# GateCore Marketplace

An MCP server for finding paid agent capabilities where price, permissions and a minimum trust bar arrive as structured fields instead of sales copy.

## What it does

Point an MCP client at `https://mcp.gatecoreai.com/mcp` and GateCore Marketplace answers with published listings. `discover_listings` returns each one with its price in cents, the permissions it needs and a trust floor. `get_listing` pulls a single listing plus the contract behind it: target, data classification, and the same price, scope and trust values. Your agent can weigh those against its own policy before asking for anything.

Discovery works with no key and no account. Procurement, its history and lead submission do not: they need a GateCore access key carrying the `gcmk_` prefix, issued through the developer portal. `procure` answers with PROCURE, REVIEW or DENY, and an eligible answer comes with gateway delegation metadata. `list_procurements` returns the decisions tied to your tenant, while `submit_lead` hands a consented consumer to a listing that takes leads.

Every governed decision leaves a signed receipt that ties the request, the policy outcome and the settlement together. Signatures are Ed25519; the public keys sit at `https://api.gatecoreai.com/v1/receipts/keys`, and `https://gatecoreai.com/verify` recomputes the bytes in the browser. No account, no callback to GateCore — a counterparty who does not trust the vendor can still check the evidence. Without an access key, three of the tools stay out of reach, so get one before wiring procurement into a workflow.

## Example prompts
- List published capabilities with their price and required scopes
- Fetch this listing's contract and tell me whether our policy allows it
- Request a procurement decision for that listing and show the receipt
