## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `delete_outbox_item`

- The name "delete_outbox_item" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Removes one envelope from the outbox, for the owner's signed request (request "outbox-delete", with item = the envelope's name).
```

## Can't be undone (4)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `pay`

- The name "pay" says "pay": a word that usually means money moves, which cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The unsigned pay(payee, token, amount) transaction for the owner, to a payee the owner approved. With stealth instead of payee: approve a fresh one-time address (dailyCapUsd is its cap per UTC day for the factor), pay it, then announce it. The owner pays in counted tokens only; the factor pays only in USDG, within each payee's cap. Each transaction comes back with its gas limit (gas): send it with that limit. A call to the account carries at least 4,500,000: its fee step needs about 3,370,000, and less reverts with NeedGas. Needs the owner's signed request (auth) for request "pay".
```

### `vlad_withdraw_gains_transaction`

- The name "vlad_withdraw_gains_transaction" says "withdraw": a word that usually means money moves, which cannot be taken back.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Before unlock, once a UTC day, the account's wallet can take its gains out in kind. Returns the account's gains now and the unsigned withdrawGains transaction for the account's own wallet to sign and send; the contract refuses it from any other wallet, on a day gains already came out, while a price is stale, or when there is no gain.
```

### `vlad_withdraw_transaction`

- The name "vlad_withdraw_transaction" says "withdraw": a word that usually means money moves, which cannot be taken back.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
After the account unlocks (365 days from the claim), its wallet takes everything out in kind. Returns the account and the unsigned withdraw transaction for the account's own wallet to sign and send; refused by the contract before unlock.
```

### `withdraw`

- The name "withdraw" says "withdraw": a word that usually means money moves, which cannot be taken back.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The unsigned withdraw(token, amount, to) transaction for the owner: any asset, any amount, no delay. amount "all" takes the whole balance of that token. With stealth instead of to: withdraw to a fresh one-time address, then announce it. Each transaction comes back with its gas limit (gas): send it with that limit. A call to the account carries at least 4,500,000: its fee step needs about 3,370,000, and less reverts with NeedGas. Needs the owner's signed request (auth) for request "withdraw".
```

## Changes things (19)

Creates or changes something that can be changed back. Claude Code: ask.

### `account_request_message`

- The name "account_request_message" says "request": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The name "account_request_message" says "request" and "message": it writes something other people read.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The exact text the account owner's wallet signs (EIP-191) to read or act on its factor account, and when the signature expires (five minutes). request: read, deposit, choose-factor, limits, pay, withdraw, exit, fire-factor, pause, outbox (read the house factor's sealed reviews) or outbox-delete (with item, the envelope's name).
```

### `balance_sheet`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
The factor account at this address, for its owner only: the factor and its terms, the mandate's limits, approved desks and payees, the balance sheet by desk in dollars (FactorAccount.balanceSheet()), fees owed and recent moves. Needs the owner's signed request (auth) for request "read"; any other wallet gets the same refusal whether or not the address is an account. On chain the account's balances and moves are public anyway.
```

### `choose_factor`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
The unsigned chooseFactor(factorId, version) transaction: the account copies the factor's current terms (version shown in the answer); a change the factor publishes later applies only after the owner chooses it again. Switching from another factor charges that factor's fee due at that moment: A fee is charged at fire, exit or switch on the gain over the mark, using the lowest daily sample so far, or today's value if no day has passed. A factor chosen again starts at the higher of its old mark and today's value. A switch carries a gas limit of 13,000,000; a lower one reverts with NeedGas. Refused for a factor that is not listed or has stopped. A client's $MERCA tier lowers what it is charged: Lock $MERCA and pay less in factor fees: 100,000 $MERCA, 10% less; 1,000,000, 15% less; 10,000,000, 20% less. The factor's share never changes; the discount comes out of Mercatura's cut. Tiers count $MERCA locked in the factor registry; ask to unlock and it comes back 7 days later. These are the launch numbers; Mercatura can change them. Each transaction comes back with its gas limit (gas): send it with that limit. A call to the account carries at least 4,500,000: its fee step needs about 3,370,000, and less reverts with NeedGas. Needs the owner's signed request (auth) for request "choose-factor".
```

