morpho-cli（morpho CLI 命令行）

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@latest <command> [options]

Supported chains: ethereum, base, arbitrum, optimism, polygon, unichain, worldchain, katana, hyperevm, monad, stable. Every command requires --chain.

Response Schemas

• Read commands — exact JSON shapes for query-vaults, get-vault, query-markets, get-market, get-positions, get-token-balance, health-check, get-supported-chains
• Write commands — exact JSON shapes for prepare-* and simulate-transactions

Write Workflow: Prepare → Present

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

1. Prepare — run a prepare-* command. The CLI handles token decimals, allowances, approvals, and simulation automatically. Returns a flat PreparedOperation with the fields you need at the root: operation, summary, requirements (informational — approval txs are already in transactions), transactions (the unsigned payloads to sign), simulated, simulationOk, totalGasUsed, outcome, warnings. Pass --no-simulate to skip simulation (in which case simulationOk, totalGasUsed, and most of outcome will be absent).
2. Present — show summary, the transactions list, the key outcome fields (see table below), and any warnings in tabular format. If simulationOk is false, inspect revertReason before presenting.

The outcome block is discriminated by operation type:

Use simulate-transactions separately only for re-simulating with different parameters or simulating arbitrary transactions. Its top-level success field is allSucceeded (not simulationOk) — see references/write.md.

Simulation Failures

Partial Withdrawal

When prepare-withdraw --amount max cannot withdraw the full balance, the CLI returns a PreparedOperation whose warnings[] calls out the liquidity shortfall. The response is still valid — it represents the largest withdrawable amount right now.

1. Surface the warning to the user verbatim — do not silently accept a smaller withdrawal.
2. Offer two paths:

- Accept the partial amount the CLI prepared (inspect outcome.vault.assetsReceived for the concrete figure, optionally re-run prepare-withdraw with --amount <value> using ~99% of that figure as a safety buffer against interest accrual between prepare and execute). - Wait for more liquidity — locked assets unlock as underlying-market borrowers repay or the curator reallocates.

1. Never invent an amount by parsing the summary string — it is a human sentence, not a machine-readable field.

Safety Rules

1. Check simulation before presenting — simulation runs by default; check simulationOk (for prepare-*) or allSucceeded (for simulate-transactions) before presenting
2. Never sign or broadcast — unsigned payloads only
3. Watch health factor for borrows — warn if below 1.1
4. Communicate liquidity constraints clearly for partial withdrawals

CLI Errors

When a npx @morpho-org/cli@latest 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)
• Dividing TokenAmount.value by 10^decimals — TokenAmount values are already decimal-applied (a USDC value of "1000" means $1,000, not 1,000 micro-USDC). *Pct fields are already percent-scaled; *Usd fields are already in dollars. The only raw integer strings are inside outcome.market.{supplied,borrowed,collateral} and outcome.vault.{sharesReceived,assetsReceived,positionShares} — those do need /10^decimals for display.
• Assuming 18 decimals — USDC/USDT have 6, WBTC/cbBTC have 8. Read decimals from response metadata; never assume.
• 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 simulationOk === false on prepare-* (or allSucceeded === false on simulate-transactions) — diagnose before presenting
