SiYuan Sisyphus MCP & CLI

Latest: v0.4.13 — Adds explicit MCP HTTP bind address selection, tightens settings UI behavior, and moves the CLI short alias from siyuan to sisyphus. CLI is now v0.1.16.

What It Is

SiYuan Sisyphus lets AI agents safely read, search, edit, and organize your SiYuan workspace.

It ships as both a SiYuan plugin and a standalone CLI:

• MCP plugin: connect SiYuan to Claude Desktop, Claude Code, Codex, Cursor, Cherry Studio, Cline, and other MCP-capable clients.

• CLI siyuan-sisyphus: let agents, terminals, and scripts call SiYuan directly through short commands.

Both entry points use the same permission model and the same underlying SiYuan operations.

Why It Is Different

• Git-like document timeline: create named timeline nodes for a document, compare historical snapshots with the current state, and roll back when needed.

• AI-friendly note access: the fs tool lets agents work with human-readable paths such as /Notebook/Project/Note, hiding block IDs and document-tree details when they are not needed.

• MCP and CLI together: use MCP for multi-step agent workflows, or CLI for lightweight terminal and script automation.

• Notebook-level safety: give each notebook its own access level: none, r, rw, or rwd.

• Low-context tool design: 100+ SiYuan capabilities are grouped into 12 action-routed tools, with detailed help available only when the agent asks for it.

• Practical connection setup: the plugin settings page provides copy-ready connection snippets for common AI clients and deployment styles.

Git-Like Document Timeline

The timeline feature gives ordinary SiYuan documents a source-control-style safety layer:

• create named timeline nodes for the current document;

• compare a historical snapshot with the current document;

• switch between unified diff and split diff;

• use a minimap-style change navigator and collapse unchanged blocks;

• roll back the whole document, or restore supported parsed blocks individually.

This is a document-focused timeline built on SiYuan snapshots. It is intentionally not a full Git replacement or a complete source-control workflow.

MCP And CLI Entry Points

Use MCP when an AI client should discover tools and combine them across a longer task. This is the best fit for agent workflows that need to search, read, edit, inspect databases, and verify results.

Use CLI when a terminal command is enough. It avoids long tool schemas in the model context and works well for scripts, automation, and small one-shot tasks.

npm i -g siyuan-sisyphus
siyuan-sisyphus init
sisyphus notebook list

Safety Model

SiYuan Sisyphus is designed around explicit user control:

• each notebook can be read-only, writable, deletable, or hidden from AI;

• dangerous actions such as delete, move, replace, and asset upload are treated separately;

• MCP and CLI share the same core behavior, so switching entry points does not create a second permission model;

• remote and Docker use cases go through the SiYuan HTTP API instead of assuming direct access to your local workspace files.

Quick Start

1. Install the plugin from the SiYuan marketplace, or follow the source installation guide.

2. Open Plugin -> SiYuan Sisyphus MCP & CLI -> Settings.

3. Choose MCP or CLI in the connection page.

4. Copy the generated client configuration, or initialize the CLI with siyuan-sisyphus init.

5. Verify with a read-only task such as listing notebooks or reading the SiYuan version.
