  PaulieB14 (GitHub handle of the Graph Advocate author; provider.organization in the published A2A agent card)
  operates Graph Advocate, an onchain-data routing agent for The Graph Protocol at graphadvocate.com. Agents send a
  plain-English blockchain data question over A2A JSON-RPC 2.0, REST or MCP and receive the best subgraph among
  15,500+ indexed on The Graph, a ready-to-run GraphQL query and, on paid calls, the executed rows. Twenty-two paid
  endpoints add derived trader intelligence for Hyperliquid perps, Polymarket, Kalshi, Limitless and Uniswap plus
  natural-language SQL over x402 settlements on Base. There are no API keys or signups: paid calls settle in USDC on
  Base via x402 (HTTP 402 + PAYMENT-REQUIRED header), and the agent is registered as ERC-8004 agent #734 (Arbitrum)
  and #41034 (Base) under the ENS name graphadvocate.eth. The author also publishes six npx-installable MCP servers
  (Aave, Uniswap, Polymarket, lending, Limitless) that read The Graph directly.

    Routing and trader-intelligence API at graphadvocate.com. POST / speaks A2A JSON-RPC 2.0 (message/send) and is the
    free tier (3 routed queries/day per wallet-identified sender); POST /route and 22 further POST endpoints
    (/hyperliquid/*, /polymarket/*, /kalshi/*, /uniswap/*, /predmarket/spread, /narrative/divergence, /ask,
    /onchain-x402/address, /agent/score) are x402-gated at $0.01-$0.10 USDC on Base and answer 402 with x402 v2
    PaymentRequirements until an X-PAYMENT header is presented. All 23 operations in the published OpenAPI 3.1.0 are
    read-style queries; there is no API key, OAuth or signup.

  description: >-
    Hosted MCP server at https://graphadvocate.com/mcp (Streamable HTTP for one-shot JSON-RPC initialize and
    tools/list; SSE session at /mcp/sse). tools/list answers anonymously with three tools — route_data_request,
    recommend_npm_package and compare_graph_services — each carrying a real inputSchema. A stdio companion,
    graph-advocate-mcp 2.11.1 on npm, wraps the same routing surface for Claude Desktop, Cursor and other local MCP
    clients. GET /mcp/catalog lists the six protocol-specific MCP servers the router hands off to.
