MCP servers

chainlist-mcp

The network module. It gives the agent live chain data from Chainlist, so no chain ID or RPC endpoint needs to be hardcoded.

From source

bash

git clone https://github.com/ROXI-OS-SI/chainlist-mcp.git

No parameters.

Example#

prompt

Which RPC endpoints for Arbitrum One don't track users?

The agent calls get-chain-list, finds Arbitrum One, and filters its RPC list to endpoints whose tracking is none. Part of an entry looks like:

get-chain-list (excerpt)

{
  "name": "Ethereum Mainnet",
  "chain": "ETH",
  "rpc": [
    { "url": "https://xrpc.cl/eth", "tracking": "none" },
    { "url": "https://rpc.hostdefi.com/api/rpc/ethereum", "tracking": "limited" }
  ]
}

chainlist-mcp has no wallet access and needs no configuration, so it's safe to enable for any agent.
