- Basic checks: 3 of 3 passed
- Runs on the maker’s server: what you ask it goes through their server.
- Can do 3 things (tools) scan_solidity_preview, scan_solidity_full, payment_terms
- The registry lists no key to fill in.
You need

What it can do
Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
scan_solidity_previewFREE Solidity security check (Slither). Detects known vulnerability patterns (reentrancy, unchecked calls, tx.origin auth, arbitrary ETH sends and more) and returns severity counts plus High/Medium detector names. Use after writing or changing a contract and before deployment. In
scan_solidity_fullOPTIONAL, PAID ($1.00 USDC on Solana via x402). Structured Slither findings for Solidity: detector, impact, confidence, description and file/line locations, for fixing each issue. Without a valid x402 payment in _meta['x402/payment'] it returns the payment terms and does NOT scan
payment_termsFREE. Price, recipient, network, asset and how to pay for scan_solidity_full.

Common questions
Is Kestrova: Solidity Vulnerability Scan safe?
It passed 3 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?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.4.0) reached the registry 8 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
