A Why this grade 100 − 2.1 = 98/100

Every server starts at 100. These are the exact deductions the deterministic engine applied — each one reproducible, none of it an opinion or an LLM's guess:

Findings 7

high Dynamic code execution in server code (dist/normalizeUrl-BrUSzVK4.js)MTC-SRC-001

In the server's implementation (`dist/normalizeUrl-BrUSzVK4.js:1`): Evaluating strings as code is the most direct RCE primitive; if any tool input reaches it, the server executes attacker-chosen code. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

Evidence: Function(`

Fix: Review this call path: confirm it never receives unsanitized tool input, constrain it, or remove it. Treat a server whose code reaches these sinks as high-capability regardless of what its tools claim.

Location: server dist/normalizeUrl-BrUSzVK4.js

high Dynamic code execution in server code (dist/stdio-DoN2tUts.js)MTC-SRC-001

In the server's implementation (`dist/stdio-DoN2tUts.js:12`): Evaluating strings as code is the most direct RCE primitive; if any tool input reaches it, the server executes attacker-chosen code. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

Evidence: Function(`

Fix: Review this call path: confirm it never receives unsanitized tool input, constrain it, or remove it. Treat a server whose code reaches these sinks as high-capability regardless of what its tools claim.

Location: server dist/stdio-DoN2tUts.js

high Shell/command execution in server code (dist/main-DJa7796U.js)MTC-SRC-002

In the server's implementation (`dist/main-DJa7796U.js:1`): Spawning a shell/process is command-execution capability; with unsanitized tool input it is command injection / RCE. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

Evidence: child_process

Fix: Review this call path: confirm it never receives unsanitized tool input, constrain it, or remove it. Treat a server whose code reaches these sinks as high-capability regardless of what its tools claim.

Location: server dist/main-DJa7796U.js

high Shell/command execution in server code (dist/secretstore-B7UBzLo4.js)MTC-SRC-002

In the server's implementation (`dist/secretstore-B7UBzLo4.js:1`): Spawning a shell/process is command-execution capability; with unsanitized tool input it is command injection / RCE. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

high Shell/command execution in server code (dist/transportDetection-BgA9FQsV.js)MTC-SRC-002

In the server's implementation (`dist/transportDetection-BgA9FQsV.js:1`): Spawning a shell/process is command-execution capability; with unsanitized tool input it is command injection / RCE. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

Location: server dist/transportDetection-BgA9FQsV.js

medium Dynamic module load from a non-literal (dist/helpers-BrpBfS5F.js)MTC-SRC-005

In the server's implementation (`dist/helpers-BrpBfS5F.js:30`): Loading a module chosen at runtime (from a variable) can pull in and run attacker-influenced code paths. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

Evidence: require(t)

Fix: Review this call path: confirm it never receives unsanitized tool input, constrain it, or remove it. Treat a server whose code reaches these sinks as high-capability regardless of what its tools claim.

Location: server dist/helpers-BrpBfS5F.js

low Package has no source repositoryMTC-SUP-011

"@onyxsecurity/mcp-gateway" declares no repository URL, so its published artifact cannot be compared against reviewable source.

Fix: Prefer packages that link to public, reviewable source.

Location: package @onyxsecurity/mcp-gateway

Versions

Scan history per published version. The engine is deterministic — the same version always yields the same score, so a changed score means the package itself changed.

Embed this score

Show this server's live Trust Score in your README, docs or website. The badge is served straight from the registry and updates automatically after every rescan — no API key needed. It links back to this page, so anyone who sees the grade can also read the findings behind it instead of taking a number on faith.
