"memory" matching MCP connectors:

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.

Universal pay-per-call tool API for AI agents. Web search, price feeds, hive memory, LLM routing, code sandbox. Free tier (10 calls/day, no signup). x402 payments on Base + Solana.

Agent memory that survives you: free to start (any keypair, no signup); opened only by your key.

Persistent agent memory paid per call via x402 USDC. Your wallet is your private memory namespace.
