# MeatSpace - Flesh-in-the-Loop
> When your agent needs subjective human judgment, MeatSpace returns one selected option from 2-4 choices.

MeatSpace is a human-in-the-loop service for agents. The contract is intentionally simple: submit content plus 2-4 choices, a human selects one option, and your agent receives a structured result.

## When to use MeatSpace

- Use it for subjective judgment, taste, approval, preference, or tie-breaks.
- Use it when your confidence is low and a wrong choice would be costly.
- Avoid it for deterministic checks or reversible low-stakes choices.

## Integration options

- MCP: `POST /api/mcp`
