How to choose
- Read-only first. Data and analytics servers cannot move funds. Be far more careful with anything that can sign or trade.
- Keep your keys. Prefer servers that prepare unsigned transactions so that you approve each one in your own wallet.
- Check a token before buying. Rug-pull and honeypot checks reduce risk but never remove it.

How we picked these
We read each listing's tools and put the closest fit for this job first. Hosted servers must pass a real MCP handshake in our daily check to stay on this page, and local servers are reviewed from their source or package. That shows a server responds, not how well it works for you, and we don't run every tool in production.
Frequently asked questions
Which of these MCP servers work without signing in?
OwlChart, BlockVectra MCP, ScrapeMole Onchain, PerpRadar and TASignal are among the 17 that answered our latest live check with no account or key.
Can an AI agent trade crypto through MCP?
Some servers allow it, usually with limits you set. Others only build an unsigned transaction for you to approve. Never give an agent more funds than you can afford to lose.
Can MCP check if a token is a scam?
Token safety servers look for warning signs such as honeypot behavior and concentrated holders. A pass is not a guarantee that a token is safe.
How often is this list updated?
Every hosted server here is re-checked daily with a real MCP handshake, and a server drops off this page while it fails that check. Last check: Nov 8, 2026.
