"Create React App" matching MCP servers:

Enables ChatGPT users to create and manage Circle developer-controlled wallets on Arc Testnet, check USDC balances, estimate and send USDC using Circle App Kit, and view transaction history.

Non-custodial on-chain escrow + AI arbitration for agent-to-agent USDC payments on Base. Seven tools wrap a verified EscrowV1 contract — create, deliver, confirm, dispute, resolve — with read-only introspection if no wallet key is provided.

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

Local Ethereum wallet for AI agents — read balances and history, request payments that a human approves by password in the app popup, and fetch x402-paywalled resources with USDC on Base. Keys are encrypted on-device and never leave your Mac.

Verifies blockchain-anchored timestamp proofs entirely on the user's machine, with five tools: hash a file, verify a file against a proof, verify a known hash against inline proof data, explain what a proof asserts, and create a new proof through ProofLedger. Verification recomputes the SHA-256 and walks the Merkle path locally instead of asking the issuer; only create uses the network.

Fundraising infrastructure for AI agents on Solana: register agents, create milestone-escrowed campaigns, and donate via the x402 pay-to-call flow. Backed by Anchor programs (agent_registry, escrow, reputation) with on-chain reputation for every verified action.

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.

MCP server for defining, validating, deploying, and operating Shodai machine-readable agreements with EIP-712 permit preparation, signed participant inputs, state reads, and input history.

MCP server for Molpha oracle data, enabling AI agents to create, fetch, verify, and publish threshold-signed oracle payloads on Solana, EVM, and Starknet.

MCP server for AI agents to create and manage P2P escrow deals on Base (ETH or ERC-20).

Hashlock Markets (hashlock.markets) — sealed-bid intent-based crypto trading protocol with HTLC atomic settlement. AI agents can create, commit, and validate trading intents on Ethereum, Bitcoin, and Sui. Canonical npm package: @hashlock-tech/mcp. Not the cryptographic hashlock primitive, not Hashlock Pty Ltd (hashlock.com).

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.

MCP server for pay-per-call DeFi and crypto data via x402 micropayments on Base. 8 endpoints: token prices, TVL, funding rates, token security, gas tracker, whale monitoring, wallet profiling, and yield scanning.

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.

Non-custodial crypto swaps for AI agents: Solana (Jupiter) + 7 EVM chains (KyberSwap), 1288+ assets, cross-chain routing, priority-fee oracle, Hyperliquid perps. Returns unsigned transactions — your wallet signs, no API key, no KYC. Hosted at https://swaptitan.net/mcp

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.

MCP server for Circle's Agent Stack. Create wallets, set spend policies, send USDC, and pay x402-priced endpoints — all from a tool call.

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.

Accept crypto payments on Algorand, VOI, Hedera & Stellar. Create hosted checkout links, verify on-chain payments, and generate MPP/x402/AP2 challenges from any MCP client. Supports all 16 AlgoVoi networks (USDC + native on mainnet + testnet).

What it does: * Portfolio risk profiling (per-asset and portfolio-level) * Target allocation based on risk profile (conservative/moderate/aggressive) * Diversification scoring via HHI index * Sharpe proxy calculation * Concentration risk detection * Rule-based rebalance recommendations
