An MCP server (and a live map) for the Pentagon's declassified UAP files.

On July 10, 2026, the U.S. Department of War published PURSUE Release 04 on war.gov/UFO. uap-pulse now bundles all four releases: 334 U.S. records, plus 16 curated official-government cases from 12 nations — 350 records total, spanning 1944–2026.

Official sources only. U.S. PURSUE records are public domain under 17 U.S.C. § 105. The international layer links to official national archives; rights remain with each originating source. No scraped civilian databases. Not affiliated with or endorsed by any government.

Use it as an MCP server

Your agent can search all 350 records by release, location, agency, era, or type — and pull the direct official source link for each.

Claude Desktop / any MCP client — add to your config:

json

{
  "mcpServers": {
    "uap-pulse": { "command": "npx", "args": ["-y", "uap-pulse"] }
  }
}

That's it — no API key, no auth, no cost. The data ships with the package.

HTTP (v2 stateless)

Default is stdio. Optional Streamable HTTP — no session id, JSON responses, loopback only:

bash

npx -y uap-pulse --http
# GET  http://127.0.0.1:3000/health
# POST http://127.0.0.1:3000/mcp   (sessionless)

Env: UAP_PULSE_HOST, UAP_PULSE_PORT, UAP_PULSE_TRANSPORT=http.

Tools

Tool	What it does
`search_sightings`	Search by `release` (1–4), free text, agency, type, year range, or location.
`search_nearby`	Incidents within a radius (km) of a lat/lng, sorted by distance.
`get_sighting`	Full record for one file id (e.g. `pursue-042`) + the `war.gov` link.
`full_text_search`	Relevance-ranked search across titles, locations, and descriptions.
`notable_cases`	Curated historically significant groups with source records.
`hotspots`	The locations with the most declassified records.
`stats`	Totals + breakdowns by release, agency, file type, and era.
`timeline`	Records per decade (or year), 1944 → 2026.
`timeline_data`	Per-period records with coordinates for maps and animation.

Example — "What UAP files mention the Moon?" → search_sightings({ location: "Moon" }) → NASA Gemini/Apollo records with their war.gov links.

Latest release — search_sightings({ release: 4, limit: 100 }) → all 40 files released on July 10, including the 1949 Los Alamos conference transcript, Project Sign records, new sensor videos, and STS-80 images.

The live map

A 3D globe of every geolocatable record — points pulse where the sightings cluster, colored by agency, filterable by era (WWII Foo Fighters → the Navy Era). Click a hotspot to read the files and open them on war.gov. Off-world records (Moon, orbit) get their own panel.

Run it locally:

bash

cd site && python3 -m http.server 8080   # then open http://localhost:8080

Or deploy the site/ folder to Vercel (static, no build step).
