Common questions

Is N1mm 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 (0.4.0) reached the registry 12 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.

What can I use instead?

n1mm-mcp

MCP server for N1MM Logger+: live contest state — station, QSOs, bandmap, score and rate, multipliers, and contest clock — through any MCP-compatible AI assistant.

Data from N1MM Logger+'s UDP broadcasts on your local network. Part of the qso-graph project. No authentication required.

Install

uvx n1mm-mcp            # run it; nothing to install

Tools

Tool	Description	Key Parameters
`n1mm_current_state`	Station snapshot: connection, contest, operator, radios	station_name
`n1mm_lookup`	The callsign being entered (pre-log) plus current band and mode	station_name
`n1mm_contacts`	QSO log: recent contacts, edits and deletes	count, since, band, mode, call_pattern
`n1mm_bandmap`	Live spots, multiplier targets, band activity	band, mode, callsign, mults_only
`n1mm_performance`	Score, rate, bands, run/S&P, hourly timeline	band, mode
`n1mm_multipliers`	Multiplier grid, needs, value analysis	band
`n1mm_clock`	Contest timing, off-time, pacing	duration_hours, target_score, target_qsos, min_gap_minutes
`n1mm_diagnostics`	Server health, parse errors, memory	station_name
`n1mm_so2r`	Two radios: each radio now, transmit/receive focus, same-band warning, transmit time and minutes per band, focus swaps, QSOs per radio and while the other radio runs	station_name
`n1mm_network`	Every networked station: operator, radios, rate, idle time, band, shared score per contest call, stations sharing a band and mode, QSOs per operator	—
`n1mm_pileup`	DXpedition pileup: rate, unique calls, dupes, continents and countries calling, split, dead air	window_minutes
`get_version_info`	Service version + upstream spec version (fleet identity attestation)	—

Every tool except n1mm_network (which covers all stations) takes an optional station_name for multi-station setups.

Everything comes from N1MM's UDP broadcasts; n1mm-mcp never talks to a radio. N1MM reports transmitting only when it keys the radio itself (macros, its CW keyer), so a paddle or microphone PTT doesn't count as transmit time in n1mm_so2r.

What is N1MM Logger+?

N1MM Logger+ is a Windows contest logger. It can broadcast its state over UDP: contacts, spots, radio info and score. n1mm-mcp listens to those broadcasts and keeps the contest state in memory, so an assistant can answer questions about it. N1MM doesn't know it's there.

N1MM Logger+ (Windows)

│ UDP broadcast (port 12060, XML) ▼ n1mm-mcp (Python: the same PC, or any OS on the LAN) ├── UDP listener (background) ├── State engine (in memory, per StationName) │ MCP protocol (stdio) ▼ AI assistant

Quick Start

Turn on N1MM's broadcasts

In N1MM: Config → Configure Ports → Broadcast Data, and enable all message types.
Set the destination to 127.0.0.1:12060, N1MM's address for "this PC". n1mm-mcp listens there by default, and nothing outside the PC can reach it.

N1MM on another PC

Give one address of this PC and name who may send:

n1mm-mcp --bind 192.168.1.20 --allow 192.168.1.40

Then point N1MM at this PC's address (192.168.1.20:12060), or at your subnet's broadcast address (192.168.1.255:12060) to reach every PC on it. N1MM accepts several destinations separated by spaces. Don't use 255.255.255.255: N1MM's own documentation warns that it risks broadcasting to the internet (N1MM: External UDP Broadcasts).

--allow is required whenever --bind is a network address, and is repeatable for more than one PC. A datagram from any other address is dropped without being read, and counted — n1mm_diagnostics shows the count and the addresses, so traffic you did not expect is visible rather than silent.

`--bind 0.0.0.0` is refused. It listened on every interface at once, including whatever Wi-Fi a laptop happened to be joined to, and it cannot be narrowed afterwards. Name the interface you mean.

What the allow-list does and does not do

A UDP sender's address can be forged by anything on the same network, so the list keeps other machines out; it is not proof of who sent a datagram. What limits the damage is that n1mm-mcp only reads: it has no tool that writes to N1MM, your log, or anything else. A forged packet can therefore mislead you about contest state — a wrong frequency, a spot that was never spotted — but it cannot act, and nothing it contains is written anywhere. Treat the state as reported, not as verified, and run on a network you trust.

Configure your MCP client

n1mm-mcp works with any MCP-compatible client. Add the server config and restart. The tools appear automatically.
