AsterPay MCP connector

Give Claude and other AI assistants four read-only AsterPay tools: agent trust scoring, USDC→EUR settlement estimates, crypto market rates, and merchant payment-endpoint resolution. No API key. Nothing moves money.

What it is

A hosted, remote MCP server at https://mcp-api.asterpay.io/mcp exposing AsterPay's public data as assistant tools. It is read-only and unauthenticated — there is no payment, budget, or money-movement capability here. (Those live in the separate @asterpay/mcp-server npm package for developers who wire up a wallet.)

Tools

check_agent_trust

Know Your Agent: trust score 0–100, tier (Open/Verified/Trusted/Enterprise) and components (ERC-8004 identity, sanctions screening, wallet age/activity) for an Ethereum address.

read-only

settlement_estimate

Estimate converting a USDC amount to EUR: exchange rate, AsterPay fee (0.5% + €0.10 on the EU rail), net EUR, and SEPA Instant timing. An estimate only — no payment is made.

read-only

market_rates

Current reference market rates AsterPay uses (e.g. USDC, EURC and major crypto rates). No input.

read-only

merchant_resolve

Resolve a European business to its verified payment endpoint (IBAN/BIC) from provable sources. By merchant id, or business id + type (vat, y_tunnus, company_number, lei, duns).

read-only

Connect it in Claude

From the Connectors Directory (once listed): open Claude → Connectors → find “AsterPay” → Connect. No credentials are required.

As a custom connector (available today): in Claude, add a custom connector with this URL:

https://mcp-api.asterpay.io/mcp

The transport is Streamable HTTP. There is no sign-in step — connect and the four tools appear.

Example prompts

  • “Use AsterPay to check the trust score of wallet 0xd5f8481D8F25d3966d2010DBf9B47fFbdf745A9E.”
  • “If an agent pays me 250 USDC, how much EUR lands in my bank after AsterPay's fee?”
  • “What are the current crypto market rates from AsterPay?”
  • “Resolve the AsterPay demo merchant (business_id_type: demo) and show its IBAN details.”

Privacy & data

The connector is stateless and collects no personal data: it forwards only the parameters you supply for a single request to AsterPay's public API and returns the result. It does not read your chat history, memory, or files. Full details are in the Privacy Policy (section 13) and Terms.
