+28 this week 78 Trust /100
Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →

Supply Chain Security83
  • No malware found by supply-chain analysis.Pass
  • CVE check failed: a known medium-severity CVE affects @hono/node-server 1.19.17, reached via @modelcontextprotocol/sdk > @hono/node-server. A fixed version is available. View diagnostics → Fail
  • No install/post-install scripts declared.Pass
  • Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency97
  • Source repository is publicly reachable at the declared URL. View diagnostics → Pass
  • Cryptographically verified build provenance (signed, bound to UI5/webcomponents-react). View diagnostics → Pass
  • Clear OSI-approved license (Apache-2.0).Pass
  • Actively maintained (last published 3 days ago).Pass
  • Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability74
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 1825 tokens (~304/item across 6 items; 5 tools + 1 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 Management27
  • Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (20% of tools); any adoption earns full credit.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

WHEN TO USE: The user wants to create a new app, project, or starter using UI5 Web Components for React. WORKFLOW: Call this tool to get the template setup instructions, then execute them.

get_component_api ~767

Get comprehensive API documentation for a UI5 Web Components React component including props, ref methods, types, event detail parameters, and CSS parts for shadow DOM styling. WHEN TO USE: You need exact prop names, types, default values, method signatures, event detail fields, or CSS part selectors for a specific component. DO NOT USE FOR: General guidance on styling, events, or architecture — use get_documentation instead. To discover component names — use list_components first.

Returns all props and methods for that component. EXAMPLE INPUT: { "componentName": "Dialog" } **Output Format (JSON):** ```typescript { package: string, // NPM package name description: string, // Full JSDoc description with @tags, examples, notes props: { [propName: string]: { type: { name: string, // Type category (e.g., "string", "boolean", "enum") raw?: string, // Full TypeScript type string value?: Array<{ // For enums: possible values with descriptions value: string, description?: string }> }, required: boolean, // Whether prop is required defaultValue: any, // Default value if specified description: string, // Full prop description with notes eventDetail?: { // Present on event handler props (web components only) params: Array<{ // Fields available on e.detail name: string, // e.g., "targetRef", "escPressed", "item" type: string, // e.g., "HTMLElement", "boolean" description: string // What this detail field contains }>, cancelable: boolean, // true = e.preventDefault() prevent…

WHEN TO USE: You need guidance on how to use the library — setup, styling, event handling, SSR, slots, i18n. DO NOT USE FOR: Looking up specific component props or methods — use get_component_api instead. For public utilities/hooks from @ui5/webcomponents-react-base — use get_public_utils.
