### FEATURE - Using preview-middleware with cds-launchpad-plugin

_As a **Developer**,
I want to use the `preview-middleware` to show the UI5 apps in a launchpad,
so that I can see all UI5 Apps in a automatically created FLP._
### Description


In my CAP projects, i use [`cap-launchpad-plugin`](https://github.com/geert-janklaps/cds-launchpad-plugin) to create a FLP with all UI5 Applications i defined in the CAP Project, without create manually a FLP html page.
A similar approach like [`preview-middleware`](https://github.com/SAP/open-ux-tools/tree/main/

### [fiori-mcp-server] DXT extension crashes silently in Claude Desktop after initialize (Electron-bundled Node incompatibility)

## Summary
When `@sap-ux/fiori-mcp-server` is installed as a Claude Desktop `.dxt` extension, the server process is spawned by Claude Desktop's built-in (Electron-embedded) Node runtime. The server starts, accepts the JSON-RPC `initialize` message, then exits silently ~300–700 ms later with no stderr output. Claude Desktop logs only:

```
Server transport closed unexpectedly, this is likely due to the process exiting early.
```

Running the same `dist/index.js` against a real Node v25.8.2 (or an

### Add MCP tool annotations to fiori-mcp-server

## Summary

The `@sap-ux/fiori-mcp-server` package is missing [MCP tool annotations](https://modelcontextprotocol.io/specification/2025-03-26/server/tools#annotations) on its tool definitions. Tool annotations help AI assistants understand tool behavior and make better decisions about when and how to use them.

## Current State

In `packages/fiori-mcp-server/src/tools/index.ts`, the tools are defined without annotations:

```typescript
export const tools = [
    {
        name: 'search_docs',

### BUG - ⚠ Large MCP response (~25.1k tokens), this can fill up context quickly

markdown# `search_docs` tool returns excessively large responses that quickly consume context window

## Description

When using the `search_docs` tool from the fiori-mcp server, responses can be extremely large (25k+ tokens), which rapidly fills the context window and impacts the effectiveness of the MCP integration.

## Steps to Reproduce

1. Use the `search_docs` tool with a specific query
2. Observe the token count in the response
3. Note how quickly the context window fills with subsequent

### BUG - fiori-mcp `download_odata_service_metadata`: clarify `appPath` pre-condition to prevent LLMs from passing a non-existent folder

### Related Feature

Feature request: _N/A — this is a bug report on the existing `download_odata_service_metadata` tool exposed by `@sap-ux/fiori-mcp-server`._

### Description

The MCP tool `download_odata_service_metadata` (exposed by `@sap-ux/fiori-mcp-server`) requires its `appPath` parameter to point to an **already-existing** directory into which `metadata.xml` will be written. This pre-condition is not documented in the tool's input schema description, so LLMs consuming the MCP ser

### [fiori-mcp-server] CLI help/version flags print no output

## Summary

The published `@sap-ux/fiori-mcp-server` binary silently ignores top-level CLI information flags.

`fiori-mcp --help`, `fiori-mcp --version`, and an invalid flag all exit with status 0 and print no stdout/stderr. This makes it hard for users and MCP client setup scripts to verify the installed version, discover usage, or detect a typo before configuring the server.

## Reproduction

Tested on Windows with Node.js 24.16.0 and `@sap-ux/fiori-mcp-server@1.0.3`.

```powershell

### FEATURE - Wrap `fetch-service-metadata` errors in the structured response shape

`generate-fiori-ui-application`'s handler wraps its body in try/catch and returns a structured `status: "Error"`. `fetch-service-metadata` doesn't, so any inner throw (typically a missing entry in `@sap-ux/store`) bubbles into the MCP framework's generic error wrapper and the actual message never reaches the caller. Small consistency fix; big DX win for first-time and non-VS-Code users.

### Technical Design

Wrap the `executeFunctionality` body of `fetch-service-metadata` in try/catch and mirro

### BUG - Missing dependency declaration (Fiori MCP Server)

### Description
I tried out the "Fiori MCP Server" and it is really great and cool to use. But I discovered the following issue:

If you add the MCP server to Claude Code via `claude mcp add fiori --transport stdio -- npx -y @sap-ux/fiori-mcp-server@0.6.47 fiori-mcp`, Claude Code is not able to start the MCP server and connect to it.
After some debugging the issue was, that the dependency `apache-arrow` (https://www.npmjs.com/package/apache-arrow) is required on my machine, which is not defined
