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.
Multer vulnerable to Denial of Service via deeply nested field names
nanoid: non-secure generators can loop indefinitely with negative size
Multer vulnerable to Denial of Service via incomplete cleanup of aborted uploads

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
50/50 tools missing one or more hints — register_session (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); reply_message (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); wait_message (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +47 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 inputs are validated
Only 15/50 tool handlers declare input schemas (30%)
Declare an inputSchema with zod/joi/yup on every tool definition.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
38/50 tools referenced in tests (76%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
11 child_process/subprocess calls in production code — runs shell commands (src/rr/cursor-agent-launcher.ts:41, src/rr/cursor-agent-orphans.ts:13, src/rr/cursor-spawn.ts:49)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets stay with their owner
2 secret/sensitive values flow into network calls (POLARPRIVATE_PORT → dynamic, POLARPRIVATE_PORT → dynamic)
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
Production dependencies are patched
0 critical, 2 high severity in production deps — multer@2.1.1 (high), nanoid@5.1.7 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

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.
