Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 1 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability62
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 3446 tokens (~344/item across 10 items; 10 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety88
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 1 of 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "ravn_btc_prepare_send" implies "send" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Partial
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

ravn_btc_coverage How many BTC venues list each token ~128
For a swap where native BTC is the source: how many BTC venues list each of ravn_tokens's tokens on `chainId`. A ranking hint (a token more venues list is more likely to keep routing through one venue's outage), not a gate: ravn_quote decides, and tokens off RAVN's list route from BTC too. BTC-as-source only.
| Name | Type | Req | Description |
|---|---|---|---|
| apiKey | string | – | Your RAVN API key, if you have one — raises your rate limit |
| chainId | integer | yes | The destination chain to check BTC-source coverage on |
Structured output declared, but exposes no named fields.
No examples provided.
ravn_btc_prepare_send Prepare a signable Bitcoin transaction for a RAVN DEPOSIT ~422
Turns a DEPOSIT-type ravn_execute result (deposit.address + deposit.amount) into a ready-to-sign PSBT, so you don't have to write your own UTXO selection and fee-estimation code. If that result also has a `fee` (an integrator fee RAVN collects beside the deposit), pass its fee.address as feeAddress and fee.amount as feeAmountSats: the PSBT then pays it as a second output of the same transaction, which is the only place RAVN looks for it. 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 payment to the deposit address (plus RAVN's fee output, when there is one).
| Name | Type | Req | Description |
|---|---|---|---|
| amountSats | string | yes | deposit.amount from the ravn_execute DEPOSIT result, in satoshis |
| feeAddress | string | – | fee.address from the ravn_execute DEPOSIT result — REQUIRED whenever that result has a `fee`. RAVN's fee is paid as an extra output of this same transaction; leave it out and the fee is never paid |
| feeAmountSats | string | – | fee.amount from the ravn_execute DEPOSIT result, in satoshis — pass together with feeAddress |
| feeRateSatsPerVb | number | – | Omit to use mempool.space's current halfHourFee estimate |
| fromAddress | string | yes | Your Bitcoin address holding the UTXOs to spend — native SegWit (bc1q…) or Taproot (bc1p…) only |
| network | string | – | Defaults to mainnet |
| toAddress | string | yes | deposit.address from the ravn_execute DEPOSIT result |
Structured output declared, but exposes no named fields.
No examples provided.
ravn_chains List every chain RAVN supports ~68
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.
| Name | Type | Req | Description |
|---|---|---|---|
| apiKey | string | – | Your RAVN API key, if you have one — raises your rate limit |
Structured output declared, but exposes no named fields.
No examples provided.
ravn_execute Execute a RAVN swap quote ~471
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. An `approval.reset` (Ethereum USDT holding a partial allowance) goes first, mined, then the approval. A result with `sandbox: true` is a test: send nothing from it.
| Name | Type | Req | Description |
|---|---|---|---|
| apiKey | string | – | Your RAVN API key, if you have one — raises your rate limit |
| destinationAddress | string | – | Late-bound output recipient, honoured by venues that bind at execution time (Chainflip, Garden, Layerswap, Mayan, NEAR Intents, Rift, RAVN two-hop routes). Every other venue fixes the recipient when… |
| quoteToken | string | yes | The quoteToken returned by ravn_quote |
| refundAddress | string | – | Late-bound refund recipient if the swap fails, honoured by venues that read one at execution time (Chainflip, Garden, NEAR Intents, Rift). Every other venue, Mayan, Layerswap and RAVN two-hop routes… |
Structured output declared, but exposes no named fields.
No examples provided.
ravn_health Check RAVN venue health ~39
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.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
ravn_quote Get a RAVN swap quote ~1,501
Get a swap quote from RAVN — same-chain or cross-chain, across 18 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.
