Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 1435 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name clarke.

  • Pass
    Lists tools

    tools/list returned 5 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 1435 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 1435 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    7 of 13 parameters have a description (54%). The bar is 80%.

  • Fail
    Safety hints

    5 tools set neither readOnlyHint nor destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Pass
    Repo owner matches

    The GitHub repository owner matches the namespace login.

  • Pass
    Recently updated

    Updated 2026-10-22T11:36:09.999703Z, within 180 days.

    Open-source licence

    The GitHub licence lookup has not returned an OSI result yet.

Capabilities

Tools 5

clarke_get_slot

Agent slot record for one GEO position by slug (e.g. '19-2e' for 19.2E, '101w' for 101W). Operator identity is operatorMix, with raw source strings on each share. operatorIdentity is split when more than one canonical operator is in the occupancy window, single when one is, none when the window has no attributed operator. Also returns occupancy observations (tleEpoch and tleStale), FCC authorizations, dispute records, ituRecorded, and source vintage (tleEpochMin, tleEpochMax, tleStale, tleStaleAfterDays 45), with provenance on occupancy, UCS, FCC, license, and rights. tleStale is true only for a TLE that supplied occupancy and is older than 45 days. UCS fallback does not invent a TLE epoch. ITU filings are not in this product. ITU Space Explorer is the current ITU source. SNS Online shut down in January 2025 (ituRecorded is not_in_product). TLE longitude is a tracked position, not an FCC or ITU assignment.

Discovered
clarke_get_terminal

Agent slot record for one GEO position. Same payload as clarke_get_slot: operatorMix as the occupancy identity, FCC rows, disputes, ituRecorded, and source vintage including tleStale (older than 45 days). operatorIdentity split means the window is shared. ITU filings are not in this product. ITU Space Explorer is the current ITU source. SNS Online shut down in January 2025 (ituRecorded is not_in_product). TLE longitude is a tracked position, not an FCC or ITU assignment.

Discovered
clarke_list_deltas

On-ingest change feed for GEO slot occupancy, FCC rows, and disputes (Slot Index delta feed, edition 2). coverage is bootstrap when fewer than two registry snapshots are stored, and ingest_deltas once a later snapshot exists. Each change has slug, longitude when available, detectedAt, source vintage, before and after, and provenance. Occupancy changes are enter, leave, authority_flip, and tle_epoch. tle_epoch is a TLE epoch change or a 45 day stale transition on a TLE used for occupancy. Bootstrap does not invent occupancy history. FCC changes are new, lapsed, licensee, status, and as_of when a snapshot does not store parsed workbook rows. When both snapshots store parsed data/ssal.xlsx rows, filing diffs for that interval are new, removed, and changed. removed is a call sign that left the workbook. changed is the same call sign with a different orbital location, satellite name, licensee, administration, service, frequency range, in-orbit date, grant status, or notes. Dispute changes are appear, clear, and kind. ITU filings are not in this product. ITU Space Explorer is the current ITU source. SNS Online shut down in January 2025. TLE longitude is a tracked position, not an FCC or ITU assignment. satellite_relocated rows are not occupancy changes. Optional filters: slug, domain (occupancy, fcc, dispute), since (exclusive ISO-8601 UTC). The public page keeps at most 40 changes and about 48 KB of change JSON. A timestamp with many rows is split. truncated is true when more changes matched. Pass after from nextAfter to continue. since stays an exclusive time filter. nextSince is set only when the page ended on a timestamp boundary.

Discovered
clarke_list_satellites

List GEO satellites from the UCS Satellite Database, optionally filtered by operator or owner country. Returns up to `limit` rows (default 100; max 1000).

Discovered
clarke_list_slots

List GEO slots in the Clarke registry (curated positions merged with UCS-derived positions). The default is a compact page of 50: slug, label, longitude, region, operatorIdentity (split, single, or none), country, status, and satCount. Pass offset to continue. view=full returns occupancy observations (tleEpoch and tleStale, older than 45 days when a TLE supplied occupancy), operatorMix, FCC rows, disputes, and source vintage, in pages of 10 (max 25). all=true is the explicit full list for that view and is large when view is full. The human Terminal models are not in either view. ITU filings are not in this product. ITU Space Explorer is the current ITU source. SNS Online shut down in January 2025 (ituRecorded is not_in_product on the full record). TLE longitude is a tracked position, not an FCC or ITU assignment.
