Atera

Atera MCP Server

Model Context Protocol (MCP) server for interacting with the Atera RMM API. Implements a decision tree architecture for efficient tool discovery and reduced context overhead.

One-Click Deployment

[!IMPORTANT] Before you click: this server depends on @wyre-technology/node-atera, 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-AI 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 .do/app.yaml already declares it).

[!NOTE] The DigitalOcean target builds the full Docker image and runs the complete MCP server over HTTP — this is the recommended path for operators. The Cloudflare Workers target is currently a thin entrypoint stub (the /mcp route returns 501 Not Implemented) and is best suited to gateway-style deployments; for a full self-hosted server prefer DigitalOcean or the prebuilt container image (ghcr.io/wyre-ai/atera-mcp).

Features

• Decision Tree Navigation: Tools are organized by domain (customers, agents, tickets, alerts, contacts). Navigate to a domain first, then use domain-specific tools.
• Lazy Client Loading: The Atera client is only instantiated when first needed, reducing startup time.
• Full API Coverage: Supports customer management, device/agent monitoring, ticket operations, alert handling, and contact management.
• Rate Limit Handling: Built-in rate limiting via the node-atera client (700 req/min).
• Interactive Ticket Card (MCP Apps): atera_tickets_get renders as an interactive card in MCP Apps hosts (Claude Desktop/web) with an in-card "Add comment" round-trip via atera_tickets_add_comment (internal-only by default); plain-JSON behavior is unchanged in other hosts. The card is neutral by default and 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.

Installation

This package is 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 @wyre-ai/atera-mcp

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

Or build from source:

git clone https://github.com/WYRE-AI/atera-mcp.git
cd atera-mcp
npm install
npm run build

Configuration

Copy .env.example and set the variables below.

/health stays unauthenticated and does not read credentials. The stdio transport does not use CONDUIT_S2S_SECRET.

HTTP authentication

With MCP_TRANSPORT=http and CONDUIT_S2S_SECRET set, every /mcp request must include X-Gateway-S2S. The check is verifyS2sHeader in src/s2s-verify.ts: the header value is t=<unix seconds>,v1=<hex>, where the hex is HMAC-SHA256 of the literal string t=<unix seconds> keyed with CONDUIT_S2S_SECRET (64 lowercase hex characters). The timestamp must be within 300 seconds of the server clock. A missing or invalid header returns HTTP 401 before vendor credentials are read.

TS=$(date +%s)
SIG=$(printf 't=%s' "$TS" | openssl dgst -sha256 -hmac "$CONDUIT_S2S_SECRET" -hex | awk '{print $NF}')
curl -sS http://127.0.0.1:8080/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -H "X-Gateway-S2S: t=${TS},v1=${SIG}" \
  -H "X-Atera-API-Key: $ATERA_API_KEY" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

In AUTH_MODE=gateway, /mcp also requires X-Atera-API-Key. That header is the only credential source for the request. With AUTH_MODE=env, the signed request uses ATERA_API_KEY from the environment when the header is absent.

Getting Your API Key

1. Log into Atera as an admin
2. Go to Admin > Data management > API
3. Create an API token (JWT) or copy a legacy API key

JWT tokens (issuer AteraInterop) authenticate with Authorization: Bearer. Legacy static keys authenticate with X-API-KEY. This server selects the header from the key shape, including when the installed node-atera client still sends only X-API-KEY.

Usage

With Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "atera": {
      "command": "npx",
      "args": ["@wyre-ai/atera-mcp"],
      "env": {
        "ATERA_API_KEY": "your-api-key-here"
      }
    }
  }
}

With MCP Gateway

Configure in the gateway registry:

{
  "name": "atera-mcp",
  "command": "node",
  "args": ["/path/to/atera-mcp/dist/index.js"],
  "env": {
    "ATERA_API_KEY": "${ATERA_API_KEY}"
  }
}

Docker

The image listens on 0.0.0.0 inside the container (MCP_HTTP_HOST) and defaults to AUTH_MODE=gateway. Publish the port on loopback and pass a real S2S secret. In gateway mode the Atera API key arrives on each request as X-Atera-API-Key; it is not read from the environment.

# Generate the secret first: openssl rand -hex 32
docker build -t atera-mcp .
docker run \
  -e CONDUIT_S2S_SECRET \
  -p 127.0.0.1:8080:8080 \
  atera-mcp

Compose refuses to start when CONDUIT_S2S_SECRET is unset, defaults AUTH_MODE to gateway, does not inject ATERA_API_KEY, and publishes 127.0.0.1:8080:8080:

CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" docker compose up

Single-tenant HTTP (AUTH_MODE=env) still requires the S2S secret, then uses ATERA_API_KEY:

docker run \
  -e CONDUIT_S2S_SECRET \
  -e AUTH_MODE=env \
  -e ATERA_API_KEY=your-key \
  -p 127.0.0.1:8080:8080 \
  atera-mcp

Local HTTP without a secret is development-only. It binds 127.0.0.1 only and logs a warning. A non-loopback MCP_HTTP_HOST is ignored and the override is logged:

MCP_TRANSPORT=http MCP_ALLOW_INSECURE_DEV=1 npm start

Decision Tree Architecture

This server uses a navigation-based approach to tool discovery:

1. Start: Only atera_navigate tool is available
2. Navigate: Call atera_navigate with a domain (customers, agents, tickets, alerts, contacts)
3. Tool list refresh: The server declares tools.listChanged and sends notifications/tools/list_changed so the client re-fetches tools/list
4. Domain Tools: After that refresh, domain-specific tools are available
5. Back: Use atera_back to return to domain selection (this also sends notifications/tools/list_changed)

This architecture:

• Reduces tool list size for better LLM performance
• Groups related operations logically
• Minimizes context window usage
