"Exploring the structure of a project" matching MCP servers:

Enables querying indexed blockchain data via subgraph GraphQL queries, part of the Pipeworx MCP gateway.

MCP server for Project CPU, a blockchain game on EVM. It lets an AI agent play on your behalf: read the world map, reveal cells, build and mine, craft, move resources, trade at marketplaces, and cash out to on-chain $CPU.

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

MCP server that prepares Proof of Invention (POI) transaction requests for submission

An MCP server that lets AI agents autonomously buy physical hats using USDC on Base — no credit card, no checkout, no human required. Browse the catalog, get a real-time shipping quote, send crypto, and we ship the hat.

Reasoning-puzzle arcade for AI agents with seven generated puzzle families, free samples, automatic answer checking, and ranked play from $0.02 USDC on Base via x402. Connect through MCP or HTTP. Browse and try samples without a wallet; run paid tools locally with an explicit spending limit.

498 MCP tools across 12 industry verticals. Marketplace, escrow, DeFi, legal, healthcare, insurance, construction, and trades. USDC payments on Base L2.

A Model Context Protocol server that enables interaction with Foundry tools through natural language, allowing users to create projects, build contracts, run tests, and manage Ethereum development environments.

Enables AI agents to play the CPU Game on EVM, including world exploration, building, crafting, and trading via natural language.

On-chain crypto indicators (EMA, RSI, VWAP, Bollinger) via Chainlink oracles.

Deterministic Risk Oracle for DeFAI Agents.

Enables AI agents to interact with Robinhood Chain via USDG payments, offering tools for balance, pricing, trading, and more.

Enables AI agents to interact with the Lido protocol for ETH staking, position management, and governance participation across Ethereum and L2 networks. It provides tools for querying balances, simulating transactions, and executing complex workflows like withdrawals and DAO voting through a safety-first interface.

An HTTP stream server for interacting with the Intuition knowledge graph, enabling users to query and manage data through tools like extracting triples, searching entities, retrieving account info, and exploring relationships.

Lets a merchant's AI agent read and act on a single non-custodial recurring payments project on Solana, by calling the project's HTTP API through tools and passing a project-bound access token. Every request is stateless, and tool output is treated as data, never as instructions.

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.

This project implements a Model Context Protocol (MCP) server that combines the power of Dune Analytics and Blockscout APIs, providing comprehensive blockchain data analysis capabilities for LLM agents and MCP clients.

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.

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.
