# 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:
|
|
1. **Native chat inside Obsidian** — connect any AI provider
|
|
2. **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.
