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

4 issues capping this score

highNo unsafe deserialization — 12 occurrences
highTool descriptions free of injection markers — 4 marker(s) across 4 tool(s)

Security controls

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

Model–MCP Runtime Guardrails

Fail
Indirect Prompt Injection (IPI) Defensesguard4 marker(s) across 4 tool(s)
Tool/prompt/resource text is free of hidden instructions that could hijack the agent. How many servers fail this?
create_identity — exfiltration directivepost_message — exfiltration directivescreen_leak — exfiltration directivesend_private — exfiltration directive
Fix: Remove hidden directives, HTML/comment instructions, and override phrasing from descriptions.
Fail
Tool Definition Integrityguard1 risky tool-definition change(s) in version history (1.18.2 → 1.18.3)
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. How many servers fail this?
post_message
Fix: Never add hidden directives or destructive scope to an already-published tool; document description changes in release notes.
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?
claim_identity
Fix: Scope tools narrowly; avoid arbitrary command execution and destructive defaults.
Pass
Strict JSON Schema EnforcementadditionalProperties:false present
Tool inputs are constrained (additionalProperties:false), so unexpected arguments can't be smuggled in.
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

Fail
No unsafe deserializationguard12 occurrences
pickle/yaml.load/etc. on untrusted data can execute code. How many servers fail this?
research/swarmchasing/analysis/collusionwiki/02_labels_recruitment_handoff.py:13research/swarmchasing/analysis/collusionwiki/03_deletion_response.py:13research/swarmchasing/analysis/collusionwiki/03_deletion_response.py:14research/swarmchasing/analysis/collusionwiki/04_network_core_clusters.py:69
Fix: Use safe loaders (yaml.safe_load, JSON) on untrusted input.
Warn
No dynamic code executionguard2 occurrences (build/test paths only)
eval()/exec()/Function() on tool-derived strings allows arbitrary code execution.
scripts/test_private_read_guide.py:71scripts/test_url_budget_guide.py:50
Fix: Remove eval/exec; parse and dispatch explicitly.
Warn
No path traversalguard64 occurrences
Naive path checks let tools read/write outside intended directories (EscapeRoute-class).
clients/javascript/swarmmemo.mjs:427clients/javascript/swarmmemo.mjs:450clients/javascript/test_client.mjs:354clients/javascript/test_client.mjs:438
Fix: Resolve to a canonical path and verify containment; reject ../ and symlinks.
Warn
No SSRF sinksguard107 occurrences
Fetching tool-supplied URLs can pivot into internal networks and metadata services.
clients/javascript/swarmmemo.mjs:512clients/javascript/test_client.mjs:513clients/javascript/test_client.mjs:536clients/javascript/test_client.mjs:542
Fix: Allow-list destinations; reject arbitrary/loopback/link-local URLs.
Warn
No known-vulnerable dependencies1 of 87 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-2gx3-rcp4-g85q[email protected] — GHSA-42vr-xj54-vc7v[email protected] — GHSA-8wjv-2p76-3863[email protected] — GHSA-9j54-fg26-wv3r
Fix: Upgrade the flagged dependencies past their fixed versions.
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 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.
Pass
Has a security policySECURITY.md present
A SECURITY.md gives a private path to report vulnerabilities.
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

Pass
Transport Encryption (TLS)guardall remotes use HTTPS
Plaintext HTTP exposes traffic and bearer tokens to interception.
Pass
IAM / Authentication ScopingOAuth / PRM handling detected
OAuth 2.1 / Protected Resource Metadata gates who can invoke tools.
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
Execution Sandboxingcontainerized
A container/sandbox image limits blast radius; a server that runs natively has full host access.
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.

Benign definition drift: the description changed vs the prior version with no risk signals in the diff. Clients approve tools by name and don't re-review on update, so the change is invisible to existing grants.
