1scan is a unified API gateway that integrates multiple etherscan-like blockchain explorer APIs and provides an MCP (Model Context Protocol) server so AI assistants (e.g., Claude in Cursor IDE) can query on-chain data. It serves developers who need a single endpoint to access balances, transactions, contracts, and more across many EVM networks.
Install via go install github.com/huahuayu/1scan@latest or build from source. Create a config.json with your API keys and rate limits per chain (e.g., for Ethereum chain ID 1). Run the API server with 1scan -config config.json and the MCP server with 1scanmcp -config config.json. In Cursor IDE, add an MCP server with the URL http://localhost:3000/mcp/sse. Customize MCP parameters (-port, -path, -transport for SSE or stdio).
1scan aggregates multiple etherscan‑compatible APIs behind a single gateway, handles load balancing across keys, and adds an MCP interface for AI assistants. You still need your own API keys from each explorer.
The server is written in Go and has no external database or runtime beyond the binary. Each user must provide API keys for the blockchains they wish to query.
1scan does not store data itself. It proxies requests to the official explorer APIs (e.g., Etherscan, BscScan) using the API keys you supply. All data originates from the respective blockchains.
The MCP server supports both SSE (Server‑Sent Events) and stdio transports. The default is SSE; you can switch with `-transport stdio`.
Authentication is done via API keys placed in the configuration file. Each chain entry maps one or more keys to a rate limit. There is no built‑in user authentication for the 1scan server itself.
SSH MCP server for AI agents: remote commands, file transfer, log search and server audits through OpenSSH.
