  Agent Zero operates a free, anonymous remote MCP server at https://api.onchainagentintel.io/mcp
  (Streamable HTTP; a GET or a POST without Accept text/event-stream returns 406 -32600 "Client must
  accept text/event-stream"). initialize answered with protocolVersion 2025-06-18 and serverInfo
  agent-zero-intel 1.8.0; tools/list returned four read-only tools with real inputSchema, saved
  verbatim to onchainagentintel-io-mcp-tools.json; prompts/list and resources/list both return empty
  arrays. Every tool response carries an `unlock`/`upgrade` block pointing at the paid x402
  /v1/intel/* REST endpoint. The server is advertised in the agent card (x-mcp-servers), the root
  manifest (/agent.json mcpServers[]) and the OpenAPI (POST /mcp, operationId public_mcp_post).

    Agent Zero — free ERC-8004 agent-intelligence tools across Base and Ethereum. Coverage stats,
    capability leaderboards, per-agent objective signals, and a teaser of the on-chain agent-to-agent
    payment graph. Every tool is free and returns counts/coverage only; each response includes an
    `upgrade` pointer to the paid x402 endpoint that returns the full enriched data.
