name: morpho-cli
description: Interact with the Morpho lending protocol using the CLI. Use this skill when the user asks to: query vault APYs, TVL, or allocation strategies ("What's the best USDC vault on Base?"); query market rates, utilization, or LLTV ("Show me ETH/USDC markets on Ethereum"); check user positions, balances, or health ("What are my Morpho positions?"); deposit into or withdraw from a vault ("Deposit 1000 USDC into Steakhouse vault"); supply collateral, borrow, or repay on a market ("Borrow 5000 USDC against my WETH"); prepare or simulate any Morpho transaction.

morpho-cli

Experimental (pre-v1.0) — Command syntax, response schemas, and available operations may change. Always verify critical outputs independently.

Query Morpho protocol data and build unsigned transactions. All commands output JSON to stdout. No private keys needed.

npx @morpho-org/cli <command> [options]

Supported chains: base, ethereum. Every command requires --chain.

Response Schemas

Read commands — exact JSON shapes for query-vaults, get-vault, query-markets, get-market, get-positions, get-position
Write commands — exact JSON shapes for prepare-*, simulate-transactions

Quick Reference

# Read — query protocol state

# Write — prepare unsigned transactions (simulation runs by default; add --no-simulate to skip)
npx @morpho-org/cli prepare-deposit              --chain base --vault-address 0x... --user-address 0x... --amount 1000
npx @morpho-org/cli prepare-withdraw             --chain base --vault-address 0x... --user-address 0x... --amount max
npx @morpho-org/cli prepare-supply               --chain base --market-id 0x... --user-address 0x... --amount 5000
npx @morpho-org/cli prepare-borrow               --chain base --market-id 0x... --user-address 0x... --borrow-amount 1

# Simulate — standalone re-simulation or arbitrary transaction simulation
npx @morpho-org/cli simulate-transactions --chain base --from 0x... --transactions '<JSON>' --analysis-context '<JSON>'

# Utility
npx @morpho-org/cli health-check
npx @morpho-org/cli get-supported-chains

Write Workflow: Prepare → Present

Every write operation follows two steps. Simulation runs automatically inside prepare-*.

Prepare — run a prepare-* command. The CLI handles token decimals, allowances, approvals, and simulation automatically. Returns {operation, simulation} where operation has transactions/summary/warnings/preview and simulation has execution results, gas, and post-state analysis. Use --no-simulate to skip simulation.
Present — show the summary, list of unsigned transactions, simulation results, and any warnings (low health factor, partial liquidity) in tabular format. If simulation.allSucceeded is false — diagnose before presenting.

Use simulate-transactions separately only for re-simulating with different parameters or simulating arbitrary transactions.

Simulation Failures

Revert	Cause	What to do
`ERC20: insufficient allowance`	Missing approval	Re-prepare — CLI should include approvals automatically
`ERC4626ExceededMaxWithdraw`	Vault liquidity insufficient	Reduce amount (see below)
`insufficient balance`	User lacks tokens	Tell the user
Custom error hex	Protocol-specific	Query state with `get-market` or `get-vault` to diagnose

Partial Withdrawal

If prepare-withdraw --amount max returns a liquidity warning:

Parse the safe amount from summary, apply ~1% buffer (parsedAmount * 0.99)
Re-call prepare-withdraw with the buffered amount, then simulate
Tell the user: remaining locked assets free up as borrowers repay

Safety Rules

Check simulation before presenting — simulation runs by default; check simulation.allSucceeded before presenting
Never sign or broadcast — unsigned payloads only
Watch health factor for borrows — warn if below 1.1
Communicate liquidity constraints clearly for partial withdrawals

CLI Errors

When a npx @morpho-org/cli command fails, stop and report the error to the user. Do not:

Retry with different parameters you invented
Fall back to alternative tools or APIs
Attempt to work around missing required options
Pipe output through jq or other filters — use the CLI's built-in flags (--fields, --sort-by, --limit, etc.) to shape the response

Common Mistakes

Forgetting --chain — every command requires it, there is no default
Using chain IDs (1, 8453) instead of names (ethereum, base)
Displaying raw amounts without dividing by 10^decimals — "2000000000" USDC is 2000, not 2 billion
Assuming 18 decimals — USDC/USDT have 6
Passing raw units as --amount — CLI expects human-readable (1000 not 1000000000)
Using --no-simulate without reason — simulation is on by default; only skip when debugging or for speed
Ignoring simulation.allSucceeded === false — diagnose before presenting
