Quick Demo

An MCP App that brings interactive blue-team security operations directly into Claude, VS Code, and other MCP-compatible AI hosts. Built on the Model Context Protocol with interactive UI extensions that render inline in the conversation.

What are MCP Apps? MCP Apps extend the Model Context Protocol to let tool servers return interactive HTML interfaces — dashboards, forms, visualizations — that render inside the AI conversation. The LLM calls a tool, and instead of just returning text, an interactive UI appears alongside the response.

What This Does

This project provides six interactive security operations tools, each with a rich React-based UI that renders inline when Claude (or another MCP host) calls the tool:

Tool	What It Does
Alert Triage	Fetch, filter, and triage security alerts with AI verdict cards, process tree, and network investigation
Attack Discovery	AI-powered correlated attack chain analysis with confidence scoring, entity risk, and MITRE mapping
Case Management	Create, search, and manage SOC investigation cases with AI-assisted actions
Detection Rules	Browse, tune, and manage detection rules with KQL search and noisy rules analysis
Threat Hunt	ES|QL workbench with clickable entities and a D3 investigation graph
Sample Data	Generate ECS security events for demos across 4 attack chain scenarios

See docs/features.md for a full breakdown of each tool's capabilities.

Quick Start

[!TIP] Just want to try it? Download example-mcp-app-security.mcpb and double-click it. No Node.js, no cloning, no config files.

Claude Desktop handles the rest — during install, fill in your Elasticsearch URL, Kibana URL, and API key. See Creating an API key if you need to generate one first.

For the API key's permissions, see Required permissions (stateful) or Serverless permissions (Elastic Cloud Serverless Security projects). The stateful Quickstart uses Kibana's built-in editor (full-featured) or viewer (read-only) role plus a small companion role for index access — fastest unless you need a fully scripted custom role.

For other hosts (Cursor, VS Code, Claude Code) or building from source, see Installation below.

How It Works

When a user asks Claude to triage alerts or run a threat hunt, Claude calls a model-facing tool on this server. The tool returns a compact text summary to Claude and an interactive React UI that renders inline in the conversation. The UI then calls app-only tools directly for all subsequent interactions — keeping the LLM context small while the UI has full data access.

See docs/architecture.md for details on how views are built, how the UI communicates with the server, and key design decisions.

Telemetry

The MCP App emits anonymised usage events via @elastic/ebt. Shipping is mirrored to the user's Kibana telemetry opt-in — nothing leaves the process unless Kibana reports optIn === true. See docs/telemetry.md for the event catalog, what's collected, and how to opt out.

Skills

The skills/ directory contains Claude Skills — SKILL.md files that teach Claude when and how to use the tools. See docs/setup-skills.md for installation instructions.
