O que você pode fazer
- Note Operations — Search globally, read explicit full-markdown note content, and orchestrate the creation of rich hierarchical docs
- Content Mutation — Inject new blocks into existing resources (
add_text), avoiding constant manual copy-pasting - Lifecycle Control — Move outdated research aggressively to the Archive or permanently isolate abandoned drafts in the Trash
- Taxonomy & Tags — List tags, explore bounded nested hierarchies, or completely rename structural tags across thousands of items
Como funciona
1. Subscribe to this server
2. Enter your Bear API Token (interfacing directly with your private local instance)
3. Take absolute control of your linked-thinking graph via Claude or Cursor natively
Say goodbye to breaking focus. Your autonomous agent fetches the precise code snippets or creative writing you saved months ago without breaking context.
Para quem é?
- Developers — inject raw saved configuration blocks directly into your active coding environment
- Writers & Researchers — let the AI read your fragmented thoughts, organize your nested active tags, and assemble pristine drafts
- Productivity Enthusiasts — search the "@todo" tag instantly summarizing all pending personal action items
