About Tychi MCP Server

Give your AI agent a wallet it can actually use. Tychi MCP plugs into Cursor, Claude Desktop, OpenClaw, and any stdio MCP host — onboard, create, import, and switch wallets with fast direct tools, then balance checks, sends, and policy-gated payments through tyi_chat. Keys live e

Tychi MCP Server tools

9

READ FIRST. Intent → tool map. Call before any wallet op. Prevents slow tyi_chat misuse.

Check ready + missing. Call once at session start.

Onboarding field schema. Use with tyi_onboard — not tyi_chat.

FAST. First-time setup only. NOT tyi_chat.

FAST. New wallet by name. User said create/new wallet → call this NOT tyi_chat.

FAST. Import seed/privkey. User said import/restore → call this NOT tyi_chat. Secret via tool param only.

FAST. Set active wallet by name. NOT tyi_chat.

Wipe ~/.tyi. confirm:true required. NOT tyi_chat.

SLOW brain agent. ONLY: balance, send, pay, transfer, policy, limits, history, general Q. NEVER: create wallet, import, onboard, reset, switch — use dedicated tyi_* tools instead.

Overview

What is Tychi Mcp?

Tychi Mcp is an agent-native MCP server that gives an AI agent a wallet—enabling onboarding, holding funds, sending, and paying under policy. It provides fast direct tools for wallet setup and operations, with private keys encrypted in ~/.tyi on the operator's machine and a hosted brain that parses intent and routes the LLM; signing never leaves the device.

How to use Tychi Mcp?

Install via npx -y @tychilabs/tyi-mcp@beta and configure the MCP host with the TYI_PASSWORD (set after onboarding) and optionally TYCHI_BRAIN_URL. The agent must follow a mandatory flow: first call tyi_route, then tyi_status to check readiness, then either a direct tool (onboard/create/import/switch/reset) for fast operations or tyi_chat for balance/sends/payments/policy. Never call tyi_chat when tyi_status.ready is false.

Key features of Tychi Mcp

  • Intent‑to‑tool routing via tyi_route (avoids slow misuse of tyi_chat)
  • Readiness gate tyi_status before any wallet action
  • Onboarding tools: tyi_onboard and tyi_onboard_schema
  • Wallet lifecycle: create, import (mnemonic/privkey), and switch wallets
  • Policy caps on spending enforced before signing
  • Local signing – private keys always on the operator machine
  • Gasless routing via UGF payment rails for cross‑chain settlement
  • Local audit log in ~/.tyi and reset capability (tyi_reset)

Use cases of Tychi Mcp

  • Allow an AI agent to hold and manage cryptocurrency funds under a configurable policy
  • Enable agents to perform on‑chain payments, transfers, and balance checks securely
  • Onboard an agent wallet for the first time with a password and LLM provider API key
  • Import an existing wallet from a mnemonic or private key (EVM, Solana, Sui)
  • Operate multiple wallets from a single keystore and switch between them

Frequently asked questions

1

How does Tychi Mcp keep private keys secure?

Private keys are encrypted and stored in `~/.tyi` on the operator’s machine; signing operations never leave the device. The hosted brain only routes LLM intent, not private material.

2

What dependencies or runtime does Tychi Mcp need?

It runs as a Node.js MCP server via `npx` and requires a hosted brain URL (default `http://hosted_brain.tychilabs.com`) and a keystore password set in the environment after onboarding. No additional runtime is needed beyond Node.js.

3

Where does Tychi Mcp store data?

All local data—encrypted keystore, audit logs, wallet configurations—is stored in the user‑specified directory (default `~/.tyi`). The hosted brain does not persist wallet keys.

4

What transports and authentication does Tychi Mcp support?

The server uses the MCP stdio transport. Authentication is via a keystore password (`TYI_PASSWORD` or `KEYSTORE_PASSWORD`) set in the MCP host environment after the onboarding step.

5

What are the known limits of Tychi Mcp?

`tyi_chat` is slower than direct tools and must only be used for balance, sends, payments, policy, limits, and history. Direct tools (onboard, create, import, switch, reset) should be used for all other wallet operations. The agent must never call `tyi_chat` when the status is not ready.
