YishenTu/claudian

An Obsidian plugin that embeds Claude Code/Codex as an AI collaborator in your vault

What it solves

Claudian is an Obsidian plugin that integrates AI coding agents (such as Claude Code, Codex, Grok, Opencode, and Pi) directly into your personal knowledge base. It transforms your Obsidian vault into the agent's working directory, allowing the AI to read, write, edit, and search files within your notes, effectively turning your vault into a development environment for your thoughts and documentation.

How it works

The plugin acts as a bridge between Obsidian and various AI coding agent CLIs (Command Line Interfaces). It requires the user to have a compatible agent harness (like Claude Code CLI) and an API provider. The agent then operates on the vault's file system, performing multi-step workflows and file operations.

Who it’s for

Users of Obsidian who want to leverage the power of AI coding agents to automate tasks, manage their notes, and perform complex edits across their entire vault using a chat interface or inline editing tools.

Highlights

  • Multi-Agent Support: Integrates with Claude Code, Codex, Grok, Opencode, and Pi.
  • Vault Integration: Full file read/write, search, and bash capabilities within the vault.
  • Inline Edit: Edit notes directly with a word-level diff preview.
  • Plan Mode: The agent designs and explores before implementing and requesting approval.
  • MCP Servers: Support for connecting external tools via the agent's native MCP configuration.
  • @mention: Ability to mention vault files, subagents, or external directories for context.
  • Collab Mode: Experimental feature for collaborating on shared projects with other users via Git.
  • Slash Commands: Reusable prompt templates and skills via / or $ commands.

    coddingtonbear/obsidian-local-rest-api

    Obsidian‑Local‑REST‑API is an Obsidian plugin that runs a secure HTTPS server exposing a RESTful and MCP‑based API. It lets external scripts or AI agents perform full CRUD on vault files, patch specific headings or front‑matter, search with fuzzy or JsonLogic queries, list/execute Obsidian commands, open notes in the UI, and more—all authenticated via a bearer token. The same capabilities are also reachable via the Model Context Protocol, enabling seamless integration with AI tools like Claude Code, Claude Desktop (via `mcp‑remote`), and Cursor.
