## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-23.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - 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.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 55/100
  - AI-judged instruction clarity (good).
  - 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.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 85/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 54% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

First indexed and scored.

## MCP tools (5)

### `clarke_list_slots` (~243 tokens)

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.

Input parameters:

- `all` (boolean): Explicit full list for this view
- `limit` (integer)
- `offset` (integer)
- `view` (string): compact (default) or full slot record

### `clarke_get_slot` (~251 tokens)

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.

Input parameters:

- `slug` (string, required): Slot slug, e.g. '19-2e'

### `clarke_get_terminal` (~133 tokens)

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.

Input parameters:

- `slug` (string, required): Slot slug, e.g. '101w'

### `clarke_list_deltas` (~446 tokens)

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.

Input parameters:

- `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'

### `clarke_list_satellites` (~68 tokens)

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

Input parameters:

- `limit` (integer)
- `operator` (string)
- `ownerCountry` (string)

## Common questions

### What is the Clarke GEO registry MCP server?

Clarke GEO registry is an MCP server listed in the public MCP registry as io.github.xentoshi/clarke. Who sits at each GEO longitude, with FCC licences, orbit freshness and disputes. Keyless. This page covers its hosted endpoint (https://www.clarkebelt.finance/api/v1/mcp).

### Is the Clarke GEO registry MCP server safe to use?

Clarke GEO registry scores 62 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Clarke GEO registry MCP server expose?

Clarke GEO registry exposes 5 tools: clarke_list_slots, clarke_get_slot, clarke_get_terminal, clarke_list_deltas, clarke_list_satellites. Their descriptions and schemas cost roughly 1,141 tokens of context every time the server is loaded.

### Does the Clarke GEO registry MCP server require authentication?

No. We connected to Clarke GEO registry without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Clarke GEO registry MCP server still maintained?

Clarke GEO registry is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
