## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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)

  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 62/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 842 tokens (~280/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.

## MCP tools (3)

### `sibfly_ground_motion` (~338 tokens)

Satellite-measured GROUND MOTION for a US address — is the land under a property SINKING or rising (subsidence / uplift / heave), in mm/year and in/year, from NASA Sentinel-1 InSAR. Use for property foundation risk, land subsidence, sinkhole/settlement concern, real-estate due diligence, or "is this address sinking?". Returns vertical velocity (mm/yr + in/yr) with uncertainty, seasonal amplitude, total motion, a plain-language assessment, confidence, and provenance. With a SibFly key (_apiKey) this is a full paid report ($0.40 from your credits); without a key it returns a FREE teaser (coverage + confidence + would_cost_usd). Out-of-coverage addresses return coverage:false and are never billed.

Input parameters:

- `_apiKey` (string): Optional SibFly API key (Bearer). With a key you get the full paid report; without one you get a free coverage/confidence teaser. Free key: POST https://sibfly.com/api/v1/autonomous/register.
- `address` (string): US street address, e.g. "1600 Pennsylvania Ave NW, Washington DC". Provide this OR lat+lon.
- `brief` (boolean): If true, add a short plain-English narration of the result.
- `include_timeseries` (boolean): If true, embed the full motion history (per-date measurements) in the same report.
- `lat` (number): Latitude (WGS84). Use with lon instead of address.
- `lon` (number): Longitude (WGS84). Use with lat instead of address.

### `sibfly_coverage` (~192 tokens)

FREE preflight: does SibFly have satellite ground-motion coverage for this US address, and what would a full report cost? No key required. Returns coverage (true/false), confidence, and would_cost_usd. Use this before sibfly_ground_motion to check a property is covered without spending credits.

Input parameters:

- `_apiKey` (string): Optional SibFly API key (Bearer). With a key you get the full paid report; without one you get a free coverage/confidence teaser. Free key: POST https://sibfly.com/api/v1/autonomous/register.
- `address` (string): US street address, e.g. "1600 Pennsylvania Ave NW, Washington DC". Provide this OR lat+lon.
- `lat` (number): Latitude (WGS84). Use with lon instead of address.
- `lon` (number): Longitude (WGS84). Use with lat instead of address.

### `sibfly_timeseries` (~259 tokens)

Historical ground-motion time series for a US address — the per-date satellite measurements of vertical displacement over time (how the land has moved, month by month). Use to see the TREND of subsidence/uplift, not just the current velocity. series_type "measured" = real per-pass observations (premium frames); "modeled" = fitted trend on real acquisition dates. Needs a SibFly key for the full series ($0.40); keyless returns a coverage teaser.

Input parameters:

- `_apiKey` (string): Optional SibFly API key (Bearer). With a key you get the full paid report; without one you get a free coverage/confidence teaser. Free key: POST https://sibfly.com/api/v1/autonomous/register.
- `address` (string): US street address, e.g. "1600 Pennsylvania Ave NW, Washington DC". Provide this OR lat+lon.
- `lat` (number): Latitude (WGS84). Use with lon instead of address.
- `lon` (number): Longitude (WGS84). Use with lat instead of address.
- `series_type` (string): "measured" (real per-pass observations) or "modeled" (fitted trend). Default measured.

## Common questions

### What is the Sibfly MCP server?

Sibfly is an MCP server listed in the public MCP registry as io.github.pipeworx-io/sibfly. SibFly, satellite-measured ground motion (subsidence / uplift) for any US address. This page covers its npm package (@pipeworx/mcp-sibfly).

### Is the Sibfly MCP server safe to use?

Sibfly scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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 Sibfly MCP server expose?

Sibfly exposes 3 tools: sibfly_ground_motion, sibfly_coverage, sibfly_timeseries. Their descriptions and schemas cost roughly 789 tokens of context every time the server is loaded.

### Is the Sibfly MCP server still maintained?

Sibfly is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Sibfly MCP server under?

Sibfly declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
