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.

Undici has Unhandled Exception in WebSocket Client Due to Invalid server_max_window_bits Validation
Undici has Unbounded Memory Consumption in WebSocket permessage-deflate Decompression

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
7/7 tools missing one or more hints — get_matches (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_match (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); derive_odds (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 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
6/7 tool handlers declare input schemas (86%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
5/7 tool handlers wrap calls in try/catch (71%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 0/7 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
5 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 4 high severity in production deps — undici@6.21.0 (high), undici@6.21.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
