Sui Knowledge Base
MCP server by MystenLabs
Search Sui documentation and knowledge sources with semantic search powered by kapa.ai
Connect to Sui Knowledge Base
Sui Knowledge Base needs sign-in. Connect with its own URL:
Your client opens MystenLabs’s sign-in the first time you use it. The token stays between your client and MystenLabs.

mcp.tc/i/sui-knowledge-baseAbout
Connects an assistant to the Sui knowledge base, which covers Sui documentation and related knowledge sources. It runs semantic search so answers about Sui, the Move language and the Sui ecosystem can come from the source material instead of model memory.
It runs as a hosted streamable HTTP endpoint at https://sui.mcp.kapa.ai. The endpoint accepts OAuth tokens, but the vendor does not document how users get access, so sign-in details are not confirmed.
What you can do
- Search Sui documentation semantically
- Look up answers from Sui knowledge sources
- Ground Move and Sui development questions in official material
Tools
Sui Knowledge Base lists its tools only after you sign in, so we can’t show them here. Your client lists them once you’re connected.
Example prompts
How do I define an object with a key ability in Sui Move?
Search the Sui docs for how gas fees are calculated.
What does the Sui documentation say about staking SUI?
Set up
Every client connects to sui.mcp.kapa.ai, and MystenLabs asks you to sign in the first time. Pick yours; the page remembers your choice.
Claude Code
- Run this in a terminal, in your project folder:
claude mcp add --transport http sui-knowledge-base https://sui.mcp.kapa.ai- Start Claude Code, type
/mcp, pick sui-knowledge-base and choose Authenticate. A browser window opens for the MystenLabs sign-in.
Add --scope user to make it available in every project, not just this one.
Claude Desktop
- Open Customize → Connectors, click + Add, then Add custom connector.
- Name it Sui Knowledge Base and paste this URL:
https://sui.mcp.kapa.ai- Click Add, then Connect, and sign in when MystenLabs asks.
Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.
claude.ai
- Open the connector form on claude.ai. This button fills in the name and URL for you:
Add to claude.ai (opens in a new tab)
- Check that the URL reads
https://sui.mcp.kapa.aiand click Add. - Click Connect and sign in when MystenLabs asks.
Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under Organization settings → Connectors.
ChatGPT
- On chatgpt.com, go to Plugins, select +, then Add custom MCP server.
- Enter a name for the server.
- Under Connection, paste
https://sui.mcp.kapa.aias the server URL, then for authentication choose OAuth. ChatGPT sends you to MystenLabs to sign in. - Check I understand and want to continue, then select Create as a plugin.
Whether you can add a custom MCP server depends on your ChatGPT plan and your workspace permissions (in Business workspaces, admins and owners can).
Cursor
Add to Cursor (opens in a new tab)
Or add it by hand to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project):
{
"mcpServers": {
"sui-knowledge-base": {
"url": "https://sui.mcp.kapa.ai"
}
}
}Cursor shows Needs authentication next to the server. Click the button beside it to sign in.
VS Code
Install in VS Code (opens in a new tab)
Or from a terminal:
code --add-mcp '{"name":"sui-knowledge-base","type":"http","url":"https://sui.mcp.kapa.ai"}'Or commit it to the repo in .vscode/mcp.json:
{
"servers": {
"sui-knowledge-base": {
"type": "http",
"url": "https://sui.mcp.kapa.ai"
}
}
}VS Code asks you to sign in the first time the server starts.
Devin Desktop
- Add it to
~/.config/devin/mcp_config.json(macOS and Linux) or%APPDATA%\devin\mcp_config.json(Windows):
{
"mcpServers": {
"sui-knowledge-base": {
"serverUrl": "https://sui.mcp.kapa.ai"
}
}
}- Refresh the MCP server list in Cascade and sign in when asked.
Devin Desktop is the new name for Windsurf. It reads serverUrl (or url) for remote servers.
Codex
codex mcp add sui-knowledge-base --url https://sui.mcp.kapa.ai
codex mcp login sui-knowledge-baseOr edit ~/.codex/config.toml directly:
[mcp_servers.sui-knowledge-base]
url = "https://sui.mcp.kapa.ai"Gemini CLI
gemini mcp add --transport http sui-knowledge-base https://sui.mcp.kapa.aiThen, inside Gemini CLI, run /mcp auth sui-knowledge-base to sign in.
This adds it to the current project. Add -s user to use it everywhere.
Any client
Most clients accept this shape. Some name the URL field differently: serverUrl in Devin Desktop, httpUrl in Gemini CLI’s settings file.
{
"mcpServers": {
"sui-knowledge-base": {
"type": "http",
"url": "https://sui.mcp.kapa.ai"
}
}
}Zed puts servers under context_servers in its settings. Cline needs "type": "streamableHttp", or it assumes SSE.
