KnowBe4 MCP Server
A Model Context Protocol (MCP) server for KnowBe4 security awareness training. Enables AI assistants to manage phishing simulations, training campaigns, user risk scoring, and security awareness reporting.
This is a Model Context Protocol (MCP) server that connects Claude (or any MCP-compatible AI) to your KnowBe4 environment.
Part of the MSP Claude Plugins ecosystem — a growing suite of AI integrations for the MSP stack. Built by MSPs, for MSPs.
Installation
npm install @wyre-ai/knowbe4-mcp
Configuration
Copy .env.example. Stdio and AUTH_MODE=env read the KnowBe4 variables. Gateway mode does not.
| Variable | Required | Description |
|---|---|---|
KNOWBE4_API_KEY | For stdio and AUTH_MODE=env | KnowBe4 API key |
KNOWBE4_REGION | No | API region: us (default), eu, ca, uk, or de |
KNOWBE4_BASE_URL | No | Custom base URL (overrides region) |
MCP_TRANSPORT | No | stdio (default) or http |
AUTH_MODE | No | env (default outside the image) or gateway. The container image and Compose default to gateway. Gateway mode requires X-KnowBe4-API-Key on each /mcp request (X-KnowBe4-Region is optional) and never falls back to KNOWBE4_*. |
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. Compose will not start without it. Never commit a real value. Generate one with openssl rand -hex 32. |
MCP_ALLOW_INSECURE_DEV | No | Set to 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 refuses startup. A known placeholder secret is still refused. |
MCP_HTTP_HOST | No | Bind address when a real CONDUIT_S2S_SECRET is set. Unset keeps 0.0.0.0, which is what the container image sets, so container deploys stay on every interface inside the container. Without a secret the dev bypass binds 127.0.0.1 instead. |
MCP_HTTP_PORT | No | HTTP port. Defaults to 8080. |
/health and /healthz stay unauthenticated and do 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 value is t=<unix seconds>,v1=<hex>, where v1 is HMAC-SHA256 of the exact string t=<unix seconds> keyed by CONDUIT_S2S_SECRET (64 lowercase hex characters). The timestamp must be within 300 seconds of the server clock. A missing or invalid header returns 401. The secret is never written to logs.
import { createHmac } from "node:crypto";
const t = Math.floor(Date.now() / 1000);
const v1 = createHmac("sha256", process.env.CONDUIT_S2S_SECRET)
.update(`t=${t}`)
.digest("hex");
const xGatewayS2s = `t=${t},v1=${v1}`;
In AUTH_MODE=gateway, /mcp also requires X-KnowBe4-API-Key (X-KnowBe4-Region is optional). That header is the only credential source for the request. A request missing it returns 401 and does not read KNOWBE4_API_KEY from the environment.
Usage
Running with Claude Desktop
Add to your Claude Desktop claude_desktop_config.json:
{
"mcpServers": {
"knowbe4-mcp": {
"command": "npx",
"args": ["@wyre-ai/knowbe4-mcp"],
"env": {
"KNOWBE4_API_KEY": "your-knowbe4-api-key"
}
}
}
}
Running with Claude Code (CLI)
claude mcp add knowbe4-mcp \
-e KNOWBE4_API_KEY=your-value \
-- npx -y @wyre-ai/knowbe4-mcp
Docker
The image listens on 0.0.0.0 inside the container (MCP_HTTP_HOST) and defaults to AUTH_MODE=gateway. Publish the port on loopback and pass a real S2S secret. In gateway mode, the KnowBe4 API key arrives on each request as X-KnowBe4-API-Key; it is not read from the environment.
docker build -t knowbe4-mcp .
docker run \
-e CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" \
-p 127.0.0.1:8080:8080 \
knowbe4-mcp
Compose refuses to start when CONDUIT_S2S_SECRET is unset, sets AUTH_MODE=gateway, does not set KNOWBE4_API_KEY or env_file, and publishes 127.0.0.1:8080:8080:
CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" docker compose up
Single-tenant HTTP (AUTH_MODE=env) still requires the S2S secret, then uses KNOWBE4_API_KEY:
docker run \
-e CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" \
-e AUTH_MODE=env \
-e KNOWBE4_API_KEY=your-value \
-e KNOWBE4_REGION=us \
-p 127.0.0.1:8080:8080 \
knowbe4-mcp
Local HTTP without a secret is development-only. It binds 127.0.0.1 and logs a warning. A non-loopback MCP_HTTP_HOST makes startup exit:
MCP_TRANSPORT=http MCP_ALLOW_INSECURE_DEV=1 npm start

Interactive User Card (MCP Apps)
knowbe4_users_get renders as an interactive card in MCP Apps hosts
(Claude Desktop/web) showing the user's risk score, phish-prone percentage,
risk-score trend, and profile details; plain-JSON behavior is unchanged in
other hosts, and the card is read-only (no write round-trip). 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.
