Persistent memory for Claude Code with self-hosted Qdrant and Ollama
I built an MCP server that gives Claude Code long-term memory across sessions, backed by infrastructure you control. Every Claude Code session starts from zero, no memory of previous sessions. This server uses mem0ai as a library and exposes 11 MCP tools for storing, searching, and managing memories. Qdrant handles vector storage, Ollama runs embeddings locally (bge-m3), and Neo4j optionally builds a knowledge graph. Some engineering details HN might find interesting: - Zero-config auth: auto-reads Claude Code's OAT token from ~/.claude/.credentials.json, detects token type (OAT vs…
What it does
In the maker’s words, at launch
I built an MCP server that gives Claude Code long-term memory across sessions, backed by infrastructure you control. Every Claude Code session starts from zero, no memory of previous sessions. This server uses mem0ai as a library and exposes 11 MCP tools for storing, searching, and managing memories. Qdrant handles vector storage, Ollama runs embeddings locally (bge-m3), and Neo4j optionally builds a knowledge graph. Some engineering details HN might find interesting: - Zero-config auth: auto-reads Claude Code's OAT token from ~/.claude/.credentials.json, detects token type (OAT vs API key), and configures the SDK accordingly. No separate API key needed. - Graph LLM ops (3 calls per add_memory) can be routed to Ollama (free/local), Gemini 2.5 Flash Lite (near-free), or a split-model where Gemini handles entity extraction (85.4% accuracy) and Claude handles contradiction detection (100% accuracy). Python, MIT licensed, one-command install via uvx. https://github.com/elvismdev/mem0-mcp-selfhosted

- PMPersistent Memory for Claude Code (MCP)Jan 2026 · github.com · ▲7
This is my attempt in building a memory that evolves and persist for claude code. My approach is inspired from Zettelkasten method, memories are atomic, connected and dynamic. Existing memories can evolve based on newer memories. In the background it uses LLM to handle linking and evolution. I have only used it with claude code so far, it works well with me but still early stage, so rough edges likely. I'm planning to extend it to other coding agents as I use several different agents during development. Looking for feedbacks!
- IBI built simple and efficient local memory system for Claude CodeFeb 2026 · github.com · ▲6
I wanted to share a project I have been working on over the past week. It is a simple local memory system that saves your sessions into Markdown files, which can be viewed later. I developed this after using Claude Mem. I really enjoyed working with it, but it was consuming a lot of RAM, and each Claude session was becoming a major resource hog. I also tried other plugins and MCP solutions, but ran into similar issues, either slow performance or concerns about data being sent elsewhere. Because privacy was a big thing for me, I decided to build my own solution that keeps all data local.
