Overview

AI-generated overview

Remote MCP endpoint that gives an assistant semantic search over Sui documentation and knowledge sources, powered by kapa.ai.

What you can do
  • Search Sui documentation and knowledge sources semantically
  • Retrieve relevant passages about the Sui blockchain, its architecture, the Move language and the SUI token
  • Answer questions about the Sui ecosystem from indexed sources
When to use it
Useful when you work with Sui or Move and want an assistant to look up documentation and ecosystem facts instead of relying on memory. Suited to developers and researchers asking conceptual or reference questions about the Sui platform.
Requirements
A remote MCP client connecting to the hosted endpoint; OAuth authentication is required. No local package, environment variables or headers are declared.
Before you install
Access requires an OAuth sign-in, so the provider sees the account identity used. Queries are sent to a third-party hosted service (kapa.ai) rather than answered locally.

Installation

In SourceWeft

  1. Open Sui Knowledge Base (kapa.ai) in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.MystenLabs%2Fsui-kapa/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Welcome to Sui

[Github release] [License]

Sui is a next-generation smart contract platform with high throughput, low latency, and an asset-oriented programming model powered by the Move programming language.

Sui Highlights

Sui offers the following benefits and capabilities:

  • Unmatched scalability, instant settlement
  • A safe smart contract language accessible to mainstream developers
  • Ability to define rich and composable on-chain assets
  • Better user experience for web3 apps

Sui is the only blockchain today that can scale with the growth of web3 while achieving industry-leading performance, cost, programmability, and usability. Sui demonstrates capacity beyond the transaction processing capabilities of established systems – traditional and blockchain alike. Sui is the first internet-scale programmable blockchain platform, a foundational layer for web3.

Sui Overview

Sui is a smart contract platform maintained by a permissionless set of authorities that play a role similar to validators or miners in other blockchain systems.

Sui offers scalability and unprecedented low-latency for common use cases. Sui makes the vast majority of transactions processable in parallel, which makes better use of processing resources, and offers the option to increase throughput with more resources. Sui forgoes consensus to instead use simpler and lower-latency primitives for common use cases, such as payment transactions and asset transfers. This is unprecedented in the blockchain world and enables a number of new latency-sensitive distributed applications, ranging from gaming to retail payment at physical points of sale.

Sui is written in Rust and supports smart contracts written in the Move programming language to define assets that may have an owner. Move programs define operations on these assets including custom rules for their creation, the transfer of these assets to new owners, and operations that mutate assets.

Sui has a native token called SUI, with a fixed supply. The SUI token is used to pay for gas, and is also used as delegated stake on authorities within an epoch. The voting power of authorities within this epoch is a function of this delegated stake. Authorities are periodically reconfigured according to the stake delegated to them. In any epoch, the set of authorities is Byzantine fault tolerant. At the end of the epoch, fees collected through all transactions processed are distributed to authorities according to their contribution to the operation of the system. Authorities can in turn share some of the fees as rewards to users that delegated stakes to them.

Sui is supported by several cutting-edge peer-reviewed studies and extensive years of open-source development.
