In the rapidly evolving landscape of artificial intelligence, the concept of the "agentic web" is emerging as a transformative paradigm. This vision, championed by industry leaders like Microsoft CTO Kevin Scott, envisions AI agents that not only respond to queries but autonomously navigate across platforms, access diverse tools, and execute complex tasks. Central to realizing this vision is the adoption of open standards, a lesson drawn from the early days of the internet and the so-called "browser wars."

Lessons from the Browser Wars​

The 1990s witnessed a fierce competition among web browsers, notably between Microsoft's Internet Explorer and Netscape Navigator. Microsoft's integration of Internet Explorer into its Windows operating system led to antitrust scrutiny, with critics accusing the company of attempting to monopolize the web through proprietary protocols and anti-competitive practices. This period underscored the perils of closed, vertically integrated approaches that can stifle innovation and limit user choice.
Reflecting on this history, Kevin Scott emphasizes the importance of openness and simplicity in the development of AI agents. He warns that a closed ecosystem could hinder the full potential of AI, advocating for standards that allow AI agents to "talk to everything in the world." This perspective aligns with the broader industry consensus that interoperability and open standards are crucial for fostering innovation and collaboration.

The Emergence of Open Protocols​

To facilitate seamless interaction among AI agents, several open protocols have been introduced:

Model Context Protocol (MCP)​

Developed and open-sourced by Anthropic, MCP defines how AI models access and interact with external tools and data sources. It provides a standardized framework that enables AI agents to securely connect with a vast ecosystem of tools, APIs, and internal resources. Microsoft has expressed strong support for MCP, citing its simplicity and flexibility, which allow developers to build upon it over time without overhauling existing systems. (microsoft.com)

Agent2Agent Protocol (A2A)​

Introduced by Google, the A2A protocol is designed to enable AI agents to communicate and collaborate directly across different systems and platforms. It acts as a universal language for AI agents, allowing them to advertise capabilities, negotiate tasks, and exchange data securely. Microsoft has embraced A2A, integrating support for the protocol into its Azure AI Foundry and Copilot Studio platforms. This integration signifies a commitment to fostering interoperability and reducing vendor lock-in. (microsoft.com)

NLWeb Protocol​

In addition to MCP and A2A, Microsoft has introduced NLWeb, an open-source protocol aimed at making websites and APIs more accessible to AI agents. NLWeb is designed to work with large language models, transforming web content into formats that AI agents can navigate and utilize through natural language. This initiative reflects Microsoft's broader strategy to enhance the agentic web by ensuring that AI agents can interact with a wide array of digital resources.

Microsoft's Strategic Shift​

Microsoft's adoption of open protocols like MCP and A2A marks a significant shift from its historical approach during the browser wars. By supporting these standards, Microsoft aims to create a more collaborative and interoperable AI ecosystem. This strategy is evident in several key initiatives:
  • Integration into Core Platforms: Microsoft has integrated support for MCP and A2A into platforms like Azure AI Foundry and Copilot Studio, enabling developers to build complex, multi-agent workflows that span internal and external tools while maintaining governance and service-level agreements. (microsoft.com)
  • Enterprise-Grade Security: The company emphasizes secure and observable agent communication, incorporating enterprise safeguards such as Microsoft Entra, mutual TLS, Azure AI Content Safety, and comprehensive audit logging. This focus on security ensures that AI agents can collaborate across platforms without compromising data integrity. (microsoft.com)
  • Community Collaboration: Microsoft has joined the A2A working group on GitHub, contributing to the protocol's specification and tooling. This collaborative approach underscores the company's commitment to open standards and collective innovation. (microsoft.com)

Implications for the AI Ecosystem​

The adoption of open standards like MCP and A2A has profound implications for the AI ecosystem:
  • Enhanced Interoperability: Open protocols enable AI agents from different vendors and platforms to communicate and collaborate seamlessly, reducing fragmentation and fostering a more cohesive AI landscape.
  • Accelerated Innovation: By removing barriers to integration, open standards encourage experimentation and the development of new applications, driving rapid advancements in AI capabilities.
  • Improved Security and Compliance: Standardized protocols facilitate secure data exchange and simplify compliance auditing, ensuring that AI agents operate within established regulatory frameworks.

