dabble-me MCP Server Security Report
Private journal MCP server to search, analyze, and create Dabble Me entries securely via OAuth.
This server scored F. Run it behind runtime policy enforcement so one bad tool call can't become an incident.
- criticalNo command-injection sinks — 2 occurrences
Security controlslatest scored version v1.0.0
Each control is evaluated deterministically with evidence. The score is earned from passing controls; a failed guard caps it.

Model–MCP Runtime Guardrails
- Not checkedIndirect Prompt Injection (IPI) Defensesguardno tools extracted
Tool/prompt/resource text is free of hidden instructions that could hijack the agent.
- Not checkedStrict JSON Schema Enforcementno tool schemas found
Tool inputs are constrained (additionalProperties:false), so unexpected arguments can't be smuggled in.
- Not checkedUser-in-the-Loop / Approval Scopeguardno tools extracted
No over-broad or destructive tools (arbitrary shell, bulk-delete) that warrant human approval.
- 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 command-injection sinksguard2 occurrences
Untrusted tool input reaching a shell yields remote code execution.
app/assets/javascripts/lib/imagesloaded.pkgd.js:292app/assets/javascripts/lib/imagesloaded.pkgd.js:298Fix: Never pass tool arguments to a shell; use argv arrays with shell disabled.
- WarnCredentials sourced from environmentno env-based config detected
Reading secrets from env/secret stores avoids hardcoding them.
Fix: Read credentials from environment variables or a secret manager.
- WarnNo known-vulnerable dependencies1 of 84 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-r28c-9q8g-f849Fix: Upgrade the flagged dependencies past their fixed versions.
- WarnHas 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.
- 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.
- PassDependencies pinned (lockfile)lockfile present
A lockfile makes installs reproducible and resistant to silent dependency swaps.
- 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.
- 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.
- N/ANo install/post-install scriptsguardno published package
install hooks run arbitrary code on every consumer at install time.
- N/APackage name not typosquattingguardno published package
Names mimicking popular packages are a common malware delivery vector.
- N/APublished with provenanceno published package
Build provenance attests the artifact was built from the claimed source by CI.
- N/AEstablished maintainerno published package
Brand-new / single anonymous maintainers raise takeover and malware risk.
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.
- PassTransport Encryption (TLS)guardall remotes use HTTPS
Plaintext HTTP exposes traffic and bearer tokens to interception.
- PassIAM / Authentication ScopingOAuth / PRM handling detected
OAuth 2.1 / Protected Resource Metadata gates who can invoke tools.
- PassNetwork Exposureno bind-all detected
Binding 0.0.0.0 or exposing debug inspectors widens the attack surface.
- 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.
