Generates MCP servers from smart contract ABIs, enabling Claude to interact with any Ethereum contract via natural language commands.

This MCP server provides authentication via wallet sign-in (SIWE) and authorization with scoped access to read and trade portfolios, enabling secure portfolio management through natural language.

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

Search 14,000+ x402-enabled HTTP APIs by keyword. Agents pay $0.01 USDC per search via x402 micropayments on Base mainnet — no API keys or accounts required.

Enables AI agents to interact with the XMTP decentralized messaging network. Supports sending encrypted messages, managing conversations, and streaming real-time messages to any XMTP-enabled wallet address.

Provides enriched blockchain data from Codex for use with MCP-compatible clients like Claude Desktop.

Bridges AI agents with the Vibe Wallet browser extension to enable blockchain interactions such as account management, asset transfers, and smart contract calls.

MCP server for building, auditing, and querying BitBadges collections via AI. Works with Claude Desktop and other MCP clients to generate transaction JSON for BitBadges tokens and collections (deprecated, use bitbadgesjs-sdk).

Enables MCP clients to use an ERC-4337 smart account with session keys to check wallet status, send ETH or ERC-20 tokens, call allowed contracts, and manage approval requests within on-chain spending limits.

Non-custodial MCP server that routes blockchain transactions to your browser wallet (MetaMask, Rabby, etc.) for signing — private keys never leave your browser.

Free MCP server for x402toll.com, enabling AI agents to discover and use verified, pay-per-call calculators with free previews and hash verification, supporting payments via x402 protocol on Base.

Enables ChatGPT and Codex to request public keys, prepare and sign exact Nostr events, encrypt or decrypt NIP-04/NIP-44 payloads, and publish with per-relay acknowledgement, while the private key stays in the user's Alby, nos2x, or remote NIP-46 signer. Every operation is queued for local browser approval, with one-use signing intents and verification before anything is broadcast.

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.

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.
