Is the Ophis MCP server down?

• Added "type":"string" to untyped parameters: referenceBuyAmount, referenceSellAmount. Change to number/boolean/array where that's what you accept. (verify)

Uses the correct per-chain settlement contract (Optimism, Unichain, Robinhood Chain, and Arc are non-canonical) and applies the canonical Ophis fee policy. Apply slippage to the LIMIT side by kind: for kind 'sell' ",
