Findings

Matches of fixed checks, with the text they matched.

1 warn
  • Warnprepare_quote

    The server marks "prepare_quote" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

    Matched text

    annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The input addresses people (input.recipient): what it sends cannot be taken back.

    Why it is in this group

    • The input addresses people (input.recipient): what it sends cannot be taken back.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    • Warn

      The server marks "prepare_quote" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

      What this check looks for
    Description, as the server wrote it
    Prepare an on-chain BlazePhoenix quote to run on YOUR OWN RPC. Returns the exact eth_call (Quoter address + calldata, as a ready JSON-RPC request and a curl line) plus a `request` object. Run the call on your node, then pass `request` and the result hex to decode_quote. This server performs no RPC.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Decode the eth_call result YOUR node returned for a prepare_quote call: net output after the 0.28% fee, the minimum the Router enforces on-chain, price impact, the Phoenix Check verdict (ok / caution / danger / blocked — fails closed) and, with a recipient, verified unsigned calldata. Pure computation.

    Annotations the server declares

    Why it is in this group

    • The name "get_abi" says "get": a word for reading.
    Description, as the server wrote it
    The JSON ABI of one BlazePhoenix contract, generated from the Solidity sources, with the source revision it was built from. Use it to encode your own calls to the addresses get_deployments returns, or pass `errors` to decode a revert reason from a failed swap or quote. Returns { contract, revision, abi }; an unknown name returns ok:false with the accepted list. Pure lookup, no RPC.

    Why it is in this group

    Description, as the server wrote it
    The versioned BlazePhoenix deployment registry: Core, Hub, Solver, Quoter and Router addresses per chain and protocol version (1.0.0 live; 2.0.0 the final generation), and which version each chain runs now.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
