Documentation Overview

abnormal-mcp

MCP server for Abnormal Security — AI-powered threat detection, case management, and email remediation.

Tools

This server uses a decision-tree architecture. Start by calling abnormal_navigate to select a domain, then use the domain-specific tools.

Navigation

Tool	Description
`abnormal_navigate`	Navigate to a domain (threats, messages, remediation, abuse, cases)
`abnormal_back`	Return to domain selection

Threats domain

Tool	Description
`abnormal_threats_list`	List detected threat cases (paginated)
`abnormal_threats_get`	Get full details of a specific threat by ID

Messages domain

Tool	Description
`abnormal_messages_list`	List messages within a threat case
`abnormal_messages_get`	Get detailed message analysis (headers, URLs, attachments, AI analysis)

Remediation domain

Tool	Description
`abnormal_remediation_manage`	Trigger or check remediation actions for a message

Abuse domain

Tool	Description
`abnormal_abuse_list`	List phishing emails reported via the Abuse Mailbox

Cases domain

Tool	Description
`abnormal_cases_list`	List active security investigation cases
`abnormal_cases_get`	Get details of a specific case

Interactive Threat Card (MCP Apps)

abnormal_threats_get renders 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 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.

Authentication

Abnormal Security uses Bearer token authentication.

Standalone (env mode)

server.ts

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)

Terminal

npm install
npm run build
node dist/index.js

HTTP Streamable (for hosted/gateway deployment)

bash

MCP_TRANSPORT=http AUTH_MODE=gateway node dist/index.js

Docker

Terminal

docker compose up

Development

Terminal

npm install
npm run dev          # watch mode
npm test             # run tests
npm run typecheck    # TypeScript type check
npm run build:ui     # rebuild the MCP Apps card bundle (only needed when ui/ changes)
