Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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
28/28 tools missing one or more hints — authenticate_youtube (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_music_videos (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create_playlist (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +25 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.
Descriptions match behaviour
7 tools describe read intent but their handlers mutate — get_playlist_items (line 245: /^P(?:(\d+)D)?T?(?:(\d+)H)?(?:(\d+)M)?(?:(\d+)S)?$/.exec(iso)); get_video_details (line 245: /^P(?:(\d+)D)?T?(?:(\d+)H)?(?:(\d+)M)?(?:(\d+)S)?$/.exec(iso)); get_liked_videos (line 245: /^P(?:(\d+)D)?T?(?:(\d+)H)?(?:(\d+)M)?(?:(\d+)S)?$/.exec(iso))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
15/28 tool handlers declare input schemas (54%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
26/28 tool handlers wrap calls in try/catch (93%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
10 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets never reach shell commands
1 secret value passed to shell commands — possible command injection
Never pass secrets through shell commands. Use library APIs that accept credentials as arguments.
Secrets not logged
7 secret values sent to console.log
Redact or omit secret values from log output.
Production dependencies are patched
0 critical, 1 high severity in production deps — @modelcontextprotocol/sdk@1.0.4 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Tool description accuracy
4 tools have description/behavior mismatches: get_playlist_items: description implies read-only but handler writes/deletes/executes; search_channel_videos: description implies read-only but handler writes/deletes/executes; get_channel_latest_videos: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
