mcp-server-usdd

An MCP server for the USDD protocol across TRON, Ethereum, and BNB Smart Chain (plus internal testnets). Covers Vault/CDP, PSM, USDD Savings, token transfers, and protocol analytics.

Scope

Current implementation covers:

Vault lifecycle: open, deposit collateral, mint USDD, repay, withdraw, close
PSM lifecycle: inspect fees and routes, swap into USDD, swap out of USDD
Savings lifecycle: inspect USDD Savings, deposit, withdraw
Risk and monitoring for vaults: summaries, oracle status, collateral buffers
Token preflight checks: balances, allowances, approvals
Token transfers: two-step preview → confirm flow for TRX, TRC20, and EVM native/ERC20
Protocol analytics: chain metrics, collateral prices, PSM route metrics, treasury, Smart Allocator, proof of reserve

Supported Networks

Network	Key	Notes
TRON	`tron`	TRON-native vault and PSM support
Ethereum	`eth`	Vault, PSM, USDD Savings
BNB Smart Chain	`bsc`	Mirrors ETH deployment structure
TRON Nile	`tron_nile`	Internal testnet deployment
Ethereum Sepolia	`eth_sepolia`	Internal testnet deployment
BSC Testnet	`bsc_testnet`	Internal testnet deployment

Prerequisites

Node.js 24.22.1 LTS is required exactly for development and deployment (nvm use reads the repository’s .nvmrc)
- Every other Node.js version is rejected so the tested runtime and the 2026-10-21 security fixes remain consistent across environments
Optional but recommended:
- TRONGRID_API_KEY for more reliable TRON access
- dedicated TRON_FULL_NODE and TRON_NILE_FULL_NODE
- dedicated ETH_RPC_URL
- dedicated BSC_RPC_URL
- dedicated ETH_SEPOLIA_RPC_URL and BSC_TESTNET_RPC_URL

Developer

Installation

git clone https://github.com/decentralized-usd/mcp-server-usdd
cd mcp-server-usdd
nvm install
nvm use
npm ci

Usage

npm start
npm run start:http
npm run dev

Configuration

Wallet Modes

The server supports two signing modes:

Browser mode (recommended): connect a TronLink-compatible browser wallet and sign in browser.
Agent mode: use encrypted local private keys stored in ~/.agent-wallet/.

For TRON writes, each Claude session shows a one-time signing-mode confirmation reminder before the first write.

You can also manage wallets via CLI or MCP tools:

CLI (agent-wallet)
