What is the OTP-MCP Server?

The OTP-MCP server is a server based on the Model Context Protocol (MCP), specifically designed to generate one-time passwords (OTP). It supports both the Totp and Hotp algorithms and can be integrated with AI assistants and applications in multiple ways.

How to use the OTP-MCP Server?

Run the server through the command line. You can choose different transmission protocols (such as STDIO, SSE, or HTTP Stream), and then obtain one-time passwords when needed. Configuration can be adjusted using command-line parameters or environment variables.

Applicable Scenarios

Suitable for scenarios that require secure verification, such as login authentication, API key management, device pairing, etc. It is particularly suitable for use in conjunction with AI assistants to provide users with a secure interaction experience.

Main Features

Supports Multiple OTP Algorithms
Supports the Totp (time-based) and Hotp (HMAC-based) algorithms to meet the security requirements of different scenarios.
Multi-Protocol Support
Supports multiple transmission protocols such as STDIO, SSE, and HTTP Stream, facilitating integration with various applications and services.
Easy to Configure
The server can be easily configured via command-line parameters or environment variables, including the database path, host, and port, etc.
Advantages
Provides highly secure one-time password generation to prevent replay attacks
Supports multiple transmission protocols, with strong compatibility
Limitations
Requires a certain amount of technical knowledge for configuration and use
Depends on correct settings; otherwise, security may be affected

How to Use

Install the Server
Install the otp-mcp-server package using uvx or pip.
Start the Server
Select the transmission protocol as needed and run the server.
Configure the Connection
Configure the MCP server connection information, such as the address and port, in the target application.

Usage Examples

Integrate with the Claude Desktop Application
Configure the OTP-MCP server as the MCP server for the Claude desktop application to achieve secure login verification.
Web Application Security Verification
Use the HTTP stream protocol to communicate with the OTP-MCP server in a web application to implement two-factor verification during user login.
