Base Onchain Tools is a Model Context Protocol (MCP) server: Base mainnet analysis: contract audits, transfer simulation, token pricing. Paid via x402. In practice that means any MCP-compatible AI assistant can call Base Onchain Tools's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://base-onchain-tools.dolerite.workers.dev/mcp and you're connected, with nothing to install locally. The current release is v1.0.0.
Base Onchain Tools is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
