README

Crypto-Pegmon-MCP

An MCP server that tracks stablecoin peg integrity across multiple blockchains, helping AI agents detect depegging risks before they escalate.

Features

Stability Reports: Generate detailed reports assessing stablecoin peg stability, including maximum deviation and status (Stable, Moderately Stable, Unstable).
Real-Time Price Monitoring: Fetch current prices and calculate peg deviation from $1 for USD-pegged stablecoins.
Historical Data Analysis: Retrieve historical price data (up to 7 days by default) in Markdown table format.
Supported Stablecoins: Monitor 17 USD-pegged stablecoins, such as Tether (USDT), USD Coin (USDC), Dai (DAI), and yield-bearing tokens like Ethena Staked USDe (eUSDe).
User-Friendly Output: All data is presented in clean Markdown format for easy integration into reports or dashboards.

Usage

The server provides four tools, accessible via the MCP interface. Below are examples for each tool and prompt.

1. List Supported Stablecoins

Retrieve a list of supported stablecoins with their descriptions.

Prompt:

List all supported stablecoins with their descriptions.

Output:

2. Fetch Current Price

Get the current price and peg deviation for a specific stablecoin.

Prompt:
```
Get the current price of USDT.
```

Output:

**USDT Current Price**: $1.0002, Peg Deviation: 0.02%

3. Fetch Historical Data
