For AI
@tychilabs/tyi-mcp
Agent-native MCP
Stdio MCP server for OpenClaw, Claude Desktop, Cursor, and Codex. Fast onboard, create, and import tools — policy-gated tyi_chat for balance, send, and pay.
npx -y @tychilabs/tyi-mcp@betaThe thesis
Capital is autonomous.
Trust is not.
Agents earn, hold, sign, and pay — often on borrowed keys, with no contract that holds. Tychi gives every agent a wallet it can actually use: self-custody on your machine, policy at the edge, settlement on Arbitrum.
Two interfaces
Built for agents.
Built for humans.
For humans
@tychilabs/tyi
Terminal REPL
Talk to your wallet in plain English. Check balances, send tokens, route gasless payments on Arbitrum — keys stay on your machine.
npx -y @tychilabs/tyi@betaCustody
Keys local.
Brain hosted.
Same model for humans and agents. The host LLM calls tyi_chat — Tychi handles wallet logic and returns text. Signing never leaves your device.

FAQ
Questions.
Tychi is a self-custody agentic wallet — identity, policy, and settlement for autonomous capital. Keys live on your machine. Reasoning runs on Tychi's hosted brain. Signing never leaves your device.
@tychilabs/tyi is the human CLI — an interactive terminal REPL you talk to in plain English. @tychilabs/tyi-mcp is the agent bridge — a stdio MCP server for OpenClaw, Claude Desktop, Cursor, and Codex. Same wallet at ~/.tyi, different interface.
Humans: run npx -y @tychilabs/tyi@beta and complete onboarding. Agents: onboard with tyi first, then wire @tychilabs/tyi-mcp@beta into your MCP host with TYI_PASSWORD in env. Both ship on npm under the @beta tag.
Encrypted keystore at ~/.tyi on your machine. Private keys never reach the hosted brain, your MCP host's LLM, or Tychi servers. The brain handles intent parsing, routing, and policy — signing stays local.
Arbitrum One today — native ETH, ERC-20 tokens, and gasless sends via Universal Gas Framework. Onchain DeFi (automation, trading, lending, borrowing) is coming next on Arbitrum One.
