v1.0.5
Published by cyanheads — no publish provenance and no vendor-owned scope, so the publisher could not be verified. The repository link below is self-declared.
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 |
|---|---|---|
| −9.5 | Unsafe deserialization ×2 MTC-SRC-007 | permissions |
Capability observations and info notes are shown under Findings but never scored.

Findings 2
medium Unsafe deserialization (dist/mcp-server/tools/workflowInstructionsGetter/logic.js)MTC-SRC-007
In the server's implementation (`dist/mcp-server/tools/workflowInstructionsGetter/logic.js:55`): Deserializing untrusted data with these APIs can execute arbitrary code (a well-known RCE gadget class). This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: yaml.load(
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/mcp-server/tools/workflowInstructionsGetter/logic.js
medium Unsafe deserialization (dist/services/workflow-indexer/WorkflowIndexService.js)MTC-SRC-007
In the server's implementation (`dist/services/workflow-indexer/WorkflowIndexService.js:66`): Deserializing untrusted data with these APIs can execute arbitrary code (a well-known RCE gadget class).

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 |
|---|---|---|---|---|
v1.0.5 latest |
A 91/100 | 2 | 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.