Challenges and Considerations​

While the move towards open standards is promising, several challenges remain:
  • Standardization Efforts: Achieving consensus on protocol specifications requires collaboration among diverse stakeholders, which can be a complex and time-consuming process.
  • Implementation Complexity: Integrating new protocols into existing systems may require significant technical effort, particularly for organizations with legacy infrastructure.
  • Security Concerns: Ensuring that open protocols are secure against potential threats is paramount, necessitating ongoing vigilance and updates to address emerging vulnerabilities.

Conclusion​

The lessons from the browser wars highlight the importance of openness and interoperability in technological development. By embracing open standards like MCP and A2A, Microsoft and other industry leaders are paving the way for an agentic web where AI agents can collaborate across platforms and systems. This approach not only fosters innovation but also ensures that the AI ecosystem remains dynamic, secure, and inclusive.
As the AI landscape continues to evolve, the commitment to open standards will be crucial in realizing the full potential of autonomous agents and the agentic web.

In a world racing toward widespread artificial intelligence adoption, Microsoft’s latest vision for the “agentic web” represents a pivotal moment that harks back to the foundational days of the modern internet. Rather than embracing siloed systems and proprietary ecosystems, the company’s Chief Technology Officer, Kevin Scott, is championing a new landscape where AI agents — software entities that perform tasks, learn, and interact — can seamlessly collaborate across organizational boundaries. This bold initiative aims to build a collaborative, memory-enabled network of AI agents woven together by open standards, mirroring the exponential innovation unleashed by the birth of the internet’s open protocols.

The Road to the Agentic Web: Lessons From Internet’s Early Days​

Scott’s vision, articulated ahead of Microsoft’s Build developer conference and reported by GeekWire and WebProNews, draws a direct parallel between the emergent agentic web and the formative years of the World Wide Web. In the 1990s, open standards like HTML and HTTP democratized access to information and fueled a diverse ecosystem of browsers, services, and innovations. The core principle was simple yet revolutionary: by agreeing on protocols, anyone could build atop a shared platform — allowing imagination, not exclusivity, to set the pace of progress.
Translating this ethos to AI, Scott argues that the next wave of artificial intelligence development must refuse proprietary lock-in and instead embrace standards that ensure interoperability. The goal, according to Scott, is not to have a handful of tech giants dictate the fabric of the new AI economy, but rather to create an environment where collaboration breeds innovation, competition, and resilience. “Your imagination gets to drive what the agentic web becomes, not just a handful of companies that happen to see some of these problems first,” Scott told reporters.

Breaking the Walls: Current Limitations of AI Silos​

Today, AI agents — regardless of their impressive capabilities — remain constrained by several key limitations. Chief among them is the absence of persistent, context-aware memory. Most AI systems today operate transactionally: each interaction is effectively isolated from past experiences. An agent asked to book a flight tomorrow will have no recollection that, moments earlier, the user asked for a hotel reservation in the same city. This fundamental shortcoming stems from:
  • Lack of persistent memory: AI systems do not retain user history over time.
  • Limited interoperability: AI agents from different vendors or platforms cannot share knowledge or operate in tandem.
  • Transactional design: Current models must reprocess data from scratch each session, mirroring an individual who wakes up with no memory each day.
These flaws are more than inconvenient — they are fundamentally limiting. In Scott's analogy, the brain does not “brute force everything in your head every time you need to solve a particular problem.” Instead, it learns, builds upon past knowledge, and adapts. For AI agents to truly rival the versatility and productivity of human collaborators, they need to do the same.

The Model Context Protocol (MCP): Pioneering a Common Language​

Microsoft’s proposal to remedy these constraints shines a spotlight on the Model Context Protocol (MCP), an open standard initiated by AI startup Anthropic and now championed by Microsoft and Google. MCP’s goal is to serve as a universal “language” that allows AI agents — regardless of their underlying architecture or provider — to exchange context, intentions, memory snippets, and operational data.
This effort directly mirrors how HTML allowed diverse browsers and servers to “speak” to one another, unleashing what Kevin Scott describes as a “Cambrian explosion of innovation.” With MCP, the agentic web would allow:
  • AI agents to remember interactions and share this context with other agents
  • Businesses to connect their proprietary AI solutions with partners and vendors securely
  • Developers to innovate faster without being locked into a specific vendor’s ecosystem
Industry observers widely recognize that for this standard to gain traction, it will require broad buy-in. Microsoft is well aware that the MCP’s real value will only be realized if adopted by a large swath of the industry, much like how early internet standards only succeeded because of their cross-company uptake.

