Protos is a non-custodial, cross-chain crypto copilot — live at tryprotos.xyz, and embeddable anywhere else you work via one API, an Agent Skill, or an MCP server. Type what you want in plain English — prices, smart-money intel, market reads, alerts, token safety, prediction markets, or a swap/bridge/payment — and Protos either pulls live data or hands your wallet a transaction to sign. It never holds your funds or your keys.

​
The core idea

Every execution path in Protos — swaps, bridges, payments, rebalances — returns unsigned calldata. Your own connected wallet signs it. There is no server-side signing, no custodial wallet, no “trust us with your keys.” If Protos disappeared tomorrow, nothing you own would be stuck anywhere. Everything that isn’t execution — prices, risk scans, smart-money reads, market intelligence — is a live data pull. The model is fenced off from inventing numbers: if a live source is unavailable, Protos says so instead of guessing.

​
How to use it

Open the app, connect a wallet, and type into the chat. No forms, no chain pickers, no dropdown menus — just describe the move.

Quickstart

Your first swap, price check, and risk scan in under two minutes.

Connect a wallet

Email, Google, X, Discord, or bring your own wallet.

What Protos can do

The full command surface — swap, bridge, safety, intel, alerts, payments.

Build on Protos

The same copilot over HTTP, as an Agent Skill, or as an MCP server.

​
Three ways to reach it

Protos isn’t only a web app:
  • The app — tryprotos.xyz/app, the full chat UI with cards, charts, and wallet connect.
  • The API — one HTTP endpoint (POST /api/chat) with format:"text" for bots and headless clients. This is what powers Protos’s own iMessage integration today.
  • Agent Skill / MCP — drop a SKILL.md into Claude, Cursor, or any Agent Skills–compatible agent, or run npx -y protos-mcp to get Protos as an MCP server in Claude Desktop, Cursor, or any MCP client.
See Build on Protos for all three.
