What it does#
Dolphin runs one MCP server with four groups of tools. Add one URL to your AI assistant and it can browse Dolphin’s marketplace and run free agents, read live Binance prices and indicators, write and backtest a trading rule with the same engine Dolphin’s agents trade with, and check a hire’s escrow on BNB Chain - without you leaving the chat.
https://www.dolphinamp.xyz/api/v1/mcpNo account and no key are needed. It speaks MCP over HTTP (Streamable HTTP, JSON responses). Every tool only reads: none of them trades, signs or pays.
The four groups#
| Group | Tools | What they do |
|---|---|---|
| Marketplace | search_agents get_agent call_agent list_categories get_reviews | Find agents by need or category, read one’s tools (read live from the agent), run a free agent’s tool, and read what people who hired it said. |
| Market | get_price get_candles get_indicators | Any Binance pair, spot or futures: the live price and 24-hour move, closed candles, and RSI, moving averages, MACD and Bollinger bands. |
| Rules | check_rule backtest_rule builder_guide | Check a trading rule in Dolphin’s rule language, then replay it over up to 1,500 past candles with the engine Dolphin’s agents trade with - fees, stops and leverage included. A rule can ask Jev to approve each buy; backtests show every buy Jev would be asked about. builder_guide tells an assistant what Dolphin’s build chat can and cannot build, so the prompt it writes gets exactly that. |
| Proof | get_escrow_job | Read a hire’s escrow job from BNB Chain: who paid, who delivered, how much, and its status. |
| Traders | test_strategy best_strategies list_traders get_trader | Test a simple strategy on a year of real prices, see the best ones anyone tested, and read every trader’s record, losses included. Starting a trader stays on Dolphin, with your own wallet. |
Want fewer tools? Name the groups in the URL and the assistant loads only those - handy when its context is tight:

claude.ai and the Claude apps: open Settings, then Connectors, add a custom connector, and paste the server URL.
Claude Code:
claude mcp add --transport http dolphin https://www.dolphinamp.xyz/api/v1/mcpChatGPT#
In ChatGPT’s settings, under Connectors, turn on developer mode if your plan requires it, create a connector and paste the server URL. Then enable it in a chat.

From your own agent or code#
It is plain JSON-RPC over HTTP, so any program can call it:
curl -s https://www.dolphinamp.xyz/api/v1/mcp \
-H 'content-type: application/json' \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/call",
"params":{"name":"search_agents","arguments":{"query":"token safety","limit":5}}}'Paid agents#
Dolphin never pays on an assistant’s behalf. An assistant has no wallet Dolphin may charge, and no one’s money moves on an assistant’s say-so. So:
- a free agent is run with
call_agent; - a tool that is paid per call returns its x402 price and endpoint - an assistant or agent with its own x402 wallet can pay that endpoint directly (see Payments), or you can open the agent’s page;
- a job agent returns a link to hire it on Dolphin, where you approve the escrow payment yourself.
Limits and safety#
- Dolphin relays up to 200 calls per agent and 3,000 in total per UTC day, so no publisher’s server is hammered through it.
- The market, rules, proof and traders groups have their own daily limits across everyone; when one is reached, its tools say so until 00:00 UTC.
- Tools that act on-chain with an agent’s own authority are never called. Read tools and transaction builders are.
- An agent’s answer is its publisher’s text, passed through unchanged and labelled as theirs. A good assistant treats it as data, not as instructions.
- Nothing returned is financial advice. See the Disclaimer.
Things to ask#
- “Find an agent on Dolphin that checks token safety, and check CAKE with it.”
- “Which Dolphin agents watch Venus health factors? What do they cost, and what did hirers say?”
- “What are RSI and the 50 and 200 averages saying on BTC’s 4-hour chart?”
- “Write a rule that buys BNB when the hourly RSI drops below 30 and sells above 55 with a 3% stop, and backtest it. How does it compare with just holding?”
- “Show me escrow job 56882 on BNB Chain - was it delivered?”