| Name | Type | Req | Description |
|---|---|---|---|
| allowNoMinimum | boolean | – | Let venues that enforce no minimum (today Rift) race even though slippageBps is set. Their quotes carry slippage.noMinimum true and fill at the venue's own rate: slippageBps does not protect them |
| apiKey | string | – | Your RAVN API key, if you have one — raises your rate limit |
| confidential | boolean | – | Settle privately via NEAR Intents' Confidential Intents so the deposit and payout can't be linked on-chain. Through this MCP server only NEAR quotes it (NO_LIQUIDITY if it can't, never a public fallb… |
| destinationAddress | string | – | Where output should land, if different from userAddress. Required here, at quote time, to get an executable quote from Relay (Bitcoin as the source), THORChain (Bitcoin either direction), Across (a S… |
| excludeVenues | array | – | Drop specific venues, e.g. a risk objection to one of them or ravn_health showing it degraded. An excluded venue is used nowhere in the route, including the steps of RAVN's multi-step routes (compose… |
| inputAmount | string | yes | Positive integer string, in the input token's smallest unit (no decimals) |
| inputChainId | integer | yes | Numeric chain id, e.g. 1=Ethereum, 8453=Base, -1=Bitcoin, -2=Solana — see ravn_chains for the full list, or ravn_health for live venue status |
| inputToken | string | yes | Token contract address, or 0xEeeeeEeeeEeEeeEeEeEeeeEEeeeeEeeeeeeeEEeE for the chain's native coin |
| onlyVenues | array | – | Race only these venues, e.g. ["bebop"] for an RFQ-only race. Every other venue is left out (including ones RAVN adds later); excludeVenues still applies on top. It covers every venue RAVN routes your… |
| outputChainId | integer | yes | Numeric chain id, e.g. 1=Ethereum, 8453=Base, -1=Bitcoin, -2=Solana — see ravn_chains for the full list, or ravn_health for live venue status |
| outputToken | string | yes | Token contract address, or 0xEeeeeEeeeEeEeeEeEeEeeeEEeeeeEeeeeeeeEEeE for the chain's native coin |
| rankingMode | string | – | best_output (default) picks the highest net output; fastest picks the quickest-settling quote within slippageBps |
| refundAddress | string | – | Where to refund the input asset if the swap fails. Selling native Bitcoin with userAddress set to a Bitcoin address and no refundAddress refunds to userAddress. Well-known sample addresses (e.g. bc1q… |
| slippageBps | integer | – | Max acceptable slippage in basis points. Setting it drops venues that enforce no minimum (today Rift) from the race unless allowNoMinimum is true |
| timeoutMs | integer | – | The race's time limit in milliseconds, counted from its start: once it has passed and some venue has priced the swap, slower venues are left out (with none priced yet, the first price ends the wait;… |
| userAddress | string | yes | Address the input asset will be sent from |
Structured output declared, but exposes no named fields.
No examples provided.
ravn_status Check RAVN swap status ~355
Poll the status of a swap by its quoteToken and ref from ravn_execute (statusRef, deposit address, or origin tx hash). Use the quoteToken execute returned — compose rebinds hop 1 onto hop 2's deposit. Status is authoritative where the venue exposes it; a swap the venue can't track reports 'unknown' rather than a guess.
| Name | Type | Req | Description |
|---|---|---|---|
| apiKey | string | – | Your RAVN API key, if you have one — raises your rate limit |
| quoteToken | string | yes | The quoteToken from ravn_quote — the venue is decoded from it |
| ref | string | yes | statusRef from ravn_execute when it returned one (always for DEPOSIT and SIGNATURE venues — it is the venue's own tracking key, which is not always the deposit address); otherwise the origin tx hash |
| txHash | string | – | The transaction that paid a fee the swap carries, where RAVN can't find it otherwise: a two-hop route's hop-1 tx, or the on-chain transaction that carried an execution's fee.transaction (Rift and pri… |
Structured output declared, but exposes no named fields.
No examples provided.
ravn_submit_signature Submit a signed RAVN order ~175
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.
| Name | Type | Req | Description |
|---|---|---|---|
| apiKey | string | – | Your RAVN API key, if you have one — raises your rate limit |
| approvalSignature | string | – | 0x Gasless only: signature over approvalData, when ravn_execute returned one |
| quoteToken | string | yes | The quoteToken from ravn_quote |
| signature | string | yes | Signature over the typedData from ravn_execute |
Structured output declared, but exposes no named fields.
No examples provided.
ravn_tokens List RAVN's token registry for a chain ~143
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.
| Name | Type | Req | Description |
|---|---|---|---|
| apiKey | string | – | Your RAVN API key, if you have one — raises your rate limit |
| chainId | integer | yes | Numeric chain id, e.g. 1=Ethereum, 8453=Base, -1=Bitcoin, -2=Solana — see ravn_chains for the full list, or ravn_health for live venue status |
Structured output declared, but exposes no named fields.
No examples provided.
ravn_tokens_resolve Resolve a token address to its metadata ~144
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.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | Token contract address / mint to resolve |
| apiKey | string | – | Your RAVN API key, if you have one — raises your rate limit |
| chainId | integer | yes | Numeric chain id, e.g. 1=Ethereum, 8453=Base, -1=Bitcoin, -2=Solana — see ravn_chains for the full list, or ravn_health for live venue status |
Structured output declared, but exposes no named fields.
