Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 14 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability77
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1747 tokens (~124/item across 14 items; 14 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 Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage99
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 96% of tool parameters carry a description.Partial
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "deploy_prototype" implies "deploy" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 14 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.mahmoudilyan/marmo-ui MCP server?
io.github.mahmoudilyan/marmo-ui is a hosted endpoint at https://mcp.marmoui.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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 →
deploy_prototype ~70
Register a prototype for sharing and get a share URL. Reviewers can leave inline comments via the Marmo overlay.
| Name | Type | Req | Description |
|---|---|---|---|
| deployUrl | string | – | Deployed URL if already live |
| prototypeId | string | yes | Unique prototype identifier (slug) |
| title | string | – | Human-readable prototype title |
No output schema declared.
No examples provided.
generate_component ~101
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.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | Generated TSX code using @marmoui/ui primitives |
| componentName | string | yes | PascalCase component name, e.g. CustomStatCard |
| description | string | yes | What the component should do |
| save | boolean | – | Save as tenant component override if validation passes |
No output schema declared.
No examples provided.
get_agent_connect_config ~57
Returns ready-to-paste MCP configuration for Cursor, Claude Code, or Codex. Use on the Connect page or when setting up a new project.
| Name | Type | Req | Description |
|---|---|---|---|
| client | string | – | Target agent client. Omit to get all configs. |
No output schema declared.
No examples provided.
get_component_info ~106
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.
| Name | Type | Req | Description |
|---|---|---|---|
| componentName | string | yes | Name of the component to get information about (e.g. "Button", "Card", "Input") |
No output schema declared.
No examples provided.
get_design_guidelines ~250
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.
| Name | Type | Req | Description |
|---|---|---|---|
| iconLibrary | string | – | Icon library the agent should import from. Default: "phosphor". Ask the user which library they want before writing UI code; if they have no preference, omit this and the default (Phosphor) applies.… |
| topic | string | – | Specific guideline topic (default: "all") |
No output schema declared.
No examples provided.
get_design_md ~97
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.
| Name | Type | Req | Description |
|---|---|---|---|
| format | string | – | Output format. "markdown" returns the DESIGN.md string; "json" returns structured data. |
No output schema declared.
No examples provided.
get_knowledge_version ~83
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_pattern ~231
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.
| Name | Type | Req | Description |
|---|---|---|---|
| iconLibrary | string | – | Icon library the caller is using. Default: "phosphor". The returned usage note tells the agent which icon import source to use, and the inline validation enforces it. Supported: phosphor, material, l… |
| patternId | string | – | Pattern identifier, e.g. "app-shell", "data-table-with-filters", "confirmation-dialog", "dialogs-for-other-actions". Omit to list all available patterns. |
No output schema declared.

get_prototype_feedback ~57
Fetch inline comments from a shared prototype as structured data and Markdown. Pull into Cursor/Claude to iterate on feedback.
| Name | Type | Req | Description |
|---|---|---|---|
| includeResolved | boolean | – | – |
| prototypeId | string | yes | Prototype ID/slug to fetch feedback for |
No output schema declared.
No examples provided.
get_tenant_theme ~39
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_components ~93
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.).
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Filter by category (e.g., "Components", "Layout") |
| status | string | – | Filter by status (e.g., "stable", "beta") |
No output schema declared.
No examples provided.
review_generated_code ~307
⚠️ 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.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | The complete TSX/JSX code you just generated. Must import from @marmoui/ui. |
| context | string | – | Optional: describe what the code is supposed to do (e.g. "settings page with tabs"). Helps produce more targeted feedback. |
| iconLibrary | string | – | Icon library the code must import icons from. Default: "phosphor". Pass the SAME value you passed to get_design_guidelines. When set, imports from any other icon library are reported as ERRORS. Suppo… |
No output schema declared.
No examples provided.
search_components ~102
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | number | – | Maximum results to return (default: 10) |
| query | string | yes | Search query — matches against component names, descriptions, categories, and prop names |
No output schema declared.
No examples provided.
validate_component_usage ~154
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.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | TSX/JSX code snippet to validate against @marmoui/ui |
| iconLibrary | string | – | Optional: icon library the code must import icons from. Default: "phosphor". When set, imports from any other icon library are reported as errors. Supported: phosphor, material, lucide, tabler, heroi… |
