Marketplace MCP server

What it does

GateCore is a governed transaction layer for AI agents that exposes a marketplace of capabilities with machine-readable pricing, scope, and trust terms. It provides discovery of listings, contract inspection, procurement decisions with signed receipts, and audit trails for agent transactions.

• Discover available AI capabilities with published prices and required permissions before committing to a transaction.
• Evaluate capability contracts programmatically by reading machine-readable terms including price, required scopes, and minimum trust thresholds.
• Request and track governed procurement decisions with tamper-evident receipts that bind requests, policy decisions, and settlements.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
