First indexed and scored.

## MCP tools (6)

### `load_code` (~101 tokens)

Reset the debugger and load new Brainfuck source code.

Input parameters:

- `code` (string, required)
- `initial_input` (string)
- `maxValue` (number): Maximum allowed value for tape cells (default: 9007199254740991)
- `minValue` (number): Minimum allowed value for tape cells (default: -9007199254740991)
- `tapeSize` (integer): Size of the memory tape (default: 30000)

### `step` (~34 tokens)

Execute a specific number of instructions (default 1). Then outputs the summary of the current state.

Input parameters:

- `count` (number)

### `run` (~54 tokens)

Run the program until it finishes or waits for input. Infinite loops WILL hang the server. Then outputs the summary of the current state.

Input parameters:

- `limit` (number): Optional limit if you still want one. Omit to run forever.

### `add_input` (~35 tokens)

Append characters to input buffer. Use when status is WAITING_FOR_INPUT. Outputs the engine status.

Input parameters:

- `input` (string, required)

### `get_state` (~60 tokens)

Get the current full state (memory, pointers, output). When windowRadius is not specified, returns the entire tape which may be a large amount of data.

Input parameters:

- `windowRadius` (number): Optional radius around data pointer. When omitted, returns entire tape.

### `read_output` (~17 tokens)

Get the full output string generated so far.
