Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
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 8 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 Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2101 tokens (~210/item across 10 items; 10 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management87
- Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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
How do I install the RAVN MCP server?
RAVN is a hosted endpoint at https://app.ravn.exchange/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

ravn_btc_coverage Which tokens actually route from native Bitcoin ~165
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.
| 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 ~251
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.
| Name | Type | Req | Description |
|---|---|---|---|
| amountSats | string | yes | depositAmount from ravn_execute, in satoshis |
| 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 | depositAddress from ravn_execute |
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 ~364
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.
| Name | Type | Req | Description |
|---|---|---|---|
| apiKey | string | – | Your RAVN API key, if you have one — raises your rate limit |
| destinationAddress | string | – | Late-bound output recipient, for venues that support binding it at execution time (e.g. NEAR Intents, Garden, Chainflip, Rift). Does NOT apply to Relay, Across, Eco, or THORChain — those fix the reci… |
| quoteToken | string | yes | The quoteToken returned by ravn_quote |
| refundAddress | string | – | Late-bound refund recipient if the swap fails, for venues that support binding it at execution time. Does NOT apply to a Bitcoin-source Relay or THORChain quote — both fix the refund address at quote… |
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 ~613
Get a swap quote from RAVN — same-chain or cross-chain, across 17 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 |
|---|---|---|---|
| apiKey | string | – | Your RAVN API key, if you have one — raises your rate limit |
| 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 from this race, e.g. a risk objection to one of them or ravn_health showing it degraded. Naming a venue that was never eligible for this pair is a no-op, not an error |
| 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 |
| 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. Required here, at quote time, for a Bitcoin-source Relay or THORChain quote — neither has an execute-time re-bind, so omitting it returns a priced-b… |
| slippageBps | integer | – | Max acceptable slippage in basis points |
| 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 ~139
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.
| 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 | deposit address (DEPOSIT venues) or statusRef (SIGNATURE venues) from ravn_execute |
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.
No examples provided.
What is the RAVN MCP server?
RAVN is an MCP server listed in the public MCP registry as exchange.ravn/ravn. Cross-chain swap aggregator across 16+ chains, incl. native Bitcoin/Solana. 0% fees, non-custodial. This page covers its hosted endpoint (https://app.ravn.exchange/api/mcp).
Is the RAVN MCP server safe to use?
RAVN scores 77 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the RAVN MCP server expose?
RAVN exposes 10 tools: ravn_quote, ravn_execute, ravn_submit_signature, ravn_status, ravn_health, and 5 more. Their descriptions and schemas cost roughly 2,101 tokens of context every time the server is loaded.
Does the RAVN MCP server require authentication?
No. We connected to RAVN without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the RAVN MCP server still maintained?
RAVN is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
