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 |
|---|---|---|
| −23.1 | Dynamic evaluation of a non-literal value ×2 MTC-SRC-010 | injection |
Capability observations and info notes are shown under Findings but never scored.

Findings 9
high Dynamic evaluation of a non-literal value (chrome-extension/entrypoints/background/record-replay/actions/handlers/extract.ts)MTC-SRC-010
In the server's implementation (`chrome-extension/entrypoints/background/record-replay/actions/handlers/extract.ts:93`): Evaluating a runtime value as code (rather than a fixed literal) executes whatever reaches it — a direct RCE primitive, and almost never necessary in legitimate 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: new 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.

high Dynamic evaluation of a non-literal value (chrome-extension/entrypoints/background/record-replay/actions/handlers/script.ts)MTC-SRC-010

high Dynamic code execution in server code (chrome-extension/entrypoints/background/record-replay/actions/handlers/extract.ts)MTC-SRC-001
In the server's implementation (`chrome-extension/entrypoints/background/record-replay/actions/handlers/extract.ts:93`): 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.

medium Dynamic module load from a non-literal (chrome-extension/utils/simd-math-engine.ts)MTC-SRC-005

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 |
|---|---|---|---|---|
v1.1.1 latest |
C 77/100 | 9 | 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.
