Sui Knowledge Base (kapa.ai) — Claude Code MCP server for Sui docs
Semantic search over Sui documentation and related knowledge sources, powered by kapa.ai. Useful when your agent writes Sui code and needs answers straight from the docs.
claude mcp add --transport http sui-kapa https://sui.mcp.kapa.aiWhat Sui Knowledge Base (kapa.ai) does
The server connects to the remote endpoint https://sui.mcp.kapa.ai and answers questions about Sui documentation. Search is semantic, so it matches meaning rather than exact words. Ask it how to define an owned object and it returns the relevant docs section instead of a file list.
It runs over HTTP, so there is nothing to host locally. No API key or token is needed either. Setup is one command per platform: in Claude run claude mcp add --transport http sui-kapa https://sui.mcp.kapa.ai, in Codex run codex mcp add sui-knowledge-base-kapaai --url https://sui.mcp.kapa.ai. Cursor, GitHub Copilot and Gemini CLI take a config snippet or their own add command.
The scope is narrow: Sui and Move only. On an unrelated stack it gives you nothing. For Sui contract work that narrowness is the point, because models tend to mix up API versions and pull in outdated examples.
What it helps with
- find a current example of working with Sui objects
- check Move syntax before writing a contract
- understand Sui architecture without reading the whole docs site
- verify how transactions and gas work in Sui
- get a link to the right docs section from a plain description
Example prompts for the agent
- Find how to create an owned object in Sui and show a Move example
- How does gas payment work in Sui? Link me to the docs section
- Check my Move contract against the current Sui documentation
