How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security49
- Malware scan not yet available for this package.Unverified
- No known CVEs affecting this package version or its production dependencies.Pass

Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to qso-graph/lotw-mcp). View diagnostics → Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_version_info Get Version Info ~84
Get lotw-mcp service version and upstream LoTW schema version. Returns the running PyPI version of lotw-mcp and the ARRL LoTW ADIF/CSV export schema in use. Use this to confirm fleet alignment across MCP deployments — agents can compare service_version and spec_version across servers to detect drift without going outside the MCP protocol.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
lotw_confirmations Lotw Confirmations ~131
Query confirmed QSL records from LoTW.
| Name | Type | Req | Description |
|---|---|---|---|
| band | – | – | Filter by ADIF band (e.g., '20M'). |
| callsign | – | – | Filter by worked station callsign. |
| detail | boolean | – | Include QSL station location data (default true). |
| dxcc | – | – | Filter by DXCC entity code. |

lotw_download Lotw Download ~162
Download your complete LoTW log as raw ADIF text. Returns the .adi file content — save to disk for import into your logger. Set qsl_only=True for confirmed QSLs only. Omit 'since' for full history. Warning: large logs may take 30-60 seconds (LoTW is slow).
