As a local MCP server: npm package
Built from what Official MCP Registry declares.
claude mcp add --env "CLIENT_PRIVATE_KEY=<YOUR_CLIENT_PRIVATE_KEY>" --transport stdio 402sentinel-mcp -- npx -y @kaditang/402sentinel-mcp
[mcp_servers.402sentinel-mcp]
command = "npx"
args = ["-y", "@kaditang/402sentinel-mcp"]
[mcp_servers.402sentinel-mcp.env]
CLIENT_PRIVATE_KEY = "<YOUR_CLIENT_PRIVATE_KEY>"
{
"mcpServers": {
"402sentinel-mcp": {
"command": "npx",
"args": [
"-y",
"@kaditang/402sentinel-mcp"
],
"env": {
"CLIENT_PRIVATE_KEY": "<YOUR_CLIENT_PRIVATE_KEY>"
}
}
}
}
Replace the values in angle brackets with your own. We show the names of the settings, never values.
Optional settings it also lists: SENTINEL_URL.
We do not store launch arguments. If the server needs any, its own documentation names them.

Is this your plugin?
Add it to your projects and prove you maintain it with a file in its repository, a file on your domain or a DNS record. You get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.
Data comes from the Official MCP Registry (registry.modelcontextprotocol.io), CC0 1.0. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
