Cipher — Bittensor Subnet Screener
Real-time Bittensor subnet screener: prices, momentum, flow, whale signals, TAO forecast via MCP.The vendor's description, from its MCP Registry listing.
- Warning: 8 of 8 tools do not say whether they can change things.
Nothing failed, but there is something to know or fix. Public audit: we connect as an AI client would, list the tools and check what they say. We do not run them. How we audit

- YesConnected in 173 ms.
- Sign-up?
- None neededIt answered without any account or key.
- Can it change things?
- Doesn't sayIts tools do not say whether they only read, so treat them as able to change things.

What we checked
Security
Passed: Connections are encrypted (HTTPS).
Passed: No hidden instructions found in tool text.
Safety labels
Warning: 8 of 8 tools do not say whether they can change things.
MCP lets a server label each tool as read-only or destructive, so clients can ask the user before risky calls. Unlabelled tools are treated as able to change things.

Tools (8)
As the server describes them. The labels are the server's own: it says whether each tool only reads or can change things.
