"List of Easy-to-Use Free MCP Servers for Proof of Concept Development" matching MCP servers:

A Node.js and TypeScript server project that provides a simple starter example with Express.js web server, supporting hot-reload, testing, and modular structure.

An MCP server that provides real-time weather data, hourly forecasts, and daily summaries using the free Open-Meteo API with no API key required. It enables users to search for weather conditions by specific coordinates or city names across multiple measurement units.

Enables geospatial operations such as geocoding, routing, map visualization, satellite imagery, and weather data through a unified MCP interface, making Earth data accessible to non-programmers.

Enables keyless, read-only access to a wide range of public APIs (including weather, elevation, Japanese addresses, environment, science, and civic data) through MCP clients, with usage limits and abuse protection built in.

A customizable Model Context Protocol server implementation that enables AI models to interact with external tools including weather queries, Google search, and camera control functionality.

Enables querying and comparing operational numerical weather models, including global and regional, deterministic and ensemble, physics-based and AI forecasts, with a unified API.

Enables notes management, weather and news search, document ingestion and RAG-based semantic search using GroundX, with OpenAI GPT integration for summarization and completions.

A Model Context Protocol server that provides weather information using the Open-Meteo API, allowing users to get current weather for specific cities and retrieve weather data for date ranges.

A proof-of-concept MCP server that enables LLMs to read local text files and fetch real-time weather data through external tools.

Enables querying current weather conditions and 1–7 day forecasts by place name through natural language, using Open-Meteo without requiring an API key.

An MCP Server that provides weather information by ZIP code using Interzoid's API, allowing agents to retrieve current weather conditions based on postal codes.

An MCP server that provides access to the Interzoid GetWeatherCity API, allowing users to retrieve weather information for specified cities through natural language interactions.

Provides current weather and forecasts via OpenWeatherMap API, enabling users to query temperature, humidity, wind speed, and multi-step forecasts for any city.

A proof-of-concept MCP server that provides weather information using the Open-Meteo API, with tools for greeting, getting weather by coordinates, and by location name.

Integrates weather tools with Intercom, providing real-time weather alerts, forecasts, and personalized customer greetings using National Weather Service API data.

Enables natural language control of Homey Pro smart home systems, including devices, flows, zones, energy monitoring, weather, alarms, and system management, with 43 tools and troubleshooting prompts.

Enables AI assistants to access real-time weather data by city and manage HR operations including job applications, recruitment tracking, and interview scheduling through a unified, modular interface with live updates via SSE.

A remote MCP server that exposes a get_weather tool for real-time current weather queries of any city via the free wttr.in API, supporting Streamable HTTP transport.

Provides weather information for any city using the Open-Meteo API, deployed via Vercel for easy integration with MCP clients.

An MCP server that provides weather alerts and forecasts, system shutdown/restart, smart browser search, and screenshot capture.
