Overview

AI-generated overview

A remote MCP endpoint that gives an assistant web search, scraping, Google Trends, and data lookups, billed per call in USDC on Base.

What you can do
This server exposes a hosted HTTP endpoint that an assistant can call for web search, page scraping, Google Trends data, and other data lookups. The registry description lists no individual tools, so the exact tool names and parameters are not documented here. It is a remote service rather than a local package, and the provider states that each call is paid in USDC on Base through x402.
When to use it
Consider it when an assistant needs search, scraping, or trend data and you are willing to use a third-party hosted API instead of running your own search or scraping stack. It may suit occasional lookups where per-call payment is acceptable.
Requirements
A remote MCP client that supports streamable HTTP, pointed at the provider's endpoint. No packages, environment variables, or headers are declared in the manifest, and no authentication is declared. Because calls are described as paid in USDC on Base via x402, a funded wallet or payment setup on that network is likely needed.
Before you install
The provider states that calls are paid per call in USDC on Base via x402, so using it can spend real funds; check pricing and any spending limits before connecting. The manifest declares no authentication, so consider what data your queries send to a third-party service. No tool list or README is available, so verify exactly what each call does before relying on it.

Installation

In SourceWeft

  1. Open Web Search & Data API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/xyz.kadec0%2Fweb-search-data-api/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

serp

Web search results (SERP). Keyless web search returning ranked title, URL, and snippet for a query — with locale/region targeting, freshness filters (past day, week, month, year), pagination, a news mode that adds publish date and source, and selectable backend engine (auto rotation, or pin Brave, Yahoo, or Yandex). [$0.05/call]. Params — q: search query; num_results: max results, cap 25; region: locale, e.g. us-en, uk-en, de-de; timelimit: restrict to past day/week/month/year (d|w|m|y); safesearch: string (on|moderate|off); page: result page (pagination); mode: web results or recent news (news adds date+source per item). the news index is narrow, so a long or highly specific news query that matches nothing falls through to web rather than returning empty; those items carry requestedMode=news and servedBy=web (web|news); engine: search backend: auto (recommended - rotates engines and falls back on blocks) or pin one of yahoo, yandex (web mode); news mode supports bing. when set, each result carries an 'engine' field; if the pinned engine returns nothing, auto serves instead and results also carry 'requestedEngine' Example params: {'q': 'best python web scraping library', 'num_results': 10}

Parametersparams

serp_batch

Bulk web search: up to 5 search queries in a single call, each returning ranked title, URL, and snippet, with the same locale, freshness, and news filters as the single-query web search. One paid call instead of five for research fan-out. [$0.10/call]. Params — queries: up to 5 search queries separated by '|'; num_results: max results per query, cap 25; region: locale, e.g. us-en, uk-en, de-de; timelimit: restrict to past day/week/month/year (d|w|m|y); safesearch: string (on|moderate|off); mode: string (web|news); engine: search backend: auto (recommended) or yahoo/yandex (web); bing (news) Example params: {'queries': 'python asyncio tutorial|rust tokio tutorial'}

Parametersparams

serp_multi

Multi-engine web search (metasearch). One search query fanned out across 2-3 search engines (Brave, Yahoo, Yandex) with results deduplicated by URL and merged by reciprocal-rank fusion: consensus ranking across engines instead of one engine's bias, with per-engine rank attribution on every result. [$0.05/call]. Params — q: search query; engines: comma list of 2-3 engines: yahoo, yandex (web mode). news mode has a single live engine (bing), so multi-engine is web-only; num_results: max results per engine, cap 25; region: locale, e.g. us-en, uk-en, de-de; timelimit: restrict to past day/week/month/year (d|w|m|y); safesearch: string (on|moderate|off); mode: string (web|news) Example params: {'q': 'best vector database 2026', 'engines': 'yahoo,yandex'}

Parametersparams

serp_read

Web search plus page reading in one call: answer with sources. Runs a web search, scrapes the top results, and returns the ranked search results together with each page's content as clean LLM-ready markdown, so an agent gets the SERP AND the underlying text without a second round of scrape calls. Per-page fetch errors are reported honestly per URL. [$0.08/call]. Params — q: search query; fetch_top: how many top results to fetch and extract, cap 5; maxChars: max markdown chars per fetched page; num_results: ranked results to return, cap 25; region: locale, e.g. us-en, uk-en, de-de; timelimit: restrict to past day/week/month/year (d|w|m|y); safesearch: string (on|moderate|off); mode: string (web|news); engine: search backend: auto (recommended) or yahoo/yandex (web); bing (news) Example params: {'q': 'how does x402 payment protocol work', 'fetch_top': 3}

Parametersparams

scrape

Scrape any web page to clean markdown. A keyless web scraper that converts a single URL into LLM-ready markdown plus structured metadata (title, headings, links, word count), so an agent can read a page without running a browser. A per-call alternative to Firecrawl's scrape endpoint, with no API key and no account. Single page per call, not a site crawler. [$0.03/call]. Params — url: page URL to scrape; maxChars: markdown cap Example params: {'url': 'https://example.com'}

Params — keyword: the search term; geo: ISO-3166 alpha-2 country code, e.g. US, GB, DE, JP (213 countries supported); timeframe: time window. Each response reports its own bucket size in `granularity`: past_30_days and past_90_days return a daily series, past_12_months and past_5_years weekly, windows under a day hourly (2004_present|past_12_months|past_30_days|past_4_hours|past_5_years|past_7_days|past_90_days|past_day|past_hour) Example params: {'keyword': 'bitcoin', 'geo': 'US'}
