Common questions

Is yieldhunter safe?

It passed 5 of 5 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 30 days ago, and the latest version (1.0.0) reached the registry 3 months 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 on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

yieldhunter-connect

Public front door for yieldhunter.eth.

Risk-adjusted ranks. Research only. Not financial advice. Not RNWY Ethereum agent 12099. ERC-8004 on Base: 61006.

The full agent stays in a private repo. This repo only points at the live service.

Sibling

After ranks: a policy check via yieldsentinel-connect / yieldsentinel.eth (Base 63771).

No auto-sync between the two.

Connect snippet

Agent Plugin (Cursor / Grok marketplace)

This repo is also an Agent Plugins package:

  • plugin.json — manifest
  • mcp.json — remote Streamable HTTP MCP
  • LICENSE — MIT

Marketplace note (approval risk): this is DeFi / stablecoin research tooling for agents. It never custodies funds or executes trades. Curated marketplaces may still reject or delay listings that touch yield/DeFi topics. Research only — not deposit advice.

One-liner: Risk-adjusted ranks, then a policy check. Research only.
