Interactive Threat Card (MCP Apps)
abnormal_threats_getrenders as an interactive threat card in MCP Apps hosts (Claude Desktop/web): subject, sender, attack classification, remediation status, and the messages in the threat. The card is read-only — remediation stays a deliberate, model-mediated action. Plain-JSON behavior is unchanged in other hosts. Neutral by default, brandable viawindow.__BRAND__injection orMCP_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.
Authentication
Abnormal Security uses Bearer token authentication.
Standalone (env mode)
export ABNORMAL_API_TOKEN=your-api-token
node dist/index.js
Generate your token in the Abnormal portal under Settings > Integrations > API.
Gateway mode
When deployed behind the MCP gateway, set AUTH_MODE=gateway. The gateway injects the Authorization: Bearer {token} header automatically on each request.
Running
stdio (for Claude Desktop)
npm install
npm run build
node dist/index.js
HTTP Streamable (for hosted/gateway deployment)
MCP_TRANSPORT=http AUTH_MODE=gateway node dist/index.js
Docker
docker compose up
Development
