Give Claude Long-Term Memory

Connect Hjarni to Claude and it can search, create, and organize your notes directly.

Before you start

Claude.ai and Claude iOS

These use OAuth and are the simplest option if you want a managed connector flow.

Claude Desktop, Claude Code, and custom clients

Desktop and Code use the same OAuth flow: Desktop through Connectors, Code from the CLI. Only custom, non-OAuth clients need an API token.

If you're deciding whether Claude should have access to personal notes, team notes, or shared containers, read privacy, permissions, and AI boundaries.

What Claude can do with Hjarni

Once connected, Claude can:

1

Search notes

Full-text search across all your notes, containers, and tags.

2

Create notes

Create new notes with Markdown content, tags, and wiki-links.

3

Organize notes into containers

Place notes in the right folder, or create new folders.

4

Add tags

Tag notes for filtering and grouping.

5

Link notes

Create wiki-links between related notes.

6

Follow your AI instructions

Respect your custom instructions for specific folders and topics.

How to connect Claude to Hjarni

Add from the Claude Connectors Directory

Hjarni is listed in Claude's Connectors Directory as Hjarni notes. This works in Claude.ai, Claude iOS, and Claude Desktop.

  1. Open Hjarni notes in the Claude Connectors Directory, or find it under Directory > Connectors inside Claude.
  2. Click Connect.
  3. Sign in to Hjarni when redirected.
The Hjarni notes listing in Claude's Connectors Directory, showing the Connect button.

That's it. In a conversation, click + and select Connectors to enable Hjarni.

On a managed Team or Enterprise workspace, an admin may need to allow the connector before you can add it. Each member then connects with their own Hjarni account.

Alternative: add Hjarni as a custom connector

Prefer to add the MCP server by URL? Same connection, same OAuth flow. On an individual plan you can do this yourself; in a managed workspace, custom connectors are an admin action too, so an owner may need to add it once from Organization settings.

  1. Open Customize > Connectors in Claude.
  2. Click + then Add custom connector.
  3. Set the name to hjarni and the URL to https://hjarni.com/mcp
  4. Tap Add.
  5. Log in to Hjarni when redirected.
  6. In a conversation, click + and select Connectors to enable Hjarni.
Claude Add custom connector form with name 'hjarni' and URL 'https://hjarni.com/mcp'.

Claude Code

Add Hjarni from the command line. Claude Code handles the OAuth flow in your browser.

claude mcp add --transport http hjarni https://hjarni.com/mcp

This scopes Hjarni to the current project. Add --scope user to make it available across all projects.

Want every session captured as a note? See auto-capture Claude Code sessions for a Stop hook that writes each conversation to Hjarni automatically.

Verify the connection

After connecting, ask Claude one of these:

  • List my recent Hjarni notes
  • Search Hjarni for notes about research
  • Create a note in Hjarni called Claude test

If tools do not appear, check the URL, re-authenticate, or use the MCP troubleshooting section.

What workflows work best

Deep research

Have Claude search your existing notes, synthesize findings, and save new research summaries with links to sources.

Knowledge organization

Ask Claude to review your inbox, organize unprocessed notes into the right containers, and add tags.

Writing with context

Claude can pull relevant notes and use them as source material when helping you write.

Meeting follow-up

After a meeting, have Claude create a note with action items, tag it, and link it to the relevant project notes.

What Claude can and cannot do

Can do

  • Search, read, create, and update notes
  • Delete notes (recoverable from Trash for 30 days)
  • Organize notes in containers
  • Add and manage tags
  • Create wiki-links between notes
  • Follow your custom AI instructions
  • Attach files to notes

Cannot do

  • Remember across conversations (use notes for that)
  • Access notes without you connecting Hjarni first
  • Bypass your permissions or instructions
  • File notes silently. Claude is instructed to confirm the destination folder when it's ambiguous, and deleted notes go to Trash, recoverable for 30 days

Common questions

FAQ

Does Hjarni give Claude long-term memory?

Not automatically. But when you save important information as notes, Claude can search and retrieve it in future conversations. The notes act as your memory. Claude is the interface.

Which Claude plans support MCP?

All of them. Claude.ai and the mobile apps support connectors on Free (one connector), Pro, Max, Team, and Enterprise. Claude Desktop and Claude Code connect through the same OAuth flow, no API token needed.

Can Claude edit existing notes?

Yes. Claude can update the content, tags, container, and status of any existing note.

Does Hjarni include its own AI model?

No. Hjarni is a knowledge base, not an AI model. It gives Claude (or ChatGPT) access to your notes through MCP.
