Lians MCP server

Lians is a memory helper for AI coding tools. It lets your AI save small project facts, recall them in a new chat, correct them when things change, and delete them when you ask. It is handy if you use Codex, Claude Code, or Cursor and keep losing context between sessions.

What this MCP server does

You tell your AI something worth remembering, like which Python version your project uses. The AI passes that fact to Lians, which saves it in a small local database file on your computer. Later, in a fresh chat, you ask a question and the AI asks Lians to recall matching facts. Lians sends back the current version of the fact, and the AI uses it in its answer. If a fact changes, you can correct it, and Lians keeps the old version as history instead of pretending it never existed.

What you can do with it

• Save a project fact so a future chat can find it
• Recall saved facts by asking a normal question
• List everything your AI has remembered for a project
• Correct a fact when the project changes
• Forget a fact permanently when you ask
• Recover context in a new chat without replaying the whole conversation

Try asking your AI

• “Remember that this project uses Python 3.12 and pytest.”
• “What Python version and test runner should I use here?”
• “We switched from /v1/orders to /v2/orders. Update that memory.”
• “Forget the note about the old database password.”

What it gives back to you

You get short answers in the chat, built from the facts Lians has stored. When you recall, you see the current fact, and Lians can also show what changed and when. When you list memories, you get a simple list of saved items. When you correct or forget, you get a short confirmation that the change was made.
