Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (14)

`deploy_prototype`	Register a prototype for sharing and get a share URL. Reviewers can leave inline comments via the Marmo overlay.
`generate_component`	Validate and optionally save a custom component for the authenticated tenant. Runs review_generated_code validation before persisting. Use for AI-generated or customized components.
`get_agent_connect_config`	Returns ready-to-paste MCP configuration for Cursor, Claude Code, or Codex. Use on the Connect page or when setting up a new project.
`get_component_info`	Get exact props (with types and defaults), code examples, composition patterns, and common mistakes for a single @marmoui/ui component. REQUIRED before using any component for the first time in a session — prevents hallucinated props (e.g. variant="danger" on Badge, size="lg" on Text) that fail at build time.
`get_design_guidelines`	MANDATORY FIRST CALL before writing any @marmoui/ui code in this session. Returns a step-by-step generation checklist (which tools to call, in what order), critical rules (no namespace sub-components, PageSection is self-closing, no Sidebar export), component patterns, and ICON LIBRARY RULES. Pass iconLibrary (default "phosphor"; also "material" \| "lucide" \| "tabler" \| "heroicons" \| "feather") to get that library's import source, icon name map, and weight/style mapping — and pass the SAME value to review_generated_code so it enforces it. Ask the user which icon library they want before writing UI code. Call topic="patterns" to get the generation checklist specifically.
`get_design_md`	Generate a portable DESIGN.md for the authenticated tenant — brand color, type, tokens, and component inventory — that any AI agent can read to generate on-brand UI. Pass format="markdown" (default) for the DESIGN.md string or format="json" for structured data. Output is deterministic for a given tenant.
`get_knowledge_version`	Returns the MCP knowledge version: gitSha, indexedAt, componentCount, patternCount, uptimeSeconds. Call this ONCE per session before generating UI code so you know how fresh the design-system data is. Cheap to call. If gitSha is "unknown" or indexedAt is far in the past, surface that to the user before relying on the data.
`get_pattern`	Get a complete, validated composition example for a common UI pattern. Available: app-layouts (ASK USER which of 4 layout ids before any full page), app-shell, confirmation-dialog, dialogs-for-other-actions, data-table-with-filters, form-with-validation, posthog-tracking. Call app-layouts first for full pages — returns layout selection flow + AppLayout usage. Pass iconLibrary (default "phosphor") so the usage note tells you which icon import source to rewrite the pattern's icons to. Returns code + inline validation report. Call with no arguments to list all patterns.
`get_prototype_feedback`	Fetch inline comments from a shared prototype as structured data and Markdown. Pull into Cursor/Claude to iterate on feedback.
`get_tenant_theme`	Returns the authenticated tenant's customized theme tokens, CSS variables export, and component overrides. Call after auth to apply tenant-specific styling in generated code.
`list_components`	List all available @marmoui/ui components with names, descriptions, categories, and prop counts. Use to discover what exists. Prefer `search_components` when you already know the use case (form, table, dialog, etc.).
`review_generated_code`	⚠️ MANDATORY — call this on every piece of code you generate before returning it to the user. Validates TSX/JSX against real @marmoui/ui prop signatures and returns { valid, errors[], warnings[], suggestedFixes[], iconLibrary }. Catches: (1) unknown imports, (2) Tabs.List/Tabs.Trigger namespace misuse → auto-suggests TabsList/TabsTrigger fix, (3) PageSection used as wrapper (must be self-closing), (4) hallucinated props, (5) icons imported from the wrong icon library (pass iconLibrary — default "phosphor" — matching what you passed to get_design_guidelines; wrong-library icon imports are ERRORS). If valid=false, fix all errors and call this again. DO NOT return code with errors to the user.
`search_components`	Search @marmoui/ui by keyword (e.g. "form", "table", "dialog", "avatar"). Preferred discovery tool — returns the 5-8 most relevant components for a need. Call this before `get_component_info` when unsure which component to use.
`validate_component_usage`	Validate a TSX/JSX snippet against real @marmoui/ui prop signatures. Returns `{valid, issues[]}`. Prefer `review_generated_code` for post-generation review (it also auto-fixes namespace patterns and suggests related patterns). Use this tool when validating user-provided or existing code rather than newly generated code.
