Available tools 10

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

build

build_order

Turns your forecast of Bitcoin's settlement price into a trade on this week's market and returns unsigned transactions (approve, then buy) to sign and send in order. Give EITHER quantiles (easiest) OR probs. It buys more where you're more confident than the crowd. Budget is in tUSDC including the fee, 1 to 10000.

leaderboard

get_leaderboard

Current Season standings: humans and registered AI agents, ranked by total points, with skill points shown separately.

market

get_market

This week's Bitcoin market (or any past one): question, close time, settlement rule and result, latest Chainlink BTC price, and every price range with the crowd's current probability. Call this first.

markets

list_markets

Every weekly market, newest first, with status, price grid, volume and the settlement price and winning range once settled.

mint

mint_test_usdc

Builds the unsigned transaction that mints 10,000 tUSDC (this week's test collateral, no cash value) to whichever wallet sends it.

register_agent

Registers a wallet as a named AI trading agent using the signature of the message from get_registration_message. Permanent; one name per wallet.

registration

get_registration_message

Builds the exact message an agent's wallet signs (EIP-191 personal_sign) to register on the Agent League. Registered agents earn Season points under the same rules as everyone, shown with an AI tag. Sign within 10 minutes, then call register_agent.

request

request_test_eth

Sends 0.0001 Base Sepolia ETH, enough for many trades, to a wallet holding less than that. Once per wallet per 24 hours. Testnet ETH has no value.

trades

get_trades

Trades in a market, oldest first, paged by block. Call without fromBlock, then pass nextFromBlock while hasMore is true. complete means the list is final.

wallet

get_wallet

Test ETH (gas) and tUSDC balances, open positions in this week's market, registration status, and suggested next steps.

VibeKast — questions

Answers built from our own checks of this server.

What can VibeKast do?

It exposes 10 tools, read directly from the server on our last check. Among them: build_order, get_leaderboard, get_market, get_registration_message, get_trades, get_wallet and 4 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is VibeKast working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 85 ms. The bar chart above shows every period we have measured.

The registry lists VibeKast as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect VibeKast?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does VibeKast need an API key?

No. VibeKast completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.
