant a long-term memory. Store code insights, architecture decisions, bug fixes, and knowledge - then retrieve them with semantic search in future sessions. Works as a CLI tool or as an MCP server for integration with Claude Desktop and other AI tools. It runs locally over stdio via the published package.

Is Octobrain still maintained?

Yes - as of 2026-08-25, its last commit was 2026-08-22 and it shipped 10+ releases in the last 90 days. We re-verify nightly.

How do I install Octobrain?

Run `npx -y @muvon/octobrain`. The README does not document required environment variables for a basic install. You can also paste the ready-made client config above.

Does Octobrain run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
