Cuba Memorys (LeandroPG19) MCP Server
cuba-memorys
npm
v0.24.0
Published by leandropg19 — 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.
Persistent memory MCP server (v0.15) — 29 tools, PostgreSQL + pgvector, bitemporal facts, BM25+RRF hybrid search, graph metrics/communities, Hebbian learning, episodic memory, audit log, project scoping, tree-sitter codegraph.
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 − 1.2 = 99. What the published surface and source actually contain:
| Points | What was found | Category |
|---|---|---|
| −1.2 | Package runs install-time scripts MTC-SUP-010 | supply-chain |
2. Client adoption risk — 99 − 7 = 92. 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 |
Capability observations and info notes are shown under Findings but never scored.

Findings 4
high Shell/command execution in server code (npm/bin.js)MTC-SRC-002
In the server's implementation (`npm/bin.js:2`): 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: ecFileSync } = require("child_process"); const path = require("path"); const fs = require("fs"); const { ensureBinary }
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 npm/bin.js
low Shell/command execution in packaging/dev tooling (scripts/gen-eval-dataset.py)MTC-SRC-002
In a packaging/dev/install script (shipped, but not the server runtime) (`scripts/gen-eval-dataset.py:51`): 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: "" try: p = subprocess.run( ["claude", "--model", MODEL, "--print", "--output-format", "json"],

low Shell/command execution in packaging/dev tooling (scripts/mcp_live_session_test.py)MTC-SRC-002
In a packaging/dev/install script (shipped, but not the server runtime) (`scripts/mcp_live_session_test.py:81`): 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.

Location: server scripts/mcp_live_session_test.py
low Package runs install-time scripts (postinstall)MTC-SUP-010
"cuba-memorys" executes postinstall script(s) at install time. An install hook runs at install time; most are routine build/setup, but review what it does before trusting it.
Evidence: node npm/postinstall.js
Fix: Review the scripts; install with --ignore-scripts where possible and vet what they do.

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 7
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.

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.
