Network Monitor MCP Server
Provides network monitoring capabilities including real-time latency measurement, ping sweeps, and subnet scanning via MCP tools, with a companion web dashboard for live visualization.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
get_network_statusGet current network status: reachability and round-trip latency to the gateway and an internet host (default 8.8.8.8), plus whether the connection is online.
ping_devicePing a single host (IP address or hostname) once and return whether it is alive and its round-trip time in milliseconds.
scan_networkScan the local /24 subnet (default 192.168.18.0/24) by ping-sweeping every host, then enrich responders with MAC address and vendor from the ARP cache. Returns the list of active devices.
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
3/3 tools missing one or more hints — get_network_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ping_device (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); scan_network (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). 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.
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.
Production dependencies are patched
0 critical, 4 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (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.
