rocketcyber-mcp
MCP (Model Context Protocol) server for the RocketCyber Managed SOC platform. Provides read-only access to RocketCyber security data through 10 tools and 3 resources.
Features
- 10 read-only tools covering all RocketCyber API resources, each annotated
readOnlyHint: trueso MCP clients (e.g. Microsoft 365 Copilot) can skip per-call confirmation prompts - 3 MCP resources for quick data access
- Dual transport: stdio (default) and HTTP Streamable
- Lazy SDK initialization on first tool call
- Winston logger with all output routed to stderr
- Connection test tool for validating credentials
One-Click Deployment
[!IMPORTANT] Before you click: this server depends on
@wyre-ai/node-rocketcyber, which is hosted on the GitHub Packages npm registry. GitHub Packages has no anonymous access — even though the package is public, everynpm installneeds a token. The cloud builder runsnpm installfor you, so you must give it one, or the build fails withnpm error 401 Unauthorized ... npm.pkg.github.com.
- Create a GitHub Personal Access Token with the
read:packagesscope (classic token). Any GitHub account works — you do not need to be a member of theWYRE-AIorg to read its public packages.- Add it as a build variable when prompted by the deploy flow:
- Cloudflare Workers → set a build variable named
NODE_AUTH_TOKENto your PAT (Workers → Settings → Build → Variables and Secrets).- DigitalOcean App Platform → set an encrypted env var named
GITHUB_TOKENwith scope Build Time to your PAT (the Dockerfile reads it for the install).
Installation
This project depends on @wyre-ai/node-rocketcyber, 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
npm run build
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.
Configuration
Copy .env.example and set the variables below.
| Environment Variable | Required | Default | Description |
|---|---|---|---|
ROCKETCYBER_API_KEY | For stdio and AUTH_MODE=env | - | RocketCyber API key |
ROCKETCYBER_REGION | No | us | API region: us or eu |
MCP_TRANSPORT | No | stdio | Transport type: stdio or http |
AUTH_MODE | No | env (image and Compose set gateway) | gateway requires X-RocketCyber-API-Key on each /mcp request and never falls back to ROCKETCYBER_*. env uses those variables only after S2S auth succeeds. |
CONDUIT_S2S_SECRET | Yes for HTTP | - | Service-to-service secret. The HTTP server logs an error and exits non-zero when this is empty or a known placeholder (changeme, secret, replace-me, your-s2s-secret, and the other example values). Generate one with openssl rand -hex 32. Compose will not start without it. The value is never logged. |
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 is overridden. A known placeholder secret still refuses to start. |
MCP_HTTP_PORT | No | 8080 | HTTP port (when using http transport) |
MCP_HTTP_HOST | No | 0.0.0.0 when a real secret is set | Bind address when CONDUIT_S2S_SECRET is set. Unset keeps 0.0.0.0. Without a secret, the dev bypass ignores this and binds 127.0.0.1. The container image sets 0.0.0.0. |
LOG_LEVEL | No | info | Log level: error, warn, info, debug |
LOG_FORMAT | No | simple | Log format: json or simple |
/health stays unauthenticated and does not read credentials. 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 check is verifyS2sHeader in src/mcp/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 is 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-RocketCyber-API-Key: $ROCKETCYBER_API_KEY" \
-H "X-RocketCyber-Region: us" \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
In AUTH_MODE=gateway, /mcp also requires X-RocketCyber-API-Key (X-RocketCyber-Region is optional). That header is the only credential source for the request. A missing or blank API key is HTTP 401 and does not fall back to ROCKETCYBER_API_KEY. AUTH_MODE=env still requires the signed X-Gateway-S2S header, then uses ROCKETCYBER_API_KEY from the environment.
Usage
Claude Desktop (stdio)
Add to your Claude Desktop configuration (claude_desktop_config.json):
{
"mcpServers": {
"rocketcyber": {
"command": "node",
"args": ["/path/to/rocketcyber-mcp/dist/entry.js"],
"env": {
"ROCKETCYBER_API_KEY": "your-api-key"
}
}
}
}
HTTP Transport
HTTP refuses to start until CONDUIT_S2S_SECRET is a real secret (not a known placeholder). Publish the port on loopback.
# Single-tenant HTTP. Uses ROCKETCYBER_API_KEY after X-Gateway-S2S verifies.
CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" \
ROCKETCYBER_API_KEY=your-api-key \
MCP_TRANSPORT=http \
npm start
# Local HTTP only, without a service-to-service secret. Always binds 127.0.0.1.
MCP_TRANSPORT=http MCP_ALLOW_INSECURE_DEV=1 npm start
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, RocketCyber credentials arrive on each request as headers; they are not read from the environment.
docker build -t rocketcyber-mcp --build-arg GITHUB_TOKEN="$GITHUB_TOKEN" .
docker run \
-e CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" \
-p 127.0.0.1:8080:8080 \
rocketcyber-mcp
Compose refuses to start when CONDUIT_S2S_SECRET is unset. The gateway service sets AUTH_MODE=gateway, does not inject ROCKETCYBER_API_KEY, and publishes 127.0.0.1:8080:8080:
CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" GITHUB_TOKEN="$GITHUB_TOKEN" docker compose up
Single-tenant HTTP (AUTH_MODE=env) still requires the S2S secret, then uses ROCKETCYBER_API_KEY. It is separate from the gateway Compose service above.
docker run \
-e CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" \
-e AUTH_MODE=env \
-e ROCKETCYBER_API_KEY=your-api-key \
-e ROCKETCYBER_REGION=us \
-p 127.0.0.1:8080:8080 \

Tools
Every tool below only reads data (no tool issues a write to the RocketCyber API), so each is annotated annotations: { readOnlyHint: true } in the tools/list response. MCP clients that honor readOnlyHint — Microsoft 365 Copilot / Copilot Studio among them — use this to skip the per-call confirmation prompt they'd otherwise show before every tool call.
| Tool | Description | readOnlyHint |
|---|---|---|
rocketcyber_test_connection | Test the connection to RocketCyber API | true |
rocketcyber_get_account | Get account information | true |
rocketcyber_list_agents | List monitored agents/endpoints | true |
rocketcyber_list_incidents | List security incidents | true |
rocketcyber_list_events | List security events | true |
rocketcyber_get_event_summary | Get event summary/statistics | true |
rocketcyber_list_firewalls | List firewall devices | true |
rocketcyber_list_apps | List managed apps | true |
rocketcyber_get_defender | Get Windows Defender status | true |
rocketcyber_get_office | Get Office 365 status | true |
