## 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**: 86/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (94 of 98), 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 (94 of 98), 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 133 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 68/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 673 tokens (~134/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**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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.

## 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 67, +1)

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (5)

### `hash` (~175 tokens)

Hash text using MD5, SHA-1, SHA-256, SHA-512, or HMAC. Can also compare two hash values or compute all hash algorithms at once.

Input parameters:

- `action` (string, required): Action to perform: hash (single algorithm), hmac (keyed hash), compare (compare two hashes), hash_all (all algorithms at once)
- `algorithm` (string): Hash algorithm (for hash and hmac actions). Default: sha256
- `encoding` (string): Output encoding. Default: hex
- `hash1` (string): First hash (for compare action)
- `hash2` (string): Second hash (for compare action)
- `key` (string): Secret key (for hmac action)
- `text` (string): Text to hash (for hash, hmac, hash_all actions)

### `encode_decode` (~67 tokens)

Encode or decode text using Base64, URL encoding, HTML entities, hex, or binary. Can also auto-detect the encoding format of input.

Input parameters:

- `action` (string, required): Encoding/decoding action to perform
- `text` (string, required): Text to encode, decode, or detect

- `symbols` (boolean): Include symbols. Default: true
- `uppercase` (boolean): Include uppercase letters. Default: true

### `jwt` (~116 tokens)

Decode JWT tokens to inspect header and payload, check expiry status, or create unsigned JWTs for testing purposes. Not for production authentication.
