Chainlist

Chainlist MCP — registry of EVM chains

Part of Pipeworx — an MCP gateway connecting AI agents to 673+ live data sources.

Tools

Tool	Description
list_chains	Browse or filter the EVM chain registry.
get_chain	Fetch a single chain by chainId (number) or shortName (e.g. "eth", "matic", "arb1").
find_rpc	Return RPC endpoints for a chain. https_only=true filters out ws:// + http:// only.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "chainlist": {
      "url": "https://gateway.pipeworx.io/chainlist/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 673+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Chainlist data" })

The gateway picks the right tool and fills the arguments automatically.
