Liongard MCP Server

An MCP (Model Context Protocol) server for interacting with the Liongard platform. Provides AI assistants with tools to manage inspectors, systems, metrics, alerts, users, and more through Liongard's API.

One-Click Deployment

Important

Before you click: this server depends on @wyre-technology/node-liongard, which is hosted on the GitHub Packages npm registry. GitHub Packages has no anonymous access — even though the package is public, every npm install needs a token. The cloud builder runs npm install for you, so you must give it one, or the build fails with npm error 401 Unauthorized ... npm.pkg.github.com.

1. Create a GitHub Personal Access Token with the read:packages scope (classic token). Any GitHub account works — you do not need to be a member of the wyre-technology org to read its public packages.
2. Add it as a build variable when prompted by the deploy flow:
   • Cloudflare Workers → set a build variable named NODE_AUTH_TOKEN to your PAT (Workers → Settings → Build → Variables and Secrets).
   • DigitalOcean App Platform → set an encrypted env var named GITHUB_TOKEN with scope Build Time to your PAT (the Dockerfile reads it for the install).

Features

• Decision-tree tool architecture — starts with a navigation tool, then exposes domain-specific tools on demand
• 25 tools across inspectors, systems, metrics, alerts, users, groups, environments, and integrations
• Interactive detection card via MCP Apps (SEP-1865): liongard_detections_get renders as a read-only card in MCP Apps hosts (Claude Desktop/web) with severity/status badges and server-resolved system/environment names — neutral by default, brandable via window.__BRAND__ injection or MCP_BRAND_* env vars (MCP_BRAND_NAME, MCP_BRAND_LOGO_URL, MCP_BRAND_PRIMARY_COLOR, MCP_BRAND_ACCENT_COLOR, MCP_BRAND_BG, MCP_BRAND_TEXT), no rebuild needed
• Dual API version support (v1 and v2)
• 128 tests

Installation

This project depends on @wyre-technology/node-liongard, published to the GitHub Packages npm registry, which requires a token even for public packages. Authenticate once, then install:

# Authenticate npm to GitHub Packages (token needs the read:packages scope)
export NODE_AUTH_TOKEN=$(gh auth token)   # or a PAT with read:packages

npm install

The repo's .npmrc already points the @wyre-technology scope at GitHub Packages and reads the token from NODE_AUTH_TOKEN, so no further config is needed.

Configuration

Set the following environment variables:

Variable	Description
LIONGARD_URL	Your Liongard instance URL
LIONGARD_ACCESS_KEY	API access key
LIONGARD_ACCESS_SECRET	API access secret
