- `duration` (string, required): uint256 (uint256, pass as decimal string).

### reverseRegistrar
Calls reverseRegistrar(). Read-only — does not modify contract state. Unrestricted — any address can call this read function. Returns address.

_No parameters required._

### supportsInterface
Calls supportsInterface(interfaceID: string). Read-only — does not modify contract state. Unrestricted — any address can call this read function. Returns bool.

**Parameters:**
- `interfaceID` (string, required): bytes4 (bytes4, hex string, 0x-prefixed).

### valid
Calls valid(name: string). Read-only — does not modify contract state. Unrestricted — any address can call this read function. Returns bool.

**Parameters:**
- `name` (string, required): string.

## Write

### commit
Calls commit(commitment: string). Write function — may have access control restrictions (e.g. onlyOwner). Check contract source for modifier requirements before calling. No return value.

**Parameters:**
- `commitment` (string, required): bytes32 (32-byte hex string, 0x-prefixed).

### recoverFunds
Calls recoverFunds(_token: string, _to: string, _amount: string). Write function — may have access control restrictions (e.g. onlyOwner). Check contract source for modifier requirements before calling. No return value.

**Parameters:**
- `_token` (string, required): address (Ethereum address, 0x-prefixed).
- `_to` (string, required): address (Ethereum address, 0x-prefixed).
- `_amount` (string, required): uint256 (uint256, pass as decimal string).

### register
Calls register(name: string, owner: string, duration: string, secret: string, resolver: string, data: string[], reverseRecord: boolean, ownerControlledFuses: string). Requires ETH value to be sent with the transaction. Write function — may have access control restrictions (e.g. onlyOwner). Check contract source for modifier requirements before calling. No return value.

**Parameters:**
- `name` (string, required): string.
- `owner` (string, required): address (Ethereum address, 0x-prefixed).
- `duration` (string, required): uint256 (uint256, pass as decimal string).
- `secret` (string, required): bytes32 (32-byte hex string, 0x-prefixed).
- `resolver` (string, required): address (Ethereum address, 0x-prefixed).
- `data` (array, required): bytes[] (hex-encoded bytes, 0x-prefixed).
- `reverseRecord` (boolean, required): bool.
- `ownerControlledFuses` (string, required): uint16 (uint16, pass as decimal string).

### renew
Calls renew(name: string, duration: string). Requires ETH value to be sent with the transaction. Write function — may have access control restrictions (e.g. onlyOwner). Check contract source for modifier requirements before calling. No return value.

**Parameters:**
- `name` (string, required): string.
- `duration` (string, required): uint256 (uint256, pass as decimal string).

### renounceOwnership
Calls renounceOwnership(). Restricted: requires onlyOwner — only the owner address can call this. DANGER: Permanently and irreversibly removes all owner control from the contract. After calling, no address will ever be able to call onlyOwner functions again including adapter management, oracle configuration, emergency controls, and all set* functions. This action cannot be undone. No return value.

_No parameters required._

### transferOwnership
Calls transferOwnership(newOwner: string). Restricted: requires onlyOwner — only the owner address can call this. Transfers ownership to a new address. The new owner must call acceptOwnership() to complete the transfer (two-step pattern). No return value.

**Parameters:**
- `newOwner` (string, required): address (Ethereum address, 0x-prefixed).

### withdraw
Calls withdraw(). Unrestricted — any address can call this, but caller-specific logic may apply. Note: In vaults with async settlement, this queues a withdrawal request rather than transferring assets immediately. Assets are distributed when the settlement batch is processed (e.g. settleQueue). Returns a preview based on current NAV — actual payout depends on settlement NAV. No return value.

_No parameters required._

**Parameters:**
- `previousOwner` (string, required): address (Ethereum address, 0x-prefixed) (indexed).
- `newOwner` (string, required): address (Ethereum address, 0x-prefixed) (indexed).

## Usage

Connect to this MCP server at `https://ens.mcp.junct.dev/mcp`. All tools are callable via the MCP protocol.
Call `MIN_REGISTRATION_DURATION` first to query current state before any write operations.
Write operations like `commit` return data or calldata for agent use.
