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

Unifies 11 protocol specification repositories (EIPs, BIPs, CIPs, etc.) and canonical contract addresses across 10 chains into a local FTS5 index, enabling coding agents to retrieve exact spec text and contract addresses via natural language queries.

A curriculum that teaches AI agents how to spend their own money. Sixteen lessons from "what is a wallet" to your first x402 purchase. Teacher, not butler — never signs, pays, or holds keys.

A backend service that enables interaction with the Binance exchange API, allowing users to view their portfolio, convert tokens, and execute trades with minimal market impact.

Enables AI applications to interact with the Bitcoin Network, manage wallets, check balances, convert prices, and send transactions.

An MCP server that connects ZetaChain CLI into your editor. Query balances, send cross-chain transactions, and manage universal contracts directly through MCP.

A production-ready MCP server that wraps the Kxcoscan blockchain explorer API into structured endpoints for AI agents. It enables users to query wallet balances, transaction histories, token transfers, and contract details via natural language.

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.

Enables AI agents to make pay-as-you-go AI inference requests through x402 with automatic Solana USDC payments, no API keys or registration, while enforcing configurable spending limits.

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.

Enables agents to search and inspect live service offerings, generate x402 payment snippets, and understand blockchain-only balance policies.
