🚨

Reads files from sensitive locations

Touches: /etc/nexus-chatgpt-remote.env

🔐

You'll be asked for 5 credentials: NEXUS_MCP_BEARER_TOKEN, NEXUS_WEB_COUNCIL_TOKEN, NEXUS_V3_ADMIN_KEY, NEXUS_CHATGPT_API_KEY, NEXUS_V5_SSH_KEY

These are read from process.env at runtime. Make sure you trust where they’ll be sent.

glob_workspace

Find workspace files by glob pattern without invoking a shell.

terminate_workspace_process

To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.

// quality suggestions

Tool annotations

17/28 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

11/28 tools missing one or more hints — self_test (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_devices (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_device (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +8 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.

License file

No license file

Add a LICENSE file (MIT, Apache-2.0, etc.).

Tool test coverage

17/28 tools referenced in tests (61%)

Write tests that reference each tool by name so every tool has at least one test.

No access to sensitive paths

Reads sensitive paths: /etc/nexus-chatgpt-remote.env

Remove reads of sensitive system paths. If you genuinely need them, document why in the README.

Secrets not logged

1 secret value sent to print

Redact or omit secret values from log output.

// full audit trail

The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.

// improvement guidance — verified publishers only

We have 6 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
