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:
| Points | What was found | Category |
|---|---|---|
| −28.5 | Obfuscated / encoded payload in server code ×4 MTC-SRC-004 | injection |
Capability observations and info notes are shown under Findings but never scored.

Findings 7
high Obfuscated / encoded payload in server code (dist/index.js)MTC-SRC-004
In the server's implementation (`dist/index.js:2`): Decoding an encoded blob and executing it is how malicious logic is hidden from human review of the source. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: \x20\x20\x20\x20\x20\x20\x20\x20
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/index.js
high Obfuscated / encoded payload in server code (dist/templates/ioc.js)MTC-SRC-004
In the server's implementation (`dist/templates/ioc.js:1`): Decoding an encoded blob and executing it is how malicious logic is hidden from human review of the source. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

high Obfuscated / encoded payload in server code (dist/templates/vue2.js)MTC-SRC-004
In the server's implementation (`dist/templates/vue2.js:1`): Decoding an encoded blob and executing it is how malicious logic is hidden from human review of the source. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: \x20\x20\x20\x20\x20\x20\x20\x20

high Obfuscated / encoded payload in server code (dist/templates/vue3.js)MTC-SRC-004
In the server's implementation (`dist/templates/vue3.js:1`): Decoding an encoded blob and executing it is how malicious logic is hidden from human review of the source. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: \x20\x20\x20\x20\x20\x20\x20\x20\x20\x20

Location: server dist/templates/vue3.js
high Shell/command execution in server code (dist/cli/ioc.js)MTC-SRC-002
In the server's implementation (`dist/cli/ioc.js:2`): 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/cli/ioc.js

medium Dynamic module load from a non-literal (dist/cli/ioc.js)MTC-SRC-005
In the server's implementation (`dist/cli/ioc.js:2`): 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: import(_0x313088)
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/cli/ioc.js
What this scan could not see
- No tools were enumerated, so prompt-injection, capability and toxic-flow analysis had no tool surface to inspect. To grade a package’s real runtime tools, scan the running server: --command "npx -y <package>".
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.
| Version | Score | Findings | Engine | Scanned |
|---|---|---|---|---|
v1.0.35 latest |
C 72/100 | 7 | 1.5.0 | 2026-07-22 |
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.
Verify this score yourself
The score above is reproducible: the same package version always yields the same result. Run it locally or over the free API — no account, no LLM, fully deterministic.
