Every couple of weeks, Mark walks through the best questions, workarounds, and discoveries from the Tana community Slack. Week 12 covers a fallback way to connect a coding agent, a more advanced automation trigger, a refresher on hiding fields, and the reliable way to copy large content out of Tana.
Connect a coding agent with a personal API token [0:00]
The docs cover the recommended way to link Codex, Claude Code, or Gemini to Tana via the local API MCP. For agents not covered there (Open Code, Open Router), or when a connection keeps dropping, there's a fallback: create a personal API token under API tokens, then point an mcp.json file at the local MCP address with a bearer authorization header holding that token. Keep the token private, ideally behind an environment variable, and never paste it where others could see it. Your coding agent can write the config for you.
Trigger commands from a field change [2:50]
Beyond the familiar tag triggers (on added, on removed, on checked), fields have their own automations. Debug a field with command + K, scroll to its automations, and you'll find on child added and on child removed. So when you set a value in a field, you can fire a command, for example automatically adding a status-report tag whenever a project is set. Note the context: an on-child-added command runs on the child by default, so step up to the field's owner if you want it to act on the node itself. It's powerful but can be too sensitive for every situation.
Hide-field conditions [5:40]
A refresher distinct from the truly hidden metadata fields covered in an earlier review. Run command + K then set hide field conditions to choose when a field collapses to the top of a node: always, when empty, and more. Hide when empty, for instance, keeps a field tucked away until it has a value, cutting visual clutter without removing the field.
Get content out of Tana [7:07]
command + K then copy as offers markdown, Tana Paste, and markdown without fields and tags, but these can miss content buried in deeply nested layers or search nodes. For everything nested under a node, use command + K then copy full content to clipboard. It's the one to reach for when copying a long meeting transcript, where the lighter methods report the content is too big. With a lot of content, expect Tana to lag briefly while it copies.
