Web Research Agent MCP Server

web-research-agent-mcp

MCP server that gives Claude, Cursor or any MCP client six research tools: company_profile, site_audit, page_to_json, email_check, sitemap_urls and page_diff. It is backed by the Web Research Agent API on RapidAPI. You need your own RapidAPI key. The free plan gives you 50 calls/month.

Setup

1. Subscribe on RapidAPI (Free plan) and copy your X-RapidAPI-Key.
2. Add the server to your MCP config:

{ "mcpServers": { "web-research-agent": { "command": "npx", "args": ["-y", "github:elaysuu/web-research-agent-mcp"], "env": { "RAPIDAPI_KEY": "YOUR_KEY" } } } }

Tools

• company_profile(url): name, description, logo, socials, emails, key pages, price mentions, tech stack.
• site_audit(url, max_links?): 0–100 score, SEO, performance, security-header and broken-link issues.
• page_to_json(url, max_text?): meta, OG, JSON-LD, headings, links, images, clean text.
• email_check(email? | domain?): syntax, MX/null-MX, SPF, DMARC policy, disposable/free/role flags, verdict and 0–100 score (live DNS, no SMTP probe).
• sitemap_urls(url, limit?, max_sitemaps?, since?): every URL a site publishes in its sitemaps, with lastmod; since returns only changed pages.
• page_diff(url, previous_text? | previous_hash?, selector?): content hash plus added/removed lines since your last check — a stateless change monitor.

The crawler respects robots.txt and refuses private and internal addresses. MIT license.

Hosted / pay-per-call

Also available hosted on MCPize with pay-per-call pricing (no RapidAPI key needed). Self-hosters of the backend can use direct mode with env WRA_DIRECT_URL and WRA_DIRECT_TOKEN.
