Connect Codex to Beaconchain MCP. Check if your ethereum node is syncing, get health status of the beacon chain node, and more using natural language, with authentication handled for you.
Beaconchain is a real-time analytics platform for Ethereum 2.0's Beacon Chain. It provides detailed insights into validators, blocks, and overall network performance.
Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With the Beaconchain MCP integration, Codex can look up validators and rewards, track validator income, inspect slots and epochs, check network performance, and resolve ENS names, all without leaving the terminal or the app, whichever you prefer.
For exact tool slugs and parameter tables, see the tool catalog in the Composio docs.
Apart from a managed and hosted MCP server, you will get:
Run this command in your terminal to add the Composio MCP server to Codex.
It will initiate the authentication in a browser window, authorize Codex to access your Composio account.
To authenticate manually, run the login command to open a browser window and authorize Codex to access your Composio account.
codex mcp login composioRun codex mcp list to confirm Composio appears as a registered MCP server.
codex mcp listCodex App follows the same approach as VS Code.

.codex/config.toml[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }Ask Codex for a Beaconchain task. The first time, Composio asks you to connect your Beaconchain account.
For example, ask it to:
The beaconcha.in MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your beaconcha.in account. It provides structured and secure access to Ethereum Beacon Chain data and analytics, so your agent can monitor network performance, inspect blocks and slots, analyze validator activity, track rewards and balances, and resolve ENS names on your behalf.
You've successfully integrated Beaconchain with Codex using Composio's MCP server. Now you can interact with Beaconchain directly from your terminal, VS Code, or the Codex App using natural language commands.
