    REMOTE: POST https://graphadvocate.com/mcp with Accept: application/json, text/event-stream answered
    `initialize` (protocolVersion 2024-11-05, serverInfo graph-advocate-mcp 1.0.0, capabilities tools/prompts/
    resources with listChanged false) and `tools/list` (3 tools with inputSchema) with no credentials — the live
    schema is NOT gated. The GET descriptor advertises "connect via SSE at /mcp/sse for full session", but
    GET /mcp/sse returned 404 on 2026-09-19 both with and without Accept: text/event-stream; the one-shot
    Streamable-HTTP-style POST is the surface that works today. Claude Desktop config published in the quickstart
    uses {"url": "https://graphadvocate.com/mcp"}.
    LOCAL: graph-advocate-mcp 2.11.1 on npm (maintainer paulieb, MIT, bin graph-advocate-mcp -> dist/index.js,
    deps @modelcontextprotocol/sdk + zod, published 2026-08-13, repository github.com/PaulieB14/graph-advocate,
    source dir mcp/ in that repo). Install string is the npm bin name; the provider's docs show `npx` for its
    sibling packages and the package declares a bin, so `npx -y graph-advocate-mcp` is the standard invocation.
    Paid calls made through either surface settle by x402 (USDC on Base) — payment, not authentication.

    The router hands off to six protocol-specific stdio MCP servers by the same author (GET /mcp/catalog, saved
    verbatim). They read The Graph directly with the caller's own GRAPH_API_KEY and are catalogued in
    packages/graphadvocate-com-packages.yml; they are not this hosted server.
