KINOCUT_MCPB_PYTHONMCP_VIDEO_CRUSH_PATHKINOCUT_C2PATOOLMCP_VIDEO_C2PATOOLANTHROPIC_API_KEYTool annotations
9/392 tools have annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
383/392 tools missing one or more hints — video_filter (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); video_filter (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); video_luma_key (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +380 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.
Destructive tools are labelled
2 tools perform destructive updates without destructiveHint — video_cleanup deletes at line 612 (os.remove(p)); video_cleanup deletes at line 612 (os.remove(p))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Tool test coverage
186/392 tools referenced in tests (47%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
3 child_process/subprocess calls in production code — runs shell commands (mcpb/server/launcher.js:65, mcpb/server/native-launcher.js:84, npm/bin/kinocut.js:6)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
