What changed 6

Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 29 October 2026. No other catalogue keeps this.

29 Oct 3 tool descriptions were rewritten nasa_power_get_climatology, nasa_power_get_timeseries, nasa_power_search_parameters

and 2 more, back to 29 October 2026

Nothing serious here today

Today is the operative word: we check Nasa Power MCP Server every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

nasa

nasa_power_compare_locations

Compare 2–10 labeled coordinates with a shared parameter selection and window; climatology is the default resolution. Duplicate labels retain separate input-position identities. Returns per-site provenance and valid-only annual/seasonal summaries; operational site failures preserve successes. Optional numeric sort uses observation means, monthly annual records or climatology ANN, with nulls last and stable ties; differing or unknown units cannot sort. Oversized observations and summaries stage completely; summaryDatasets handles and summaryIndex preserve complete ordered summary arrays.

nasa_power_dataframe_describe

Inspect table schemas, physical units and original scientific provenance within a canvas_id returned by a producing POWER tool. Tokens are process-local capabilities; only the supplied canvas is inspected.

nasa_power_dataframe_query

Run one read-only SELECT over tables in an explicitly supplied canvas_id. Inspect names and units with nasa_power_dataframe_describe. External files, imports, writes and system catalogs are refused. Returns at most 1,000 rows and 40,000 JSON characters; truncated rowCount counts only materialized rows.

nasa_power_get_climatology

Retrieve complete monthly and annual climatology at latitude/longitude. Optionally supply both startYear and endYear; omitted years use the source product range. Use nasa_power_list_reference for presets and tilted solar aliases. Small profiles remain inline; larger profiles return a complete table handle and bounded preview, preserving orientation text. Oversized summaries stage as summaryDataset with exact summaryCount, queried in summaryIndex order. Supply canvas_id to reuse a returned workspace.

nasa_power_get_region

Retrieve one parameter over ordered latitude/longitude bounds spanning 2–10 degrees per axis, at daily, monthly or climatology resolution. Regional climatology uses the precomputed source period and accepts no year fields; use nasa_power_get_climatology for custom years at a point. Split antimeridian regions into separate calls. Returns cell identities and separate per-period equal-weight cell statistics, not area-weighted estimates. Oversized observations and summaries stage completely with previews, exact counts and SQL handles; query summaryDataset in summaryIndex order.

nasa_power_get_timeseries

Retrieve complete hourly, daily or monthly observations at latitude/longitude. Hourly and daily require startDate/endDate; monthly requires startYear/endYear. Use nasa_power_search_parameters for codes and nasa_power_list_reference for presets. Large results return a full-table canvas handle and preview; oversized summaries stage as summaryDataset with exact summaryCount, queried in summaryIndex order.

nasa_power_list_reference

Explain exact presets, communities and units, source coverage, missing values, wind corrections or current dataframe availability. Choose topic presets before a producing call, or coverage when revising a date window. Reference entries include public documentation and verification dates.

nasa_power_search_parameters

Find parameter codes supported by a community and temporalResolution. Every whitespace-separated filter token must match code, name or definition, ignoring case. Filtering covers the complete dictionary before sorted pagination. Codes NASA lists but does not serve at that resolution are left out, and a notice names any the filter matched. Blank filter browses all codes; pass returned codes to a producing tool.

Nasa Power MCP Server — questions

Answers built from our own checks of this server.

What can Nasa Power MCP Server do?

It exposes 8 tools, read directly from the server on our last check. Among them: nasa_power_compare_locations, nasa_power_dataframe_describe, nasa_power_dataframe_query, nasa_power_get_climatology, nasa_power_get_region, nasa_power_get_timeseries and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Nasa Power MCP Server working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 543 ms. The bar chart above shows every period we have measured.

How do I connect Nasa Power MCP Server?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Nasa Power MCP Server need an API key?

No. Nasa Power MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Nasa Power MCP Server?

It answers our handshake in 543 ms on average, which is faster than 22% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Nasa Power MCP Server?

The npm package @cyanheads/nasa-power-mcp-server was installed 895 times in the last week. Week over week that is +5165%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Nasa Power MCP Server open source?

The code is open source: it is published under the Apache-2.0 licence, written in TypeScript and 2 stars on GitHub. The licence covers the code in the repository, not the hosted service at nasa-power.caseyjhand.com, which runs on its operator's own terms.
