Model Context Protocol (MCP) for Enterprises: Secure Integration with AWS, Azure, and Google Cloud — 2025 Update

MCP Overview & Ecosystem

The Model Context Protocol (MCP) is an open standard based on JSON-RPC 2.0 designed to enable AI systems, such as large language models, to securely discover and interact with functions, tools, APIs, or data stores provided by any MCP-compatible server. This protocol addresses the challenges associated with tool integrations, allowing any agent or application that supports MCP to interface with it securely and predictably.

As of 2025, major cloud vendors and AI providers have adopted MCP, leading to a rapidly growing ecosystem. The global MCP server market is projected to reach $10.3 billion by 2025, reflecting increasing enterprise adoption.

AWS: MCP at Cloud Scale

In July 2025, AWS launched several MCP-related services, including:

  • AWS API MCP Server: Allows MCP-compatible AI agents to securely call any AWS API using natural language.
  • Amazon MSK MCP Server: Provides a standardized interface for monitoring Kafka metrics and managing clusters.
  • Price List MCP Server: Offers real-time AWS pricing and availability queries by region.

To integrate AWS MCP services, developers should:

  1. Deploy the desired MCP server using Docker or ECS.
  2. Implement security measures such as TLS and IAM roles.
  3. Define API visibility and capabilities.
  4. Connect with AI clients and monitor performance through CloudWatch.

Microsoft Azure: MCP in Copilot & AI Foundry

Microsoft Azure introduced the Azure AI Foundry MCP Server, which connects various Azure services, allowing developers to streamline integration without custom code. Azure’s Copilot Studio also facilitates the discovery and invocation of MCP capabilities.

Integration steps include:

  1. Building an MCP server in Azure Container Apps or Azure Functions.
  2. Securing endpoints with TLS and Azure AD.
  3. Connecting to backend tools via MCP schemas.

Google Cloud: MCP Toolbox & Vertex AI

Google Cloud’s MCP Toolbox simplifies access to various databases, allowing AI agents to interact with them using minimal code. The Vertex AI platform supports robust multi-agent workflows across tools and data.

Key integration steps involve:

  1. Launching the MCP Toolbox from Cloud Marketplace.
  2. Securing connections with IAM and VPC Service Controls.
  3. Registering MCP tools and exposing APIs for AI consumption.

Cross-Cloud Best Practices

Best practices for implementing MCP across clouds include:

  • Utilizing OAuth 2.0 and TLS for security.
  • Maintaining dynamic MCP capability discovery.
  • Defining well-structured JSON-RPC schemas.
  • Implementing monitoring using tools like OpenTelemetry and CloudWatch.

Security & Risk Management (2025 Threat Landscape)

Enterprises face several security risks, including prompt injection and privilege abuse. To mitigate these risks, it is crucial to only connect to trusted MCP servers and regularly review access privileges.

Expanded Ecosystem: Beyond the “Big Three”

Beyond AWS, Azure, and Google Cloud, other companies adopting MCP include:

  • Netflix: Internal data orchestration.
  • Databricks: Integrating MCP for data pipeline agents.
  • Block (Square), Apollo, FuseBase, Wix: Next-gen enterprise integration.

Example: AWS MSK MCP Integration Flow

To integrate AWS MSK with MCP:

  1. Deploy the AWS MSK MCP server.
  2. Secure the server using Cognito and IAM.
  3. Connect supported AI agents for data invocation.

Summary (July 2025)

The MCP serves as the core open standard for AI-to-tool integrations across major cloud platforms. With robust support and a growing ecosystem, enterprises can leverage MCP for secure and efficient workflows.
