Input
The tool takes a single JSON object. Every field, its type, and an example are on the generated reference at GET /mcp/tools, under this tool's name.
Calling it
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": { "name": "get_block_number", "arguments": {} }
}Put your arguments in place of the empty object. A call that fails comes back as a normal result carrying isError: true and a message naming what went wrong, not as a JSON-RPC protocol error.
The full request and response shape, and a live playground, live on the generated reference at GET /mcp/tools.
RPC
The nine read-only JSON-RPC tools: block, balance, gas, receipt, and
get_block
Read a block by tag (a hex block number or `latest`/`earliest`/`pending`/`safe`/`finalized`) from the configured chain. Returns the block header and its transactions; pass `fullTransactions: true` to receive full transaction objects instead of hashes. The default tag is `latest`.
