"Information about MariaDB, an open-source relational database" matching MCP servers:

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

A Model Context Protocol server that gives an LLM read-only access to Binance spot market data, allowing models to reason about real prices without the ability to place orders.

An MCP server that provides tools for interacting with EDUCHAIN, allowing Claude to query information about tokens and pools and perform swaps through SailFish DEX.

An MCP server that records consented, attributed, paid-for receipts for open-source dependencies, settling per-call USDC payments on Algorand with on-chain attribution.

An open-source, zero-dependency Model Context Protocol (MCP) server and HTTP 402 payment gateway template built for Cloudflare Workers and Node.js. This repository provides an automated store API on Solana (USDC) alongside a native MCP Server interface. It enables AI agents (Claude Desktop, Cursor, etc.) to discover, pay for, and consume paid digital assets via standardized MCP Tools.

Open-source routing layer that splits compute jobs and inference prompts across resources using Gemini, with MongoDB-backed route books and priced allocations.

An MCP server that classifies Polymarket wallets as human or bot, scores their trading edge from 0–10, and streams current open positions.

An open-source, zero-dependency Model Context Protocol (MCP) server and HTTP 402 payment gateway built for Cloudflare Workers and Node.js. This project enables AI agents (Claude Desktop, Cursor, etc.) to natively discover, negotiate, and autonomously pay for digital resources over Solana USDC using standardized MCP tools and standard HTTP 402 Payment Required headers.

A cryptocurrency price service that provides real-time crypto pricing information through an MCP (Model Context Protocol) framework with CoinMarketCap API integration.

Enables searching and retrieving live Solana bounties from Superteam Earn, including full bounty details and currently open feeds, without requiring an API key.

Enables querying Polymarket prediction market data, including top active markets and order books, without an API key or database.

CheapestInference — unlimited flat-rate API for frontier open-source LLMs

Enables MCP hosts like Cursor and Claude to query StellarExpert's public Open API for directory entries, asset information, and ledger helper data through exposed tools.

A Python MCP server with JWT authentication and sample tools (weather + Bitcoin price), plus an AI agent that uses OpenAI to reason about and call those tools.

Provides real-time information about Ethereum addresses across multiple chains using the Model Context Protocol, featuring a Server-Sent Events endpoint for live updates.

Enables AI agents to interact with the RustChain blockchain, including checking node health, querying wallet balances, listing miners, retrieving epoch information, and browsing open bounties.

Hourly news sentiment and typed market events (hack, regulation, listing, delisting, legal) for 30 crypto pairs, with source links on every signal. Four tools cover the latest score per symbol, history, classified events and the symbol list, and a free API key works out of the box

Enables AI agents to read and bid on a paid message slot on Solana, with enforced spend limits, dry-run proposals, and an append-only audit log for every write.

Keyless MCP exchanger for AI agents — pay an exact amount to one deposit address, EMC delivered to any address. USDT(Tron) > EMC. Live at https://swap.emercoin.com/mcp

Lets an AI agent hire and pay a verified human: post real-world tasks (voice, observation, judgment) and pay in USDC via a non-custodial x402 auth-capture escrow on Base, budget frozen at deploy. Humans verify their X identity before submitting.
