Outline Mcp

Gives Claude a persistent tree-structured knowledge base that survives across sessions. You build nested sections and content nodes with properties, then mark nodes with inject=true to auto-include their content in every conversation. The toc command shows numbered IDs (1, 1-2, 2-1) for easy reference. Includes node_query for filtering by properties, snapshot_create for versioning entire trees, and node_history for per-node change logs. Export to Markdown checklists or JSON for backup. Useful when you need Claude to remember project conventions, coding standards, or runbook procedures without re-pasting them every session. Stores everything in a local JSON file with atomic writes.