The Challenge of AI Memory: Structured Retrieval Augmentation​

While interoperability is one half of the equation, persistent memory is the other. Equipping AI agents with memory is not a trivial technical challenge. Storing, retrieving, and leveraging vast troves of contextual information demands enormous computational resources — and, with current technology, incurs significant costs. As Scott remarks, memory efficiency is both a technical and economic imperative: “We want to make it so that any company’s AI agents can work together with those from other companies and have a memory that persists.”
To tackle this, Microsoft is pursuing techniques such as structured retrieval augmentation. This approach allows AI agents to extract, summarize, and retain only the most relevant information from each conversational turn, piecing together an internal map of a user or task over time.
This model, which mimics human cognitive strategies, promises significant practical benefits:
  • Complex task handling: Agents can manage projects or workflows spanning multiple steps and over extended periods, rather than resetting context on each new command.
  • Personalization: AI can recall user preferences, historical data, or nuanced requirements to deliver tailored interactions.
  • Knowledge transfer: Insights, strategies, or best practices learned in one context could be transferred to other agents or settings — much as organizational memory does in human enterprises.
However, challenges remain. Memory architectures must balance comprehensiveness with privacy. They must be efficient enough to scale, yet robust enough to enable meaningful collaboration. This is not just an engineering hurdle; it is a foundational leap akin to the transition from static websites to dynamic, interactive, and personalized web applications.

A Critical Industry Juncture: Microsoft’s Strategic Bet​

The push for an agentic web comes at a critical moment. Across industries, enterprises are waking to the realization that AI’s true power is unlocked only when systems can operate cohesively at scale, not as isolated point solutions. Interoperability and memory have rapidly become boardroom priorities. As The Economic Times and other reporting has noted, companies are scouting for AI infrastructure that can adapt, scale, and integrate into the increasingly complex matrices of modern business.
Microsoft’s approach is reminiscent of its support for interoperability in the age of Windows and Office, and more recently its participation in open-source foundations. The company appears to be positioning itself as a convener, much as the World Wide Web Consortium (W3C) did for internet standards. By embracing and advocating open protocols, Microsoft is signaling a willingness to help define, rather than dominate, the next era of digital transformation.

Under the Hood: How Structured Retrieval Augmentation Works​

The specifics of structured retrieval augmentation involve several key techniques:
  • Turn-level data extraction: After each user or system input, the AI agent evaluates the relevance of new information and records critical details only.
  • Hierarchical memory storage: Rather than storing raw conversation logs, the agent constructs summaries and mappings, similar to the brain’s approach to key concepts and memories.
  • Context linking: When an agent is invoked for a recurring or related task, it draws upon the collected summaries, effectively connecting the present to the past.
Microsoft’s research has found that this approach yields significant improvements, especially in multi-turn, complex workflows (as reported by research partners and technical whitepapers). Nonetheless, the cost-savings curve flattens as the number of active memories climbs, underscoring the need for continuous optimization and innovation.

The Economic Stakes: Open Standards versus Proprietary Lock-In​

Scott’s advocacy for an open, collaborative agentic web strikes at the core of contemporary tech debates. The first real browser war was about who would shape internet access — the victor could set the rules for participation, innovation, and monetization for decades. Today, the stakes are even higher, with AI poised to underpin everything from digital assistants and autonomous logistics to healthcare diagnostics and creative tools.
Open standards have historically proven advantageous in driving innovation. Examples abound:
  • Internet protocols: Open standards allowed Google, Facebook, and thousands of other companies to build on shared infrastructure.
  • USB: Universal standards made it possible for any hardware manufacturer to develop peripherals, turbocharging the PC revolution.
  • Cloud APIs: Efforts to standardize inter-cloud communication have led to a more vibrant, competitive cloud ecosystem.
By contrast, closed, proprietary ecosystems may offer short-term technical advantages, but they tend to stifle competition, slow the rate of improvement, and lock customers into vendor-specific solutions. Scott’s framing of the agentic web as “imagination-driven” serves as a rallying cry for developers, researchers, and enterprises eager to avoid another round of platform enclosures.

