## 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 (95 of 99), 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 (95 of 99), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 71/100
  - Repository check failed: the declared repository URL redirects; it must resolve directly.
  - Cryptographically verified build provenance (signed, bound to nqzai/kakunin-mcp).
  - Clear OSI-approved license (Apache-2.0).
  - Actively maintained (last published 25 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 415 tokens (~138/item across 3 items; 3 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 (3)

### `verify_agent_scope` (~175 tokens)

Check whether this agent is authorised to perform a specific action or call a specific endpoint. Verifies the active X.509 certificate, permitted_actions scope, financial limits, and revocation status. Call this BEFORE executing any action that might exceed scope — not after.

Input parameters:

- `action` (string, required): The action or endpoint the agent wants to perform. Can be a scope string (e.g. "write:invoices"), an API path (e.g. "/api/v1/execute_trade"), or a plain description (e.g. "initiate EUR/USD trade on e…
- `amount_usd` (number): Optional transaction amount in USD for financial scope enforcement.
- `venue` (string): Optional trading venue or system being accessed (e.g. "euronext", "xetra").

### `check_risk_score` (~56 tokens)

Retrieve this agent's rolling 30-day risk score, risk band (low/medium/high), and drift trend. Returns actionable guidance — use this to decide whether to self-throttle, escalate to a human, or proceed normally.

### `audit_log_append` (~184 tokens)

Append a behavioral event to this agent's immutable audit log. Use this to voluntarily record actions — transactions, data operations, API calls. Returns the risk score for the event and a transaction ID for traceability. High-risk events (score >= 0.85) automatically trigger a certificate revocation check.

Input parameters:

- `event_type` (string, required): Type of behavioral event being logged. Use "transaction_initiated" for financial operations, "data_mutation" for write/delete ops, "api_call" for standard API calls.
- `metadata` (object, required): Arbitrary key-value pairs describing the event. For transactions: include amount, currency, venue. For data ops: include resource_type, resource_id, operation. Avoid PII — this is stored in the immut…
- `session_id` (string): Optional session ID for grouping related events in the audit trail.
