Paid MCP for AI agents

Verify a vendor before an agent pays.

AgentKYB turns legal-entity evidence, sanctions signals and domain evidence into an explicit allow, review or block preflight before an AI agent pays.

One preflight, four evidence layers.

Designed for procurement, vendor onboarding, marketplace payouts and autonomous-payment workflows where an agent needs evidence before sending funds.

01Entity resolution

Resolve a supplied business name against available registry evidence and jurisdiction context.

02Sanctions signals

Screen potential name matches against indexed official sanctions sources and flag them for review.

03Domain evidence

Inspect RDAP registration evidence when a vendor domain is supplied.

04Consistency signal

Compare the supplied company name and domain as one more evidence point before payment.

What an agent sends and receives.

The input is intentionally small. The output is machine-readable evidence, not a black-box approval.

Input
{
  "name": "Vendor or counterparty name",
  "country": "GB",
  "domain": "vendor.example"
}
Output
{
  "decision": {
    "action": "allow | review | block",
    "risk_score": 0,
    "evidence_confidence": 0
  },
  "company": { "...": "..." },
  "sanctions": { "...": "..." },
  "domain": { "...": "..." },
  "sources": ["..."]
}

How payment safety works.

01Call before payment

Your agent calls vendor_preflight before it creates or releases a vendor payment.

02Receive x402 terms

If no valid payment is attached, AgentKYB returns a Base USDC payment challenge for exactly 0.05 USDC.

03Apply the result

After settlement, use allow, review or block in your own payment policy. Review and block must stop automation.

Integration details.

Use the production endpoint below. It requires USDC on Base mainnet and supports x402 payment negotiation. A client must support both remote MCP and x402 payment.

Paid MCP endpoint
{
  "tool": "vendor_preflight",
  "input": {
    "name": "Revolut Ltd",
    "country": "GB",
    "domain": "revolut.com"
  },
  "payment": "x402 / exact / 0.05 USDC / Base"
}

Founding pilot for agent builders.

We are onboarding the first five external builders whose agents make supplier, marketplace, research, or autonomous-payment decisions.

  • Same public launch price: 0.05 USDC per completed result on Base.
  • No subscriptions, API keys, or free-report bypasses.
  • Priority feedback loop to improve the evidence your workflow needs.
Request the pilot

Share only a public project link and the non-sensitive workflow where evidence before payment would help. Never post wallet keys, vendor records, personal data, or confidential transaction details.

What AgentKYB does not do.

  • It does not approve a transaction, vendor or relationship.
  • It is not legal, compliance, credit or sanctions-clearance advice.
  • A potential sanctions name match needs additional identifiers and human or compliance review.
  • Registry and domain evidence can be incomplete, stale or unavailable for a jurisdiction.
Decision-support rule

Use the result as evidence within your own risk policy. For high-value, regulated or suspicious transactions, require independent verification and escalation.
