Claude Code + Muninn: portable CLAUDE.md via MCP
Repo-local context and cross-project memory, without maintaining a file by hand.
Claude Code reads a CLAUDE.md at the root of your project as always-on context. It's fantastic for repo-specific instructions — but it doesn't move with you between repos, and it grows stale the moment your architecture changes.
Muninn complements CLAUDE.md with an MCP endpoint Claude Code can call for the notes that aren't specific to one repo (design principles, product spec, personal preferences). Use both: the file for repo-locked context, Muninn for portable memory.
1. Connect Claude Code to Muninn
Muninn exposes a remote MCP server. Register it once with the CLI:
claude mcp add --transport http muninn https://muninn.ferbutech.no/mcpClaude Code will open a browser window to authorize the connection. After that,list_notes, search_notes, get_note,create_note, and friends are available in every session — from any repo on any machine.
2. Pull a note into CLAUDE.md
Every note in Muninn has a Copy as CLAUDE.md button in the editor toolbar. It puts the note on your clipboard formatted with a title, body, and a source link back to Muninn.
Paste it into CLAUDE.md at the project root:
# Payments architecture
<paste from Muninn>
---
Source: Muninn note ...
Updated: 2026-…You now have the note both in your repo (fast, offline, git-diffable) and in Muninn (portable, editable from any device, searchable from any assistant).
3. When to prefer one over the other
CLAUDE.md | Muninn note | |
|---|---|---|
| Scope | This repo only | Every project / every assistant |
| Editing | In your editor, tracked by git | Muninn web, ChatGPT, Claude, Codex |
| Freshness | Only as fresh as your last commit | Live |
| Great for | Build commands, style rules, "how this repo works" | Architectural memory, personal prefs, decision logs |
Common questions
Do I need Claude Code Pro?
The MCP connection works on any Claude Code plan that supports MCP servers (currently all paid tiers). Muninn charges separately for its notes workspace.
Can I do this without Muninn?
Yes — you can hand-maintain a CLAUDE.md. Muninn just removes the copy-paste treadmill and keeps the same context in ChatGPT and Codex too.
