Model–MCP Runtime Guardrails
- FailUser-in-the-Loop / Approval Scopeguard1 over-broad tool(s)
No over-broad or destructive tools (arbitrary shell, bulk-delete) that warrant human approval. How many servers fail this?
systemFix: Scope tools narrowly; avoid arbitrary command execution and destructive defaults.
- PassIndirect Prompt Injection (IPI) Defensesguardno injection markers
Tool/prompt/resource text is free of hidden instructions that could hijack the agent.
- PassStrict JSON Schema EnforcementadditionalProperties:false present
Tool inputs are constrained (additionalProperties:false), so unexpected arguments can't be smuggled in.
- N/ATool Definition Integrityguardno prior version to diff
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.
Application Security Checks
- FailNo install/post-install scriptsguardruns postinstall
install hooks run arbitrary code on every consumer at install time. How many servers fail this?
Fix: Remove preinstall/install/postinstall scripts, or document and minimize them.
- WarnDependencies pinned (lockfile)no lockfile found
A lockfile makes installs reproducible and resistant to silent dependency swaps.
Fix: Commit a lockfile (package-lock.json / pnpm-lock.yaml / poetry.lock).
- WarnPublished with provenanceno provenance attestation
Build provenance attests the artifact was built from the claimed source by CI.
Fix: Publish with npm provenance (--provenance) from a trusted CI.
- WarnEstablished maintainersingle maintainer
Brand-new / single anonymous maintainers raise takeover and malware risk.
Fix: Publish under an established account/org; add multiple maintainers.
- PassNo command-injection sinksguardno sinks found
Untrusted tool input reaching a shell yields remote code execution.
- PassNo dynamic code executionguardno sinks found
eval()/exec()/Function() on tool-derived strings allows arbitrary code execution.
- PassNo path traversalguardno sinks found
Naive path checks let tools read/write outside intended directories (EscapeRoute-class).
- PassNo SSRF sinksguardno sinks found
Fetching tool-supplied URLs can pivot into internal networks and metadata services.
- PassNo unsafe deserializationguardno sinks found
pickle/yaml.load/etc. on untrusted data can execute code.
- PassNo committed secretsguardno secrets found
Hardcoded keys/tokens in published source are live credentials an attacker can use.
- PassCredentials sourced from environmentreads credentials from environment
Reading secrets from env/secret stores avoids hardcoding them.
- PassNo known-vulnerable dependencies1 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.
- PassPackage name not typosquattingguarddistinct package name
Names mimicking popular packages are a common malware delivery vector.
- PassActively maintainedrecent commits
Unmaintained servers don't receive security fixes.
- PassRepository not archivedguardactive
Archived repositories will never be patched.
- PassDeclares a licenseMIT
A clear license is required for legal enterprise use.
- PassHas a security policySECURITY.md present
A SECURITY.md gives a private path to report vulnerabilities.
- PassAdoption & 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 checkedSigned releasesnot evaluated
Signed releases let consumers verify artifacts weren't tampered with.
Transport & Trust Model
- WarnExecution 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.
- PassNetwork Exposureno bind-all detected
Binding 0.0.0.0 or exposing debug inspectors widens the attack surface.
- N/ATransport Encryption (TLS)guardno remote endpoints
Plaintext HTTP exposes traffic and bearer tokens to interception.
- N/AIAM / Authentication Scopingno remote endpoints
OAuth 2.1 / Protected Resource Metadata gates who can invoke tools.
- N/ALive Endpoint Reachablenot dynamically scanned
A dynamic scan connected to the declared remote endpoint and it responded — verified live, not a dead URL.
- N/AAuthentication 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.
