Cognee MCP server

Cognee is a memory helper for your AI. Normally your AI forgets everything once the chat ends. With this connected, you can tell it things, and it will store them and bring them back when you ask.

What this MCP server does

You ask your AI to remember something, like a note, a document or a fact. The AI passes that to this helper program, which sends it to Cognee running on your machine. Cognee stores it in a memory store that uses graphs and vectors (two ways of organising information so it can be searched by meaning, not just by exact words). Later, when you ask a question, the AI asks Cognee to recall what it knows, and you get an answer based on what you saved. You can also ask it to forget things you no longer want stored.

What you can do with it

• Save notes, facts or documents into a memory your AI can reuse later
• Ask your AI to recall something you told it in an earlier chat
• Keep a short-term session memory for a single conversation
• Search an indexed code project to see symbols, dependencies and how a change might affect things
• Delete a dataset or all your stored memory when you no longer need it
• Run the memory helper locally so your data stays on your own machine

Try asking your AI

• “Remember that our team meeting is every Tuesday at 10am and the project lead is Maria”
• “What did I tell you about the Q3 budget last week?”
• “Recall everything I saved about the Johnson account”
• “Forget the dataset called old-notes”

What it gives back to you

You get answers in plain chat text, built from what you previously saved. When you ask it to remember something, it confirms that the item was stored. When you ask it to recall, it gives you the matching facts, notes or documents. When you ask it to forget, it tells you what was removed.

Who it's for

People who want their AI to remember things across chats, and developers who want a searchable memory or code index for their projects.
