Installation

Prerequisites

• Python 3.10 or higher

• Privy.io account with API credentials

Quick Start with uvx (Recommended)

The easiest way to use this MCP server is with uvx, which automatically fetches the package from PyPI:

uvx privy-mcp-server

No installation needed! Configure your MCP client (see Usage below) and you're ready to go.

Manual Installation (Development)

For local development:

1. Clone the repository:

git clone https://github.com/incentivai-io/privy-mcp-server.git
cd privy-mcp-server

2. Create virtual environment:

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

3. Install dependencies:

pip install -e .

4. Configure environment variables:

cp .env.example .env

Edit .env and add your Privy credentials:

PRIVY_APP_ID=your_app_id_here
PRIVY_APP_SECRET=your_app_secret_here

Get your credentials: Dashboard → App Settings → Basics on Privy.io

Usage

Running the Server

Run directly with Python:

python -m privy_mcp

Or use the MCP inspector for testing:

npx @modelcontextprotocol/inspector python -m privy_mcp

For example, from the project directory:

npx @modelcontextprotocol/inspector python -m privy_mcp

Configuring with Claude Desktop

Add to your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

Using uvx (Recommended)

{
  "mcpServers": {
    "privy": {
      "command": "uvx",
      "args": ["privy-mcp-server"],
      "env": {
        "PRIVY_APP_ID": "your_app_id_here",
        "PRIVY_APP_SECRET": "your_app_secret_here"
      }
    }
  }
}

Using local Python installation

{
  "mcpServers": {
    "privy": {
      "command": "python",
      "args": ["-m", "privy_mcp"],
      "env": {
        "PRIVY_APP_ID": "your_app_id_here",
        "PRIVY_APP_SECRET": "your_app_secret_here"
      }
    }
  }
}

Restart Claude Desktop after configuration.

Security Considerations

• Never commit .env file or expose API credentials

• Store credentials securely using environment variables or secrets management

• API credentials have full access to your Privy application

• This is a defensive security tool - do not use for malicious purposes

• Review Privy's security documentation: docs.privy.io/security

Troubleshooting

Authentication Errors

• Verify PRIVY_APP_ID and PRIVY_APP_SECRET are correct

• Check credentials at Dashboard → App Settings → Basics

• Ensure environment variables are loaded

Rate Limit Errors

• Reduce request frequency

• Implement exponential backoff

• Contact Privy support for limit increases

Connection Errors

• Verify internet connectivity

• Check Privy API status

• Ensure firewall allows HTTPS requests
