Chainlist MCP — registry of EVM chains
Part of Pipeworx — an MCP gateway connecting AI agents to 673+ live data sources.
| 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. |
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"
}
}
}
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.
