MCP server for [Islands on the Air (IOTA)](https://www.iota-world.org/) — group lookup, island search, DXCC mapping, nearby groups, and programme statistics through any MCP-compatible AI assistant.

Part of the [qso-graph](https://qso-graph.io/) project. **No authentication required** — all IOTA data is public.

## Install

```bash
uvx iota-mcp            # run it; nothing to install
```

## Tools

| Tool | Description |
|------|-------------|
| `iota_lookup` | Look up an IOTA group by reference number (e.g., NA-005) |
| `iota_search` | Search groups and islands by name (e.g., Hawaii, Shetland) |
| `iota_islands` | List all islands and subgroups in an IOTA group |
| `iota_dxcc` | Bidirectional DXCC-to-IOTA mapping |
| `iota_stats` | Programme summary — totals by continent, most/least credited |
| `iota_nearby` | Find IOTA groups nearest to a lat/lon location |
| `get_version_info` | Service version + upstream programme data version (fleet identity attestation) |

## Quick Start

No credentials needed — just install and configure your MCP client.

### Configure your MCP client

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

## Data Source

Data comes from the official [IOTA website](https://www.iota-world.org/) JSON downloads:

- **fulllist.json** — complete group/subgroup/island hierarchy (~1.3 MB)
- **dxcc_matches_one_iota.json** — 1:1 DXCC-to-IOTA mapping (~3.5 KB)

Data is downloaded once and cached for 24 hours (IOTA refreshes daily at 00:00 UTC).

## Testing Without Network

```bash
IOTA_MCP_MOCK=1 iota-mcp
```

## MCP Inspector

```bash
iota-mcp --transport streamable-http --port 8010
```

Then open the MCP Inspector at `http://localhost:8010`.

## Development

```bash
git clone https://github.com/qso-graph/iota-mcp.git
cd iota-mcp
uv sync --group dev
uv run pytest
