Checked October 20, 2026 against Tana MCP documentation, Tana plans, Outliner local and hosted MCP, Outliner export documentation, Outliner plans. Assistant availability and approvals depend on the client.

First choose which Tana you mean

The main Tana product now focuses on meetings, documents, tasks, and structured team context. Tana Outliner is the separate node-based product with supertags. Use the Outliner documentation when evaluating supertags and node-based workflows.

Both document official hosted MCP endpoints with OAuth. Outliner also keeps its free local desktop server. Both products can use a hosted connection without keeping the desktop app open. Check the plan requirements for the product you choose.

Write review is a real Tana strength

Tana's external write tools normally produce proposals reviewed in Tana. Its documentation also allows explicit auto-approval in supported write tools. That is a concrete difference from relying only on an assistant client's confirmation prompts.

Hjarni writes to named Markdown notes with visible version history and restore. OAuth uses your account's permissions by default; at sign-in or in Settings > Connections, you can limit access to selected folders, make it read-only, or both. The folder-access walkthrough shows how to check this. Manual agent tokens also provide folder and read/write controls for compatible clients. Folder instructions guide behavior; permissions enforce access.

Structure, setup, and costs

Outliner's nodes, fields, and supertags suit people who want to model information. Hjarni uses documents, folders, and tags. The amount of setup depends on the workflow and how much structure you want to define.

Both Tana products offer free plans. Outliner documents hosted MCP as a paid beta while local MCP remains free. Tana lists full MCP with Pro. Hjarni Free includes 25 personal notes and MCP access, with your assistant account separate.

Export needs a media check

Tana Outliner exports Markdown or JSON. The Markdown ZIP omits media files; its documentation explains separate downloads and a helper for localizing linked media. Hjarni's Markdown ZIP importer can accept Markdown, but it does not recreate supertags, views, or the complete Tana graph. Test a sample before migrating.

When to use Tana

  • You prefer Outliner nodes, fields, and supertags
  • You want in-product AI alongside external MCP

When to use Hjarni

  • You prefer Markdown documents in folders

Common questions

Common questions

What is Tana?

Current Tana and Tana Outliner have distinct product and MCP documentation. Their connection methods and tools depend on the product and plan. See official documentation.

Does Tana have an MCP server?

Yes. Current Tana documents hosted OAuth MCP. Tana Outliner separately documents local MCP and a paid hosted OAuth beta. Authentication, availability and tools differ by product and plan.

Tana or Hjarni for AI access?

Both now offer hosted access in documented configurations. Compare tools, permissions and the structure you need: Tana’s structured workflows versus Hjarni’s Markdown folders, team roles and agent-token grants.

Can I import from Tana?

Inspect the export format and test a small conversion. Structured fields, references and outlines need not map directly to Markdown notes. Hjarni’s importer does not promise to preserve another app’s entire data model.
