Magic MCP vs Aviation Weather MCP Server
A side-by-side look at the Magic MCP and Aviation Weather MCP Server MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Magic MCP for architecture & design work as a local process; choose Aviation Weather MCP Server for aerospace & astrodynamics as a local process. You can also run both side by side in one mcpServers block.

Aviation Weather MCP Server tools 5
aviation_find_stationsResolve airports and weather stations by identifier, bounding box, or US state. Returns ICAO/IATA/FAA IDs, coordinates, elevation, and available data types.aviation_get_metarGet current weather observations (METARs) for named airports, or survey every reporting station in a bounding box. Returns decoded wind, visibility, ceiling, present weather, temp/dewpoint, altimeter, cloud layers, flight category (VFR/MVFR/IFR/LIFR), and the raw METAR string.aviation_get_tafGet Terminal Aerodrome Forecasts for one or more airports. Returns each forecast period with valid times, surface wind, low-level wind shear, visibility, decoded weather, cloud layers, and vertical visibility into a forecast obscuration, plus the raw TAF string.aviation_get_pirepsGet recent Pilot Reports near an airport or within a bounding box. Returns decoded turbulence, icing, and cloud reports with altitude, aircraft type, intensity, outside air temperature, wind aloft, flight weather, and the raw PIREP string.aviation_get_advisoriesGet domestic/international SIGMETs and Center Weather Advisories. Returns source coverage, hazard, severity, altitude, validity, movement, multipart geometry and original bulletins; omitted facts stay null.

Frequently asked questions
Magic MCP is categorized under Architecture & Design and uses a local stdio subprocess. Aviation Weather MCP Server belongs to Aerospace & Astrodynamics and uses a local stdio subprocess. Pick Magic MCP for architecture & design work and Aviation Weather MCP Server for aerospace & astrodynamics.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Magic MCP is listed as a paid service. Auth: api key required. Aviation Weather MCP Server has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add 21st-dev-magic-mcp and aviation-weather-mcp-server as separate keys in the same mcpServers object, and your assistant will call tools from either one.
