Aleo RPC API

Free public JSON-RPC 2.0 API for reading the Aleo zero-knowledge blockchain — latest blocks and heights, transactions and transitions, records, deployed programs, mapping values, public NFTs and token programs, staking balances, and chain status.

  note: 'Renamed from MCPServer 2026-09-03 (roadmap#247): the manifest self-describes as status: candidate
    — a tool list derived from the published API contracts, not an existing server. The scorer already
    read the manifest and reported mcp_server correctly; the MCPServer type was crediting the artifact-type
    surfaces with a server that does not exist.'
