How to connect Shield
Shield runs locally from a Node.js package published to the npm registry: @bolyra/shield version 0.1.0. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y @bolyra/shield@0.1.0.
In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):
{
"mcpServers": {
"shield": {
"command": "npx",
"args": [
"-y",
"@bolyra/shield@0.1.0"
]
}
}
