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.

Supported Stablecoins

The server supports the following USD-pegged stablecoins:

Installation

Prerequisites

• Python 3.10 or higher

• uv (recommended for dependency management and running)

   git clone https://github.com/kukapay/crypto-pegmon-mcp.git cd crypto-pegmon-mcp

2. Install Dependencies: Using uv (recommended):

   uv sync

3. Run the Server: Using uv (recommended):

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.
