## 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 87 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 76/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 615 tokens (~123/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**: 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.

## MCP tools (5)

### `evermint_mint` (~160 tokens)

Mint a tamper-evident, cryptographically timestamped record of an AI agent action, decision, or observation. Returns a Record ID and SHA-256 hash that can be used to prove what the agent did and when. Use this whenever an agent takes an action that may need to be audited, disputed, or verified later.

Input parameters:

- `action_type` (string, required): Short label for the action being recorded (e.g. transaction_approved, decision_made, data_accessed)
- `agent_id` (string): Identifier for this agent or system
- `payload` (object): The state, decision, or context to preserve. Any JSON object.
- `timestamp` (string): ISO 8601 datetime or 'auto'. Defaults to auto.

### `evermint_verify` (~66 tokens)

Verify an existing EverMint record by Record ID. Confirms the record exists, has not been altered, and returns its metadata. No API key required, verification is public.

Input parameters:

- `record_id` (string, required): The EverMint Record ID to verify (format: EVR-XXXXXXXX)

### `evermint_list_records` (~159 tokens)

List EverMint records belonging to the authenticated account. Supports filtering by agent_id, action_type, and date range. Returns record IDs, action types, timestamps, and agent IDs, not full payloads. Use this when an agent needs to audit its own past actions or build context from prior decisions.

Input parameters:

- `action_type` (string): Filter to a specific action type
- `agent_id` (string): Filter to records minted by a specific agent
- `limit` (number): Max records to return (1-200, default 50)
- `since` (string): ISO 8601: only return records on or after this time
- `until` (string): ISO 8601: only return records on or before this time

### `evermint_get_record` (~86 tokens)

Fetch the full contents of a single EverMint record by Record ID, including the original payload that was minted. Requires authentication and the record must belong to the authenticated org. Use this when an agent needs to retrieve the actual content of a prior decision or action it recorded.

Input parameters:

- `record_id` (string, required): The EverMint Record ID to fetch (format: EVR-XXXXXXXX)

### `evermint_verify_chain` (~144 tokens)

Verify the integrity of a sequence of hash-chained EverMint records. Confirms each record's hash matches its content, and that each record correctly references the prior record in the chain with no gaps or tampering. Use this to prove an entire sequence of agent decisions is intact, not just a single record. This is public, no API key required.

Input parameters:

- `length` (number): Used with start_record_id. Max records to walk (1-100, default 10)
- `record_ids` (array): Ordered list of Record IDs to verify as a chain, oldest first
- `start_record_id` (string): Verify the chain starting from this record forward
