## Quality 89/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: 86 (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
- pass `tools.annotations`: 6 of 6 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: faa_delays_list_active_events (destructiveHint); faa_delays_list_reference (destructiveHint); faa_delays_get_airport_status (destructiveHint); …
- pass `tools.token_cost`: about 2,378 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`: 3 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`: deps.dev does not know @cyanheads/faa-traffic-delays-mcp-server@0.2.1, @cyanheads/faa-traffic-delays-mcp-server@0.2.1

- tools: 6, about 2,378 tokens to load them all
- tool set hash: e094134498ca43c2a0c8019959e38f84

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-14 `faa_delays_list_reference` changed (outputSchema)
- 2026-10-14 `faa_delays_list_advisories` changed (description, inputSchema, outputSchema)
  - before: List the ATCSCC advisories issued on one UTC date, newest first, from the FAA advisories database's per-date index: ground stops and delay programs as issued, proposed, revised, and canceled, required reroutes, flow constrained areas, operations plans, and CDM compression advisories, including those no longer active and those on past dates, which the NAS Status feed does not carry. Each row gives the advisory number, control element, subject, any further title lines (a reroute's name, constrained area, and valid period), and send time; its number and date open the full text with faa_delays_get_advisory. Narrow by categories or by control_element (an airport, its ICAO code, an ARTCC, or DCC for national advisories), and page with limit and offset.
  - after: List the ATCSCC advisories issued on one UTC date, newest first, from the FAA advisories database's per-date index: ground stops and delay programs as issued, proposed, revised, and canceled, required reroutes, flow constrained areas, operations plans, and CDM compression advisories, including those no longer active and those on past dates, which the NAS Status feed does not carry. Each row gives the advisory number, control element, subject, any further title lines (a reroute's name, constrained area, and valid period), and send time; its number and date open the full text with faa_delays_get_advisory. Narrow by categories, control_element (an airport, its ICAO code, an ARTCC, or DCC for national advisories), or query (literal case-insensitive subject/details text, such as an FCA name); filters combine before limit and offset paging.

## Tools (6)

- `faa_delays_get_advisory`: Get the full text of one ATCSCC advisory by its number and UTC date. faa_delays_list_advisories lists the advisories issued on a date with their numbers, and the advisory reference that faa_delays_list_active_events and faa_delays_get_airport_status return on program rows and faa_delays_get_operations_plan returns for the plan names one directly. Advisory text carries what the status feed omits: program rate by hour, delay assignment mode, scope, comments, and the operations plan's active constraints and runway closures. Advisory numbers restart at 1 each UTC day, and older advisories remain available.
- `faa_delays_get_airport_status`: Get the current FAA traffic management status for one or more US airports: a headline status, every active event (ground stop, Ground Delay Program with its delay profile, arrival or departure delay, closure, deicing) with reason and times, and the runway configuration and airport arrival rate. Every row carries the airport's ARTCC, and its coordinates come from the feed when the airport is listed (absent when the feed omits them) and from the NASR directory otherwise; both place a departure airport against a program's includedFacilities and departureScopeNm. Airports are FAA 3-character identifiers (SEA, ORD, JFK) or their ICAO codes (KSEA, PHNL); a code that names no US airport is rejected. The FAA feed lists only airports with an active event, so a known airport absent from it returns status no_active_events, and runway configuration is available only for listed airports.
- `faa_delays_get_operations_plan`: Get the FAA Command Center's current operations plan: terminal programs (possible ground stops and delay programs by airport) and en-route initiatives (route closures, severe-weather avoidance plans) expected later in the day, each with its planned UTC time and stated likelihood, plus current ATCSCC announcements. The advisory reference opens the full plan text with faa_delays_get_advisory, including active constraints and runway closures this summary omits.
- `faa_delays_list_active_events`: List every active FAA traffic management event across the National Airspace System in one call: ground stops, Ground Delay Programs, Airspace Flow Programs, arrival and departure delays, airport closures, closure NOTAMs, and deicing. Rows are sorted by severity (closures, ground stops, then GDPs and then AFPs each by average delay, arrival/departure delays by band maximum, closure NOTAMs, deicing) and carry the reason, delay figures, times, and an advisory reference for faa_delays_get_advisory. Use faa_delays_get_airport_status for the full detail of one airport, including its GDP delay profile and runway configuration.
- `faa_delays_list_advisories`: List the ATCSCC advisories issued on one UTC date, newest first, from the FAA advisories database's per-date index: ground stops and delay programs as issued, proposed, revised, and canceled, required reroutes, flow constrained areas, operations plans, and CDM compression advisories, including those no longer active and those on past dates, which the NAS Status feed does not carry. Each row gives the advisory number, control element, subject, any further title lines (a reroute's name, constrained area, and valid period), and send time; its number and date open the full text with faa_delays_get_advisory. Narrow by categories, control_element (an airport, its ICAO code, an ARTCC, or DCC for national advisories), or query (literal case-insensitive subject/details text, such as an FCA name); filters combine before limit and offset paging.
- `faa_delays_list_reference`: Decode the vocabulary the other faa_delays tools return: event types and their fields, traffic-management terms (AAR, EDCT, FCA, GDP, SWAP), ARTCC center codes, the FAA pacing airports with time zones, and accepted identifier formats.
