• Transaction history retrieval
• Model Context Protocol compliant API
• Support for Flask web server and WebSocket connections
• Detailed logging and error handling

• pip

Setup

1. Clone the repository:

   git clone https://github.com/olaxbt/solana-vault-mcp.git
   cd solana-vault-mcp
   

2. Create and activate a virtual environment:

   python -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate
   

3. Install dependencies:

   pip install -r requirements.txt
   

4. Create a .env file based on .env.example:

   cp .env.example .env
   

5. Edit the .env file to add your Solana private key and RPC URL.

Usage
