Morpho (Free)

DeFiFREERoutes in chatBaseEthereum

Morpho (Blue) lending on Base and Ethereum, computed from on-chain state, free and non-gated: curated markets with live supply/borrow APYs, per-market deep-dives, full account positions (supplied, collateral, debt, health factor), health-factor previews, and construction-only build_* tools that return UNSIGNED approve→act transactions the user signs — lend, post/withdraw collateral, borrow, repay, withdraw. Never holds keys, never signs, never submits. Rate-limited. By Yeetful.

Routability

can the router discover, pick, and call it?

Not yet graded. Diagnostics check param schemas, description quality, live health, and run the actual routing planner against this service’s own tools — construction only, nothing is paid or executed.

Tools

POST/mcp/marketsstart here
via Yeetful (free)morpho-mcp.yeetful.com
Morpho (Blue) lending markets on Base or Ethereum: loan/collateral pair, supply & borrow APY, utilization, LLTV, and market size in USD. Curated (listed) markets by default; includeUnlisted adds permissionless ones. Answers 'what can I lend/borrow on Morpho?' — use the returned 32-byte marketId (never a symbol) with the build_* tools.
2 parameters
- chainIdnumberbody
  Chain id: 8453 = Base (default), 1 = Ethereum mainnet. Market ids are chain-specific — use the chainId the market came from.
- includeUnlistedbooleanbody
  Also show permissionless (unvetted) markets. Default false.
POST/mcp/positionstart here
via Yeetful (free)morpho-mcp.yeetful.com
A wallet's Morpho position on Base or Ethereum, computed from on-chain state: supplied assets (earning), posted collateral, borrowed debt with accrued interest, borrowing power, and health factor per market. This is the 'show my Morpho position / can I get liquidated?' tool. Scans the 100 largest indexed markets by default; pass marketIds to narrow or to reach a niche market.
3 parameters
- userstringbodyrequired
  EVM address (0x…) of the account — pass "$USER_ADDRESS" for the connected user.
- chainIdnumberbody
  Chain id: 8453 = Base (default), 1 = Ethereum mainnet. Market ids are chain-specific — use the chainId the market came from.
- marketIdsstringbody
  Specific 32-byte market ids to check (array, max 20). Omit to scan all known markets.
POST/mcp/market_info
via Yeetful (free)morpho-mcp.yeetful.com
One Morpho market in depth, straight from the chain: loan + collateral assets (addresses, decimals), LLTV, live supply/borrow APY, utilization, available liquidity, fee, and the oracle's collateral price. Use before lending or borrowing to sanity-check the market.
2 parameters
- chainIdnumberbody
  Chain id: 8453 = Base (default), 1 = Ethereum mainnet. Market ids are chain-specific — use the chainId the market came from.
- marketIdstringbodyrequired
  The 32-byte Morpho market id (0x…, 64 hex chars) from `markets` — NEVER a token symbol or address.
POST/mcp/preview
via Yeetful (free)morpho-mcp.yeetful.com
Simulate a lend/supply_collateral/borrow/repay/withdraw/withdraw_collateral BEFORE building it: health factor now vs after, borrowing power after — computed locally from live on-chain state and the market's oracle. Nothing is built or signed. Use this before build_borrow / a large build_withdraw_collateral so the user sees the health-factor impact first.
5 parameters
- actionstringbodyrequired
  One of "lend" | "supply_collateral" | "borrow" | "repay" | "withdraw" | "withdraw_collateral".
- userstringbodyrequired
  EVM address (0x…) of the wallet the action would run as — pass "$USER_ADDRESS" for the connected user.
- chainIdnumberbody
  Chain id: 8453 = Base (default), 1 = Ethereum mainnet. Market ids are chain-specific — use the chainId the market came from.
- marketIdstringbodyrequired
  The 32-byte Morpho market id (0x…, 64 hex chars) from `markets` — NEVER a token symbol or address.
- amountstringbodyrequired
  Amount to simulate ("max" for repay/withdraw/withdraw_collateral only) as a decimal string in HUMAN units, or "max" for the full balance/debt.
POST/mcp/build_lend
via Yeetful (free)morpho-mcp.yeetful.com
Prepare transactions to lend an asset into a Morpho market and start earning the supply APY — returns UNSIGNED {action:'send_transaction'} steps (exact-amount approve first when allowance is short) for the USER to sign. Get the 32-byte marketId from `markets` first — the param validates a MARKET ID, not a symbol.
4 parameters

  EVM address (0x…) of the wallet that lends and signs — pass "$USER_ADDRESS" for the connected user.
- chainIdnumberbody
  Chain id: 8453 = Base (default), 1 = Ethereum mainnet. Market ids are chain-specific — use the chainId the market came from.
