## 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)

Scored 2026-08-03.

- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (96 of 100), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (96 of 100), so this covers what we could see, not the whole tree.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 70, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (23)

### `create_signing_session` (~431 tokens)

Create signing session

⚠️ This performs a consequential, possibly irreversible action (legally-binding signature request and/or quota consumption). Confirm with the human before calling. Create a single-signer "express" signing (or action-authentication) session and return its IDs plus a ready-to-share `signingUrl` (url + embed token). Consumes signature quota.

Input parameters:

- `action` (object): What is being authenticated — used when purpose=ACTION_AUTHENTICATION.
- `cancelUrl` (string): Redirect URL if the signer cancels.
- `customSteps` (array): Ordered step types — REQUIRED only when policyProfile=CUSTOM (e.g. ["CLICKWRAP","OTP"]).
