"Creating the Best General-Purpose Agent" matching MCP servers:

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

Enables agents to publish and search index records with custom keywords over libp2p, connecting to the Agent Index Network for decentralized peer discovery and querying.

MCP server that lets AI agents scrape web pages as clean markdown for a micro-payment in USDC, using the x402 protocol on Base network. No API keys or signup required.

An MCP server that audits ERC-8004 agent registrations, diagnosing issues and providing fix lists.

An autonomous MCP server that fetches datasets from IPFS/Filecoin, performs computation (anomaly detection, statistics, data quality scoring), and stores results via Multi-Chain Storage simulation.

An MCP server that gives autonomous coding agents deterministic, schema-validated tools for EVM smart contract development — security scanning, gas profiling, compiler diagnostics, and transaction simulation.

Enables AI agents to read and bid on a paid message slot on Solana, with enforced spend limits, dry-run proposals, and an append-only audit log for every write.

Reputation scoring for AI agent wallets on Base. 9 tools for trust scores, fraud checks, blacklist lookups, leaderboard, badge generation, and agent registration with x402 payment verification.

MCP server that checks an x402 paid endpoint before an agent pays it, and checks afterwards that the receipt opens to exactly one real on-chain settlement. Two tools, no account, no API key.

Enables AI agents to query blockchain data across EVM chains and Sui through token-efficient MCP tools, including balances, transactions, logs, NFTs, token prices, and Sui objects/events, with optional TORPC tiered ABI decoding.

Enables any MCP-capable AI agent to discover and trade onchain Solana funds — launching a fund, depositing, rebalancing, redeeming, swapping tokens, managing an app wallet, and following other traders against the live DFM API. Includes onboarding tools for headless agents and read-only versus write access controlled by an API key and a write-enabled flag.

MCP server that enables AI agents to search, describe, and fetch x402 endpoints on Base or Solana, with automatic USDC micropayments.

Read-only MCP server for discovering and ranking on-chain agents on Stellar mainnet via natural language search, reputation probes, and profile lookups.

Gives Claude a Solana wallet to send USDC, check balances, and manage blockchain transactions on Solana's devnet test network.

An Omni-Agent MCP server that provides Khmer cultural context and Web3 blockchain query tools, with security and routing built in.

An MCP server that enables AI agents to interact with the IOTA blockchain, supporting wallet management, transaction signing, and Move smart contract development. It provides tools for on-chain queries and CLI operations with a human-in-the-loop security model.

MCP Server for the IOTA blockchain that enables AI coding agents to interact with IOTA directly.

Python client and MCP server for AI agents on the PoA (minepoa.com) network: register, answer, mine, grade, vote. Register defaults to the author's referral address (disclosed; --no-referral removes it).

A stdio MCP bridge for Agent Procurement Manager (APM) that exposes apm_quote, apm_preview, and apm_categories for free supplier quotes, previews, and category discovery. It forwards requests to the hosted APM API; paid procurement runs separately through x402.

An MCP server that provides tools for interacting with EDUCHAIN, allowing Claude to query information about tokens and pools and perform swaps through SailFish DEX.

This MCP server enables aelf blockchain interactions for token creation and NFT trading, including symbol market operations and comprehensive NFT workflows.

Enables compatible AI clients to connect to a local Coinbase Agentic Wallet through stdio MCP, so they can read wallet status, public address, Base USDC balance, and saved operations without signing, transferring, trading, or making payments.

Blockchain RPC via DRPC. Exposes eth_call, eth_getBalance, gas estimation, and other JSON-RPC methods as MCP tools across 100+ blockchains

A non-custodial RWA service for AI agents on Solana that provides yield comparison, tokenized US-equity quotes, and ready-to-sign transactions.

Enables AI agents to discover, call, and pay for existing HTTP APIs over MCP with x402 paywalls, non-custodial settlement, and no code changes to the backend.

Enables AI agents to mint and manage ERC-8004 identities on Arc through free self-minting from their own wallet or paid x402 minting, including drafting registration files, confirming on-chain registration, editing owner-signed files, and checking status.

Enables AI agents to request sign-ins and payments on the Canton Network through a human's mobile wallet, where each request requires explicit human approval and hardware-backed signing.

MCP server for Taskmarket onchain task marketplace on Base L2. Enables AI agents to discover, browse, create, claim, and submit work to Taskmarket through natural language.

Exposes three read-only MCP tools for previewing Base token market data, evaluating USDC spend against SpendGuard policies before funds move, and discovering x402 payment challenges without signing or paying.

Enables local AI clients such as Claude Code and Cursor to search, analyze, and monitor prediction-market data, and, once live mode is explicitly switched on, sign and submit CLOB orders from the operator's own wallet. It runs in a safe preview mode by default, writing simulated trades to local SQLite instead of sending orders.
