web3ctx

Version-true web3 context for coding agents, served over MCP

An MCP server that provides web3 integration context for coding agents: human-validated integration recipes run against live chains with on-chain transaction receipts, EIP/ERC texts, ABIs, and deployment addresses. Every unit is labelled project@version and cited to a pinned commit; when evidence is missing the server abstains. Exposes five tools (web3_lookup, web3_grep, web3_search, web3_deps, web3_fetch) over a Streamable HTTP endpoint, with a CLI (npm web3ctx) and a skill package. Free authless route plus an OAuth route with higher limits via GitHub sign-in.
