# Adding Plugins
ra-mcp can be combined with other MCP servers to create a richer research environment. A common addition is **HTR transcription** — a server that can transcribe handwritten document images using AI.
---
## HTR Transcription Plugin
The [htrflow-mcp](https://huggingface.co/spaces/Riksarkivet/htrflow-mcp) server provides handwritten text recognition (HTR) capabilities, letting your AI assistant transcribe document images directly.
**Server URL:**
```
https://riksarkivet-htrflow-mcp.hf.space/gradio_api/mcp/sse
```
### Claude.ai
1. Open [claude.ai](https://claude.ai) → **:material-puzzle: Integrations** → **Add more integrations...**
2. **Add custom MCP server**
3. Enter:
- **Name:** `htrflow-mcp`
- **URL:** `https://riksarkivet-htrflow-mcp.hf.space/gradio_api/mcp/sse`
4. Click **Add**
### Claude Code
```bash
claude mcp add --transport sse htrflow-mcp https://riksarkivet-htrflow-mcp.hf.space/gradio_api/mcp/sse
```
### Claude Desktop
Add alongside `ra-mcp` in your config file:
```json
{
"mcpServers": {
"ra-mcp": {
"type": "streamable-http",
"url": "https://riksarkivet-ra-mcp.hf.space/mcp"
},
"htrflow-mcp": {
"url": "https://riksarkivet-htrflow-mcp.hf.space/gradio_api/mcp/sse"
}
}
}
```
### VS Code / Cursor / Windsurf
Add to `.vscode/mcp.json`:
```json
{
"mcpServers": {
"ra-mcp": {
"type": "streamable-http",
"url": "https://riksarkivet-ra-mcp.hf.space/mcp"
},
"htrflow-mcp": {
"url": "https://riksarkivet-htrflow-mcp.hf.space/gradio_api/mcp/sse"
}
}
}
```

## Using Both Servers Together
Once both servers are connected, you can combine search and transcription in a single conversation:
1. **Search** for documents using `ra-mcp`
2. **Browse** specific pages to find interesting content
3. **Transcribe** document images using `htrflow-mcp` for pages that need fresh OCR/HTR
