    How to connect

    How to connect flowpack to Claude

    The server address to paste into Claude settings:

    https://flowpack-mcp.flowpackplugin.workers.dev/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Server tool list (5)

    Raw names from tools/list. Only developers need these.

    browseUniversal catalog reader. Routes by domain ('kits', 'presets', 'palettes', 'seasonal', 'settings', 'decorations', 'effects', 'diagnostics', 'anatomy', 'compatibility') with optional facet filter (e.g., 'button.hover') and free-text query. Returns paged items with id/name/description and metadata-only marker. Use this for ANY merchant question about 'what options are available' or 'show me X'.
    planMASTER KEY tool. Analyzes natural-language merchant intent ('make my buttons feel premium', 'wellness brand vibe', 'BFCM aggressive') and returns a structured plan of settings to change across Flowpack's Button + Cart + Badge + Variant + Frosty Pill kits. Handles single tweaks (one hover style) and full overhauls (50+ settings) with the same call. Returns opaque plan_id, change count, preview URL, and reasoning. ALWAYS call preview() before execute().
    explainNatural-language explanation of a plan_id (what it does) or setting_path (what one setting controls). Audience: merchant (default), developer, or reviewer. Detail: brief (1-2 sentences) or deep (full context + related settings + a11y notes). Use when merchant asks 'what does this do' or 'why this preset'.
    recommendGoal-oriented recommendation engine. Scenarios: 'personalized_4_plans' (returns 4 diverse plans — safe / aspirational / seasonal / conversion-tested), 'preset_for_brand', 'color_palette_for_theme', 'touch_target_for_devices', 'motion_density_for_audience', 'seasonal_for_calendar', 'diagnostics_first_check'. Use for proactive suggestions when merchant intent is unclear.
    diagnoseRuntime + theme + settings harmony check. Free-text symptom (e.g., 'cart drawer feels slow', 'badges not appearing') OR kit-scoped check. Returns categorized issues (theme_compat / settings_conflict / runtime_error / a11y / performance) with severity and optional fix_plan_id callable via execute(). health_score 0-100.
