Common questions

Is Entropy0dev MCP safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ENTROPY0_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 6 months ago, and the latest version (0.1.3) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@entropy0/mcp

MCP server for Entropy0 — source trust and URL safety tools for AI agents.

Before your agent navigates a URL, fetches content, or submits credentials, Entropy0 tells it whether the domain is safe. Returns a recommended action (proceed, proceed_with_caution, sandbox, or deny) based on trust, threat, and structural anomaly signals.

Install

npx -y @entropy0/mcp

Or add to your MCP client config:

"mcpServers": { "entropy0": { "command": "npx", "args": ["-y", "@entropy0/mcp"], "env": { "ENTROPY0_API_KEY": "sk_ent0_your_key_here" } } } }

Get an API key at entropy0.ai.

Tools

`check_url`

Evaluate whether a URL is safe to interact with.

check_url({ url: "https://example.com", interaction: "navigate" })

Returns trust score, threat score, recommended action, and reason codes.

`check_domain`

Evaluate a bare domain name.

check_domain({ domain: "example.com" })

Response

"recommended_action": "proceed", "scores": { "trust": { "score": 88, "confidence": 0.91 }, "threat": { "score": 4, "confidence": 0.87 }, "deviation": { "score": 11, "confidence": 0.84 } }, "decision": { "reason_codes": ["STRONG_TRUST_HISTORY", "LOW_THREAT_SIGNALS"] }, "identity_assessment": { "claimed_entity": "stripe.com", "posture": "strongly_supported_entity_domain", "confidence": "high", "analyst_note": "Multiple independent structural signals support a stripe.com relationship." } }
