MCP Servers by @cyanheads v1.0.0 B PASS 1 flag

Review an MCP server for common security gaps: LLM-facing surfaces as injection vector (tools, resources, prompts, descriptions), scope blast radius, destructive ops without consent, upstream auth shape, input sinks (URL / path / roots / shell / schema strictness / ReDoS), tenant isolation, leakage through errors and telemetry, unbounded resources, and HTTP-mode deployment surface. Use before a release, after a batch of handler changes, or when the user asks for a security review, audit, or hardening pass. Produces grouped findings and a numbered options list.

Capabilities below are detected automatically by an open-source scanner that reads the skill's text and scripts (see how this is computed). Not measured means the scanner couldn't make a confident call — it is NOT a green check, and you should treat it as a possible red flag until a human or a stronger scanner has measured it.

1 Red flags things this skill can do that affect your security or funds

⚠
Can execute shell runs arbitrary shell commands on your machine

9 Cleared by scanner we scanned the skill's text & scripts and found no evidence of these

✓
Can move funds this skill can sign and send transactions on your behalf
✓
Requires private key you must hand over a private key, mnemonic, or wallet config
✓
Requires hosted operator depends on a third-party hosted service to function
✓
Uses remote install script setup pipes a remote shell script (curl | sh class)
✓
Mutable remote runtime runs remote code that can change behavior without a local diff
✓
Can install code installs software at setup time (npx, pip, brew, etc.)
✓
Can browse the web fetches arbitrary URLs at runtime
✓
Can write files writes to your local filesystem
✓
Can spawn sub-agents delegates to other skills or sub-agents

1 Not measured yet scanner couldn't make a confident call — treat as a possible red flag

Ingredients (services this skill talks to)

We did not find any well-known hosted services in this skill's text or scripts. This does NOT mean the skill is local-only — it might use services we don't yet recognize, or talk to them through code paths our scanner can't reach. A complete dependency list (every package, library, and binary, with integrity hashes) is on the roadmap; today we only show recognized hosts.

Audits

No one has audited this skill yet. That is different from “audited and clean” — it just means no professional reviewer (a security firm, the CryptoSkill team, or a verified independent researcher) has signed off on it. There are no audit reports to read. How reviewer levels work →
