"Understanding File System Operations: Read, Write, and Edit Directories" matching MCP servers:

A read-only MCP server for Hyperliquid that provides public market data (prices, order books, funding) and any wallet's positions, orders, and fills via MCP tools, without requiring a private key.

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

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

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 querying Base Network blockchain data including blocks, transactions, balances, and smart contracts on mainnet and testnet.

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

Provides on-chain trust verification for AI agents through the Vaultfire Protocol, enabling read-only trust checks and write operations like agent registration and partnership bonds across multiple blockchains.

Enables MCP clients to inspect and transact with a token launchpad on Robinhood Chain, offering read tools, resources, prompts, and dry-run-first write tools. Supports launches, curve and V4 swaps, graduations, fee claims, buybacks, and factory admin operations

Enables read and write interactions with 60+ blockchain networks through Claude Desktop, providing a standardized multi-chain API for transaction management, account insights, staking, and token interactions.

Enables AI agents to read chain data, execute transactions, swap tokens, and manage wallets on Solana through 38 tools across 7 modules. Supports write operations with a private key and includes built-in prompts for common workflows.

Enables Claude to interact with the Ethereum Name Service (ENS) system to resolve names, check availability, retrieve records, and perform other ENS-related operations through natural language.

Exposes TradeTrust document/eBL operations on the Zetrix L2 as MCP tools, enabling verification, status checks, and finality lookups, with optional write capabilities for issuing, minting, transferring, and signing documents.

Identity + memory layer for AI agents on the Emercoin blockchain — read open, write via GitHub OAuth

Enables interaction with Ethereum-compatible smart contracts through their ABI, allowing both read operations (querying state) and write operations (executing transactions) dynamically based on the contract's interface.

Provides complete HTTP/JSON access to all 100+ Emercoin RPC endpoints with integrated formatting utilities. Enables blockchain operations, name system management, wallet functions, and mining operations through a comprehensive REST API interface.

Enables read and write access to the Celo blockchain including balance checks, token transfers, swaps, agent identity (ERC-8004), and x402 micropayments, returning unsigned transactions for user signing.

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.

Read-only on-chain query surface for the AgentCivics civil registry on Sui — soulbound AI-agent identities, on-chain memories, reputation, refusal records. Hosted, no install, no keypair. For write tools (register, write_memory, record_refusal), install the npm package @agentcivics/mcp-server locally and supply your own keypair.
