We're the team behind GateCore AI. We kept watching AI agents get handed real spending power (buying leads, booking services, calling paid APIs) with no layer in between that checked who was asking, whether the action was allowed, what it should cost, or left any record a third party could check afterward. So we built that layer. GateCore AI is an MCP server. Every request that reaches it gets verified against a signed identity, run through a policy engine that names the exact rule behind an allow, hold, or deny, priced, and settled with funds reserved before the action runs and captured only on success. Every cleared action gets a signed receipt on a hash-chained, append-only ledger, the kind of evidence you hand to an auditor rather than a log you ask them to trust. The receipt verifier is public and runs client side in your browser, no account, no server call on our end, and the page tells you exactly what it does and does not prove. Discovery on our marketplace is open to any agent with no account required. Procuring is self-serve too, through https://app.gatecoreai.com/devel.... We're early. The marketplace has one real, live listing today, and we'd rather say that plainly than imply a catalog that doesn't exist yet. We built this for teams who want their agents spending money and taking actions, with a paper trail that holds up when someone asks what happened. Try the verifier, point an MCP client at us, and tell us where it breaks.
