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 | Dynamic evaluation of a non-literal value ×4 MTC-SRC-010 | injection |
| −15.4 | Obfuscated / encoded payload in server code MTC-SRC-004 | injection |
| −11 | Unsafe deserialization ×3 MTC-SRC-007 | permissions |
| −2.1 | Package has no source repository MTC-SUP-011 | supply-chain |

Findings 25
high Reads a sensitive credential path or dumps the environment (venv_win/Lib/site-packages/aiohttp/client.py)MTC-SRC-006
In the server's implementation (`venv_win/Lib/site-packages/aiohttp/client.py:1446`): 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: .netrc
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.

low Package has no source repositoryMTC-SUP-011
"mcp-edge-tts" declares no repository URL, so its published artifact cannot be compared against reviewable source.

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 |
|---|---|---|---|---|
v0.1.1 latest |
F 43/100 | 25 | 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.
