Hot Memory MCP Server
hot-memory-mcp
PyPI
v0.8.0
Published by michael-denyer — no publish provenance, so origin is unverified, but the source is public: the repository link below is self-declared yet readable, so you can inspect the code before adopting it.
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 |
|---|---|---|
| −33 | Hardcoded AWS access key id in server code ×2 MTC-SRC-008 | exfiltration |
| −2.1 | Package has no source repository MTC-SUP-011 | supply-chain |
2. Client adoption risk — 65 − 7 = 58. 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 |
| −1 | publisher verification (public source) — no provenance, but the source is public and inspectable |
| ✓ | inspection depth (source) — how much of the target the scan could see |
Grade capped: 2 confirmed high findings → grade capped at D. A hard gate overrides the point total — no amount of clean surface buys back a confirmed catastrophe.
Capability observations and info notes are shown under Findings but never scored.

Findings 8
high Hardcoded AWS access key id in server code (tests/test_mining.py)MTC-SRC-008
A live-looking AWS access key id is hardcoded in `tests/test_mining.py:1306`. 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 tests/test_mining.py
high Hardcoded GitHub token in server code (tests/test_storage.py)MTC-SRC-008
A live-looking GitHub token is hardcoded in `tests/test_storage.py:196`. Secrets in source ship to everyone who installs the package and are a direct credential leak.
Evidence: GitHub token: ghp_…(redacted)
Fix: Remove the secret, rotate it, and load credentials from the environment or a secret store.
Location: server tests/test_storage.py
high Shell/command execution in server code (src/memory_mcp/cli.py)MTC-SRC-002
In the server's implementation (`src/memory_mcp/cli.py:209`): 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: subprocess.run(
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 src/memory_mcp/cli.py
high Shell/command execution in server code (src/memory_mcp/project.py)MTC-SRC-002
In the server's implementation (`src/memory_mcp/project.py:32`): 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.

high Shell/command execution in server code (tests/test_hook.py)MTC-SRC-002

low Package has no source repositoryMTC-SUP-011
"hot-memory-mcp" declares no repository URL, so its published artifact cannot be compared against reviewable source.
Fix: Prefer packages that link to public, reviewable source.
Location: package hot-memory-mcp
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 |
|---|---|---|---|---|
v0.8.0 latest |
D 65/100 | 8 | 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.