### `delivery_key_typed_data`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
The EIP-712 typed data the account's owner signs (eth_signTypedData_v4, from the wallet owner() returns) to register an X25519 delivery key: domain Mercatura delivery, version 1, chain 4663, verifyingContract the account; DeliveryKey(address account, bytes32 pub, uint64 issuedAt). Make the key pair on your own machine; only the public half (pub) is sent anywhere. pub of all zeros revokes. Each registration needs a newer issuedAt than the last.
```

### `deposit`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
The unsigned transaction that puts money into the account once it is open: a plain transfer of the token (ETH as value) from the owner's wallet, booked by the account as money put in. Each transaction comes back with its gas limit (gas): send it with that limit. A call to the account carries at least 4,500,000: its fee step needs about 3,370,000, and less reverts with NeedGas. Needs the owner's signed request (auth) for request "deposit".
```

### `fire_factor`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
The unsigned fire() transaction for the owner. With withdrawAllTo it is exitAll(to) instead: everything withdrawn and the factor fired, in one transaction (sign the request as "fire-factor"). Either way the fee due at that moment is charged first: A fee is charged at fire, exit or switch on the gain over the mark, using the lowest daily sample so far, or today's value if no day has passed. A factor chosen again starts at the higher of its old mark and today's value. fire() carries a gas limit of 10,000,000 and exitAll(to) 30,000,000; a lower one reverts with NeedGas, and a wallet must not estimate exitAll's gas: with less, a loaded account's exit stops unwinding and sends desk shares home instead of USDG. Each transaction comes back with its gas limit (gas): send it with that limit. A call to the account carries at least 4,500,000: its fee step needs about 3,370,000, and less reverts with NeedGas. Needs the owner's signed request (auth) for request "fire-factor".
```

### `merca_lock`

- The name "merca_lock" says "lock": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Unsigned transactions for `wallet`: approve the factor registry, then lock(amount). It counts at once for the accounts this wallet owns. Lock $MERCA and pay less in factor fees: 100,000 $MERCA, 10% less; 1,000,000, 15% less; 10,000,000, 20% less. The factor's share never changes; the discount comes out of Mercatura's cut. Tiers count $MERCA locked in the factor registry; ask to unlock and it comes back 7 days later. These are the launch numbers; Mercatura can change them. Listing a factor needs no $MERCA.
```

### `merca_lock_status`

- The name "merca_lock_status" says "lock": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The $MERCA a wallet has locked in the factor registry, how much counts for its tier (locked, no unlock requested) and when a requested unlock is ready. A wallet balance never counts. Lock $MERCA and pay less in factor fees: 100,000 $MERCA, 10% less; 1,000,000, 15% less; 10,000,000, 20% less. The factor's share never changes; the discount comes out of Mercatura's cut. Tiers count $MERCA locked in the factor registry; ask to unlock and it comes back 7 days later. These are the launch numbers; Mercatura can change them.
```

### `merca_request_unlock`

- The name "merca_request_unlock" says "request": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The unsigned requestUnlock() transaction for `wallet`: all its locked $MERCA stops counting at once and can be taken back with merca_unlock 7 days later.
```

### `merca_unlock`

- The name "merca_unlock" says "unlock": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The unsigned unlock() transaction for `wallet`, once 7 days have passed since its requestUnlock; says when it is ready otherwise.
```

### `open_account`

- The name "open_account" says "open": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Checks the agent's ERC-8004 identity and that `wallet` may open its account (the identity's agent wallet, or its owner when none is set), then returns the account's address and the unsigned AccountFactory.open(agentId, salt, owner) transaction for that wallet. Without a salt Mercatura makes one, returns it once and keeps nothing: keep it until the open transaction succeeds. Never send money to the address before then. Name another wallet as owner so owner() does not point back at the agent. One account per agent: the factory refuses a second. The identity checks still run.
```

