Overview

AI-generated overview

Remote SEO and keyword data API giving an assistant 44 tools for search volume, Google Trends, backlinks, domains, SERPs, Maps and audits, paid per call.

What you can do
  • Research keywords: search volume, CPC, competition, difficulty, intent, ideas, variations, history and clickstream volume
  • Track demand with Google Trends: interest over time, related queries, regions and comparisons
  • Analyse domains: overview, traffic estimates, ranked keywords, competitors, keyword gaps, top pages and historical visibility
  • Audit backlinks: profile summary, link lists, referring domains, anchors and monthly history
  • Check search results: Google, Bing and YouTube SERPs, autocomplete, historical SERPs, Maps places and business listings
  • Audit pages and marketplaces: on-page SEO checks, Lighthouse page speed, Amazon keywords and Amazon search results
When to use it
Useful when an assistant needs SEO or market research data on demand: keyword lists and prioritisation, competitor and traffic comparisons, link audits, local lead lists, or checking who ranks for a query without building your own scrapers.
Requirements
A remote streamable HTTP endpoint; no local install, account or API key is declared. Each tool call is paid in USDC on Base through x402 v2, so a funded wallet and an x402-capable MCP client are needed; listing tools is free.
Before you install
Every tool call spends money, from about $0.012 to $0.25 per call, so loops or large batches can add up quickly. Payment is signed and sent in the request metadata, which means a wallet key is involved. Results are third-party estimates, and titles, snippets and other third-party text in them should be treated as untrusted input.

Installation

In SourceWeft

  1. Open SEO and Keyword 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/com.duoleads.keywords%2Fkeyword-search-volume-google-trends/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.
