MCP (Model Context Protocol) Overview

What is MCP?​

The Model Context Protocol (MCP) is a standardized way for AI models to securely interact with external tools, services, and data sources.
Within Javelin, MCP acts as a bridge between LLMs and external systems, enabling richer AI capabilities while enforcing enterprise-grade security, policy compliance, and continuous vulnerability checks.

Key Benefits​

1. Enhanced AI Capabilities​

  • Tool Integration – Connect AI to APIs, databases, and enterprise services.
  • Controlled Access – Enable/disable specific tools per MCP server, ensuring only approved tools are usable
  • Application-Centric Usage – All MCP interactions are tied to the Application that invoked them, keeping usage, logs, and policies scoped to the right context.

2. Enterprise Security​

  • Policy Enforcement – Apply filters (e.g., Malicious Instruction Injections, Data Protection).
  • Audit Trail – Every request and tool invocation is logged.
  • Vulnerability Scan – Whenever you enable/disable a tool or open the Tools tab, Javelin automatically runs a vulnerability scan to detect security risks in that tool.

3. Operational Efficiency​

  • Simple Management – Easy setup of servers and tool configs.
  • Monitoring & Analytics – Usage tracking, vulnerability status, and performance insights.

Core Components​

  1. MCP Registry – Central place to register and configure MCP servers.
  2. Policy Engine – Enforces Malicious Instruction Injections, Data Protection, and other filters.
  3. Tool Definitions – List of tools available per server.
  4. Vulnerability Scan – Continuous vulnerability assessment for registered tools.
  5. Chronicles & Audit – Request/Response logs for compliance.

Data Flow​

  1. Request initiated by AI (e.g., call to an external tool).
  2. Javelin applies policy filters.
  3. Tool is selected from MCP registry.
  4. Request executed on MCP server.
  5. Response returned, filtered, and logged.
