"Elastic Stack" matching MCP servers:

MCP server for eBay buyer-side workflows enabling search, watch, bid, buy, and management of MyeBay via a hybrid REST and Trading API stack.

MCP server exposing a Lightning wallet to LLM agents over Nostr Wallet Connect (NIP-47): balance, invoices, LN address/LNURL payments, batch pay, and keysend. All spend tools are wrapped in a defense-in-depth safety stack — budget caps, allowlist, two-step confirmation, audit log.

Provides real-time stock quotes including price, change, volume, market cap, and company name for major US and international exchanges, with pay-per-call access via x402 micropayments and no API key or signup required.

Deploy and monetize agent-built apps from one MCP. Ship a full-stack app (login, database, usage billing) with one command, then charge the signed-in end user per API call via X-Settle-Payer (end-user-pays: cost times markup, app owner earns the markup).

MCP server that gives terminal AI agents a guarded USDC wallet with firewall, automatic 402 payment handling, and budget limits.

Enables human-in-the-loop authorization for AI agent transactions, allowing real-time approval or denial of purchases based on configurable spending limits, vendor blocklists, daily caps, and category restrictions.

A local MCP server that helps the Payments team by querying microservice specs, payment flows, triaging CS tickets with GCP analysis, and calling Stark Bank APIs in development/sandbox environments.

MCP server for investigating payment/webhook drift, classifying order status mismatches, detecting duplicate charges, and escalating findings for human review. It is read-only for payment state and does not automatically retry or correct transactions.
