Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

Run this in your terminal

claude mcp add tyi --env TYI_PASSWORD=your-value --env TYCHI_BRAIN_URL=your-value -- npx -y @tychilabs/tyi-mcp

Fill in the empty values before running it.

Open in Cursor

Common questions

Is Tychi MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: TYI_PASSWORD

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0-beta.8) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Tychi MCP (`@tychilabs/tyi-mcp`)

Give your AI agent a wallet — onboard, hold funds, send, and pay under policy.

Agent-native MCP server (stdio) for Cursor and other hosts. Nine tools: routing (tyi_route), readiness (tyi_status), onboarding, fast wallet lifecycle (create / import / switch), and tyi_chat for balances, sends, and policy-gated payments on Arbitrum One. Private keys encrypted in ~/.tyi on the operator machine; signing never leaves the device. Hosted Tychi brain parses intent and runs the LLM — configure TYCHI_BRAIN_URL (HTTPS recommended; see SECURITY.md).

Agents → @tychilabs/tyi-mcp@1.0.0-beta.8 · Humans → @tychilabs/tyi

What it does

Agent routing — tyi_route maps intent → correct tool (avoids slow misuse of tyi_chat)
Readiness gate — tyi_status checks mode before any wallet action
Onboarding — tyi_onboard + tyi_onboard_schema for first-time setup (password, LLM provider, API key)
Wallet lifecycle — tyi_create_wallet, tyi_import_wallet, tyi_switch_wallet (fast, no brain loop)
Agent chat — tyi_chat for balances, sends, transfers, payments, policy, limits, history
Multi-wallet — create, import, switch active wallet from one keystore
Policy caps — spend limits enforced before signing
Local signing — private keys in memory on operator machine only
Gasless routing — UGF payment rails for cross-chain gas settlement
Audit log — local activity trail in ~/.tyi
Reset — tyi_reset wipes local data when operator confirms

Beta ships on Arbitrum One (chain id 42161) — EVM balances, sends, and UGF gasless payments. More chains in registry; Solana/Sui import supported.

Arbitrum One

Onchain agent wallet on Arbitrum One — self-custody, local signing, UGF gas routing today:

Roadmap	What it unlocks
Automation	Policy-gated agents — recurring sends, triggers, scheduled flows
Trading	Spot swaps across Arbitrum liquidity — agent quotes, operator confirms
Lending	Supply on Arbitrum money markets — yield without leaving keystore
Borrowing	Collateralized borrow — cap-enforced, fully self-custodial

Agent flow (mandatory)

tyi_route → tyi_status

→ direct tool (onboard / create / import / switch / reset) ← FAST → tyi_chat (balance / send / pay / policy only) ← SLOW

Never call tyi_chat when tyi_status.ready is false.

Import seed or private key → tyi_import_wallet only (never via tyi_chat).

Tools

Tool	Use when
`tyi_route`	First — intent → tool map
`tyi_status`	Session start — ready? what's missing?
`tyi_onboard_schema`	Field schema before onboard
`tyi_onboard`	First setup or LLM-only setup
`tyi_create_wallet`	New wallet by name
`tyi_import_wallet`	Import mnemonic or privkey (EVM / Solana / Sui)
`tyi_switch_wallet`	Change active wallet
`tyi_reset`	Wipe `~/.tyi` (`confirm: true`)
`tyi_chat`	Balance, send, pay, transfer, policy, limits

Install

Pin the release (do not use floating @beta in production):

npx @tychilabs/tyi-mcp@1.0.0-beta.8

npx @tychilabs/tyi-mcp@1.0.0-beta.8 --tools

Security

See [SECURITY.md](./SECURITY.md) — trust model, brain transport (HTTP beta endpoint), sensitive tools, supply-chain pinning. No install scripts.

MCP host config

Repo includes .mcp.json (Open Plugins) for Cursor Directory. Set `TYI_PASSWORD` and `TYCHI_BRAIN_URL` in host env (HTTPS brain recommended).

"mcpServers": { "tychi": { "command": "npx", "args": ["@tychilabs/tyi-mcp@1.0.0-beta.8"], "env": { "TYI_PASSWORD": " ", "TYCHI_BRAIN_URL": " " } } } }

Beta default if unset in code: http://hosted_brain.tychilabs.com — use HTTPS self-host or trusted network only.

OpenClaw:

openclaw mcp set tychi '{"command":"npx","args":["@tychilabs/tyi-mcp@1.0.0-beta.8"],"env":{"TYI_PASSWORD":"<password>","TYCHI_BRAIN_URL":"<https brain URL>"}}'

openclaw mcp reload

Onboarding modes

Mode	Meaning
`fresh`	No wallet — run `tyi_onboard`
`llm_only`	Wallet exists, no LLM key — onboard LLM fields only
`ready`	OK for `tyi_chat`

Operator provides (never invent): keystore password, LLM provider + API key, optional mnemonic for import.

Prefer MCP env for TYI_PASSWORD over chat after onboard.

Field	Prompt
`password`	Keystore password for `~/.tyi` → later `TYI_PASSWORD` in MCP env
`agent_name`	Agent name (default `Tychi`)
`llm_provider`	`anthropic` \	`gemini` \	`openai` \	`groq`
`llm_api_key`	Provider API key (validated, stored encrypted on brain)
`mnemonic`	Optional import (fresh only)

Remove integration + data

tyi_reset with { "confirm": true } — wipes ~/.tyi
Remove TYI_PASSWORD from MCP env
OpenClaw: openclaw mcp unset tychi then openclaw mcp reload

Errors

Symptom	Action
`not_ready` on chat	Run onboard flow
`TYI_PASSWORD env required`	Set env after onboard; reload host
`no_llm_key` / missing `llm_key`	`tyi_onboard` llm_only
`partial install`	`tyi_reset` then fresh onboard
`fetch failed` on brain	Set `TYCHI_BRAIN_URL` explicitly; use HTTPS self-host or beta `http://hosted_brain.tychilabs.com`

Environment

Variable	Required	Default
`TYI_PASSWORD`	After onboard	—
`TYCHI_BRAIN_URL`	Recommended	`http://hosted_brain.tychilabs.com` (beta; prefer HTTPS override)
`TYI_DATA_DIR`	No	`~/.tyi`
`KEYSTORE_PASSWORD`	Alias	same as `TYI_PASSWORD`