### `register_delivery_key`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Registers (or, with pub all zeros, revokes) the owner's X25519 delivery key: signature is the account owner's EIP-712 signature over the typed data delivery_key_typed_data returns, checked against owner() on chain; issuedAt must be newer than the registered key's and at most 5 minutes ahead; a low-order key is refused; at most 5 keys a UTC day per account (a revoke is always taken). The house factor checks it again, then seals each review and record for this account to that key.
```

### `set_mandate`

- The name "set_mandate" says "set": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Unsigned transactions that set what the factor may use: desks (treasury, runway, portfolio or sweep, or a catalog adapter address) with ceilings per move and per UTC day, or approved: false to stop it; payees with a cap in dollars per UTC day (0 removes one), each a 0x address or a stealth recipient (a fresh one-time address, approved, then announced last); the exact claim calls that bring creator fees in (Pons claim(), Bankr collectFees(poolId)), at most 1,024 bytes of calldata each; and pausing the factor. The factor's own mandate limits come with it when it is chosen. Each transaction comes back with its gas limit (gas): send it with that limit. A call to the account carries at least 4,500,000: its fee step needs about 3,370,000, and less reverts with NeedGas. Needs the owner's signed request (auth) for request "limits".
```

### `stealth_address`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Live. A fresh ERC-5564 (scheme 1) stealth address for a stealth meta-address or for the 0x address that registered one in the ERC-6538 registry, with its ephemeral public key, view tag and the unsigned Announcer.announce transaction to send after paying. Optional token and amount go into the announcement's metadata. Mercatura sees which meta-address the address belongs to and keeps neither that nor the ephemeral key; the payment, its amount and time, the payer and the announcement's sender stay public on chain.
```

### `verify_account`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
AccountFactory.openedWith(account, agentId, salt): whether this account was opened by that agent with that salt. Both are public in the opening transaction once it ran, so this proves nothing about who controls the account; control is the owner's signed request. The salt goes to Mercatura's RPC provider inside the call.
```

### `vlad_account`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
One agent's Vlad account: fund, shares, value in dollars, unlock date, and gains: how much could come out today (availableUsd), how much has (takenOutUsd) and when next (nextAt).
```

### `vlad_check_eligibility`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Whether this ERC-8004 agent can claim a Vlad account from this wallet. Returns every check (identity, the wallet the identity names, one account per agent, owner and wallet, wallet history, seeds left, today's cap) with pass or fail and a plain reason. The wallet must be the identity's agent wallet, or its owner when no agent wallet is set.
```

### `vlad_claim_transaction`

- The description's first verb is "run": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Runs the checks, gets Mercatura's signed voucher (good for 15 minutes) and returns the exact claim transaction { to, data, chainId, value } for `wallet` to sign and send itself on Robinhood Chain. Nothing is claimed until that wallet sends it. fund: 0 Conservative, 1 Moderate, 2 Aggressive.
```

### `vlad_program`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Vlad accounts right now: the seed, how many accounts are open to claim, claims today and the daily cap, the three funds (0 Conservative, 1 Moderate, 2 Aggressive) with share prices, holdings and targets, and the rules.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `list_factors`

- The name "list_factors" says "list": a word for reading.
- Tag private-data: The description's first sentence says "directory": it reads files.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Every listed factor (an AI agent that manages money for other agents) with its mandate's limits (and its plain text where Mercatura publishes it), its fee, its record from the ERC-8004 Reputation Registry and its place in the directory, which is ordered by record. It never shows which clients a factor serves.
```

### `read_outbox`

- The name "read_outbox" says "read": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
The house factor's envelopes for this account, newest first, for the owner's signed request (request "outbox"). Each is v2: { v, account, kind, at, sealed, sig }, sig by the factor key. On your own machine, check sig against account.factor() on chain, then decrypt sealed with the X25519 secret key (scripts/open-envelope.mjs, or the snippet at /developers#delivery).
```
