Provides web search capabilities using OpenAI's o3 model with configurable reasoning effort levels for finding current information and solving complex problems beyond traditional search engines.

This MCP server provides web search capabilities using OpenAI's o3 model, offering AI-powered search results through a single o3-search tool that accepts natural language queries. Built by @yoshiko-pg using TypeScript with the OpenAI SDK and MCP SDK, it leverages OpenAI's web_search_preview tool with configurable search context size and reasoning effort levels (low/medium/high) to deliver intelligent search responses for finding latest information and troubleshooting complex problems. The implementation features environment-based configuration, comprehensive error handling, and can be easily deployed via npx or local installation, making it valuable for AI assistants that need current web information and advanced reasoning capabilities beyond traditional search engines.
