## 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.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 84 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 342 tokens (~114/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

### 2026-07-27 (score 46)

First indexed and scored.

## MCP tools (3)

### `doi_score_lookup` (~123 tokens)

Fetch a Depth-of-Identity score for a Nostr pubkey from the PowForge oracle. Returns either an L402 challenge (macaroon + bolt11 invoice + price_sats) for the caller to pay, or a Schnorr-signed score envelope when paid auth is supplied. Pricing is 1-2 sats per call.

Input parameters:

- `auth` (object): L402 paid auth. Omit on first call to receive the challenge.
- `pubkey` (string, required): 64-hex Nostr pubkey or npub1... bech32 string

### `doi_sign_vouch` (~122 tokens)

Build an UNSIGNED kind:33335 PowForge vouch event template. The MCP server intentionally never holds keys — the caller signs externally and publishes the signed event to relays.

Input parameters:

- `content` (string): Optional human-readable note
- `depth` (number, required): Voucher's claimed DoI depth (integer)
- `sats` (number): Optional sats backing
- `target` (string, required): 64-hex pubkey of the subject being vouched
- `vouch_count` (number, required): Voucher's total outbound vouch count (drives sqrt dilution)

### `doi_score_verify` (~97 tokens)

Locally verify a Schnorr-signed DoI score envelope returned by the PowForge oracle. No network call. Default oracle pubkey is hardcoded; override via oracle_pubkey or the ORACLE_PUBKEY env var.

Input parameters:

- `envelope` (object, required): The full signed JSON from a prior doi_score_lookup
- `oracle_pubkey` (string): Override oracle pubkey (64-hex). Default = b4b12d...
