M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
21/21 tools missing one or more hints — register_session_context (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); sync_project_assets (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); upload_project_asset (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +18 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool test coverage
Only 3/21 tools referenced in tests (14%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
4 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
