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

crypto-pegmon-mcp MCP server

License Python Status

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: 
    **Supported USD-Pegged Stablecoins**:

| Symbol     | Description                                            |
|------------|--------------------------------------------------------|
| USDT       | Tether s USD-pegged stablecoin, centrally issued.      |
| USDC       | Circle s USD-backed stablecoin, widely used in DeFi.   |
| ...        | ...                                                    |

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

Retrieve historical price data for a stablecoin over a specified number of days (default: 7).

  • Prompt: 
    Show the price history of USDC for the last 7 days.
  • Output: 
    **USDC Historical Data (Last 7 Days)**:

| Date       | Price  | Deviation (%) |
|------------|--------|---------------|
| 2025-04-29 | 1.0001 | 0.0100        |
| 2025-04-30 | 0.9998 | -0.0200       |
| ...        | ...    | ...           |

4. Analyze Peg Stability

Generate a comprehensive stability report for a stablecoin, including historical data, current price, and analysis.

  • Prompt: 
    Analyze the peg stability of DAI over the past week.
  • Output: 
    - **DAI Historical Data (Last 7 Days)**:
  | Date       | Price  | Deviation (%) |
  |------------|--------|---------------|
  | 2025-04-29 | 1.0003 | 0.0300        |
  | ...        | ...    | ...           |
- **DAI Current Price**: $1.0000, Peg Deviation: 0.00%
- **Stability Analysis for DAI**:
  - Maximum Deviation: 0.15%
  - Stability Status: Stable
  - Note: Deviations > 3% indicate potential depegging risks.
