Morpho MCP

Morpho (Blue) over MCP on Ethereum and Base — market discovery with live APYs via the official Blue API, per-address positions computed from on-chain state (supplied assets, posted collateral, debt with accrued interest, health factor), local health-factor previews, and construction-only lend/borrow/repay/withdraw transactions encoded from the pinned singleton ABI. Free, no API key.

Endpoint

POST https://morpho-mcp.yeetful.com/mcp

Tools

• markets / market_info — curated markets with live supply/borrow APYs, utilization, LLTV, size; one market in depth
• position — supplied (earning), collateral posted, debt with accrued interest, health factor for any address
• preview — health factor AFTER a hypothetical action, computed locally before anything is built
• build_lend / build_supply_collateral / build_borrow / build_repay / build_withdraw / build_withdraw_collateral — unsigned transactions the user signs

Safety

Signature-free by construction — reads come from on-chain state and Morpho's public API; the build_* tools encode calldata locally against the pinned, bytecode-verified singleton and return unsigned transactions for the USER's wallet to sign. Builds fail closed on balances, borrowing power, liquidity, and thin health factors. No keys held, nothing submitted. Designed to flow into Yeetful's guardrail + sign pipeline.
