Category Maps and Location
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability55
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1141 tokens (~228/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management3
- Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage85
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 54% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

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 →
clarke_get_slot ~251
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.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Slot slug, e.g. '19-2e' |
No output schema declared.
No examples provided.
clarke_get_terminal ~133
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.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Slot slug, e.g. '101w' |
No output schema declared.
No examples provided.
clarke_list_deltas ~446
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.
| Name | Type | Req | Description |
|---|---|---|---|
| after | string | – | Exclusive change id from nextAfter |
| domain | string | – | – |
| since | string | – | Exclusive time filter. ISO-8601 UTC or YYYY-MM-DD HH:MM:SS |
| slug | string | – | Registry or FCC slug, e.g. '101w' or '101-2w' |
No output schema declared.

clarke_list_satellites ~68
List GEO satellites from the UCS Satellite Database, optionally filtered by operator or owner country. Returns up to `limit` rows (default 100; max 1000).
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | – |
| operator | string | – | – |
| ownerCountry | string | – | – |
No output schema declared.
No examples provided.
clarke_list_slots ~243
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.
| Name | Type | Req | Description |
|---|---|---|---|
| all | boolean | – | Explicit full list for this view |
| limit | integer | – | – |
| offset | integer | – | – |
| view | string | – | compact (default) or full slot record |
