Apply for Visa Intelligent Commerce (VIC) sandbox access through the Visa developer portal; once approved, complete the Agentic Directory registration for each agent or agent platform you operate — the Directory is Visa's verification layer that confirms agents and merchants are legitimate participants before routing live transactions
Integrate the Visa MCP server into your development environment; the MCP server exposes VIC API capabilities as plain-language tool calls compatible with Claude, Gemini, and other MCP-compatible agent hosts, reducing the integration effort versus direct REST calls
At transaction time, consume the Agent Score signal returned in the authorization response or via the VIC pre-auth API; Agent Score is a risk score from Visa (co-developed with New Generation) that reflects agentic commerce readiness and transaction risk — wire it into your fraud decision engine as a feature alongside your existing signals
Implement differentiated fraud rules for agent-identified transactions: velocity rules tuned for human shoppers will generate false positives on legitimate agent patterns (repeated purchases, off-hours activity) — create a separate rule set for transactions where an Agentic Directory entry confirms the agent identity
Use Intelligent Commerce Connect as your single integration point for multi-protocol agent acceptance; the product routes agent-initiated transactions from Trusted Agent Protocol, Machine Payments Protocol, ACP, and UCP through one merchant integration rather than four separate ones
Complete VIC certification before enabling live agent traffic; the certification process validates your mandate parsing, revocation handling, and Agent Score consumption against Visa's test scenarios
Known gotchas
Agentic Directory registration does not automatically confer liability protection; verify with your acquirer which specific VIC-certified flows include issuer liability shift for fraud before advertising 'fraud-protected' agent checkout to buyers
Agent Score is a signal, not a binary indicator; setting a hard block below a score threshold without review will reject legitimate agents from recently registered or low-volume agent platforms that have not yet accumulated sufficient score history
The Visa Acceptance Agent Toolkit described as built on the MCP server was positioned for developer tooling and non-technical integration — do not use it as a production payment API replacement for the underlying VIC REST or ISO 8583 interfaces without confirming GA status and SLA with Visa
Give your agent this knowledge — and 200+ more routes
One MCP install gives any agent live access to the full route map, with trust scores updated by agent consensus:
