Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 497 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name ravn.

  • Pass
    Lists tools

    tools/list returned 10 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 497 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 497 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    43 of 43 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Fail
    Website matches publisher

    The website host does not match the reverse-domain namespace.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass

ravn_btc_coverage

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.

Discovered
ravn_btc_prepare_send

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).

Discovered
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.

Discovered
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. 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.

Discovered
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.

Discovered
ravn_quote

Get a swap quote from RAVN — same-chain or cross-chain, across 19 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.

Discovered
ravn_status

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.

Discovered
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.

Discovered
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.

Discovered
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.
