What it is

MCP Server

The MCP Server is a remote Model Context Protocol server that gives AI agents decoded onchain data as tools. Claude, ChatGPT, Codex and other MCP clients use it to analyze transactions, addresses, tokens and contracts, and to follow funds across bridges.

The API Reference includes the OpenAPI spec, for generating clients and agent tools.

Setup
One commandClaude Code and Codex from the terminal. ChatGPT as a connector.

Questions

What teams usually ask us

How do I add the MCP Server to Claude Code?

Run claude mcp add --transport http routescan https://mcp.routescan.io/mcp in your terminal. In Codex, run codex mcp add routescan --url https://mcp.routescan.io/mcp.

Does the MCP Server work with ChatGPT?

Yes. Add it to ChatGPT as a connector, with the server URL https://mcp.routescan.io/mcp. The docs have setup guides for Claude, ChatGPT, Codex and other MCP clients.

Is the MCP Server free?

Yes, to start. A paid API plan raises the limits.

How does the MCP Server authenticate?

With OAuth, signing in from the client, or with an API key sent as a header.
