## Findings

- **warn** Annotations that disagree with the tool in `how_to_pay` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "how_to_pay" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "how_to_pay" says "pay": a word that usually means money moves, which cannot be taken back.
```


## Deletes or cancels (2)

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

### `buy_token`

- The description's first verb is "execute": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Executes the buy. Called without xPayment it returns the HTTP 402 challenge, which is the correct first response and not an error. Called with a signed x402 payload in xPayment it settles on Base and the curve on the destination chain sends the tokens straight to `to`. You never need native gas on the destination chain and never need to bridge.
```

### `pay_and_buy`

- The name "pay_and_buy" says "pay": a word that usually means money moves, which cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Buys a market for real, completing the step an LLM cannot do alone: signing the EIP-3009 USDC authorisation. IMPORTANT for honest reporting — the signature is made by the operator's wallet on the server, not by a wallet you control, so describe the result as 'executed the purchase', not 'paid from my own funds'. Refuses unless the caller carries the agent key, and refuses any quote whose asset, network, recipient or amount does not match the hard-coded limits. Delivery always goes to the signer.
```

## Can't be undone (1)

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

### `how_to_pay`

- The name "how_to_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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The exact steps to turn a 402 challenge into a settled cross-chain buy: what to sign, which chain settles, and which header carries the payment. Free. Read this if you have never paid an x402 endpoint before.
```

## Changes things (8)

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

### `access_message`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Free. Returns the exact EIP-191 message an address signs (personal_sign) to prove it is the address asking. ask_agent accepts it for 10 minutes. Signing it moves nothing and costs nothing.
```

### `ask_agent`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Asks the market's own agent a question about that market. Open to an address whose stake in the market's stake contract is active (check_stake), proven with a signed access_message. The answer comes from glm-5.3 on the 0G router and is limited to facts read on-chain for this call; the tool returns those facts next to the answer. Refused without an active stake, and nothing is charged either way.
```

### `check_stake`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Free. Reads the market's stake contract on its own chain: its own AdextoAgentStake where it has one, otherwise the chain's AdextoStakeHub, which accepts every other market launched through ADEXTO from its first block. Returns how much an address has staked, the minimum, whether the position is active (at or above the minimum), and the totals. An active stake opens ask_agent for that market and an Agent Compute API key (see get_market staking.unlocks). There is no lock and no reward: unstake works at any time.
```

### `prepare_claim`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Unsigned transactions that collect the creator fee owed to an address across its markets: one claimCreatorFees() call per curve, or one Multicall3 batch per chain when several are owed. The curve always pays its immutable creator, whoever sends the transaction.
```

### `prepare_launch`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Launch a new ADEXTO market without handing over a key. Call it once without a signature: it checks the ticker, the chain and an optional ERC-8004 agent you own, and returns an attestation message for the deployer to sign (EIP-191). Call it again with the same arguments plus attestationMessage and attestationSignature: it anchors the launch metadata and returns the unsigned deployTrinity transaction (value 0, gas only), simulated from your address, with a gas estimate. Fee preset: 1.00% per trade, 0.70% to the creator. All supply goes into the curve; the creator gets no allocation. After the transaction is mined, call register_launch. The attestation message ends with an acceptance of the ADEXTO Terms and Acceptable Use Policy (adexto.xyz/terms): signing it is the deployer's acceptance, and markets that break the policy are removed from ADEXTO.
```

### `prepare_stake`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Unsigned transactions that stake a market's token in its stake contract or its chain's stake hub: an approval for the exact amount (only if the allowance is short), then the stake. Checks balance, minimum and hub eligibility first, so a stake that would revert is refused before any gas is spent. No lock: unstake works at any time. A stake opens ask_agent for that market.
```

### `register_launch`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
After the prepare_launch transaction is mined, lists the new market on adexto.xyz, in list_markets and on the x402 gateway. Reads the TrinityProjectDeployed event from the ADEXTO factory in the receipt; every value it registers comes from that event, not from the caller. Calling it again for the same transaction returns the existing listing.
```

### `trade_history`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Trade history for a market, newest first, with an explicit statement of whether it reaches the launch block. Free. Monad, Robinhood Chain and Arc are served by our Envio indexer and Base and Arbitrum One by our subgraph, both complete from the launch block; every market is also covered by our per-market index of every swap since launch, joined to a live log scan for the newest fills. When a market's index is still catching up or a read fails, the answer says so instead of presenting a shortened list as the whole history. Treasury buybacks are not trades and are not listed, although the curve's swapCount counts them.
```

## Only reads (3)

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

### `get_market`

- The name "get_market" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Full detail for a single market: chain, curve address, supply, fee rates, current price in the chain's native asset, and which read path serves its trade history. Free.
```

### `list_markets`

- The name "list_markets" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Every bonding-curve market this gateway can sell, across all chains it serves, with its ticker, chain, curve address and whether it is currently tradable. Free. Start here: the buy tools require a ticker and deliberately have no default.
```

### `quote_buy`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Reads the gateway's HTTP 402 challenge for a market and returns the quote and payment requirements without spending anything. The challenge carries the exact amount, the asset, the payTo address and the EIP-3009 domain, so an agent can decide before it signs. Free. This is the tool to call before buy_token.
```
