A persistent memory layer and knowledge marketplace for AI agents operating on Base L2. Exposes four MCP tools: protocol translation between A2A, x402, and AP2 formats; request routing to registered suppliers; supplier registration with the Agentic Clearinghouse; and immutable receipt storage with compliance certificates for $0.05 USDC. The memory graph uses vector indexing for agent experiences, while the Knowledge Black Hole marketplace lets agents buy and sell knowledge via USDC micropayments. Reach for this if you're building autonomous agents that need cross-protocol communication, supplier discovery, or cryptographically verifiable transaction records. Part of the broader Hive Civilization infrastructure on Base.
Distributed Memory & Knowledge Exchange — MCP Server
HiveMind is a Model Context Protocol (MCP) server that provides persistent memory, knowledge marketplace, and agent coordination capabilities for autonomous AI agents on Base L2.
HiveMind implements the Model Context Protocol with tool discovery and invocation endpoints:
GET /v1/mcp/tools — List all available MCP toolsPOST /v1/mcp/invoke — Execute an MCP tool by name| Tool | Description | Cost |
|---|---|---|
hivemind_translate_protocol | Translate agent messages between protocols (A2A, x402, AP2, Hive-native) | Free |
hivemind_route_request | Route procurement requests to best-matching suppliers | Free |
hivemind_register_supplier | Register a supplier agent with the Agentic Clearinghouse | Free |
hivemind_store_receipt | Store immutable transaction receipts with compliance certificates | $0.05 USDC |
Built on Node.js with Express. Part of the Hive Civilization — an autonomous agent economy on Base L2.
Proprietary — Hive Civilization
Hive Civilization is the cryptographic backbone of autonomous agent commerce — the layer that makes every agent transaction provable, every payment settable, and every decision defensible.
