**4 tools: 1 do something that can't be undone, 1 change things and 2 only read.**

## Findings

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

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

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The input addresses people (input.recipient): what it sends cannot be taken back.
```


## Can't be undone (1)

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

### `prepare_quote`

- The input addresses people (input.recipient): what it sends 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
Prepare an on-chain BlazePhoenix quote to run on YOUR OWN RPC. Returns the exact eth_call (Quoter address + calldata, as a ready JSON-RPC request and a curl line) plus a `request` object. Run the call on your node, then pass `request` and the result hex to decode_quote. This server performs no RPC.
```

## Changes things (1)

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

### `decode_quote`

- 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
Decode the eth_call result YOUR node returned for a prepare_quote call: net output after the 0.28% fee, the minimum the Router enforces on-chain, price impact, the Phoenix Check verdict (ok / caution / danger / blocked — fails closed) and, with a recipient, verified unsigned calldata. Pure computation.
```

## Only reads (2)

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

### `get_abi`

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

Description, as the server wrote it:

```untrusted-server-text
The JSON ABI of one BlazePhoenix contract, generated from the Solidity sources, with the source revision it was built from. Use it to encode your own calls to the addresses get_deployments returns, or pass `errors` to decode a revert reason from a failed swap or quote. Returns { contract, revision, abi }; an unknown name returns ok:false with the accepted list. Pure lookup, no RPC.
```

### `get_deployments`

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

Description, as the server wrote it:

```untrusted-server-text
The versioned BlazePhoenix deployment registry: Core, Hub, Solver, Quoter and Router addresses per chain and protocol version (1.0.0 live; 2.0.0 the final generation), and which version each chain runs now.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `blazephoenix`:

```json
{
  "permissions": {
    "allow": [
      "mcp__blazephoenix__get_deployments",
      "mcp__blazephoenix__get_abi"
    ],
    "ask": [
      "mcp__blazephoenix__prepare_quote",
      "mcp__blazephoenix__decode_quote"
    ],
    "deny": []
  }
}
```
