"Setting up services on a Linux virtual machine" matching MCP servers:

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

On-chain delivery receipts for x402 AI-agent payments on Solana: anchors SHA-256 digests of delivered content to a PDA after settlement; buyers verify proof of delivery offline with zero trust in the seller. Live MCP endpoint + npm bridge.

Pay-per-call MCP server for on-chain blockchain data including wallet profiles, token metrics, protocol TVL, and gas prices.

Trust infrastructure for the machine economy. Gives AI agents non-custodial smart accounts (ERC-4337), x402 payments, on-chain reputation via ERC-8004 trust registry, and service discovery. 8 tools: create accounts, transfer, check balances, pay for x402 services, publish/discover services, manage payment agreements, and send encrypted messages.

An MCP server that lets an AI agent look up a RealHandles identity and cryptographically verify its signed proof.

Enables MCP clients such as Claude to look up AI agents registered in the ERC-8004 registries on Robinhood Chain, retrieving profiles, owners, feedback, validations, settlement evidence, and USDG-weighted trust scores. It is read-only and requires no wallet or API key, and can be reached either as a hosted remote endpoint or locally via npx.

An MCP server that enables AI agents to create instant public HTTPS URLs via Cloudflare Tunnels on mycrab.space. It provides tools for checking subdomain availability, setting up temporary tunnels, and managing permanent subdomains using Solana payments.

Enables AI agents to generate or import multi-chain keys, sign messages and unsigned transactions, broadcast them, and query native balances across Ambient, Solana, BSC, and Arbitrum. Private keys stay encrypted on the local machine, so agents can complete the sign-and-send half of a swap, liquidity, or bridge workflow handed over by a remote market server.

Provides comprehensive access to Ethereum Virtual Machine (EVM) JSON-RPC methods for querying blockchain data, executing smart contract calls, and interacting with any EVM-compatible network including Ethereum, Polygon, Arbitrum, and more. Enables users to check balances, analyze transactions, estimate gas, retrieve logs, and perform blockchain operations through natural language.

Installable AgentLux MCP server and embeddable toolkit for marketplace, identity, creator, services, and social flows on Base.

Enables interaction with Bitcoin's blockchain through Claude to embed and read data using OP_RETURN, create timestamps, deploy BRC-20 tokens, and store documents up to 100KB on-chain.

Enables AI agents to create identities, list and find services, handle payments in USDC, and manage reputation through a decentralized marketplace.

Enables AI agents to sign Geode blockchain transactions on the user's own machine, with keys that never leave it, by independently decoding and verifying each server-prepared transaction before approving it. Refuses anything outside allowed Geode app actions or beyond the configured per-transaction, daily, and storage-deposit GEODE limits.

A Model Context Protocol server implementation that provides endpoints for wallet-based authentication, cluster management, and name registration services.

Enables MCP-compatible agents to look up on-chain trust data for any Ethereum-compatible wallet address, returning verified, estimated and total scores plus a reputation tier. It serves this through a single self-hosted Streamable HTTP endpoint at /mcp, supporting session handling, tool discovery and tool invocation.

Enables deep, fully local cryptocurrency token research across CoinGecko, CoinMarketCap, DeFiLlama, and web sources, with structured plans, live market and DeFi data, source lookups, and saved resources. It works without an API key and keeps data on the user's machine.

Enables local, deep research on crypto tokens across CoinGecko, CoinMarketCap, DeFiLlama, and web search, with tools for live market data, exchange listings, protocol TVL, structured reports, and saved resources. It requires no API key and keeps research on your machine.

Enables AI agents to look up token risk verdicts and ERC20 facts, wallet snapshots, gas prices, transaction summaries, and Basename resolution on the Base network. Each call is paid in USDC over x402 from a dedicated wallet the user controls, with per-call price caps and a session budget.

Polymarket smart-money data for AI agents: rank traders by on-chain realised PnL and win-rate confidence interval, look up a trader's record, follow traders and pull their new fills, each once. Requires a PMWallets API key.

A bridge between AI assistants and cryptocurrency payment services that enables creating and verifying USDT transactions through the Gotas Commerce API.

Onchain agent-to-agent commerce protocol using x402 and ERC-8004. Enables AI agents to buy/sell services, manage vendor catalogs, and process payments on Base.

Enables AI agents to discover and pay for monetized services such as PDF processing and DeFi operations using USDC on the Base blockchain. It provides automatic payment processing and secure local wallet management for seamless integration with MCP-compatible clients.

Enables deep, local research on cryptocurrency tokens by aggregating CoinGecko, CoinMarketCap, DeFiLlama, and web-search data into structured reports with resource tracking. Runs without API keys, keeping queries and results on the user's machine.

Provides tools for AI assistants to query the Canton Network for data on contracts, governance, validators, and party transactions through the Lighthouse Explorer API. It enables seamless interaction with blockchain statistics, price history, and name services without requiring an API key.

Enables AI assistants to interact with the x402 payment protocol on Solana, allowing discovery and consumption of x402-enabled services, USDC payment management, and access to Solana development resources.

Enables agents to discover and execute Stellar ecosystem services and skills via a search tool and a sandboxed JavaScript execution tool, deployed on Cloudflare Workers.

Provides AI agents with 92 tools and 230+ marketplace services on Solana for prediction markets, intelligence feeds, agent identity, hiring, and more.

Enables an AI app to buy BSV with USDC on Base through a local, non-custodial cross-chain atomic swap, keeping keys on the user's machine and handling swap verification, status, withdrawal, and recovery.

Enables AI assistants to interact with LI.FI's cross-chain infrastructure, providing access to blockchain networks, token data, bridges, and transaction services through a standardized protocol.

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