"Implementing CRUD Operations and OAuth in Supabase with PostgreSQL and Expo" matching MCP servers:

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

Production-grade Model Context Protocol (MCP) server delivering paywalled Web3 micro-services powered by autonomous x402 payment challenges on Base Mainnet.

Wallet-funded MCP client for six paid Utilia tools: Solana priority fees, transaction diagnosis and simulation, token-risk checks, PDF-to-Markdown, and audio normalization over x402. MIT-licensed and installable from npm.

Enables interaction with Binance Smart Chain, including wallet management, token transfers, contract execution, PancakeSwap swaps, and four.meme token creation.

MCP server for Chainlink Runtime Environment, enabling build, simulate, deploy, and manage CRE workflows from any MCP client.

Enables AI-powered cryptocurrency trading and analytics across multiple exchanges and blockchains, with integrated Telegram bot and live trading capabilities.

Integrates Base44 data management, Theta GPU compute and blockchain, and Wave OS intelligence into a single MCP server, enabling AI assistants to perform CRUD, AI inference, smart contract operations, and agent orchestration.

Enables interaction with Recall services for blockchain storage operations, including account management, bucket creation, and object CRUD.

Evaluator-as-a-service for autonomous AI agents implementing ERC-8183/Virtuals ACP v2.0. Agents submit jobs for scoring across three tiers, settle fees in USDC on multiple chains, and receive attestations.

Enables interaction with Phala Network's confidential computing infrastructure, including TEE worker management, AI agent deployment in secure enclaves, and blockchain operations.

Enables blockchain payment operations across multiple networks including Base, Ethereum, BSC, Polygon, and Avalanche. Supports balance queries, token transfers, transaction tracking, wallet management, and gas fee estimation with built-in security limits.

Enables agents to interact with the Pons launchpad on Robinhood Chain, providing live protocol data, token launch, trading, and wallet operations through a read-only default with explicit signing opt-in.

A production-grade MCP server for Web3, enabling real-time multi-chain wallet execution, smart contract auto-compilation and deployment, token swaps, and asset hosting via Supabase.

An account-scoped MCP connection hub for Claude, OpenAI and Grok, enabling private MCP endpoints, OAuth sign-in, Solana wallet binding, and content publishing via MCP tools.

Enables interaction with ResilientDB blockchain through smart contract operations, GraphQL queries, and key-value storage operations.

Provides access to cryptocurrency exchange APIs through CCXT, enabling market data retrieval, account balance checks, and trading operations across multiple exchanges like Binance, Coinbase, and Kraken with built-in security features.

Checks live x402 routes across Base, Solana, and Algorand before agents spend. $0.003 USDC settles only for a valid live eligible route; normal typed misses are not settled. Free preview and validate tools. Seller payment is separate; the agent keeps its wallet. Optional signed route-binding receipts support buyer-side checks.

Provides read-only tools to query live Polymarket prediction-market data via the public Gamma API, enabling search, browsing, and detailed market and event information.

Rug pull risk scores and on-chain forensics for memecoins on Solana, Ethereum, Base and Robinhood Chain - launch-bundle detection, funding-origin tracing, deployer history, insider networks and whale flow. 15 read-only tools.

Enables AI agents to make pay-as-you-go AI inference requests through x402 with automatic Solana USDC payments, no API keys or registration, while enforcing configurable spending limits.
