"Notion - Productivity and Note-Taking App" 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.

Blockchain JSON-RPC on 23 EVM chains for AI agents — Ethereum, Base, Arbitrum, plus young chains like Robinhood Chain, Plasma and Ink. Free reads with no key; heavy methods (eth_getLogs, trace, debug) via a free API key or x402 USDC pay-per-call.

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 developers to build Base mini apps from start to finish with 10 specialized tools for generating manifests, starter code, deployment guides, design guidelines, and debugging assistance. Integrates official Base documentation to streamline the complete development workflow for Base ecosystem mini applications.

Tamper-evident receipts for AI agent actions. The notary layer for agent-to-agent transactions.

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

Enables interaction with blockchain chains through a note storage system that allows adding, accessing, and summarizing notes via custom URI schemes.

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.

Local Ethereum wallet for AI agents — read balances and history, request payments that a human approves by password in the app popup, and fetch x402-paywalled resources with USDC on Base. Keys are encrypted on-device and never leave your Mac.

Stamp, upgrade, and verify Bitcoin timestamps via AI agents using the OpenTimestamps protocol. No API keys required.

Connects AI agents to the Arcium encrypted computation network on Solana, offering tools for network exploration, encryption, computation management, and app templates.

Enables LLMs to interact with the YAMO Blockchain, including reading lesson memories, submitting and retrieving reasoning blocks, and anchoring provenance events.

Provides DEX price, liquidity, and volume data across multiple chains, including pair details, token pairs, search, and trending tokens.

Enables interaction with SuperScalar Bitcoin Lightning channel factories, providing protocol overviews, savings estimations, and deep dives into components like invalidation trees and MuSig2.

Enables agents to read Nockchain data through seven read-only tools, including accurate balance lookups, payment verification with confirmations, block and transaction inspection, and endpoint health monitoring. It resolves balances missed by the public address selector and avoids answering from stale nodes.

MCP server for NANO cryptocurrency operations, enabling AI agents to generate wallets, send/receive transactions, check balances, and more via JSON-RPC.

Enables fetching NFT metadata such as name, image, attributes, and collection details from a contract address and token ID on Ethereum and Base, with x402 pay-per-call micropayments.

A TypeScript library that lets you build MCP servers whose tools charge stablecoins per call and AI agents that pay for those tools automatically via the Machine Payments Protocol on Tempo.

Enables access to DePIN RF telemetry, spatial heuristics, and threat intelligence through metered MCP tools with per-record spend caps and on-chain settlement.

Low-level blockchain interface MCP server for Algorand and Voi networks, providing account/asset/app inspection, transaction search, block retrieval, TEAL compilation, and transaction simulation.
