If you’ve been paying attention to AI development over the past year, you’ve probably noticed something: AI agents aren’t just chatbots anymore. They’re connecting to databases, calling APIs, executing workflows, and making decisions that impact real business operations.

The Model Context Protocol (MCP) powers these connections, and FastMCP has emerged as the leading framework for building MCP servers in Python. Launched just over a year ago, MCP now has 97 million monthly SDK downloads and support from OpenAI, Google, Microsoft, and AWS. As adoption accelerated throughout 2025, DataDome became the first security vendor to introduce comprehensive MCP protection—and today, we’re making it even easier to deploy with our native FastMCP integration.

But here’s the problem this integration solves: every MCP connection is a potential security risk, and most aren’t protected.

MCP servers: The unmonitored attack surface

MCP servers store sensitive credentials, connect to external APIs, and handle high-value business logic. Without protection, they become prime targets for attacks traditional security tools weren’t built to detect: prompt injection, credential abuse, malicious agentic requests, and over-permissioned access.

The threats are real. Researchers found that approximately 7,000 MCP servers were publicly exposed, with hundreds having critical misconfigurations, including remote code execution vulnerabilities.

Why FastMCP & why this integration matters

FastMCP 2.0 is the go-to framework for building MCP servers in Python. It pioneered Python MCP development and was incorporated directly into the official MCP SDK.

Until now, protecting FastMCP servers meant choosing between security and speed.

DataDome is the first vendor to build a native FastMCP integration, enabling protection with minimal implementation effort.

What does this mean for your business?

• Deploy MCP protection in minutes, not days: No architectural rewrites or extended security projects. This integration requires less than 5 lines of code, so your engineering team can deploy protection by the end of the day, not the end of the quarter.
• Real-time MCP Tool visibility: Unlike other tools that only analyze URLs, DataDome captures real-time MCP Tool signals (e.g., BookFlight). This visibility into specific actions allows you to monitor agent behavior and abuse attempts, resulting in more accurate detection and faster investigations than traditional security methods.
• One integration, two ecosystems: Because FastMCP runs on Python’s framework, this also protects FastAPI deployments without any performance penalty.

How the FastMCP integration works

The FastMCP integration automatically detects, classifies, and verifies all traffic to MCP endpoints in real time. By analyzing both the type and intent of each request, it blocks attacks and unauthorized access without disrupting legitimate users or AI agents.

Key benefits of our new integration with FastMCP include:

• Native protection for the #1 MCP framework: DataDome integrates natively with FastMCP, the most adopted MCP framework, blocking malicious AI agent traffic at the application layer before it impacts your services.
• Faster time-to-value to move from integration to production in just a few minutes. It runs behind the scenes with no impact on UX or performance.

DataDome MCP Protection

FastMCP is part of our broader MCP Protection solution, securing agentic connections across your entire infrastructure.

• Intent-based detection catches sophisticated threats like prompt injection and credential abuse that signature-based tools miss.
• Real-time visibility into agentic traffic classifies every request, human, bot, AI agent, or LLM, and gives security teams control over who’s accessing MCP servers.
• Protection on autopilot that blocks malicious threats automatically at the edge before they reach MCP servers.

How to get started with the FastMCP integration 

Our new FastMCP integration is a major addition to an already extensive range of DataDome platform integrations, as we continue to expand our supported infrastructure.
With more than 35 server-side integrations available today, and more than 50 total integrations, DataDome stops malicious AI traffic, bots and online fraud on any infrastructure.
