Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (4)
🟢rialto_list_tokens
List every token quotable on Rialto for Robinhood Chain (symbol, address, decimals, type). Public endpoint; call this before quoting to resolve symbols and decimals.
Input Schema
{
"type": "object",
"properties": {},
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢rialto_get_quote(sellToken, buyToken, sellAmount, taker, slippageBps, ...)
Get a best-execution swap quote from Rialto. Returns human-unit amounts, the guaranteed minimum, every fee line, route stats, and blockers (issues). sellAmount is a HUMAN decimal like "0.01", never raw units. Requires RIALTO_API_KEY.

}🟢rialto_preflight(quote, maxSlippageBps)
Validate a Rialto quote (as returned by rialto_get_quote) against baseline safety checks — issues, settlement sanity, staleness, slippage ceiling, fee cap, zero-output guard. Returns ok / refusals / warnings / notes. Run before any signing step.
Input Schema
{
"type": "object",
"properties": {
"quote": {
"type": "object",
"additionalProperties": {},
"description": "The full quote object returned by rialto_get_quote"

}
},
"required": [
"quote"
],
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}⚪rialto_build_unsigned_tx(quote)
Return the unsigned payload for a USER-signed wallet to complete: the tx object and, for Permit2 settlement, the EIP-712 typed data plus the byte offset where the wallet layer splices the 65-byte signature. This server never signs — it only shapes what a wallet needs to sign.
