Implementation Reference
- src/server.py:470-479 (handler)The handler function for the MCP tool 'get_first_available_block'. Decorated with @mcp.tool() for automatic registration and schema inference from signature and docstring. It creates an AsyncClient to the Solana RPC, calls get_first_available_block(), and returns a formatted string result.
@mcp.tool() async def get_first_available_block() -> str: """Returns the slot of the lowest confirmed block available. Returns: str: First available block information """ async with AsyncClient(rpc_url) as client: block = await client.get_first_available_block() return f"First available block: {block}"
