Available components
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. How we score → Why this is hard to score →
Supply Chain Security98
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- 31 of 95 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass

- Clear OSI-approved license (Apache-2.0).Pass
- Actively maintained (last published 72 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability80
- AI-judged instruction clarity (excellent).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management93
- Stability observed for 28 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the io.github.kakunin-ai/kakunin MCP server?

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
audit_log_append ~184
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.
| Name | Type | Req | Description |
|---|---|---|---|
| event_type | string | yes | 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 | yes | 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. |
No output schema declared.
No examples provided.
check_risk_score ~56
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
verify_agent_scope ~175
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.
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | yes | 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"). |
