Driftlock MCP Server
driftlock

v3.3.3
Published by an unidentified publisher — no publish provenance and no public repository, so the publisher could not be verified and the source cannot be independently located.
The grade answers one question — how safe is this server for you to adopt — so it is computed in two auditable stages. Nothing below is an opinion or an LLM's guess; every line is a real term the deterministic engine applied, and the same input always yields the same number.
1. Threat score — 100 − 35.1 = 65. What the published surface and source actually contain:
| Points | What was found | Category |
|---|---|---|
| −22 | Hardcoded AWS access key id in server code MTC-SRC-008 | exfiltration |
| −11 | Untrusted input concatenated into a command sink ×3 MTC-SRC-009 | injection |
| −2.1 | Package has no source repository MTC-SUP-011 | supply-chain |
2. Client adoption risk — 65 − 11 = 54. Three small, subtract-only factors that reflect your risk in adopting it — a clean scan proves less on a powerful, unverified or barely-inspectable package, so the grade says so plainly:
| Points | Adoption-risk factor |
|---|---|
| −6 | capability blast radius (high) — client exposure if the model is manipulated |
| −5 | publisher verification (none) — trust in the source of the package |
| ✓ | inspection depth (source) — how much of the target the scan could see |
Grade capped: 1 confirmed high finding → grade capped at C. A hard gate overrides the point total — no amount of clean surface buys back a confirmed catastrophe.

Findings 10
high Hardcoded AWS access key id in server code (test/e2e.js)MTC-SRC-008
A live-looking AWS access key id is hardcoded in `test/e2e.js:124`. Secrets in source ship to everyone who installs the package and are a direct credential leak.
Evidence: AWS access key id: AKIA…(redacted)
Fix: Remove the secret, rotate it, and load credentials from the environment or a secret store.
Location: server test/e2e.js
high Shell/command execution in server code (bin/driftlock.js)MTC-SRC-002
In the server's implementation (`bin/driftlock.js:16`): 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 bin/driftlock.js
high Shell/command execution in server code (src/diff.js)MTC-SRC-002
In the server's implementation (`src/diff.js:12`): 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.

high Shell/command execution in server code (src/git.js)MTC-SRC-002
In the server's implementation (`src/git.js:18`): 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

high Shell/command execution in server code (test/e2e.js)MTC-SRC-002

This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

medium Untrusted input concatenated into a command sink (bin/driftlock.js)MTC-SRC-009
In the server's implementation (`bin/driftlock.js:131`): A shell/process command assembled from concatenated or interpolated values is command injection when any part is attacker-influenced — the OWASP canonical RCE flow. Verify what reaches the interpolated value. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.

low Package has no source repositoryMTC-SUP-011
"driftlock" declares no repository URL, so its published artifact cannot be compared against reviewable source.
Fix: Prefer packages that link to public, 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 |
|---|---|---|---|---|
v3.3.3 latest |
D 65/100 | 10 | 1.5.0 | 2026-07-23 |
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.
