What is RAVN

RAVN is a cross-chain swap execution engine, exposed here as a hosted MCP server. Point any MCP client at it and get native swap tools, no SDK, no signup, no API key.

The thing most swap APIs can't do: RAVN routes native Bitcoin, real BTC, not a wrapped token, as either the source or destination of a swap, alongside standard EVM and Solana routes. Every quote races 12 execution venues in parallel across 16 chains, and the best net output wins. 0% protocol fee on every route.

Tools

ravn_quote - best-priced route across all 12 venues for a given pair/amount
ravn_execute - turn a quote into a signable transaction, typed data, or a deposit address
ravn_status - normalized swap status (pending → processing → success)
ravn_health - which venues are live right now
ravn_btc_prepare_send - prep a native-BTC send

Try it

what would 25 USDC on Base get me in native bitcoin right now?

which RAVN venues are up?

Custody

RAVN never holds funds and the MCP server never asks for a private key. ravn_execute returns a payload for you to sign a transaction to broadcast, typed data to sign, or a deposit address to send to.

ravn_quote	Get a swap quote from RAVN — same-chain or cross-chain, across 16 chains including native (non-wrapped) Bitcoin and Solana as source or destination. Free, no API key or payment required. Returns a quoteToken; pass it to ravn_execute to get a signable/broadcastable execution payload.
ravn_execute	Turn a quoteToken from ravn_quote into an execution payload. Returns one of three shapes (executionType): TRANSACTION (sign and broadcast yourself), SIGNATURE (sign, RAVN submits), or DEPOSIT (send the input asset to a given address). RAVN never takes custody of funds — you always sign or send from your own wallet. TRANSACTION and SIGNATURE may also include an `approval` — an ERC-20 approve() you must broadcast and wait to be MINED before the transaction/signature, or it fails (reverts on TRANSACTION; on SIGNATURE the order is accepted and silently never fills). Only present when the sold token needs it — omitted for native-coin sells and already-approved tokens.
ravn_submit_signature	For a SIGNATURE-type ravn_execute result only: submit the signature(s) you collected (over typedData, and approvalData if present) to actually place the order. RAVN decodes the venue from quoteToken and routes to the right venue-specific submit path — you never touch a per-venue endpoint. Returns a statusRef — pass it to ravn_status as `ref` to poll this swap.
ravn_status	Poll the status of a swap by its quoteToken and the ref returned by ravn_execute (deposit address for DEPOSIT venues, statusRef for SIGNATURE venues). Status is authoritative where the venue exposes it; Jupiter is the one live venue that reports 'unknown' honestly rather than guessing.
ravn_health	Liveness check across every venue RAVN routes through — call before a swap if you want to know whether a route is degraded ahead of time.
ravn_tokens	RAVN's own listed token registry for one chain — populate a token picker without hardcoding one. This is "what RAVN knows about and might route", not a per-pair routability guarantee for any specific pair; call ravn_quote to check that.
ravn_tokens_resolve	Resolve an arbitrary token address to its metadata (symbol, name, decimals) via an on-chain read — for a paste-any-address flow, when the token isn't necessarily on ravn_tokens's list.
ravn_btc_coverage	For a swap where native BTC is the source, not every token on the destination chain is reachable. Returns which of ravn_tokens's list on `chainId` a BTC venue can actually route to, and how many venues serve each, so you can build a token list that matches what will really quote instead of discovering it one NO_LIQUIDITY at a time. BTC-as-source only — selling a token INTO BTC isn't restricted the same way (nearly any token can be sold into BTC), so this has nothing useful to say about that direction.
ravn_chains	Every chain RAVN lists a token registry for (see ravn_tokens). Static, doesn't change per request, safe to cache instead of hardcoding a chain table.
ravn_btc_prepare_send	Turns a DEPOSIT-type ravn_execute result (depositAddress + depositAmount) into a ready-to-sign PSBT, so you don't have to write your own UTXO selection and fee-estimation code. Fetches your UTXOs and the current network fee rate from mempool.space (public, no auth). RAVN never sees or touches a private key — sign the returned PSBT with your own wallet and broadcast it yourself. Only one signer is ever needed (unlike PSBT flows that require coordinating signatures across multiple UTXO-holding wallets), because every RAVN BTC-source venue resolves to a plain single-recipient payment.
