Claude Connectors Directory readiness

✅ Every tool has a title 33 of 33 tools
✅ Every tool declares readOnlyHint or destructiveHint 33 of 33 tools
✅ Tool names are 64 characters or fewer All within limit
❌ Descriptions avoid instructions about model behavior or other tools 4 of 33 descriptions reference other tools or tell the model what it must do: browser_network_request, browser_take_screenshot, browser_session_open, browser_session_close
✅ No hidden instructions or invisible characters in tool metadata None found

Checks the directory's published tool requirements that are visible from tools/list. Passing them does not guarantee acceptance.

What this server's tools can do

Makes outbound web requests: browser_navigate, browser_navigate_back, browser_network_request
Has delete or destructive operations: browser_drop

Not a vulnerability by itself. It tells you what an injected prompt could ask this server to do, so you can decide which tools need approval.