Critical Analysis: Balancing Promises with Pitfalls​

Despite the promise and intent behind Microsoft’s agentic web manifesto, several risks and challenges must be highlighted for a complete perspective:

Strengths​

  • Interoperability unlocks innovation: History repeatedly demonstrates that open standards enable unanticipated use cases and entrepreneurial growth.
  • Customer centricity: By enabling persistent memory and personalization, end users and businesses stand to benefit from more capable, intuitive agents.
  • Ecosystem resilience: Multiple companies collaborating on standards creates a more robust, secure, and future-proof ecosystem.
  • Developer empowerment: A universal platform enables a broader developer community to experiment, build, and disrupt.

Weaknesses and Risks​

  • Coordination dilemma: Convincing market competitors to collaboratively define and implement standards is notoriously challenging. If progress stalls, proprietary solutions may fill the void, fragmenting the landscape.
  • Security and privacy: Persistent AI memory raises substantial questions about data sovereignty, privacy rights, and regulatory compliance. Mishandling could undermine user trust and expose organizations to legal risk.
  • Cost and scalability: Memory augmentation may drive up infrastructure expenses — at least initially — potentially limiting accessibility to AI-native workflows for less-resourced organizations.
  • Risk of lowest-common-denominator standards: In some cases, the need to secure buy-in from multiple parties leads to standards that are too limited for the most advanced use cases.

Cautionary Perspective​

It is worth noting, as with any industry-driven initiative, that the boldest visions may not always materialize if economic or technical headwinds prove overwhelming. While Microsoft and other technology leaders express optimism, the timeline for broad adoption of the agentic web and MCP remains dependent on industry consensus, developer engagement, and evolving commercial imperatives.

The Developer’s Perspective: What to Expect at Microsoft’s Build Conference​

This year’s Build conference is set to be a proving ground for these concepts. Developers can expect new tools and APIs aimed at simplifying multi-agent interactions, memory management, and cross-company integrations. Early indications suggest that Microsoft will unveil enhancements to Azure’s AI offerings as well as open-source contributions to MCP and related interoperability projects.
For developers and IT professionals, this represents both an opportunity and a challenge. The skills required to design, deploy, and secure collaborative AI agents will be in high demand — and early adopters may find themselves at the forefront of the next digital revolution.

Key Areas of Anticipation​

  • Toolkit releases: New SDKs and libraries to enable agentic interoperability.
  • Security frameworks: Blueprints for data protection, access control, and compliance.
  • Best practices: Documentation and case studies from early adopters, demonstrating real-world benefits and pitfalls.

The Bigger Picture: Implications for the AI-Powered Economy​

The potential impact of the agentic web reaches far beyond technical implementation. If successful, this movement could reshape digital business, public services, and personal productivity at a fundamental level. Imagine a healthcare environment where diagnostic agents, scheduling bots, and insurance verifiers all collaborate to deliver holistic care. Picture global supply chains where autonomous purchasing, logistics, and compliance agents interact seamlessly.
Such scenarios rely on trust, security, and permissioned transparency — all of which will demand both technical and policy innovation. The agentic web can only thrive if privacy safeguards and user consent mechanisms evolve in parallel with memory and context-sharing breakthroughs. Regulatory frameworks will no doubt be tested and stretched by the realities of persistent, cross-company AI memory.

Conclusion: A Tipping Point for Artificial Intelligence Interoperability​

Microsoft’s campaign for the agentic web is as much a call to arms for open innovation as it is a technical roadmap. By channeling the collaborative spirit that defined the origin of the web itself, Microsoft, Anthropic, Google, and other participants are betting that shared standards will outpace proprietary silos in realizing AI’s true transformative potential.
As the industry stands on the cusp of this next chapter, the lessons of the past are unmistakably relevant: open, interoperable platforms win — not merely for any one company, but for developers, businesses, and users worldwide. The agentic web, if realized, could anchor the next era of digital transformation, driving advances that are as yet unimagined. The challenge now is for the industry to coordinate, commit, and collectively author the standards on which the next economy will be built. Only then will the dream of seamless AI collaboration become reality, ushering in an age where intelligent agents work not just for us, but with each other — and, ultimately, for the greater good.
