"An overview of knowledge graphs and their applications" 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 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 turning data into map images of countries, states, provinces, counties, continents, and the world, including choropleths, category maps, and pinned locations.

Cost-of-living and quality-of-life comparison across ~165 cities: take-home pay, the equivalent salary you'd need, and the safety-net deltas (childcare, healthcare, vacation, parental leave).

Finds marked hiking routes from OpenStreetMap filtered by locally-computed elevation gain, distance, loop shape, and car/chairlift access, providing consistent and tunable metrics instead of third-party scraped data.

Enables AI agents and hackathon teams to query Glendale, California hazard zones and city GIS data by address or coordinates, including nearby resources and dataset metadata for emergency-preparedness applications.

Persistent, shareable travel workspaces for AI agents. Build a complete itinerary as a private map link and hand it to the person — usable on their behalf where signup-walled travel tools are not. Six tools, no API key, no account. The trip rides in the link's fragment, so nothing is stored server-side. Hosted at https://thistripbtw.us/mcp — zero install — or npx thistripbtw-mcp over stdio.

MCP server that searches Japanese addresses and returns their locations as polygons or points using the open 住所LOD dataset, enabling geocoding, reverse geocoding, batch GeoJSON export, and map visualization.

Enables AI agents to perform due diligence on Irish properties by querying public datasets for planning applications, sold prices, flood risk, radon risk, and zoning.

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.

An MCP server that wraps the U.S. Army Corps of Engineers (USACE) Institute for Water Resources (IWR) River Mile Marker ArcGIS Feature Service, allowing LLMs to locate river mile markers on navigable U.S. rivers and answer 'what river mile am I at?' questions.

An MCP server that exposes the Wunder Mobility v2 end-user API as tools, enabling clients to browse vehicles, manage rentals, and create reservations on behalf of a signed-in user.

Unofficial MCP server for BUPT mobile academic system, enabling querying of today's empty classrooms, course schedules, and combined overview.

Drive Esri's ArcGIS Pro from an AI agent — the ArcGIS Pro counterpart to QGIS MCP. A headless ArcPy CLI plus an in-process .NET 8 add-in that exposes the live Pro session as MCP tools (ping, zoom_to, query, run_gp, export_layout) so an agent drives the running project while you watch.

An MCP server for querying land use plans and exporting cadastral maps as DXF files using VWorld Open API from the Korean Ministry of Land, Infrastructure and Transport.

The rush-gift-mcp server helps users en route to an appointment find last-minute gift recommendations and pickup stores along their route, considering time constraints, budget, and relationship. It provides AI-driven planning tools that calculate detour feasibility and generate appropriate gift messages.

Enables discovery and scoring of independent local businesses by inverting algorithmic rankings that favor chains, using Google Places API with an opinionated independence-scoring engine.

Provides AI agents access to OpenStreetMap's comprehensive tagging knowledge base, enabling tag queries, preset discovery, and validation of OSM tags for mapping applications.
