mund scores 37/100 (grade F) on the Canopii Trust Index, and carries 2 confirmed security failures that cap its score: Tool descriptions free of injection markers and No over-broad / destructive tools. It passes 13 of the 25 controls that apply to it.

What security issues does mund have?

mund fails 2 controls: Tool descriptions free of injection markers and No over-broad / destructive tools. Each failure on this page carries the evidence behind it — the file and line, dependency, or CVE that decided it.

How reliable is the security score for mund?

We could evaluate 98% of the controls that apply to mund. 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.

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 v0.1.12

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

Model–MCP Runtime Guardrails

Fail
Indirect Prompt Injection (IPI) Defensesguard1 marker(s) across 1 tool(s)
Tool/prompt/resource text is free of hidden instructions that could hijack the agent. How many servers fail this?
Prompt Injection - Ignore Instructions — 'ignore previous' override
Fix: Remove hidden directives, HTML/comment instructions, and override phrasing from descriptions.
Fail
User-in-the-Loop / Approval Scopeguard4 over-broad tool(s)
No over-broad or destructive tools (arbitrary shell, bulk-delete) that warrant human approval. How many servers fail this?
Potential Shell InjectionRecursive Force DeletePrompt Injection - System Prompt Extractionmund_validate_command
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.
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.

Application Security Checks

Warn
No path traversalguard2 occurrences
Naive path checks let tools read/write outside intended directories (EscapeRoute-class).
src/tools/mcp-scanning.ts:218src/tools/monitoring.ts:258
Fix: Resolve to a canonical path and verify containment; reject ../ and symlinks.
Warn
No SSRF sinksguard3 occurrences
Fetching tool-supplied URLs can pivot into internal networks and metadata services.
src/notifications/slack.ts:50src/notifications/teams.ts:75src/notifications/webhook.ts:32
Fix: Allow-list destinations; reject arbitrary/loopback/link-local URLs.
Warn
Dependencies 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).
Warn
Published 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.
Warn
Established maintainersingle maintainer
Brand-new / single anonymous maintainers raise takeover and malware risk.
Fix: Publish under an established account/org; add multiple maintainers.
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 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 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.
Pass
No install/post-install scriptsguardno install scripts
install hooks run arbitrary code on every consumer at install time.
Pass
Package name not typosquattingguarddistinct package name
Names mimicking popular packages are a common malware delivery vector.
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.
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.

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.
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.
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.
