Add this to your VS Code MCP config file. See [VS Code MCP docs](https://code.visualstudio.com/docs/copilot/chat/mcp-servers) for more info.
```json
{
"servers": {
"npm-sentinel": {
"type": "stdio",
"command": "npx",
"args": ["-y", "@nekzus/mcp-server@latest"]
}
}
}
```
### Docker
#### Build
```bash
# Build the Docker image
docker build -t nekzus/npm-sentinel-mcp .
```
#### Usage
You can run the MCP server using Docker with directory mounting to `/projects`:
```json
{
"mcpServers": {
"npm-sentinel-mcp": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"-w", "/projects",
"--mount", "type=bind,src=${PWD},dst=/projects",
"nekzus/npm-sentinel-mcp",
"node",
"dist/index.js"
]
}
}
}
```
For multiple directories:
```json
{
"mcpServers": {
"npm-sentinel-mcp": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"-w", "/projects",
"--mount", "type=bind,src=/path/to/workspace,dst=/projects/workspace",
"--mount", "type=bind,src=/path/to/other/dir,dst=/projects/other/dir,ro",
"nekzus/npm-sentinel-mcp",
"node",
"dist/index.js"
]
}
}
}
```
Note: All mounted directories must be under `/projects` for proper access.
### Usage with Claude Desktop
Add this to your `claude_desktop_config.json`:
```json
{
"mcpServers": {
"npmsentinel": {
"command": "npx",
"args": ["-y", "@nekzus/mcp-server@latest"]
}
}
}
```
Configuration file locations:
- Windows: `%APPDATA%\Claude\claude_desktop_config.json`
