Common questions

Is Wspr MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.6.1) reached the registry 9 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

wspr-mcp

MCP server for WSPR (Weak Signal Propagation Reporter) beacon data — live spots, band activity, top beacons, propagation paths, SNR trends, and more through any MCP-compatible AI assistant.

Data from wspr.live (~2.7 billion spots, 2008-present). Part of the qso-graph project. No authentication required — all public data.

Install

uvx wspr-mcp            # run it; nothing to install

`wspr_band_activity`	Per-band spot counts, station counts, distances, and SNR	hours
`wspr_top_beacons`	Top transmitters ranked by spot count or max distance	band, hours, sort_by (spots/distance), limit
`wspr_top_spotters`	Top receivers ranked by spot count or max distance	band, hours, sort_by (spots/distance), limit
`wspr_propagation`	Propagation between two locations — auto-widens to field-level proxy for sparse endpoints	tx, rx, band, hours
`wspr_grid_activity`	All WSPR activity in/out of a Maidenhead grid square	grid (2 or 4 char), band, hours
`wspr_longest_paths`	Longest distance WSPR paths in a time window	band, hours, min_distance, limit

`get_version_info`	Service version + upstream spec version (fleet identity attestation)	—

What is WSPR?

WSPR beacons transmit a 2-minute encoded signal at very low power (typically 200 mW to 5 W). Each decoded spot proves a propagation path exists between two locations on a specific band. With thousands of beacons worldwide transmitting 24/7, WSPR provides continuous, automated propagation monitoring across all HF bands.

Good Neighbour Policy

wspr.live is a volunteer-run service that mirrors all wsprnet.org data into a public ClickHouse database. We take our responsibility as a good neighbour seriously:

Measure	Detail
Rate limiting	3 seconds between requests (20 req/min max)
Circuit breaker	Opens after 3 consecutive failures; exponential backoff up to 5 minutes. Prevents hammering a struggling service.
Time-bounded queries	Every query filters by time (max 72 hours). No unbounded full-table scans.
Band filtering	Queries filter by band whenever the user provides one — this hits wspr.live's indexes efficiently.
Column selection	We SELECT only the columns each tool needs (8-10 per query), never `SELECT *`.
Result limits	All queries cap results (200 spots, 50 leaderboard entries).
Response caching	2-10 minute TTL per tool. Identical queries within the window hit local cache with zero network traffic.
Request timeout	20-second timeout — we don't hold connections open on a shared service.
User-Agent header	Every request identifies itself as `wspr-mcp/{version}` so the operators can reach us if needed.

If wspr.live is down or overloaded, the circuit breaker backs off automatically. We don't retry in a tight loop.
