- Sei Network integrates Anthropic’s Model Context Protocol to enable secure on-chain interaction through Claude, Windsurf, and Cursor.
- AI agents can now read blockchain data and execute transactions directly using standard interfaces on Sei Network.
Sei Network has integrated the Model Context Protocol (MCP) into its network. MCP is not just a new feature, but a super-fast way to connect AI systems like Claude, Cursor, and Windsurf directly to on-chain data and transactions on the Sei Network. No more complicated connectors or custom integrations—AI can pull wallet data, read smart contracts, and even execute DeFi transactions using just one open standard.
What makes this move even more interesting is that the MCP protocol was developed by Anthropic and was once touted as the “USB-C” of the AI world. This means that one cable—or in this case, one protocol—can connect to many things.
AI can now understand what’s happening on the Sei blockchain without having to guess what’s going on behind the scenes. Just send a request, and the data comes out. Or even more excitingly, AI can take action right away. Send tokens? Yes. Join a farm? Yes. Find out who has the most SEI in a liquidity pool? Also possible.
Model Context Protocol is now live on Sei.

Sei’s Giga Upgrade Pushes Blockchain Speed to New Heights
Of course, for all of this to run smoothly, the network itself must be fast. And Sei, it’s fair to say, is ready. Last April, they introduced a major upgrade called the Giga Upgrade. Just imagine, the processing speed reaches 5 gigagas per second on their internal developer network spread globally.
For non-engineers, this is roughly like a blockchain engine that can handle hundreds of thousands of complex transactions, without any hassle.
The technology behind this perform is called Autobahn, a consensus protocol that combines asynchronous data propagation with the BFT consensus mechanism.
As proof, in early July, CNF recorded that Sei managed to process 4.6 million transactions in one day—beating Sui, which had previously dominated the daily metric. At almost the same time, the total value locked (TVL) across all of Sei’s DeFi protocols also broke through the $600 million mark for the first time.
As Sei Network Grows, So Does Its Focus on User Safety
But amid the surge in activity, the question arises: what about security? Interestingly, Sei did not let their network grow without supervision. Last week, as we highlighted, MyWebAcy—an on-chain risk rating platform—officially joined Sei.
Its purpose? To provide a real-time risk assessment system that all users can access. So if a suspicious address or strange transaction comes under the radar, users can get an early warning before it’s too late.
This rapidly growing environment also supports the emergence of such security applications. DEX volumes are increasing, AI integrations are becoming more complex, and users are growing. Without extra oversight, things can get messy. So having a tool like MyWebAcy is not just important—it’s necessary.
On the other hand, with MCP now live, new possibilities are emerging: AI bots that can filter out scams, make automated decisions about staking or trading, and even verify the validity of smart contracts in seconds. What used to require a team of analysts, now might be enough with just one smart prompt.
However, it’s not all without its risks. Several researchers have raised potential loopholes in open standards like MCP—from data manipulation, prompt injection, to “tool poisoning” scenarios. But that’s no reason to back down. This is precisely where innovation is tested: can it grow without sacrificing integrity?
Sei seems to want to answer that challenge. The launch of MCP is just one part of the big picture. They are not only aiming for the title of “fastest blockchain” but also the most AI-friendly ecosystem.
Meanwhile, as of press time, their native token, SEI, is trading at about $0.2601, slightly down 0.77% over the last 24 hours but still in a rally of about 33.66% over the last 30 days.
