## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: media_receivable (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); media_closed (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); media_sources (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 957 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 9, about 957 tokens to load them all
- tool set hash: 463d5939055007fd8e170c14fd3bc106
- badge: [![protogrid quality](https://protogrid.dev/badge/global.rootz.dtv/broadcast.svg)](https://protogrid.dev/servers/global.rootz.dtv/broadcast)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (9)

- `media_closed`: Channels that have shut down, with the date they closed. Useful for checking whether a channel a model remembers still exists.
- `media_freshness`: How current this dataset is: when each source last ran, how many assertions are live versus expired, and the gaps we know we have.
- `media_outlets`: Search stations, networks and streaming channels by name, callsign, network or owner. Returns licence status, transmitter power and antenna height where filed.
- `media_receivable`: Which television transmitters reach a specific latitude and longitude, graded by real terrain between the tower and that point. Answers "what can I actually watch from here", which listings services cannot.
- `media_sources`: Where the data comes from, each with its licence and whether it may be redistributed.
- `media_station_readiness`: Whether a US television station website can be read by an AI assistant: which AI crawlers it blocks by name in robots.txt, whether it publishes llms.txt or /.well-known/ai, and whether it has structured data. Pass a callsign for one station, or nothing for the industry-wide summary broken down by owner group.
- `media_still_true`: Is a remembered claim about a programme still current? Returns when it was observed, whether it has expired, and what replaced it. This is the question a model cannot answer about its own training data.
- `media_verify`: Verify a signed record from this service. Pass an airing_id, or pass back a record you cached earlier with its signature and we will confirm it is byte-identical to what we signed. The public key and exact canonicalisation are at /.well-known/dtv-intel-signing.json so you can also verify offline without calling us.
- `media_whats_on`: What is airing right now, or at a given time. Returns programmes with descriptions and, for each, when the claim was observed and when it expires. Accepts free text.
