About codex-mcp
codex-mcp is an open-source Model Context Protocol server that exposes the Codex API's enriched on-chain data — token pricing, charts, holders, and aggregated stats across 80+ networks — to any MCP-compatible AI client such as Claude Desktop or the Claude CLI. It's built for developers who want their AI assistants or CLI tools to query live blockchain data without running their own indexers, RPC nodes, or custom parsing pipelines. What sets it apart is that it bridges the same production-grade Codex data trusted by apps like TradingView and Coinbase directly into the AI/agent tooling layer via a single npx command.
