What's New in v0.18.3

Continues the admin portal polish series with tool visibility indicators, configurable login branding, readable dashboard charts, and fixes for misclassified tools.

Admin UI Improvements

Tool Visibility Icons

  • Eye/EyeOff icons now appear next to every tool in both the Explore tab (connection tree) and the Tool Inventory table on the Overview tab
  • Icons reflect the global tools.allow/tools.deny visibility config — hidden tools are dimmed with an EyeOff indicator so operators can immediately see what LLM clients will and won't see
  • New hidden_tools field in the GET /api/v1/admin/connections response powers this, reusing the existing IsToolVisible glob-matching logic from the middleware layer

Login Screen Branding

  • The login page now fetches the platform name from config and displays it as the heading
  • New unauthenticated endpoint GET /api/v1/admin/public/branding returns name and portal_title from server config
  • Falls back to "MCP Data Platform" when the endpoint is unavailable or config is unset
  • Public routes (/api/v1/admin/public/*) bypass auth middleware entirely

Dashboard Bar Charts

  • Completely rewrote BreakdownBarChart — the YAxis width is now computed dynamically from the actual label lengths in each dataset
  • No more truncation: labels like trino_describe_table and datahub_get_entity render in full
  • Email addresses in the Top Users chart are shortened to the local part (e.g. marcus.johnson) with the full address visible on hover via tooltip
  • Eliminated the fixed 80px left margin that was wasting space

Backend Changes

Audit User Breakdown Shows Emails

  • The GET /api/v1/admin/audit/metrics/breakdown?group_by=user_id query now returns COALESCE(NULLIF(user_email, ''), user_id) as the dimension
  • Users with recorded emails display as their email address; users without fall back to user_id
  • Eliminates raw UUIDs from the Top Users dashboard chart

Toolkit Tool List Fixes

  • DataHub: Added datahub_get_column_lineage to the adapter's Tools() return list — it was registered on the MCP server by upstream RegisterAll() but missing from the adapter, causing it to appear as "platform built-in" in the admin UI
  • S3: When read_only: true, the adapter now calls Register(s, ReadTools()...) instead of RegisterAll(), preventing write tools (s3_copy_object, s3_delete_object, s3_put_object) from being registered on the MCP server at all — previously they were registered but excluded from Tools(), causing the same misclassification

Exported IsToolVisible

  • Renamed isToolVisible → IsToolVisible in pkg/middleware/mcp_visibility.go so the admin handler can reuse the same glob-matching logic without duplication

Changelog

Bug Fixes

  • fix: admin UI — visibility icons, login branding, chart labels, toolkit tools (#98)
