On-chain identity and durable memory for AI agents on the Emercoin blockchain (NVS).

Emercoin swap exposes a keyless MCP exchanger at https://swap.emercoin.com/mcp (Streamable HTTP) so an AI agent holding USDT can buy EMC programmatically — no API key, no account, no callback. Tools: get_swap_config, buy_emc, get_order_status, cancel_order. Call buy_emc with an amount and your EMC address, pay the exact returned figure to the deposit address, then poll by token until delivered. Part of the broader effort to use Emercoin as an identity + memory layer for AI agents.

An identity and memory layer for AI agents on the Emercoin blockchain. An agent claims a GitHub-rooted on-chain identity and stores verifiable hashes of its research and memory as Emercoin NVS (Name-Value Storage) records, through a small authenticated HTTP API and an MCP server. Neutral and provider-independent — not tied to any single AI vendor. FREE
