Avanan

License Node.js

A Model Context Protocol (MCP) server for Check Point Avanan (Harmony Email & Collaboration). Enables AI assistants to manage security events, investigate threats, and handle multi-tenant MSP operations across your email security environment.

This is a Model Context Protocol (MCP) server that connects Claude (or any MCP-compatible AI) to your Check Point Avanan environment.

Part of the MSP Claude Plugins ecosystem — a growing suite of AI integrations for the MSP stack. Built by MSPs, for MSPs.

Features

• Interactive Security Event Card (MCP Apps): hec_get_event renders as a read-only interactive card in MCP Apps hosts (Claude Desktop/web) showing severity, state, platform, and remediation status; neutral by default, brandable via window.__BRAND__ injection or MCP_BRAND_* env vars; plain-JSON behavior is unchanged in other hosts

Installation

npm install @wyre-ai/avanan-mcp

Configuration

Copy .env.example and set the variables below. Leave CONDUIT_S2S_SECRET empty in that file.

Variable	Required	Description
CHECKPOINT_CLIENT_ID	For stdio and AUTH_MODE=env	Checkpoint/Avanan OAuth2 client ID
CHECKPOINT_CLIENT_SECRET	For stdio and AUTH_MODE=env	Checkpoint/Avanan OAuth2 client secret
CHECKPOINT_REGION	No	API region (us, eu, au, in). Auto-detected from the JWT when omitted.
MCP_TRANSPORT	No	stdio (default) or http
AUTH_MODE	No	gateway (Docker image and Compose default) or env. Gateway mode requires X-Checkpoint-Client-Id and X-Checkpoint-Client-Secret on each /mcp request and never falls back to CHECKPOINT_*. env uses those variables only after S2S auth succeeds.
CONDUIT_S2S_SECRET	Yes for HTTP	Service-to-service HMAC secret. The HTTP server logs an error and exits non-zero when this is empty or a known placeholder (changeme, replace-with-a-real-secret, your-s2s-secret, and the other public example values). MCP_ALLOW_INSECURE_DEV=1 does not accept a placeholder. Compose will not start without it. Never commit a real value. The value is never logged. Generate one with openssl rand -hex 32.
MCP_ALLOW_INSECURE_DEV	No	Set to exactly 1 only for local development to start HTTP without CONDUIT_S2S_SECRET. The process logs a warning, does not enforce X-Gateway-S2S, and binds 127.0.0.1 only. A non-loopback MCP_HTTP_HOST (including 0.0.0.0) is overridden and the override is logged.
MCP_HTTP_HOST	No	Bind address when MCP_TRANSPORT=http. Defaults to 127.0.0.1. A configured secret honors this value. The container image sets 0.0.0.0.
MCP_HTTP_PORT	No	HTTP port. Defaults to 8080.

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

HTTP authentication

With MCP_TRANSPORT=http and a real CONDUIT_S2S_SECRET, every /mcp request must include X-Gateway-S2S. 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-Checkpoint-Client-Id: your-client-id' \
  -H 'X-Checkpoint-Client-Secret: your-client-secret' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

In AUTH_MODE=gateway (the image and Compose default), /mcp also requires X-Checkpoint-Client-Id and X-Checkpoint-Client-Secret. Those headers are the only credential source for that request. A request missing either one returns 401 and does not fall back to CHECKPOINT_CLIENT_ID / CHECKPOINT_CLIENT_SECRET in the process environment.

Single-tenant HTTP (AUTH_MODE=env) still requires a valid X-Gateway-S2S header, then uses CHECKPOINT_CLIENT_ID and CHECKPOINT_CLIENT_SECRET when the request does not carry those headers.

Usage

Running with Claude Desktop

Add to your Claude Desktop claude_desktop_config.json:

{
  "mcpServers": {
    "avanan-mcp": {
      "command": "npx",
      "args": ["@wyre-ai/avanan-mcp"],
      "env": {
        "CHECKPOINT_CLIENT_ID": "your-checkpoint-client-id"
        "CHECKPOINT_CLIENT_SECRET": "your-checkpoint-client-secret"
      }
    }
  }
}

Running with Claude Code (CLI)

claude mcp add avanan-mcp \
  -e CHECKPOINT_CLIENT_ID=your-value \
  -e CHECKPOINT_CLIENT_SECRET=your-value \
  -- npx -y @wyre-ai/avanan-mcp

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, Checkpoint credentials arrive on each request as headers; they are not read from the environment.

docker build -t avanan-mcp .
docker run \
  -e CONDUIT_S2S_SECRET=your-s2s-secret \
  -p 127.0.0.1:8080:8080 \
  avanan-mcp

Compose refuses to start when CONDUIT_S2S_SECRET is unset, sets AUTH_MODE=gateway, does not inject CHECKPOINT_CLIENT_ID or CHECKPOINT_CLIENT_SECRET, and publishes 127.0.0.1:8080:8080:

CONDUIT_S2S_SECRET=your-s2s-secret docker compose up

Single-tenant HTTP (AUTH_MODE=env) still requires the S2S secret, then uses CHECKPOINT_CLIENT_ID and CHECKPOINT_CLIENT_SECRET. Keep that off the gateway Compose service:

docker run \
  -e CONDUIT_S2S_SECRET=your-s2s-secret \
  -e AUTH_MODE=env \
  -e CHECKPOINT_CLIENT_ID=your-value \
  -e CHECKPOINT_CLIENT_SECRET=your-value \
  -e CHECKPOINT_REGION=us \
  -p 127.0.0.1:8080:8080 \
  avanan-mcp

Local HTTP without a secret is development-only. It binds 127.0.0.1 even when MCP_HTTP_HOST is 0.0.0.0 or localhost, and logs a warning. A known placeholder secret still refuses to start:

MCP_TRANSPORT=http MCP_ALLOW_INSECURE_DEV=1 npm start
