"An introduction to SQL and database queries" matching MCP servers:

A local MCP server that integrates FastMCP with OpenAI to enable natural language queries for current weather, forecasts, and currency conversion using ExchangeRate-API and Open-Meteo.

Enables conversational spatial SQL queries in plain English, turning natural language questions into validated PostGIS operations and rendering results as GeoJSON on an interactive map.

Enables AI assistants to validate and standardize US addresses using the official USPS Address Validation API with secure OAuth2 authentication.

A self-contained MCP server that gives AI agents the ability to calculate high-precision astronomical data. It provides tropical zodiac coordinates, planetary speeds, retrograde detection, and house cusps using the trusted Swiss Ephemeris engine. 100%

Enables spatial analysis of large remote GeoParquet files directly from object storage without downloading or importing data, using DuckDB's predicate and projection pushdown to answer queries efficiently.

Provides live California road conditions, route planning, and an AI assistant over MCP, enabling natural-language queries about traffic, closures, chain controls, and more.

MCP server that provides statistically rigorous weather and climate context by exposing the Baseline API as agent tools, enabling queries about climate conditions and comparisons against historical data.

An MCP server that lets LLMs query USGS NHDPlus HR hydrography data—streams, rivers, lakes, stream gages, and watershed boundaries—via point or GeoJSON geometry intersection queries.

Enables AI assistants to scrape Google Maps business data (names, addresses, phones, emails, websites, ratings, etc.) through natural language queries, with tools for synchronous and asynchronous scraping and credit checking.

Enables querying GeoIP2, GeoLite2, and custom MMDB databases through the Model Context Protocol for IP lookups, filtered network queries, resumable pages, and MaxMind database downloads.

Connects MCP-compatible AI clients to BMLT root servers, enabling natural language queries for NA meeting data including search by location, day, format, and more.

Enables on-demand weather queries for up to three named locations via Open-Meteo, supporting current conditions, forecasts, rain probability, and conversational location management in English or Japanese.

Provides comprehensive weather data (forecasts, historical, air quality, marine) from Open-Meteo through 12 tools, with support for single and batch location queries.

An MCP server that finds great espresso cafes using a curated database of specialty coffee shops and a transparent scoring algorithm, with a strong bias against flavored syrups and mass-market chains.

Enables natural language search and retrieval of data from Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) Data Platform, including location-based queries, attribute filtering, and data visualization capabilities.

Provides real-time weather temperature queries for any city with an interactive UI form, using Open-Meteo API (no API key needed).

MCP server that provides AI assistants access to Oklahoma Corporation Commission public GIS datasets, enabling dataset search, layer metadata retrieval, and attribute/spatial queries on ArcGIS Hub data.

Global postal code lookups, validation, and city search for 240+ countries with timezone, admin region, and elevation metadata. Sub-10ms responses at $0.000028/query with 1,000 free queries on signup.

Thirteen read-only Google Maps Platform tools for an agent: where a place is, what is around it, how long it takes to get there, and what the conditions are when it arrives.

An MCP server that exposes Charlotte, NC and Mecklenburg County open data as tools for an LLM agent, enabling queries about trash pickup, parcels, zoning, crime, and more by geocoding addresses and querying live ArcGIS layers.
