## 📦 Installation
### Option 1: Install from Source (Recommended)
```bash
# Clone the repository
git clone https://github.com/porkll/siyuan-mcp.git
cd siyuan-mcp
# Install dependencies
npm install
# Build the project
npm run build
# Install globally
npm install -g .
```
### Option 2: Install from npm
```bash
# Install globally
npm install -g @porkll/siyuan-mcp
# Or use npx (no installation needed)
npx @porkll/siyuan-mcp
```
After global installation, the `siyuan-mcp` command will be available globally.
## 🔧 Configuration
### Prerequisites
1. **Get your SiYuan API Token:**
- Open SiYuan Note
- Go to Settings → About → API Token
- Copy the token
2. **Ensure SiYuan is running:**
- Default URL: `http://127.0.0.1:6806`
- If using a different port, adjust the `baseUrl` accordingly
### Configure for Cursor
Edit your MCP configuration file at `~/.cursor/mcp.json`:
```json
{
"mcpServers": {
"siyuan-mcp": {
"command": "npx",
"args": [
"-y",
"@porkll/siyuan-mcp",
"stdio",
"--token",
"YOUR_API_TOKEN_HERE",
"--baseUrl",
"http://127.0.0.1:6806"
]
}
}
}
```
**Note**: If you installed globally, you can use `"command": "siyuan-mcp"` instead of `"command": "npx"`.
### Configure for Claude Desktop
Edit the configuration file at:
- **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
```json
{
"mcpServers": {
"siyuan-mcp": {
"command": "npx",
"args": [
"-y",
"@porkll/siyuan-mcp",
"stdio",
"--token",
"YOUR_API_TOKEN_HERE",
"--baseUrl",
"http://127.0.0.1:6806"
]
}
}
}
```
**Note**: If you installed globally, you can use `"command": "siyuan-mcp"` instead of `"command": "npx"`.
### Verify Installation
After configuration, restart your MCP client (Cursor/Claude Desktop) and try:
- "List all my SiYuan notebooks"
- "Search for documents containing 'project plan'"
- "Create a new meeting note in my work notebook"
- "Show me the 5 most recently modified documents"
## 🛠️ Available MCP Tools
Once configured, you can interact with SiYuan through natural language. The server provides 15 essential tools:

- **update_document** - Update (overwrite) document content
- **move_documents** - Move one or more documents to a new location
- **get_document_tree** - Get document tree structure with specified depth
### 📅 Daily Note
- **append_to_daily_note** - Append to today's daily note (auto-creates if needed)
### 📚 Notebook Management

### Usage Examples
Ask your AI assistant naturally:
```
"List all my SiYuan notebooks"
"Search for documents about machine learning"
"Create a new document called 'Project Ideas' in my Work notebook"
"Show me the 10 most recently modified documents"
"Append 'Meeting notes: discussed Q4 goals' to today's daily note"
"Create a snapshot before I make major changes"
"What's the tree structure of my 'Projects' notebook?"
"Move document X to the root of my Work notebook"
"Move documents X and Y under document Z"
```
## 📖 Tool Parameters Reference
### move_documents
Move one or more documents to a new location.
**Parameters:**
- `from_ids` (string[]) - **Required**. Array of document IDs to move
- For a single document, use an array with one element: `["20210101000000-abc1234"]`
- For multiple documents: `["20210101000000-abc1234", "20210102000000-def5678"]`
- `to_parent_id` (string) - **OPTION 1**: Target parent document ID. Documents will be moved under this document as children. Cannot be used together with `to_notebook_root`.
- `to_notebook_root` (string) - **OPTION 2**: Target notebook ID. Documents will be moved to the root (top level) of this notebook. Cannot be used together with `to_parent_id`.
**Important:** You must provide EXACTLY ONE destination: either `to_parent_id` OR `to_notebook_root`.
**Examples:**
```typescript
// Move single document to notebook root
{
from_ids: ["20210101000000-abc1234"],
to_notebook_root: "20210101000000-notebook1"
}
// Move multiple documents under another document
{
from_ids: ["20210101000000-abc1234", "20210102000000-def5678"],
to_parent_id: "20210103000000-parent99"
}
```
### batch_replace_tag
Batch replace all occurrences of a tag across all documents.
**Parameters:**
- `old_tag` (string) - **Required**. Tag name to replace (without # symbol)
- `new_tag` (string) - **Required**. New tag name (without # symbol, use empty string to remove)
**Examples:**
```typescript
// Replace tag
{
old_tag: "project",
new_tag: "work-project"
}
// Remove tag
{
old_tag: "deprecated",
new_tag: ""
}
```
## 🔧 Advanced: Using as TypeScript Library
While primarily designed as an MCP server, you can also use this package as a TypeScript library in your own projects:
```typescript
import { createSiyuanTools } from '@porkll/siyuan-mcp';
// Create an instance
const siyuan = createSiyuanTools('http://127.0.0.1:6806', 'your-token');
// Search operations
const files = await siyuan.searchByFileName('keyword', 10);
const blocks = await siyuan.searchByContent('content', 20);
// Document operations
const content = await siyuan.getFileContent(documentId);
await siyuan.createFile('notebookId', '/path/to/doc', '# Title\n\nContent');
await siyuan.appendToFile(documentId, 'New content');
await siyuan.overwriteFile(documentId, 'Replaced content');
// Daily note
await siyuan.appendToDailyNote('notebookId', 'Today I learned...');
// Notebook operations
const notebooks = await siyuan.listNotebooks();
// SQL queries
const results = await siyuan.search.query(`
SELECT * FROM blocks
WHERE type='d' AND content LIKE '%keyword%'
ORDER BY updated DESC
LIMIT 10
`);
// Direct API access
await siyuan.block.insertBlockAfter(blockId, 'New block content');
await siyuan.document.moveDocument(['doc1', 'doc2'], 'targetNotebookId');
const tree = await siyuan.document.getDocTree('notebookId', 2);
```
### Type Definitions
Full TypeScript types are included:
```typescript
import type {
SiyuanConfig,
SiyuanApiResponse,
Block,
Notebook,
NotebookConf,
DocTreeNode,
SearchOptions
} from '@porkll/siyuan-mcp';
```

- **Protocol**: MCP (Model Context Protocol)
## ❓ FAQ
### How do I get my SiYuan API Token?
1. Open SiYuan Note
2. Go to Settings → About → API Token
3. Copy the token
### How do I find my notebook ID?
Ask your MCP client: "List all my SiYuan notebooks" and it will show IDs.
Or programmatically:
```typescript
const notebooks = await siyuan.listNotebooks();
console.log(notebooks.map(nb => `${nb.name}: ${nb.id}`));
```
### The server isn't working, what should I check?
1. Is SiYuan running? (default: http://127.0.0.1:6806)
2. Is your API token correct?
3. Did you restart your MCP client after configuration?
4. Check the logs in your MCP client
### Can I use a different SiYuan port?
Yes! Just update the `baseUrl` parameter:
```json
"--baseUrl", "http://127.0.0.1:YOUR_PORT"
```
### Does this work with remote SiYuan instances?
Yes! Point `baseUrl` to your remote instance:
```json
"--baseUrl", "http://your-server.com:6806"
```
