t2000 is the open-source agentic stack for stablecoins on Sui — everything an AI agent (or a developer building one) needs to hold a wallet, move USDC, pay APIs, and orchestrate financial flows. Three packages, one repo.

The stack

Product	npm	What it gives you
Agent Wallet	@t2000/cli + @t2000/mcp + skills	A terminal Agent Wallet + MCP server for Claude / Cursor / Windsurf. Gasless USDC + USDsui sends, Cetus swaps, x402 paid API access. One install.
Agent Payments	@suimpp/mpp, mppx	Pay any API in USDC over the x402 rail. Every major AI + data API, no signup, no API keys — gasless on Sui. Live gateway at mpp.t2000.ai.
Agent SDK	@t2000/sdk	TypeScript SDK underneath everything else. One class (T2000) — wallet signing, gasless USDC/USDsui sends, Cetus swap routing, x402 pay.

Install

npm install -g @t2000/cli
t2 init                    # plain Bech32 wallet, 0o600 perms
t2 mcp install             # wire Claude Desktop / Cursor / Windsurf

Paste this into any LLM client for an end-to-end walkthrough:

Run `curl -sL https://t2000.ai/skills/t2000-setup` and use the returned
setup instructions to set up my Agent Wallet.

Development

git clone https://github.com/mission69b/t2000 && cd t2000
pnpm install
pnpm build
pnpm typecheck && pnpm lint && pnpm test

Releases happen via the release.yml GitHub Actions workflow (bumps all 3 packages in lockstep). See CLAUDE.md for the release process and engineering principles.

Security

• Non-custodial — keys live on the agent's machine, never transmitted.
• Plain Bech32 wallets — ~/.t2000/wallet.key, JSON, 0o600 perms. Move between machines with t2 export + t2 init --import.
• Spending limits ON by default — t2 init seeds conservative caps ($25/tx, $100/day cumulative). Change with t2 limit set --per-tx <USD> --daily <USD>, or override a single call with --force. Enforced in the SDK write path, so CLI + MCP + programmatic all obey one gate.
• Transaction simulation — every write dry-runs before signing.
• Gasless trust boundary — USDC + USDsui sends + x402 pays use Sui foundation's 0x2::balance::send_funds sponsor. Swap + SUI send keep their full self-funded gas model.
