# Decionis CommerceGate

Before you change a price, publish a stock quantity, accept an order, ship, change a promotion, refund or authorize a return, ask CommerceGate whether the action clears policy. It answers PROCEED, HOLD or BLOCK with the margin, stock or refund math and records a signed Decision Dossier.

## Setup

Add the MCP server (local STDIO):

    command: npx
    args: ["-y", "@decionis/commerce@0.1.3"]
    env: DECIONIS_API_KEY (secret), DECIONIS_ORG_ID, DECIONIS_API_BASE (optional)

Run `commercegate_describe_capabilities` first; it works without credentials.

## Rules

- Call `commercegate_evaluate_action` before the commerce action, with the exact facts (SKU, current and new price or quantity, landed cost, order amounts, refund amount).
- PROCEED is a policy result, not permission: the merchant's own tool or a person still performs the action.
- Stop on HOLD, BLOCK, an error or an ambiguous answer and show the reason to the operator.
- CommerceGate never writes to a marketplace or ERP. Do not route around it with another tool.
- For a Business Central transaction, use `commercegate_validate_erp_transaction`; ALLOW or BLOCK is enforced there.
- When finance asks why, fetch the dossier with `commercegate_get_dossier` or `commercegate_get_proof_packet`.
