Tested npm @ui5/mcp-server 0.3.3 (Apache-2.0; repo UI5/mcp-server, the UI5 team's GitHub org). Stdio, 10 tools, no key. Real calls: get_guidelines, get_version_info (OpenUI5) and run_manifest_validation on a small local manifest (correctly reported it invalid) all returned results. create_ui5_app, create_integration_card and run_ui5_linter can write files and were not called. Not labelled Official: we did not record a vendor-site page naming the package this run.
Tool-call test (2026-11-11, direct MCP stdio client, no LLM): pass. 3 of 3 read calls passed. App/card creation and linter (can write files) not called. Evidence: local test run, Nov 11, 2026.

Transport (tested 2026-11-11): stdio

Token cost (estimate): approx. 2119 tokens, cl100k estimate (10 tools, measured 2026-11-11, version 0.3.3). This is an estimate from our testing of the tool names, descriptions and input schemas, counted with cl100k_base.

What we tested and what we didn't

Tested on 2026-11-11

  • Install from the registry
  • We connected with no credentials and asked for its tool list: it listed 10 tools (Method details: MCP initialize then tools/list)
  • Maintenance signals (last push, archived/deprecated status)
  • Docs (README length, install and config example)
  • License (OSI-approved or not)
  • Token cost (estimate)

Not tested

  • Security: not audited (no code review, no permission or data-flow analysis)
  • Real tasks (no functional task runs yet)
  • Behaviour with real credentials or a real account
  • Performance, rate limits or load
  • Correctness of results beyond the listed tasks

Methodology: how we test. A high score means it installs and responds, not that giving it access to your data carries no risk.
