Security controls

Deterministic, evidence-backed. Score 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 Stabilityguardtool definitions stable

    Tool definitions did not change after publish — no post-approval rug-pull.

  • 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 traversalguard39 occurrences

    Naive path checks let tools read/write outside intended directories (EscapeRoute-class).

    scripts/clean-tmp.js:13scripts/rendering-live-scenario.mjs:39scripts/rendering-live-scenario.mjs:94scripts/sync-mcp-plugin.js:36

    Fix: Resolve to a canonical path and verify containment; reject ../ and symlinks.

  • Warn
    No known-vulnerable dependencies1 of 94 runtime deps vulnerable; worst high

    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.

    [email protected] — GHSA-88fw-hqm2-52qc[email protected] — GHSA-j6c9-x7qj-28xf[email protected] — GHSA-rv63-4mwf-qqc2[email protected] — GHSA-wgpf-jwqj-8h8p

    Fix: Upgrade the flagged dependencies past their fixed versions.

  • Warn
    Has a security policyno security policy

    A SECURITY.md gives a private path to report vulnerabilities.

    Fix: Add SECURITY.md with a disclosure contact and process.

  • 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 SSRF sinksguardno sinks found

    Fetching tool-supplied URLs can pivot into internal networks and metadata services.

  • 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
    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 licenseMIT

    A clear license is required for legal enterprise use.

  • 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
    IAM / Authentication Scopingno authentication handling detected

    OAuth 2.1 / Protected Resource Metadata gates who can invoke tools.

    Fix: Implement OAuth 2.1 with a .well-known/oauth-protected-resource document.

  • Warn
    Live Endpoint Reachabledeclared remote unreachable

    A dynamic scan connected to the declared remote endpoint and it responded — verified live, not a dead URL.

    Fix: Ensure the declared remote endpoint is reachable and speaks MCP.

  • Warn
    Network Exposurebinds 0.0.0.0

    Binding 0.0.0.0 or exposing debug inspectors widens the attack surface.

    Fix: Bind to 127.0.0.1 by default; never ship open debug endpoints.

  • Pass
    Transport Encryption (TLS)guardall remotes use HTTPS

    Plaintext HTTP exposes traffic and bearer tokens to interception.

  • Pass
    Execution Sandboxingcontainerized

    A container/sandbox image limits blast radius; a server that runs natively has full host access.

  • N/A
    Authentication Enforced (live)no declared auth to verify

    If the server declares auth is required, it must actually reject anonymous clients. Serving tools to unauthenticated callers is a real exposure.
