This MCP server, developed by Andy Brandt, enables AI assistants like Claude to interact with OpenAI's GPT models through a simple interface. It provides tools for creating and managing OpenAI assistants, starting conversation threads, and exchanging messages. The server integrates seamlessly with Claude Desktop on both macOS and Windows, bridging the capabilities of different AI platforms. By allowing Claude to leverage OpenAI's specialized GPT models, this implementation expands the knowledge and skills available to the AI assistant. It is particularly useful for scenarios requiring access to OpenAI's latest models, collaborative AI interactions, or specialized task delegation in AI-powered applications.

The RetellAI MCP server provides AI assistants with direct access to RetellAI's voice services for creating and managing phone conversations. Built by abhaybabbar, this implementation exposes tools for call management, agent configuration, phone number provisioning, and voice selection through the Model Context Protocol. The server connects to RetellAI's API using a provided API key and transforms requests and responses between MCP format and RetellAI's native format. It's particularly valuable for applications that need to initiate outbound calls, handle inbound calls, or create voice agents with specific personalities and capabilities for tasks like automated customer service, appointment scheduling, or information gathering.
