Canonical recipe
End-to-end procedure: RPC Diagnostic Agent. Discover chains, list methods, execute a diagnostic RPC call.
Risk
Read-only by default. Write methods exist on most chains but must be gated by human approval in agentic flows.
RPC Gateway
Direct JSON-RPC and chain-native protocol access to 130+ networks through a single managed gateway.
rpc , 3 MCP tools
Why agents use it
Lets agents query chain state, simulate transactions, and call contracts without operating their own nodes.
MCP tools
- gateway_get_supported_chains
- gateway_get_supported_methods
- gateway_execute_rpc
Example: gateway_execute_rpc
A representative invocation. Drop this into an MCP-capable agent (Claude Desktop, Claude Code, Cursor, Windsurf) after the Tatum MCP server is configured.
mcp.tatumio.gateway_execute_rpc({
chain: "ethereum-mainnet",
method: "eth_blockNumber",
params: []
})
// → { "result": "0x141f4ab" } (decimal: 21099691)
