It provides tools for querying balances, simulating transactions, and executing complex workflows like withdrawals and DAO voting through a safety-first interface.

Teaches AI coding agents how to reason correctly about MetaMask Embedded Wallets / Web3Auth architecture, SDK choice, key derivation, auth flows, and common integration pitfalls.

Connects AI agents to the Arcium encrypted computation network on Solana, offering tools for network exploration, encryption, computation management, and app templates.

A Model Context Protocol server that enables LLMs like Claude to interact with the Nostr social network, allowing for fetching user profiles, text notes, and zap payment information.

Enables agents to access fixed-cost loan tools over MCP and operate a wallet that signs transactions under spend limits.

Enables AI clients to query and operate EVM-compatible networks, including Bitgold mainnet/testnet, through tools for blocks, transactions, wallets, tokens, NFTs, contracts, and gas estimation, with preview-and-confirm safeguards for fund-moving actions.

Enables agents to burn ZC to publish messages or knock at ENS doors, privately zip and unzip assets into Ethereum Privacy Pools, pay zk.money tags in private DAI, and inspect notes, door pages, daily activity, and prices via MCP tools.

A minimal demo of the x402 payment protocol protecting an MCP tool endpoint, showing how to charge for MCP tools using real 402 rejections and testnet payments.

MCP server that lets any AI agent operate a wallet directly on-chain: create wallets, send, swap, bridge, and deploy contracts across EVM and Bitcoin networks.

mcp server that allows to do actual actions related to solana first version adds knowledge about RPC methods and how to call them

Turns Base44's AI builder into a Monad web3 app builder, enabling anyone to vibecode consumer crypto apps (invisible wallets, gasless USDC payments) by describing them in English.

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.

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.

MCP Server for the Luno Cryptocurrency API

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.

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.

Enables LLMs to interact with the AT Protocol ecosystem, including Bluesky, through natural language. Supports public data access without authentication and full write operations with authentication.

An MCP server that enables cross-chain token transfers via the Stargate protocol.

Trust infrastructure for AI agents on Base. DEX Spread Oracle (live Uniswap V3 prices), on-chain escrow, insurance pool, and collective knowledge base. 7 smart contracts. Pay-per-query via x402 micropayments in USDC.

Gasless USDC, USDT and USDG transfers and swaps for wallets with no ETH, SOL or TRX. Agents check a wallet for stuck or frozen stablecoins, quote a send or a swap into the gas coin, collect the wallet signature and track the transfer. Base, Arbitrum, Ethereum, HyperEVM, Robinhood Chain, Solana and Tron.

MCP server that enables AI signing agents to pre-flight transactions by checking ERC-7730 descriptor safety, explaining function semantics, and scanning contracts for danger primitives.

MCP server that builds unsigned Paraswap token swap transactions for self-custody wallets, holding no keys and signing nothing. It returns raw transaction data for a human to review and approve before execution.

Lets AI agents check whether an EVM wallet address carries an EIP-7702 delegation across eight chains (Ethereum, Base, BNB Chain, Arbitrum, OP, Polygon, Gnosis, Unichain) and learn how to obtain a deeper paid report with delegate bytecode heuristics and risk levels. Read-only, never touching private keys or seed phrases.

MCP server for OrcaTrace, a pay-per-call Polymarket intelligence feed for AI agents. It provides tools to track smart money, whale entries with calibration, market repricings, and digests across 42K prediction markets, with payments settled via x402 on Base.

Provides live cross-DEX market data on six EVM chains, including per-venue prices, liquidity, and gross spreads with optimal trade sizes. Enables AI agents to query real on-chain data for BSC, Polygon, Arbitrum, Base, Avalanche, and Optimism via MCP tools.

Provides AI agents with direct access to the Ray Group DeFi UX rubric, named patterns, and cognitive-bias glossary for grounded UX assessments of DeFi protocols.
