This server scored F. Run it behind runtime policy enforcement so one bad tool call can't become an incident.

Security controls

Deterministic, evidence-backed. Score earned from passing controls; a failed guard caps it.

Model–MCP Runtime Guardrails

  • Fail
    Indirect Prompt Injection (IPI) Defensesguard2 marker(s) across 2 tool(s)

    Tool/prompt/resource text is free of hidden instructions that could hijack the agent. How many servers fail this?

    goodearth_request_credential_channel — exfiltration directivegoodearth_receive_credentials — exfiltration directive

    Fix: Remove hidden directives, HTML/comment instructions, and override phrasing from descriptions.

  • Fail
    User-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?

    goodearth_delete_operator_credential

    Fix: Scope tools narrowly; avoid arbitrary command execution and destructive defaults.

  • Warn
    Strict JSON Schema Enforcementschemas not strict

    Tool inputs are constrained (additionalProperties:false), so unexpected arguments can't be smuggled in.

    Fix: Set additionalProperties:false and require explicit parameters on every tool.

  • Warn
    Tool Definition Integrityguard9 tool description(s) drifted after publish (no risk signals in 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.

    goodearth_session_statusgoodearth_request_npub_proofgoodearth_receive_npub_proofgoodearth_check_proof_status

    Fix: Never add hidden directives or destructive scope to an already-published tool; document description changes in release notes.

  • Pass
    In-Session Definition Integrityguardno call-gated or call-time tool definition changes

    Tool and prompt definitions stay fixed during a session — they don't change after a few calls, which is how runtime-gated rug-pulls slip past one-time review.

Application Security Checks

  • Warn
    No path traversalguard7 occurrences

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

    frontend/functions/calendar/[token].js:25frontend/functions/calendar/[token].js:26frontend/public/sw.js:37frontend/public/sw.js:92

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

  • Warn
    No SSRF sinksguard16 occurrences

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

    frontend/public/sw.js:53frontend/public/sw.js:70frontend/public/sw.js:82frontend/src/lib/family.ts:39

    Fix: Allow-list destinations; reject arbitrary/loopback/link-local URLs.

  • Warn
    No known-vulnerable dependencies4 of 133 runtime deps vulnerable; worst critical

    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-58mr-gqgx-xq4g[email protected] — GHSA-hrr3-gc8f-f4qj[email protected] — GHSA-qw65-cvwx-89v3[email protected] — GHSA-hxh3-vqpv-xpqv

    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.

  • Warn
    Adoption & popularitylimited adoption

    A small, capped nudge from stars/downloads — widely-used servers get more eyes on bugs. It can never offset a real security failure.

    Fix: Adoption grows naturally with real-world use; this never gates the score.

  • 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
    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 licenseApache-2.0

    A clear license is required for legal enterprise use.

  • 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
    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
    Transport Encryption (TLS)guardall remotes use HTTPS

    Plaintext HTTP exposes traffic and bearer tokens to interception.

  • Pass
    No Token Passthroughguardno inbound token forwarded downstream

    The client's token is never forwarded to downstream APIs — the server obtains its own, correctly-scoped credential instead.

  • Pass
    Network Exposureno bind-all detected

    Binding 0.0.0.0 or exposing debug inspectors widens the attack surface.

  • Not checked
    DNS-Rebinding ProtectionHTTP transport not found in source

    HTTP endpoints reject requests carrying an unlisted Origin, so a malicious web page can't drive the server through the user's browser.

  • 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.

AI-flagged — for review

Observations from an AI review of tool descriptions. These are advisory only and do not affect the score — they can be noisy and need human judgement.
