Owner: ztaylor
Last live-state check: 2026-06-18 (dashboard 200; gateway zeb-gateway-test live)
Fixtures used: gateway zeb-gateway-test (7 main-catalog tools, Arcade-Headers auth); users A/B from config/targets.yaml. Raw evidence in tests/probes.md.

Log

2026-06-18 — lib client connects live; protocol/curation/per-user-visibility/ungranted probes done.
- PASS: protocol compliance (connect/list/invoke/structured error), tool curation (7 listed == 7 selected).
- FINDING: per-user tool list scoping not differentiated via Arcade-Headers on one gateway (A==B). Needs cat-3 Contextual Access or separate gateways / User Source.
- Q5: ungranted tool → McpError: tool not enabled for this gateway.

2.2 — connect a second real MCP client (Claude Code) to the gateway (no-adapter evidence).
2.5 — dynamic registration: add/remove a tool on the gateway (dashboard or API), re-list, confirm no restart. (needs a gateway edit)
2.7 — mixed prebuilt + custom: compose a gateway with a main tool + a lib/mcp_server tool. (needs reference server → arcade login/arcade deploy)
2.4 — whoami execution proof that calls run as the calling user. (needs reference server)
2.8 — finalize scores once the above land.
