Tychi MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 43 installs a week from npm. Last commit 15 Jun 2026.
Agent-native self-custody wallet MCP: onboard, wallets, Arbitrum sends, policy-gated payments.
Today is the operative word: we check Tychi MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
TYI_PASSWORD (Keystore password for ~/.tyi (set after tyi_onboard)), TYCHI_BRAIN_URL (Tychi brain API URL (HTTPS recommended)).
