Nexus (formerly Claudesidian MCP)

Type: Native Obsidian plugin + MCP bridge URL: https://github.com/ProfSynapse/claudesidian-mcp Current name: Nexus MCP for Obsidian Install: .obsidian/plugins/nexus/

What It Does

Full Obsidian plugin with two modes:

Native chat inside Obsidian — connect any AI provider
MCP bridge — expose vault to Claude Desktop, Claude Code, Codex CLI, Gemini CLI, Cursor, Cline

Key Features

Workspace memory — persistent context across sessions stored as JSONL, automatically included in Obsidian Sync
Task management — projects, tasks, blockers, dependencies tracked within vault
Semantic search — search notes + past conversations by meaning
Inline editing — edit selected text in notes
PDF + audio → Markdown — conversion on right-click or auto-on-add
Web page capture — open URL in Obsidian, save as Markdown/PNG/PDF
Mobile support — native chat works on iOS/Android
Two-tool architecture — dedicated tools for read vs write actions

Storage Architecture

Data stored as JSONL files in .obsidian/plugins/nexus/data/. This is included in Obsidian Sync automatically (unlike the .nexus/ folder of v1). SQLite cache is local-only, rebuilt from JSONL on each device.

Relevance to claude-obsidian

Nexus is in a different category — it’s a native TypeScript Obsidian plugin, not a Claude Code skill plugin. The two don’t compete directly, but its workspace memory and task management patterns are cherry-pickable.
