NASA GIBS MCP — the satellite-imagery layer catalogue behind Worldview.
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
NASA GIBS — the ~1,300-layer global satellite imagery catalogue behind NASA Worldview, with daily true-colour mosaics, thermal anomalies, sea-surface temperature, aerosols, snow and ice cover and night lights, most of them with a multi-decade daily time series.
Part of Pipeworx — an MCP gateway connecting AI agents to 1683+ live data sources.
Tools
gibs_list_layers(query?, projection?, limit?)— search the catalogue by subject or
identifier; returns each layer's id, title, grid and available date range.
gibs_layer_info(layer, projection?)— one layer's full time coverage, native
resolution, format, extent, colour map and legend URLs, and tile template.
gibs_tile_url(layer, date?, latitude?, longitude?, zoom?, tile_row?, tile_col?, projection?)—
a ready-to-fetch image tile URL, with the tile's own geographic bounds.
Auth
Keyless. No registration, no rate-limit headers.
Data sources
- —
the layer catalogue, one document per projection (epsg4326, epsg3857, epsg3413, epsg3031).
Things the next person would otherwise rediscover
- There is no JSON layer index. The WMTS capabilities XML is the only
machine-readable catalogue and it is ~5 MB per projection. It is parsed once per isolate and the (much smaller) result cached in module scope for 6 hours; a per-call re-parse would spend seconds of CPU on a document that changes about once a day. The cache is populated only inside a request — never at module load, where the Workers runtime reports Date.now() as 1970 and every entry would read as infinitely stale.
- Each layer has several `` templates. Only
one carries {Time}; that is the one worth handing a caller. The others drop the date silently and serve whatever GIBS considers current.
- `MatrixWidth` is not a power of two (levels

Questions
What is the mcp-nasa-gibs MCP server?
NASA GIBS MCP — the satellite-imagery layer catalogue behind Worldview.
What tools does mcp-nasa-gibs expose?
2 in total: 2 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is mcp-nasa-gibs safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does mcp-nasa-gibs need?
No credential environment variables were found in its source, so it appears to need none.
How does mcp-nasa-gibs run?
It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as @pipeworx/mcp-nasa-gibs at 0.1.1.
How current is this page?
The grade is for one exact copy of the source (63ab0e7516ce), read on 2026-10-11. The repository is watched and re-audited when it changes.
