Hjarni Knowledge Base Integration with Claude via MCP

Hjarni offers a hosted knowledge base with a built‑in MCP server, allowing Claude to fetch and write notes without local tooling. The guide walks through creating a free Hjarni account, connecting Claude via MCP, setting up a folder structure, writing an initial "About me" note, and letting Claude maintain the wiki across devices and LLM clients.

The pattern eliminates the need for Obsidian, local Markdown files, or terminal setup, enabling persistent, multi‑LLM context that compounds across sessions. Claude can read, write, and link notes automatically, making the knowledge base a living, shared brain.

Key benefits include structured folders, write‑back capability, cross‑platform access, and shared context between Claude and ChatGPT.

This approach streamlines knowledge management for developers and teams who want a single source of truth for AI context.
