Gistemp vs Magic MCP
A side-by-side look at the Gistemp and Magic MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Gistemp for aerospace & astrodynamics work as a local process; choose Magic MCP for architecture & design as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Gistemp when
- You need dedicated capabilities in the Aerospace & Astrodynamics domain.
- You prefer a local stdio subprocess transport.
- You want tools like
get_temperature_anomaly, get_latest_anomaly, get_zonal_anomalies.
Choose Magic MCP when
- You need dedicated capabilities in the Architecture & Design domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: API key required.
- You have the keys it needs:
TWENTY_FIRST_API_KEY, API_KEY_21ST.

Tools & capabilities
Gistemp tools 3
get_temperature_anomalyNASA GISTEMP surface temperature anomaly time series (degrees C from 1951-1980 baseline). Pick a region (global_land_ocean, global_land_only, northern_hemisphere, southern_hemisphere) and get monthly + annual + seasonal values back. Use for climate bets ("will 2026 be the hottest year on record"), trend comparisons, or cross-source consistency checks against HadCRUT5/Berkeley Earth. Annual frequency returns one row per year (Jan-Dec mean); monthly returns Jan..Dec per year.get_latest_anomalyMost recent NASA GISTEMP global land+ocean monthly anomaly, plus how it ranks against history. Returns the latest available month, the anomaly value (degrees C from 1951-1980 baseline), the rank of that value among all same-month observations since 1880, and a 12-month trailing mean. Cheaper than get_temperature_anomaly when you only need "what is the current reading and is it unusual."get_zonal_anomaliesNASA GISTEMP annual zonal anomalies (degrees C from 1951-1980 baseline) for 8 latitude bands: global, Northern Hemisphere, Southern Hemisphere, 24N-90N, 24S-24N (tropics), 90S-24S, 64N-90N (Arctic), 44S-24S, etc. Use for regional climate bets ("will the Arctic warm faster than the tropics in 2026") or bets framed around polar amplification.

Frequently asked questions
Gistemp is categorized under Aerospace & Astrodynamics and uses a local stdio subprocess. Magic MCP belongs to Architecture & Design and uses a local stdio subprocess. Pick Gistemp for aerospace & astrodynamics work and Magic MCP for architecture & design.
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.
Gistemp has no declared pricing — check the project's own site. Magic MCP is listed as a paid service. Auth: api key required. 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 gistemp and 21st-dev-magic-mcp as separate keys in the same mcpServers object, and your assistant will call tools from either one.
