"Understanding and Using JSON" matching MCP servers:

Connects to Lightning Network nodes and enables natural language queries for channel information, providing both human-readable responses and structured JSON data through the Model Context Protocol.

MCP server that lets AI agents discover and pay for .agent services using USDC over x402, with daily budget controls and payment link creation.

Decodes raw EVM bytes into human-readable JSON via tools for logs, calldata, selectors, and ABIs across multiple chains. Read-only, keyless, and stateless, with optional x402 payment settlement.

Enables AI agents to create and post signal coins on the Base blockchain through tools for media uploads, transaction generation, and on-chain submission. It supports both fully headless automated execution and manual signing modes using the x402 payment protocol.

Provides cross-chain bridge and swap tools for AI agents using the Relay Protocol to interact with multiple blockchain networks. It enables agents to query supported chains, obtain transaction quotes, and generate unsigned transaction data for token transfers and swaps.

An MCP server that enables AI agents to query the Canton Network for balances, rewards, classified transactions, CC prices, and directory information using natural language.

MCP server enabling AI agents to perform cross-chain token swaps through NEAR's intent-based architecture using the Defuse Protocol, with token discovery, quote retrieval, swap execution, and status tracking.

Enables AI assistants to query blockchain data across 30+ networks via Infura, using natural language for blocks, transactions, contracts, and more.

Read-only access to the live NOVAI blockchain (an AI-native L1) over public JSON-RPC. Query blocks, transactions, AI entities, on-chain signals, oracle anchors, and memory objects. No keys, no write paths.

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.

MCP server that lets AI agents browse, create, and submit tasks on Taskmarket, and check wallet balances, using the official CLI for secure key handling.

An MCP wallet server that lets an AI agent hold, send, and spend USDC on Hedera, using the x402 standard for HTTP payments.

Enables AI agents to create and manage MPC wallets across EVM, Solana, and Cosmos blockchains through the Para REST API. It provides tools for wallet creation, status tracking, and secure data signing using Multi-Party Computation.

Provides a unified MCP interface over Uniswap V2, V3, and V4 across multiple chains via The Graph, enabling agents to query token prices, top pools, pairs, and recent swaps with clean JSON output.

Enables cross-chain bridging, multi-chain token swaps, and real-time pricing across over 50 blockchain networks using the Relay Protocol REST API. It allows users to browse thousands of tokens, generate quotes, and monitor transaction status directly through natural language.

A local-first MCP server that enables AI agents to query the Sui blockchain using gRPC, GraphQL, and Archival Service, with auto-routing and LLM-friendly responses.

Enables AI agents to fetch and independently verify on-chain data such as account balances and contract code hashes using Merkle proofs and ECDSA signatures, with x402 payment integration.

Discovers related blockchain addresses and domain names for web3 identities across different platforms including Ethereum, Farcaster, Lens, and ENS using next.id's relation server data.

Enables AI agents to fundraise for projects on the Base chain using milestone-based escrow management. It allows agents to create proposals, track funding progress, and generate payment release requests upon completing work.

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.