Client only starts local servers? Bridge it with npx -y mcp-remote https://sui.mcp.kapa.ai.
Embed
Show Sui Knowledge Base in a README or on your site. Each embed links to this page, uses the server’s own URL, and sets no cookies. How embeds work
The card, the iframe and the JSON are in English. Add ?lang=it, fr, de or es to their address for another language.
README badge
[](https://mcp.tc/i/sui-knowledge-base)<a href="https://mcp.tc/i/sui-knowledge-base"><img src="https://mcp.tc/i/sui-knowledge-base/badge.svg" alt="Sui Knowledge Base on mcp.tc" height="20"></a>It follows the reader’s light or dark mode. Add ?theme=light or ?theme=dark to fix it, or ?style=compact to show the mark without the word.
Website card
<script src="https://mcp.tc/w/sui-knowledge-base.js" async></script>The card appears where the tag is. Add data-theme="dark" or data-size="compact" to the tag to change it. The file holds everything it needs, so it makes no other requests and sets no cookies.
iframe
<iframe src="https://mcp.tc/embed/sui-knowledge-base" title="Sui Knowledge Base on mcp.tc" width="420" height="200" loading="lazy" allow="clipboard-write" style="border:0;border-radius:8px;max-width:100%"></iframe>Use it on pages that don’t allow scripts. Add ?theme=light or ?theme=dark to the address to fix the colors.
JSON
The listing as data for your own pages and tools: name, tagline, the server’s own URL, tools and the “Add to” links. Any site can read it (CORS is open).
https://mcp.tc/i/sui-knowledge-base.jsonAI prompt
Paste this into an AI coding assistant, such as Claude Code or Cursor, and it adds the Sui Knowledge Base card to your site.
Add the mcp.tc card for Sui Knowledge Base, an MCP server, to my website. It is one static script: no build step, no package to install, no cookies.
Put this tag where the card should appear. The card renders right before it:
```html
<script src="https://mcp.tc/w/sui-knowledge-base.js" async></script>
```
To show the card somewhere else, put this placeholder there and load the same script once, for example before `</body>`. Keep the link inside: visitors without JavaScript see it.
```html
<div data-mcptc="sui-knowledge-base"><a href="https://mcp.tc/i/sui-knowledge-base">Sui Knowledge Base on mcp.tc</a></div>
```
Options:
- `data-theme="light"` or `"dark"` on the tag or the placeholder fixes the colors. Without it, the card follows the visitor’s light or dark mode.
- `data-size="compact"` gives a smaller card without the tagline.
- The CSS variable `--mcptc-max-width` on the placeholder or a parent sets the width (default `520px`).
- `?lang=` on the script URL sets the card’s language: `en`, `it`, `fr`, `de` or `es`.
If the site has a Content Security Policy, allow `script-src https://mcp.tc` and `img-src data:` (the icon is inline).
For a README or other Markdown docs, use the badge instead:
```markdown
[](https://mcp.tc/i/sui-knowledge-base)
```

FAQ
Can I paste mcp.tc/i/sui-knowledge-base into my MCP client?
No. mcp.tc links are pages, not server addresses. Connect with https://sui.mcp.kapa.ai, so your client talks to Sui Knowledge Base directly. The sign-in token only works there anyway. The quick link is for sharing: it opens this page, with setup steps for every client.
Does Sui Knowledge Base need an API key or a sign-in?
Yes, you need a MystenLabs account. The first time your client connects, it opens MystenLabs’s sign-in page. The token goes straight to the server’s own URL, never through mcp.tc.
Is Sui Knowledge Base a remote or a local server?
Remote. MystenLabs hosts it at https://sui.mcp.kapa.ai, and it speaks Streamable HTTP. There’s nothing to install.
What can Sui Knowledge Base do?
You can search Sui documentation semantically, look up answers from Sui knowledge sources and ground Move and Sui development questions in official material.
Which clients can use it?
Any client that supports remote MCP servers: Claude Code, Claude Desktop, claude.ai, ChatGPT, Cursor, VS Code, Devin Desktop, Codex, Gemini CLI, Zed and others. The setup steps cover each one.
Does mcp.tc track changes to Sui Knowledge Base?
Partly. Sui Knowledge Base’s tools are behind a sign-in, so its History tab shows only edits by its owner. Follow the listing to get an email when it changes.
Who wrote this page?
mcp.tc’s robot read Sui Knowledge Base’s own metadata (its MCP handshake, tool list and public pages), and an AI model drafted the text from it. A person reviews anything the checks can’t confirm. The text can still be wrong, so if you spot a mistake, use Report this listing on this page.
mcp.tc isn’t affiliated with MystenLabs. This page was built from Sui Knowledge Base’s public metadata, last checked on 15 Nov 2026, and an AI model wrote the description, so it can be wrong. Names and marks belong to their owners. Something off? Report this listing.
