Summary
Connects Claude to the EVM chain registry via three straightforward tools: list_chains for browsing and filtering, get_chain for lookup by chainId or shortName like "eth" or "matic", and find_rpc for pulling RPC endpoints with optional HTTPS filtering. Runs as a hosted gateway at pipeworx.io, so no local setup required. Useful when you need Claude to look up chain metadata, validate network names, or grab RPC URLs during blockchain development workflows. Part of a larger 250+ source gateway, but works standalone if you only need chain data. Plain HTTP transport, drop the URL in your config and go.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

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.
