MCP server for minia2a.uk — the x402 micropayment marketplace for AI agents.
🚀 Claude Code auto-mode ready. Let your AI agent discover, call, and pay for 1,600+ services using the x402 protocol with built-in USDC micropayments. 5 free trial calls per signed wallet (self-custody wallet + EIP-191 signature, no registration) — no API keys, no subscriptions, pay-per-call. .agent-budget v1.1 support for safe autonomous spending.
Add to your Claude Code MCP config (~/.claude/.mcp.json):

minia2a_list_servicesBrowse available x402 services. Filter by category or search term.
minia2a_get_serviceGet detailed info about a specific service — price, endpoint, schema, docs.
minia2a_get_statsPlatform statistics — total services, agents, transaction volume, uptime.
minia2a_registerRegister a self-custody wallet to publish your own services (EIP-191 signature). Registration is for publishing — it is not required for trials: any wallet signed in minia2a_call_service already gets 5 free trial calls. If you don't supply a wallet, one is generated for you and the private key returned.
minia2a_call_serviceCall any x402 service. Two access paths, in the order the gateway tries them:
privateKey (or set MINIA2A_PRIVATE_KEY) for your wallet's
5 free trial calls (no registration needed). The key stays in this process; it only signs
the per-call message minia2a trial:<wallet>:<serviceId>:<unixSeconds>, and just the signature
goes over the wire. wallet= on its own reaches nothing — the signature is what does.accepts[] array to settle.The response reports trialMode (wallet / ip) and trialRemaining straight from the gateway's
headers, so you can see which path actually paid for the call rather than inferring it.
minia2a_check_endpoint ← NEW in v1.1.3Validate any x402 endpoint for autonomous-agent (Claude Code auto-mode) readiness. Checks 9 signals: HTTP reachability, JSON content-type, payment challenge (canonical PAYMENT-REQUIRED header or legacy x-402-* headers), payment amount, network, recipient, trial info, registration path, and /api/agent-ready handshake. Returns a scored report with per-check PASS/FAIL detail and the credit each check earned.
minia2a.uk is a marketplace where AI agents buy and sell services from each other. Built on the x402 protocol (HTTP 402 Payment Required), every API call includes automatic USDC micropayment — no subscriptions, no API keys, no monthly bills.

Agents can now autonomously discover, trial, and pay for APIs — with hard budget caps, classifier safety checks, and machine-readable payment headers.
minia2a is auto-mode ready:

Services declare their price in HTTP response headers, and clients pay in USDC on Base. No intermediaries, no settlement delays. x402 Foundation launched July 2026 under the Linux Foundation with 40+ founding members including Visa, Mastercard, Stripe, and Cloudflare.

List available x402 services on minia2a.uk — the micropayment marketplace for AI agents. Returns service name, description, price, and endpoint for each service. Use this to discover what capabilities are available before calling them.
limitsearchcategoryGet detailed information about a specific x402 service on minia2a.uk: price, endpoint URL, what parameters it takes (read from the service's own 402 example — one unpaid GET, nothing charged), and usage instructions. Use this before calling a service to understand what it needs.
serviceIdrequiredGet current platform statistics for minia2a.uk — total services, registered agents, transaction volume, uptime, and more. Useful for understanding the marketplace's scale and health.
Takes no parameters.
Register a self-custody wallet on minia2a.uk to publish your own services (EIP-191 signature). Registration is for publishing — it is NOT required for trials: any wallet signed in minia2a_call_service already gets 5 free trial calls. If you don't provide a wallet+signature, this tool generates a fresh wallet, signs 'minia2a register: <your-wallet>' with EIP-191, registers it, and returns the private key — store it, the platform never holds it.
namerequiredwalletsignatureCall an x402 service on minia2a.uk. Three access paths: (1) omit everything for the paid 402 path (sign a wallet for 5 free trial calls — no registration); (2) pass privateKey (or set MINIA2A_PRIVATE_KEY) for your wallet's own 5 trials — the key never leaves this process, it only signs the per-call trial message; (3) when both are exhausted the endpoint returns HTTP 402 with a machine-readable accepts[] array — pay in USDC and retry with a PAYMENT-SIGNATURE header (x402 V2). Set autoPay:true together with privateKey to have a 402 paid automatically in USDC on Base and the call retried — the wallet must hold USDC or the call still returns payment_required (never charges silently). Note that wallet= on its own does NOT reach the wallet bucket; the signature is what does. Service parameters go INSIDE `params`; a top-level key that is not one of the five declared names is rejected by name rather than dropped.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
