What it can do

Tool names and descriptions exactly as the server reported them on Nov 12, 2026. The maker wrote them, not us; we show them as plain text.

  • bull_create_rfq

    Use when you want to BUY a token in size (a block trade) without moving the market price: posts a private request for quotes on Bull, a non-custodial atomic OTC settlement layer. Returns an rfqId; sellers answer with sealed quotes only you can read. Optional maxPrice limit and we

  • bull_list_rfqs

    Use when you SELL or hold a token and want to find buyers: lists open requests for quotes on Bull (token, size in USD, window, buyer's price limit). Returns rfqIds to answer with bull_send_quote. Public, no signature needed. Not for finding market prices.

  • bull_send_quote

    Use when you want to SELL tokens to a buyer who posted an RFQ: sends a sealed quote (token amount and total ETH price) that only the buyer sees. Returns a quoteId. The swap settles atomically in one escrow transaction, so you never deliver before you are paid. Not for listing pri

  • bull_get_quotes

    Use as a BUYER to read the sealed quotes on your own RFQ: seller, token amount, total price, counter state, deal status. Returns a list of quotes with quoteIds. Only the RFQ's buyer can read it. Signed: the first call returns a message to sign; call again with the same arguments

  • bull_counter_quote

    Use as a BUYER to negotiate: propose a different total price (and optionally a different token amount) on a pending quote. Returns the stored counter. The seller can answer with bull_revise_quote. Works only while the quote is pending. Signed: the first call returns a message to

  • bull_revise_quote

    Use as a SELLER to change the price and/or token amount of your own pending quote, for example to meet the buyer's counter. Returns the new terms. The buyer then accepts with bull_accept_quote. Works only while the quote is pending. Signed: the first call returns a message to sig

  • bull_accept_quote

    Use as a BUYER to accept a quote. Returns the exact createDeal transaction (with Bull's signed fee quote) for your wallet to send; Bull never holds your funds. Then call bull_attach_deal with the dealId from the DealCreated event. Safe to call again to refresh the fee quote. Sign

  • bull_attach_deal

    Use as a BUYER after sending createDeal: report the dealId. Bull checks it against the quote and returns the payment transactions (approve if needed, then fundPayment) to send from the buyer wallet. When the seller deposits, the swap settles in that transaction. Signed: the first

  • bull_deposit_plan

    Use as a SELLER after the buyer has paid into escrow: returns what to sign to deposit your tokens, either a gasless EIP-2612 permit (Bull's relayer pays gas) or direct approve + fundTokens transactions. Fails with not_ready until the buyer has funded. Signed: the first call retur

  • bull_deposit

    Use as a SELLER to submit the signed permit from bull_deposit_plan. Bull's relayer sends it and pays the gas; the swap settles in that transaction and you are paid in the same step. Returns the transaction hash. Signed: the first call returns a message to sign; call again with th

  • bull_quote_status

    Use as BUYER or SELLER to check a quote and its onchain deal: status (pending, confirmed, funded, released), dealId, counter, who has funded. Poll this or use webhooks. Only the two parties can read it. Signed: the first call returns a message to sign; call again with the same ar

  • bull_reject_quote

    Use as a BUYER to reject a quote you do not want. Returns status rejected. Not needed for quotes that simply expire. Signed: the first call returns a message to sign; call again with the same arguments plus timestamp and signature.

  • bull_get_deal

    Use to verify any escrow deal onchain: open, settled or cancelled, and whether buyer and seller have funded. Public, no signature needed. Returns the deal state read from the contract.

  • bull_get_receipt

    Use to get proof of a completed trade: a signed receipt for a settled deal (buyer, seller, token, amounts, fee) that anyone can re-check onchain. Public. Fails with not_settled for deals that are still open.

  • bull_stats

    Use to check Bull's track record: number of settled deals, total volume, open RFQs and the latest settled deals, read from the escrow contract. Public, no signature needed.

  • bull_info

    Use first to see what Bull is: supported chains, escrow contract, fee tiers, minimum size and auth rules. Public. Bull is a non-custodial atomic OTC/RFQ settlement layer.

Common questions

Is Bull OTC safe?

It passed 3 of 3 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 –, and the latest version (1.0.0) reached the registry 2 days 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?
