## 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 2026-08-04.

- **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 9 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**: 70/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1360 tokens (~151/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 90/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 67% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (9)

### `check_ground_motion` (~315 tokens)

Measured ground motion (sinking/uplift) for a US address or lat/lon, in mm/year AND in/year, from NASA OPERA Sentinel-1 InSAR. Costs $0.40 from your SibFly credits; out-of-coverage / too-stale / too-low-confidence / fuzzy-geocode return FREE. Use the gate params to avoid paying for data you'd reject. dry_run=true is a FREE coverage+cost preview.

Input parameters:

- `address` (string): US street address
- `compact` (boolean): lean payload (fewer tokens)
- `dry_run` (boolean): FREE preview: coverage + would_cost + data age, no rate, no charge
- `explain` (boolean): add ground_brief: ~600 tokens of plain-English narration + FAQ (engine GL52 free tier / CL46 paying). Adds ~10s latency. Only set when a human will read the output; use ask_inspector for follow-up Q&…
- `lat` (number)
- `lon` (number)
- `max_age_days` (integer): if data older than this, return free instead of billing
- `min_confidence` (number): 0-1; below this, return free instead of billing
- `require_significant` (boolean): if the rate would be no_clear_trend (within its error bar), return FREE instead of billing — never pay for statistical noise
- `since` (string): YYYY-MM-DD; if no new data since this date, return free

Output parameters:

- `assessment_code` (string|null)
- `confidence` (number|null)
- `cost_usd` (number)
- `credits_remaining_usd` (number|null)
- `data_age_days` (integer|null)
- `engine` (string|null): narration engine: GL52 (free tier) or CL46 (paying)
- `ground_brief` (string|null): only when explain=true
- `near_threshold` (boolean|null)
- `status` (string)
- `velocity_uncertainty_mm_yr` (number|null)
- `velocity_vertical_in_yr` (number|null)
- `velocity_vertical_mm_yr` (number|null)

### `check_portfolio` (~126 tokens)

Batch ground-motion for many US addresses in one call. Only covered addresses are billed ($0.40 each); misses and duplicate cells are free. If credits run out mid-batch the response status is 'insufficient_credits' and unbilled items are marked — top up (buy_credits) and retry them.

Input parameters:

- `addresses` (array, required): up to 1000 US addresses (must be an ARRAY, not one string)
- `max_spend_usd` (number): hard budget cap: billing stops at this total; over-budget items come back skipped_for_budget

Output parameters:

- `credits_remaining_usd` (number|null)
- `results` (array)
- `status` (string)
- `summary` (object)

### `get_coverage` (~115 tokens)

FREE pre-flight: is a US address/point covered, how stale is the data (data_age_days), and what a report would cost. Accepts ONE address/lat+lon, OR addresses[] (up to 1000, needs your Bearer key) to size a whole job before spending. Call this before spending.

Input parameters:

- `address` (string)
- `addresses` (array): batch mode: size a whole job in one free call
- `lat` (number)
- `lon` (number)

Output parameters:

- `covered` (boolean)
- `data_age_days` (integer|null)
- `frame` (string|null)
- `results` (array|null)
- `summary` (object|null)
- `would_cost_usd` (number|null)

### `get_motion_history` (~157 tokens)

Multi-year cumulative motion history for an address. Pass from_date and to_date (YYYY-MM-DD) to get the movement between two dates. Costs $0.40 (misses free). dry_run=true is a FREE preview (points + dates + cost, no data); max_age_days returns free instead of billing for stale data.

Input parameters:

- `address` (string)
- `dry_run` (boolean): FREE preview: coverage + n_points + would_cost, no series, no charge
- `from_date` (string)
- `lat` (number)
- `lon` (number)
- `max_age_days` (integer): if data older than this, return free instead of billing
- `to_date` (string)

Output parameters:

Output parameters:

- `credits_usd` (number)
- `price_per_report_usd` (number)
- `reports_remaining_est` (integer)
- `top_up_url` (string)

### `register_agent` (~106 tokens)

FREE: create a new SibFly account and get an API key + free starter credits in ONE call — no human, no captcha, no card. Use this when you have no API key. SAVE the returned api_key and pass it as the Bearer token on later calls (MCP clients: set it as the Authorization header).

Input parameters:

- `email` (string, required): a durable email address (disposable domains rejected)
- `password` (string): optional; auto-generated and returned if omitted

Output parameters:

- `api_key` (string)
- `credits_usd` (number)
- `password` (string)
- `price_per_report_usd` (number)
- `reports_remaining` (integer)

### `buy_credits` (~97 tokens)

Get a machine-usable payment link to top up credits (requires your Bearer API key). method 'stripe' returns a card checkout_url; 'crypto' returns a BTC invoice_url + txn_id. Open/relay the URL to complete payment; credits land automatically afterwards — confirm with get_account.

Input parameters:

- `amount_usd` (number, required): 1 to 10000 (USD)
- `method` (string): default stripe (card)

Output parameters:

- `question` (string, required): your question about the report

Output parameters:

- `reply` (string)

- `count` (integer)
- `items` (array)
- `spent_today_usd` (number)
