## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_any_contract`

- 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
Free preview for ANY verified EVM contract on base, ethereum or polygon — including addresses not in the registry. Returns contract type, verification, name, whether it is a proxy, how many powers were found, how many owner-only functions went uncategorised, and whether an owner was found. The decision fields (which powers, the evidence, the admin address, the implementation) are withheld and listed by name. Use get_contract_powers first if the contract is already in the registry — that is free and complete.
```

### `recent_power_changes`

- 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
What actually changed behind the watched contracts: implementation swapped, owner moved, a power appeared or disappeared, verification lost. Each event carries the before and after value and the window it was detected in. Severity is one of critical / material / low. Use this to answer "has anything changed behind this contract recently?".
```

## Only reads (2)

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

### `get_contract_powers`

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

Description, as the server wrote it:

```untrusted-server-text
Full free analysis of one contract that is in the registry: verification, proxy pattern and implementation address, who the admin is and whether it is a single key, every retained power (upgrade / mint / grant-minter / pause / blacklist / seize / fees / sweep / burn-from / ownership transfer / limits) with the evidence and confidence behind it, reachable DELEGATECALL / SELFDESTRUCT / CREATE2 opcodes, and the owner-only functions the classifier could NOT categorise — which is where the unusual powers hide. Accepts an address or a symbol such as USDC or AERO.
```

### `list_watched_contracts`

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

Description, as the server wrote it:

```untrusted-server-text
List the EVM contracts in the Contract Powers registry, with a one-line risk shape for each: is the code upgradeable, is the admin a single key (EOA) rather than a contract, how many powers are declared, and is it covered by a bug bounty. Use this to see what is already analysed before spending a lookup. Filters are optional and combine with AND.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `contract-powers`:

```json
{
  "permissions": {
    "allow": [
      "mcp__contract-powers__list_watched_contracts",
      "mcp__contract-powers__get_contract_powers"
    ],
    "ask": [
      "mcp__contract-powers__check_any_contract",
      "mcp__contract-powers__recent_power_changes"
    ],
    "deny": []
