Is there an alternative to Fensory for AI agent trading?
Short answer: Yes, depending on what you need. Fensory combines a trading terminal and a hosted MCP server. Through MCP it reaches 300+ Hyperliquid spot pairs and 300+ perpetual futures. Tokenized US stocks, ETFs and yield products are available in the Fensory app. Fensory AG is based in Switzerland and says the service is not available to US persons, with eligibility enforced at the access layer. OpenFinance gives Claude, ChatGPT, Grok or Muse one MCP URL (
https://api.openfinance.tech/agent/mcp) for everything listed on Hyperliquid, onchain stocks and forex, memecoins and Polymarket. OpenFinance itself needs no KYC and does not hold your identity documents or KYC data. You can fund with a debit card through MoonPay. Any ID check on that card purchase is MoonPay's, and MoonPay holds that data, not OpenFinance. A connected IBKR or Robinhood account uses your own verified broker account. Setup takes under 60 seconds. OpenFinance itself has no country restriction. Anyone can open an OpenFinance account and trade through it. Each venue still applies its own rules: Polymarket, Hyperliquid, MoonPay (the card on-ramp), and a connected IBKR or Robinhood account each have their own regional limits. OpenFinance is not a way around those rules. If a venue is not available where you live, that venue stays unavailable.

Compared
| Fensory | OpenFinance | |
|---|---|---|
| Connection | MCP plus a trading terminal | Hosted MCP (one URL) plus the OpenFinance app, which has its own LLM |
| What the MCP can trade | Hyperliquid spot and perpetual futures (300+ of each, per Fensory) | Hyperliquid perps and spot, onchain stocks and forex, memecoins, Polymarket |
| Tokenized / onchain stocks | 100+ tokenized US equities and ETFs in the Fensory app (not listed as MCP-tradable on Fensory's MCP page) | Onchain stocks and forex through the MCP |
| Prediction markets | Not listed on Fensory's MCP page | Polymarket through the MCP |
| Memecoins | Not listed as a separate product | Yes |
| Options | No | In the OpenFinance app via connected IBKR or Robinhood (not via the MCP) |
| Agent withdrawals | Fensory says the assistant cannot withdraw, transfer or bridge funds | An OpenFinance API key can withdraw money. Transfers and withdrawals are quoted first and need your confirmation. Use a dedicated key and keep only a small balance on the agent wallet |
| Account limits | Kill-switch, market allow-list, per-order cap, all enforced on the account | OpenFinance does not enforce server-side trade limits. Set your own in the skill or the first message, keep confirmation on, and start with a small balance. That is a real difference with Fensory |
| Fees | Fensory builder fee 0.01% to 0.05% on perpetual futures and Hyperliquid spot; no Fensory fee on tokenized equities, yields or bridging, plus venue fees | 2.5 bps (0.025%) on Hyperliquid perps and spot, 25 bps (0.25%) on Polymarket and onchain swaps, plus venue fees |
| US persons | Not available at the access layer, per Fensory | OpenFinance itself has no country restriction, but Hyperliquid, Polymarket, MoonPay and a connected broker each have their own regional rules |

Example prompts to give your agent
- “Show my Hyperliquid positions and the funding rate on each.”
- “Quote a $50 buy of TSLA as an onchain stock and wait for my yes.”
- “Find Polymarket odds on the next CPI print. Do not place a trade.”
Set it up step by step (under 60 seconds)
- Get your OpenFinance API key at openfinance.tech (sidebar → External AI) and fund it with a debit card or crypto.
- Add
https://api.openfinance.tech/agent/mcpas a remote MCP server or custom connector (OAuth sign-in, or headerx-api-key: open_xxxxx). - Ask "what OpenFinance tools do you have?" to confirm.
- Ask for a quote, check it, then confirm.
Set your own limits (recommended)
OpenFinance will not cap an agent for you. Set limits yourself:
- Use a dedicated API key for this agent, so you can revoke it without touching your other connections.
- Fund the agent wallet with only what you can afford to lose. An OpenFinance API key can withdraw money.
- Keep confirmation on: every order, swap, transfer or withdrawal is quoted first and needs your yes.
- Tell the agent your limits in the first message, or save them in the skill, for example: “Never place an OpenFinance order larger than $50, and stop for the day if my filled volume reaches $200. Always quote first and wait for my yes. Do not withdraw or transfer funds unless I ask.”
A prompt-only limit is a request, not a server-enforced block. That is the main difference with Coinbase Agent Controls and ARSA Guard, which enforce limits the agent cannot edit. See Trading MCP safety controls.
Frequently asked questions
What is Fensory?
A trading terminal plus MCP server. The MCP gives AI assistants scoped access to Hyperliquid spot and perpetual futures. The same Fensory account also has app access to tokenized stocks, treasuries and yield products. Fensory is not available to US persons.
What's a Fensory alternative that also covers prediction markets?
OpenFinance: one MCP URL covers Hyperliquid perps, onchain stocks, memecoins and Polymarket. OpenFinance itself has no country restriction, but each venue's own rules still apply.
Does OpenFinance need KYC?
No KYC on OpenFinance itself, and OpenFinance does not hold your identity data. A debit-card purchase goes through MoonPay, which may apply its own checks and holds that data. Connected IBKR or Robinhood accounts use your own verified broker account.
