serpdata

serpdata is a small local bridge to the hosted HasData Google Search MCP server, which returns Google search data as JSON. Ask it a query and it brings back the full SERP — organic results, ads, knowledge graph, People Also Ask, AI Overview hooks — or the cheaper light layout; follow the tokens those responses hand back and it fetches the AI Overview block, event details, or an immersive product pop-up. News, shopping, short videos, and single-product lookups each have their own tool.

The bridge keeps no search data of its own. It serves the upstream server's tool list locally, exactly as captured from the live endpoint, and forwards each tool call upstream, returning the result untouched. The captured surface is read-only: every tool fetches public Google result pages. There is no write, purchase, checkout, messaging, or payment tool in it.

Tools

• hasdata_google_serp_serp_getSearchResults — the full Google SERP. Required: q. Optional location controls (location, uule, domain, gl, hl, lr), place/Knowledge Graph ids, tbs time and sort filters, tbm vertical, deviceType, and start/num paging.
• hasdata_google_serp_serp_light_getSearchResults — the lightweight no-JS SERP layout: faster, organic results plus AI Overview, answer box, and knowledge graph. Required: q.
• hasdata_google_serp_ai_overview_getAiOverviewResponse — the lazy-loaded AI Overview block. Required: pageToken (from a SERP response; valid 1 minute).
• hasdata_google_serp_ai_mode_getAiModeResponse — Gemini-powered AI Mode answers, with optional multi-turn continuation. Required: q.
• hasdata_google_serp_news_getGoogleNews — Google News by query or by topic/section/publication/story token. No required fields.
• hasdata_google_serp_shopping_getSearchResults — Google Shopping listings for a query. Required: q.
• hasdata_google_serp_product_getProductInformation — one product's offers, specs, or reviews from Google Shopping. Required: productId.
• hasdata_google_serp_immersive_product_getImmersive_e29f691177 — expands the Shopping immersive product pop-up (the name's suffix is upstream-generated and served verbatim). Required: pageToken.
• hasdata_google_serp_events_getEventInformation — full details for one event from a SERP events result. Required: pageToken.
• hasdata_google_serp_short_videos_getShortVideosSearchResults — the Short Videos carousel (TikTok, Shorts, Reels) for a query. Required: q.

Configuration

• HASDATA_GOOGLE_SEARCH_MCP_URL (optional) — override the upstream endpoint. Defaults to https://mcp.hasdata.com/mcp?apis=google_serp. (The override hook is this rebuild's own labelled reconstruction.)
• HASDATA_API_KEY (optional) — when set, every upstream request carries an x-api-key: <key> header, for the caller's own HasData API key. When it is not set, no key header is sent. (The header name and the env name are pinned by the original's registry record; forwarding the key from this env var is a labelled reconstruction — the original surface was captured keyless.)

Forwarding mechanics

On the first tool call the client opens a streamable HTTP session with the upstream: a JSON-RPC initialize request (protocolVersion 2025-03-26, clientInfo name serpdata), then a notifications/initialized notification, then the tools/call request carrying the caller's arguments unchanged. When the upstream answers initialize with an Mcp-Session-Id header, that value rides on every later request of the session, which is reused for the life of the process. Replies may arrive as plain JSON or as server-sent events; both are read.

Successful upstream results pass through verbatim, including any isError flag the upstream sets. Failures — a JSON-RPC error, a non-2xx status, an unreadable response, or a request that cannot be completed — come back as an isError result whose text starts with serpdata error: (this rendering is this rebuild's own labelled reconstruction).

CLI

Each tool is also a subcommand taking one JSON argument string:

npx @reneturcios/serpdata hasdata_google_serp_serp_getSearchResults '{"q":"HasData CEO","gl":"us"}'
npx @reneturcios/serpdata hasdata_google_serp_news_getGoogleNews '{"q":"open source MCP"}'
npx @reneturcios/serpdata hasdata_google_serp_product_getProductInformation '{"productId":"1234567890","searchType":"offers"}'
npx @reneturcios/serpdata --version

Exit codes: 0 on success, 1 on an isError result, 2 on a usage error.

MCP server

npx -y @reneturcios/serpdata mcp

MCP client config:

{
  "mcpServers": {
    "serpdata": {
      "command": "npx",
      "args": ["-y", "@reneturcios/serpdata", "mcp"]
    }
  }
}

Docker

docker run -i ghcr.io/cloudcorprecords/serpdata
docker run --rm ghcr.io/cloudcorprecords/serpdata --version

The container's default command is mcp, so the first form is a stdio MCP server; any other arguments reach the CLI normally.

Development

npm install
npm run build
npm test
npm run dev

The test suite runs entirely against a stubbed JSON-RPC upstream — no live network calls.
