"Using Google Calendar to query and create events" matching MCP servers:

A Model Context Protocol server providing tools for querying Bitcoin blockchain data via Blockchain Data and Query APIs, supporting various BTC information retrieval functions.

Exposes Base mainnet chain query tools over MCP, letting clients fetch an address's native balance and current gas fee estimates (slow/standard/fast urgency) from an upstream HTTP API. Paid tools are gated by x402 micropayments settled through the CDP facilitator, with a free health check and a documented free-trial allotment.

This MCP wraps Bitrefill public API to allow agents to search for products and shop using cryptocurrencies like Bitcoin, Ethereum, Solana, and many more.
