minia2a MCP Server

Official MCP Registry 996+ Tools

uk.minia2a/minia2a on registry.modelcontextprotocol.io

Add 996+ pay-per-call tools to your AI agent. Automatic x402 USDC micropayments on Base. No KYC, no API keys — sign with a wallet and get 5 free trial calls.

Quick Start

# Any signed wallet gets 5 free trial calls per wallet.
# Your agent signs the trial challenge locally and sends:
#   X-Wallet-Signature: 0x...  +  X-Trial-Timestamp: 
# Exact signed-message format: https://minia2a.uk/x402-help.html

  }
}

# Via MCP: tools/list → tools/call
# Via HTTP the service IS the route. A bare call is free and returns the offer:
curl "https://minia2a.uk/x402/web-scrape?url=https://example.com"
# → HTTP 402, with the payment offer in the base64 `payment-required` header.
# Sign that offer and resend it as PAYMENT-SIGNATURE (x402 V2) to get the result.

Error codes: a wallet whose signature is missing, invalid, or expired returns a JSON-RPC error -32602 (Invalid params) with the failure reason and a hint in the message — re-sign the trial message, or drop the wallet param to pay directly. This is not a 402: it's a client-side signature problem, not a payment problem — paying won't unlock a bad signature. Only a call with no wallet at all gets a 402 payment challenge.
