No longer in the registry. The MCP registry stopped listing this server as of 11 Sept 2026. This page stays available because the measurement was real, but the server is excluded from search, rankings, and Vouch’s corpus counts. A published behaviour score is never recomputed or removed — it reflects what was measured while the server was listed.

Tools

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.
shallow
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.
shallow
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.
shallow
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.
shallow
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; some venues (Rift, Jupiter, Bebop, 0x Gasless) report 'unknown' honestly rather than guessing.
