Is superlocalmemory safe to use?

superlocalmemory scores 92/100 (grade A) on the Canopii Trust Index — strong posture. It passes 17 of the 21 security controls that apply to it, with no confirmed security failures.

How reliable is the security score for superlocalmemory?

We could evaluate 98% of the controls that apply to superlocalmemory. Scores are deterministic — the same source always produces the same score — and a partially-scannable server cannot present a high one, because confidence caps the result. The scanner is open source, so this score can be reproduced independently.

How was superlocalmemory scored?

Its published source was scanned against a fixed catalog of weighted security controls covering code safety, committed secrets, dependency vulnerabilities, tool-description integrity, authentication and transport, and maintenance. A confirmed flaw caps the score outright regardless of what else passes. The full rubric is published.

Security controlslatest scored version vmain@a5438ee

Each control is evaluated deterministically with evidence. The score is earned from passing controls; a failed guard caps it.

Model–MCP Runtime Guardrails

Pass
Indirect Prompt Injection (IPI) Defensesguardno injection markers
Tool/prompt/resource text is free of hidden instructions that could hijack the agent.
Pass
Strict JSON Schema EnforcementadditionalProperties:false present
Tool inputs are constrained (additionalProperties:false), so unexpected arguments can't be smuggled in.
Pass
Tool Definition Integrityguardtool definitions stable; no risky changes in version history
Every consecutive version pair is diffed for new injection markers or destructive scope — a risky diff anywhere in history is a rug-pull (fail, durable); benign description drift warns.
Pass
User-in-the-Loop / Approval Scopeguardno destructive tool scope
No over-broad or destructive tools (arbitrary shell, bulk-delete) that warrant human approval.

Application Security Checks

Warn
No path traversalguard16 occurrences
Naive path checks let tools read/write outside intended directories (EscapeRoute-class).
ide/hooks/post-recall-hook.js:35scripts/__tests__/build-plugin.test.mjs:275scripts/build-copilot-plugin.mjs:92scripts/build-plugin.mjs:610
Fix: Resolve to a canonical path and verify containment; reject ../ and symlinks.
Warn
No SSRF sinksguard9 occurrences
Fetching tool-supplied URLs can pivot into internal networks and metadata services.
scripts/dogfood_savings.py:266scripts/dogfood_savings.py:277scripts/release_registry_guard.py:41src/superlocalmemory/cli/daemon.py:263
Fix: Allow-list destinations; reject arbitrary/loopback/link-local URLs.
Pass
No command-injection sinksguardno sinks found
Untrusted tool input reaching a shell yields remote code execution.
Pass
No dynamic code executionguardno sinks found
eval()/exec()/Function() on tool-derived strings allows arbitrary code execution.
Pass
No unsafe deserializationguardno sinks found
pickle/yaml.load/etc. on untrusted data can execute code.
Pass
No committed secretsguardno secrets found
Hardcoded keys/tokens in published source are live credentials an attacker can use.
Pass
Credentials sourced from environmentreads credentials from environment
Reading secrets from env/secret stores avoids hardcoding them.
Pass
No known-vulnerable dependencies23 runtime deps, no known CVEs
Runtime dependencies (parsed from the lockfile) are scanned against OSV.dev for published CVEs. Advisory: flagged dependencies lower the score but don't hard-cap it, since transitive reachability is unproven.
Pass
Dependencies pinned (lockfile)lockfile present
A lockfile makes installs reproducible and resistant to silent dependency swaps.
Pass
Actively maintainedrecent commits
Unmaintained servers don't receive security fixes.
Pass
Repository not archivedguardactive
Archived repositories will never be patched.
Pass
Declares a licenseAGPL-3.0
A clear license is required for legal enterprise use.
Pass
Has a security policySECURITY.md present
A SECURITY.md gives a private path to report vulnerabilities.
Pass
Adoption & popularityestablished adoption
A small, capped nudge from stars/downloads — widely-used servers get more eyes on bugs. It can never offset a real security failure.
Not checked
Signed releasesnot evaluated
Signed releases let consumers verify artifacts weren't tampered with.
N/A
No install/post-install scriptsguardno published package
install hooks run arbitrary code on every consumer at install time.
N/A
Package name not typosquattingguardno published package
Names mimicking popular packages are a common malware delivery vector.
N/A
Published with provenanceno published package
Build provenance attests the artifact was built from the claimed source by CI.
N/A
Established maintainerno published package
Brand-new / single anonymous maintainers raise takeover and malware risk.

Transport & Trust Model

Warn
Execution Sandboxingruns natively (no container image)
A container/sandbox image limits blast radius; a server that runs natively has full host access.
Fix: Ship a Dockerfile/Containerfile (or document a sandboxed run) so the server runs isolated.
Pass
Network Exposureno bind-all detected
Binding 0.0.0.0 or exposing debug inspectors widens the attack surface.
N/A
Transport Encryption (TLS)guardno remote endpoints
Plaintext HTTP exposes traffic and bearer tokens to interception.
N/A
IAM / Authentication Scopingno remote endpoints
OAuth 2.1 / Protected Resource Metadata gates who can invoke tools.
N/A
Live Endpoint Reachablenot dynamically scanned
A dynamic scan connected to the declared remote endpoint and it responded — verified live, not a dead URL.
N/A
Authentication Enforced (live)not dynamically scanned
If the server declares auth is required, it must actually reject anonymous clients. Serving tools to unauthenticated callers is a real exposure.
