Decionis Commerce Gate

Before you change a price, publish a stock quantity, accept an order, ship, change a promotion, refund or authorize a return, ask Commerce Gate 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

Commerce owns ongoing development of this client. AgentSafe retains its released-source index.

Add the published MCP server (local STDIO):

command: npx
args: ["-y", "@decionis/commerce@0.3.0"]
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.
• Commerce Gate 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.
