Enables AI agents to securely query databases (PostgreSQL, SQLite, MySQL, DuckDB) with read-only defaults and multi-layer SQL injection prevention.

Knowledge graph for token-efficient code reviews. Builds a structural map of your codebase with Tree-sitter, tracks changes incrementally, and gives AI agents precise context via MCP tools. Features fixed multi-word search, qualified call resolution, dual-mode embedding (ONNX local + LiteLLM cloud), and output pagination.

MCP server for space weather and HF propagation conditions — live solar flux, Kp index, DSCOVR solar wind, X-ray flux, alerts, 27-day forecast, and band-by-band outlook through any MCP-compatible AI assistant.

Enables IOTA group lookup, island search, DXCC mapping, nearby groups, and programme statistics through any MCP-compatible AI assistant.

Enables AI assistants to query OMISS amateur-radio data from omiss.net's public pages, including the net schedule, nets currently on the air, member lookup, past net check-ins, the Statehood schedule, officers, awards and net statistics. No login or API key is required, with polite rate limiting and caching built in.

MCP server for QRZ.com — callsign lookups, DXCC entity resolution, and logbook queries through any MCP-compatible AI assistant.

Enables read-only querying of live and past amateur-radio nets and check-ins from NetLogger, with caching, rate limiting, and a consistent contract for future sources.

Enables amateur radio operators to plan meteor-scatter contacts by judging whether two stations can work each other on a given shower and when, reporting path length, radiant elevation at the path midpoint, and the radiant-to-path angle with a verdict of no, marginal, good, or best. Also provides shower peak timing, every published radiant solution per shower, live confirmed meteor counts and recent fireball reports, plus full source provenance and citations.

MCP server for ARRL Logbook of The World (LoTW) that enables querying confirmations, uploaded QSOs, DXCC credits, and user activity through any MCP-compatible AI assistant. Part of the qso-graph project, it is read-only and requires LoTW credentials for authenticated tools.

Enables querying WSPR beacon data including live spots, band activity, top beacons, propagation paths, and SNR trends through any MCP-compatible AI assistant.

Enables querying the 90 amateur ITU zones as the IARU publishes them, with each zone's ADIF DXCC and subdivision prefixes, boundary wording, and source citation, so users can find which zones cover a DXCC entity or subdivision, search zones by prefix or text, and check validity on a given date — all offline, without credentials.

MCP server for HamQTH.com — callsign lookup, DX cluster spots, Reverse Beacon Network, DXCC resolution, and more through any MCP-compatible AI assistant.

Currently enables MCP clients to retrieve service version and development status, with planned support for querying active and announced DXpeditions, their bands, modes, and QSL routes.

An MCP server for eQSL.cc that allows users to download incoming electronic QSL cards, verify specific contacts, and check Authenticity Guaranteed status. It enables natural language interaction with amateur radio logs and confirmation records through any MCP-compatible AI assistant.

Enables users to query live N1MM Logger+ contest state over UDP broadcasts, including recent QSO logs, bandmap spots, multiplier needs, score and rate, off-time pacing, and server diagnostics. Supports multiple stations and works with any MCP-compatible client through stdio or streamable HTTP.

Enables AI apps to ask what WSJT-X (and compatible JT-mode programs) is hearing by listening to its UDP feed read-only: who is calling CQ and what kind, recent decodes, stations heard, WSPR spots, and current dial frequency, mode and Tx status. It never transmits or changes settings, so it cannot answer a call, key a transmitter, or alter a configuration.

MCP server for Summits on the Air (SOTA) — live spots, activation alerts, summit info, and nearby summits through any MCP-compatible AI assistant.

Provides safe, typed access to Amateur Radio logging data with ADIF validation, parsing, spec search, and geospatial utilities for Maidenhead locators.

Enables clients to look up DARC local-club DOK codes and special event DOKs — district, club, purpose, callsign and sponsoring club — and to check whether a code was valid on a given QSO date, or to search by club, town, district or purpose. Runs fully offline with no network or authentication, and every answer cites its published source.

Provides access to government development, geography and land information data through a FastMCP interface, including data on new building plans processed by the Building Authority.
