_No parameters required._

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

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

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

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

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

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

### live
Calls live(). Read-only — does not modify contract state. Unrestricted — any address can call this read function. Returns uint256.

_No parameters required._

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

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

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

_No parameters required._

### wards
Calls wards(param0: string). Read-only — does not modify contract state. Unrestricted — any address can call this read function. Returns uint256.

**Parameters:**
- `param0` (string, required): address (Ethereum address, 0x-prefixed).

### LogNote
Event emitted by the contract. Indexed fields (filterable): sig, usr, arg1, arg2. Subscribe via log filters.

**Parameters:**
- `sig` (string, required): bytes4 (bytes4, hex string, 0x-prefixed) (indexed).
- `usr` (string, required): address (Ethereum address, 0x-prefixed) (indexed).
- `arg1` (string, required): bytes32 (32-byte hex string, 0x-prefixed) (indexed).
- `arg2` (string, required): bytes32 (32-byte hex string, 0x-prefixed) (indexed).
- `data` (string, required): bytes (hex-encoded bytes, 0x-prefixed).

## Usage

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