### Description (declared)

# trading-position-risk-mcp

> **Not financial advice. Use at your own risk.** This is a guardrail that enforces rules *you* configure.
> It cannot see your broker, does not place orders, and trusts what the agent reports. It can be wrong,
> and trading can lose money. Test with paper trading first. See [Security and trust model](#security-and-trust-model).

A deterministic position-sizing and pre-trade risk server for trading agents, served over MCP.

Agents never do sizing math themselves. They ask this server. It applies a rulebook that the human
owns, and it answers **APPROVED / RESIZED / REJECTED** with the rules that fired and an approval token.

The core formula reproduces the *E-Mini (ES) Position Sizing Calculator v4.5* spreadsheet exactly
(`floor(equity × risk% ÷ (stop points × point value))`). On top of that it adds costs, micro
fallback, portfolio heat, exposure buckets, a daily-loss lockout, drawdown tiers and options.

## Quick start

Requires **Python 3.11+**. The easiest way to run the commands is `uvx` or `pipx`:

```bash
uvx --python 3.11 --from trading-position-risk-mcp position-risk-admin show
```

First run: the server starts with the `starting_equity` in `rules.yaml` ($55,000 by default). Enter your
real account size once, before any agent trades:

```bash
position-risk-admin set-equity 25000 --note "initial"
```

```bash
pip install -e ".[dev]"
pytest                                   # 190+ tests, including spreadsheet parity
position-risk-mcp                        # stdio MCP server
position-risk-mcp --http 8765            # streamable HTTP instead (loopback only; see Security)
position-risk-admin size ES long 6500 6498 --no-costs    # same answer as the sheet: 5 contracts
```
