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 |
|---|---|---|
| −15.4 | Untrusted input concatenated into a command sink ×10 MTC-SRC-009 | injection |
| −14.2 | Unsafe deserialization ×8 MTC-SRC-007 | permissions |
| −6.3 | Package runs install-time scripts MTC-SUP-010 | supply-chain |
Capability observations and info notes are shown under Findings but never scored.

Findings 33
high Reads a sensitive credential path or dumps the environment (dist/tools/rangeConfig.js)MTC-SRC-006
In the server's implementation (`dist/tools/rangeConfig.js:15`): Reading private keys / cloud credentials, or serializing the whole environment, is a sensitive-data source that becomes exfiltration when combined with any egress. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: ~/.ssh
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.

medium Hardcoded egress to an external endpoint (dist/utils/downloadSchemas.js)MTC-SRC-003
In the server's implementation (`dist/utils/downloadSchemas.js:129`): A hardcoded outbound call to a fixed external host inside server code is a classic exfiltration/telemetry channel — especially paired with reads of local data.

"@iflow-mcp/ludus-mcp" executes postinstall script(s) at install time. The large majority of malicious packages abuse install hooks to run code before you ever import them.

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 |
|---|---|---|---|---|
v1.0.24 latest |
D 64/100 | 33 | 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.
