🤝 Why everyone is talking about a protocol named MCP
Dear curios minds,
This week, I finally understood the Model Context Protocol (MCP) from Anthropic, and I want to share my understanding with you. I never thought I would write about a protocol, but this one is special, and I think it is a game-changer for the AI ecosystem. So let's dive in and learn about it together.

MCP Explained: Why Everyone in AI Is Suddenly Talking About This Protocol
Model Context Protocol (MCP) is rapidly emerging as one of the most significant developments in AI infrastructure, yet many people, including me, are just beginning to understand its transformative potential. As discussed in depth on a recent ThursdAI podcast episode (Media Recommendation below in this issue), MCP represents a fundamental shift in how AI systems communicate with tools, services, and each other.
"This is basically like Zapier for LLM agents" — Jason Kneen on the ThursdAI podcast
A very short but excellent description of the MCP is given by Matt Palmer in the following three-minute-long YouTube video.
Originally open-sourced by Anthropic in November 2024 (announcement), MCP has experienced an explosion in popularity in early 2025. While it initially gained traction among developers, its impact is now becoming evident across the broader AI landscape.
At its core, MCP provides a standardized way for AI agents to interact with external tools and services. Think of it as a universal translator that allows large language models to seamlessly connect with databases, APIs, coding environments, browsers, and virtually any digital tool. This standardization eliminates the fragmented, proprietary approaches that have limited AI capabilities until now.
Examples of what MCP-servers can do:
Browse the web
Read and write access to your calendar
Read and write access to your to-do list
Read and write access to your notes
Rather than employing specific API commands, you (or your agent) simply describe your intention in natural language. The model intelligently selects an appropriate MCP server to fulfill your request when necessary. You can configure that the communication with an MCP server happens automatically or require your explicit confirmation before proceeding.
MCP is an open protocol and works with all models, not just those from Anthropic, creating a truly open ecosystem for AI tool integration. This means your daily chat interactions can now access and even manipulate various data sources that have an MCP server implemented and connected to your chatbot of choice.
The implications are significant. With MCP:
AI assistants can move beyond conversation to take concrete actions in digital environments
Developers can build tool integrations once and have them work with any MCP-compatible model
Users gain access to AI systems that can perform complex, multistep tasks across various applications
Currently, most MCP servers run locally on your machine through “stdio” (requiring tools like npx or uvx), but the ecosystem is evolving toward remote operation via Server-Sent Events (SSE).
As with any major technological shift, MCP raises important questions about safety, privacy, and control. When AI systems can freely access and manipulate a wide range of tools, how do we establish appropriate boundaries? Who determines what actions an AI agent can take on behalf of users? These questions become increasingly urgent as MCP adoption accelerates.
As we move toward a world populated by AI agents that can perform increasingly complex tasks on our behalf, the need for standardized ways for these agents to discover capabilities and communicate becomes crucial. MCP appears to become the foundation upon which the next generation of AI applications will be built.
For anyone working with AI systems, whether as a developer, business leader, or enthusiast, understanding MCP and its implications will be increasingly important. The protocol has the potential to reshape how we all interact with AI in our daily lives.
📰 AI Update
Local AI Revolution: QwQ-32B Brings DeepSeek-Level Reasoning To Your Own Hardware [Qwen blog]
The preview version of QwQ-32B was already achieving great results. But it is remarkable that the final version of QwQ-32B from Alibaba's Qwen team achieves performance comparable to DeepSeek R1 with just 32 billion parameters compared to DeepSeek's massive 671 billion parameters (with 37 billion active per token). The practical implication is significant: while DeepSeek R1 requires cloud infrastructure, QwQ-32B can be run locally on consumer hardware, democratizing access to high-quality AI reasoning capabilities.
Mistral OCR: Turning Difficult Documents into Actionable Data [Mistral blog]
Mistral OCR delivers industry-leading accuracy that surpasses competitors in processing even the most challenging documents, including poorly scanned PDFs, complex mathematical expressions and content in thousands of languages. The ability to process up to 2000 pages per minute at a competitive price of 1000 pages per dollar is outstanding.

Podcast: ThursdAI Unpacks the True Potential of MCP
The ThursdAI podcast hosted by Alex Volkov has become an essential weekly resource for staying updated on the most significant AI developments.
This week's episode included discussions with Alibaba's Qwen team about their impressive QwQ-32B model and Google's VP of Search Product about their new AI Mode.
The highlight of the episode is an extensive segment on the Model Context Protocol (MCP), which explains why this emerging standard is currently generating so much excitement in the AI community.
If you're wondering what all the MCP hype is about, I highly recommend listening to at least this portion of the episode (starts at the 48:16 minute mark). It provides a clear explanation of how this technology works and why it represents such a significant advancement for AI tools.
My take: After listening to the podcast episode, I finally understand why MCP is creating such a buzz. The possibilities are nearly endless - imagine your AI assistant being able to seamlessly access your GitHub repositories, manage your Stripe payments, or control your smart home devices, all through a standardized protocol.
