RPC Diagnostic Agent

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.

gateway_execute_rpc

mcp.tatumio.gateway_execute_rpc({
  chain:  "ethereum-mainnet",
  method: "eth_blockNumber",
  params: []
})
// → { "result": "0x141f4ab" }   (decimal: 21099691)

Notes

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.
