Midas Memory MCP Server
midas-memory
PyPI
v1.0.0
Published by vornicx — 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.
Local-first, eval-first memory for long-horizon AI agents — no LLM at ingest
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 − 0 = 100. What the published surface and source actually contain:
The deterministic scan raised no scored threat in the surface it inspected — the threat score stayed at 100. Capability observations and advisory notes are recorded but never lower it.
2. Client adoption risk — 100 − 7 = 93. 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 7
high Dynamic evaluation of a non-literal value (eval/memory_safety.py)MTC-SRC-010
In the server's implementation (`eval/memory_safety.py:239`): Evaluating a runtime value as code (rather than a fixed literal) executes whatever reaches it — a direct RCE primitive, and almost never necessary in legitimate code. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: t(f"\n=== Memory-safety eval ({attacks} attacks, {benign} benign) ===") print(f"ASR (attack-success, want 0.00)
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 eval/memory_safety.py
high Dynamic code execution in server code (eval/coding_bench.py)MTC-SRC-001
In the server's implementation (`eval/coding_bench.py:4`): Evaluating strings as code is the most direct RCE primitive; if any tool input reaches it, the server executes attacker-chosen code. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: ) and the Memory-Safety eval (`eval/memory_safety.py`): decision_currency a revised architecture decision surfaces
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 (midas/cli.py)MTC-SRC-002
In the server's implementation (`midas/cli.py:132`): 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: rce and remove: subprocess.run(remove, capture_output=True, text=True) # best-effort; ignore if not present

high Shell/command execution in server code (midas/mcp_server.py)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.

medium Dynamic module load from a non-literal (packages/midas-ts/src/embeddings.ts)MTC-SRC-005
In the server's implementation (`packages/midas-ts/src/embeddings.ts:93`): Loading a module chosen at runtime (from a variable) can pull in and run attacker-influenced code paths. This is read from the code itself — not from the tool description — so a poisoned server cannot hide it behind honest-looking metadata.
Evidence: transformers = await import(spec); } catch { throw new Error( "semantic embeddings need the optiona

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

What this scan could not see
- Tools were statically extracted from the published source (17 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Versions 1
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 |
|---|---|---|---|---|
v1.0.0 latest |
A 93/100 | 7 | 1.13.0 | 2026-08-25 |
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.
