"Node-RED" matching MCP servers:

MCP server for buying Lightning Network liquidity via Amboss Magma. Enables AI assistants to purchase inbound Lightning liquidity for a node.

Gives Claude access to Alchemy blockchain APIs by loading all API specs at startup and providing two tools: search and execute. Enables querying NFTs, token balances, transactions, and more via natural language.

Exposes an RGB Lightning Node wallet to AI agents, enabling full wallet control including balances, RGB invoices, Lightning payments, channel management, and atomic swap taker support.

Provides access to Mina blockchain data, enabling queries for events, actions, and network state information through a standardized interface.

MCP server enabling LLMs to interact with a Cardano node by wrapping cardano-cli/torsten-cli, supporting queries, transactions, staking, and governance operations.

Enables interaction with AElf blockchain nodes, allowing users to read chain status, execute contract transactions, and manage custom nodes through MCP, CLI, or SDK.

Provides AI agents direct access to the Chainstack platform, enabling blockchain node deployment, documentation search, platform status checks, and more.

Enables interaction with the Bitcoin blockchain through the Maestro API platform. Provides tools for exploring blocks, transactions, addresses, mempool monitoring, market prices, wallet operations, and node RPC calls on Bitcoin mainnet and testnet4.

A server that interfaces with the Hedera Testnet Mirror Node API, converting its OpenAPI-defined endpoints into MCP-compatible tools that can be accessed over Server-Sent Events (SSE).

Enables querying multi-chain blockchain data (stats, blocks, transactions, addresses, node info) via Blockchair's free keyless API.

Connects AI agents and developers to structured blockchain data across multiple networks through Nodit's Web3 infrastructure, enabling easy querying, analysis and interaction with blockchain ecosystems without specialized development expertise.

MCP server for Ethereum Swarm decentralized storage. Provides 12 tools for uploading and downloading data and files, managing postage stamp batches, and working with Swarm feeds — all via the Bee API. Works with the public Swarm gateway or a local Bee node.

Enables AI agents to obtain on-chain DEX aggregator quotes computed by the on-chain Quoter contract through their own RPC node, returning verified unsigned swap calldata, simulations, token info, deployment registry checks, and live staking solvency. All tools are read-only and keyless, so the agent never signs or holds a private key.

Enables AI agents to perform Bitcoin and Lightning Network payments using a non-custodial, zero-trust architecture. It provides 13 tools for wallet management, invoice creation, and payment processing while keeping node credentials local to the user's machine.

Combines Midnight Network blockchain development tools with Next.js DevTools for building decentralized applications, supporting contract development, wallet management, and Next.js diagnostics.

Comprehensive MCP server for Hedera (Hashgraph) covering 73 tools across all core services, building unsigned transactions for AI agents to propose. Never holds keys; reads via public Mirror Node.

A read-only MCP server for AI agents to access Nostr profiles, notes, search, and relay lists through user-chosen relays, without requiring an account or keys.
