Tools & capabilities
Kakunin MCP tools 3
verify_agent_scopeCheck whether this agent is authorised to perform an action before executing it. Verifies the active X.509 certificate, permitted_actions scope, financial limits, and revocation status.check_risk_scoreRetrieve the agent's rolling 30-day risk score, band (`low`/`medium`/`high`), drift trend, and actionable guidance. No input required.audit_log_appendAppend a behavioral event to the agent's immutable audit log. Returns risk score + transaction ID. Events scoring ≥ 0.85 auto-trigger a certificate revocation check.
MCP Server Scf tools 196
scf_list_controlsList SCF security controls from the reference catalog. Returns paginated controls with SCF ID, title, description, and mapped frameworks. Filter by domain, framework, or free-text search.scf_get_controlGet a single SCF control by ID. Returns description, mapped frameworks, assessment objectives, and linked evidence items from the reference catalog.scf_list_frameworksList every compliance framework mapped in the SCF catalog (NIST 800-53, ISO 27001, SOC 2, FedRAMP, GDPR, and 350+ more). Returns framework identifiers and display names.scf_list_domainsList every compliance domain in the SCF taxonomy. Domains group related controls (e.g., GOV = Governance, AST = Asset Management, IAC = Identity & Access Control).scf_list_evidence_catalogList evidence items from the SCF reference catalog — the 272 standard evidence types that can be collected to demonstrate control implementation. Supports free-text search and pagination.scf_list_assessment_objectivesList SCF assessment objectives — the 5,736 test criteria used to evaluate control implementation. Optionally filter by control ID; supports free-text search and pagination.scf_get_domainGet one SCF domain with its controls (read, no org). Deprecated controls are excluded unless include_deprecated is set; a deprecated domain still resolves, badged.scf_get_catalog_evidenceGet one catalog evidence entry with the controls it maps to (read, no org). The reference definition, not an organization's tracking record — see scf_get_evidence for that.scf_list_scoped_controlsList controls scoped to the organization with implementation status. Filter by scope status, domain, framework, CSF function, weighting, or free-text search. Paginated.scf_get_scoped_controlGet one scoped control in detail: owner, implementation notes, evidence links, and audit history. Identify by scf_id, not by UUID.scf_update_scoped_controlUpdate a scoped control's implementation fields (write — editor+ role). Identify by scf_id, not UUID. Only provided fields are applied.scf_get_scoping_statsGet the organization's implementation statistics: counts by status, overall completion percentage, and per-framework coverage breakdown.- +184 more on the listing page
