"openapi" matching MCP servers:

Enables automatic weather information retrieval through a custom MCP server integrated with OpenAI using Cloudflare tunnels. Demonstrates seamless function calling between OpenAI and custom MCP tools without manual intervention.

Enables querying Korean air quality forecasts, weekly ultrafine dust forecasts, high-concentration PM2.5 forecasts, particulate matter alarm statuses, ozone advisories, and yellow dust advisories from the AirKorea OpenAPI.

Provides weather data from OpenWeatherMap API through MCP tools and a REST API with OpenAPI support. Enables LLM agents to retrieve current weather, forecasts, and temperature ranges by city or coordinates.

Enables launching and monitoring SaferPlaces flood simulations directly from Claude chat, with credentials handled server-side. Tools are auto-generated from the SaferPlaces OpenAPI specification.

Exposes the getWeather and getTime tools over a stateless streamable-HTTP MCP endpoint at /mcp, so clients can look up weather for a location and the current time for a timezone through MCP tool calls. Running the same pure tool code as the app's OpenAPI surface, it lets you register the deployment as a remote MCP tool and compare MCP against custom-OpenAPI integration.
