• build_get_examplesA

  SuperoB

  Fetch a COMPLETE, production-quality reference app (schemas.py + config.py + setup.py + ui/app.js) to copy patterns from — the single biggest lever for app quality. archetype='index' (default) lists the available archetypes with per-file byte sizes; pick the one closest to your app ('commerce-marketplace' | 'service-booking' | 'ops-dashboard' | 'multitenant-portal' | 'saas-billing') and fetch it BEFORE authoring your UI. These are real 'stunning' apps; mirror how they compose the SDK components, art-direct the landing page, and structure schemas. Optional file= to fetch just one file ('schemas.py' | 'config.py' | 'setup.py' | 'ui/app.js'). Responses are PAGED (~32KB/section): when the header says more:true, fetch the next section with offset=<next_offset> — never re-fetch from 0.

• loginA

  RhylthymeA

  For apps that cannot connect the Rhylthyme account directly: returns a sign-in URL, then accepts the pasted token. Only the user's own saved programs, runs and imports need it; everything public works without. Tokens last about an hour.

• get_icon_svg_bulkA

  infyicon-mcpA

  Return ready-to-embed SVG markup for 1-20 Infyicon icons in one call (pass an array of ids from search_icons). Use when building a UI, icon set or design system so you fetch several icons at once instead of calling get_icon_svg repeatedly; use get_icon_svg for a single icon. Read-only, no auth; ids beyond the first 20 are silently dropped; each bad or unknown id gets a per-item error while the rest still succeed; oversized SVGs (>200 KB) return svg_url instead of markup. Free with attribution to infyicon.com.

• get_app_videosA

  MagicScreenshotsB

  App Store preview videos for a library app: poster frames for everyone; with a Pro API key, 1-hour download links to the mp4 files (about 30 s each). Use them as reference when making your own app preview video. Pass slug from list_directory_apps (has_video=true finds apps that have them).

• apps_get_shared_keywordsA

  Manifold MCPA

  Store searches that two to twenty apps all rank for, with each app's position side by side. Use when: "where do we and competitor both rank", "which store keywords does Teams beat Slack on", comparing apps keyword by keyword. Not for: every keyword one app ranks for, use apps_get_keywords. Finding the competitors first, use apps_get_competitors. Returns: List. rows[]: keyword, volume, ranks[] (app_id, rank) in the order the apps were given. Sorted by volume. United States and English only. Params: store (required; google_play | app_store), app_ids (required; 2 to 20), limit (100, max 1000), cursor, provider, max_credits, dry_run. Cost: 5 + 5 per 100 rows. Default 100 rows = 10 credits. Cached 7 days. Example: {"store": "google_play", "app_ids": ["com.Slack", "com.microsoft.teams"]}

• render_parcel_shapeA

  PortlandMaps (Unofficial)B

  Render a property's lot as an interactive UI component (inline SVG): a City of Portland aerial photo underlay (showing the true roofline) with the parcel outline, the building footprint(s) on the lot, approximate setback dimensions, a north arrow, and faint neighbouring parcels overlaid on top. Provide a detailType+detailId to fetch geometry, or pass rings directly. Aerial, footprints, and neighbours come from Portland's public ArcGIS layers; set basemap="none" to drop the photo and includeContext=false for just the bare outline. Renders in MCP Apps hosts (Claude) and legacy mcp-ui hosts.

• app-listA

  SupaMarketers DataC

  List the SupaMarketers Apps available to this account (same catalog as the website), with each app's Credits price. Call without slug for a summary list (optionally filter by query); call with slug for one app's full input_schema, which defines the fields app-run expects. Only apps with api_runnable=true can be run via app-run; apps whose forms require file uploads cannot run here.

• review_sceneA

  Showoff.dev – AI Mockup GeneratorA

  Runs the full art-direction review of a project: collisions (frame by frame for films), angles, floating versus resting devices, text overlap, cropping and contrast, composition and color. Use it while building to see every finding, including warnings edit_scene saves anyway; use finish once at the end for the final check, and render_preview to look at the result. Read-only. Every finding has a severity and a fix with ready-to-send edit_scene ops. Returns the findings, errors first, and whether the scene passes.

• check_mcp_appA

  Sigistry Plugin & Skill CatalogA

  Get the Sigistry MCP App safety criteria to audit an MCP App (MCP Apps / SEP-1865: a tool that returns an interactive ui:// HTML resource the host renders in a sandboxed iframe) BEFORE shipping it. Returns two groups of checks: spec conformance (ui:// scheme, the text/html;profile=mcp-app mimeType, tool-to-UI linkage via _meta.ui.resourceUri, a text fallback, visibility values, and CSP coverage of external origins) and security hygiene the iframe sandbox does not cover (unsafe DOM sinks, embedded secrets, host-message origin handling, remote scripts). Call this when the user is building or reviewing an MCP App; then apply each check to the app source you have in context and report findings. Nothing is sent to this server; an interactive browser version is at https://sigistry.com/mcp-app-checker.

• get_building_breakdownA

  Cenogram - Polish Real Estate DataA

  Get the building-by-building breakdown for one transaction: footprint area, number of storeys, and estimated total floor area (footprint × storeys) for each building on the property. search_transactions / search_by_area / search_by_polygon return per-transaction building SUMS inline; this tool splits them into individual buildings. Use it after a search when a result has building data and you need the detail (e.g. a developed-land deed covering several buildings). Each building also carries a construction-age estimate derived from building-permit records. It is an ESTIMATE with an interval, never a registry construction date, and the records only start in 2016 — so for most buildings the honest answer is "construction year not established", which is stated explicitly rather than left out. The transaction_id is the id shown on a search result that has building data. Cost: 4 tokens. Returns nothing for a transaction with no buildings.

  Use this when someone asks which apps they track in AppSkyline, or an app's id is needed. Returns each app's id, name, default locale and its App Store, Mac App Store, Google Play and Microsoft Store ids, up to 100 apps. Not for finding other apps in a store.

• list_componentsA

  ionic-framework-mcpA

  List the UI components of Ionic Framework, optionally filtered by a keyword. Use this to find the component that fits a piece of UI before building it by hand, and to learn the custom element name it is used under. Use limit 100 to list every component. Returns `tag`, `description` and `url` per component, where `url` is the documentation page carrying its full API reference. Do not use this to read a component's API: call `get_doc_page` with the returned `url`. Do not use it for Capacitor plugins or native capabilities, which are covered by the Capacitor MCP server at https://capacitor-mcp.capawesome.io/mcp.

• build_get_skillsA

  SuperoB

  Fetch a Supero build reference. doc='skills' (default, the spec you MUST follow) | 'components' (the real pre-built SDK component/global catalog — read so you don't reinvent UI) | 'rubric' (the rich-app quality checklist — what 'stunning' means) | 'landing' (compact landing-page derivation + quality bar — MANDATORY read for public-facing apps) | 'integrations' (the EXACT services.* wrapper→service_id→args map for email/sms/stripe/ai/etc.) | 'web' / 'transactional' / 'workflows' / 'mobile' / 'services' (deep companion docs) | 'e2e_testing'. Returns the doc + a content version + the SDK floor to pin. Read 'skills' FIRST, then 'components' + a matching build_get_examples before you author UI. Docs are PAGED (~32KB/section): when the header says more:true, fetch the next section with offset=<next_offset> — never re-fetch from 0.
