Tools & capabilities

Melta UI tools 6

  • get_tokenGet a design token by dot-path. Returns the token object with its value and class mapping.
  • get_componentGet component metadata including variants, sizes, accessibility requirements, HTML sample, per-state specs (stateSpecs: disabled/loading/open/empty etc. — each with delta class strings + aria changes), and anatomy parts (overlay/container/th etc. with element/roles/class). Prefer these structured fields over inferring states from the HTML sample.
  • check_ruleCheck class strings against this design system's prohibition rules. Returns violations with reasons and alternatives.
  • check_htmlLint a full HTML/JSX source against melta-ui rules — the same checks as CI and the PostToolUse hook (class rules + html-attr rules + composition rules for HTML). Use this AFTER generating UI code to self-verify before presenting it. Response always includes coverage info (manual rules cannot be auto-checked).
  • searchSearch across tokens and components by keyword. Matches against names, values, class strings, and descriptions. Returns up to 20 results (truncated flag when more matched).
  • get_rulesGet melta-ui prohibition rules from rules.json (107 total). Use this to retrieve manual/contextual rules that check_rule cannot auto-detect. Supports filtering by category, severity, or detector.

Vectordecisions MCP Server tools 6

  • gatri_trust_scorelegacy composite trust scoring.
  • assure_actionevidence-backed, context-aware assurance for one agent action.
  • decide_actionconverts GATRI assurance + policy + permissions + context into `ALLOW`, `RESTRICT`, `REQUIRE_HUMAN`, or `DENY`.
  • risk_assessmentdeployment risk assessment.
  • compliance_checkEU AI Act-oriented policy check.
