No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.

MCP server that gives AI agents free web tools — zero auth, zero dependencies.

Four tools, backed by the free APIs at mahope.tools:

Tool What it does
html_to_markdown Convert HTML to clean Markdown or plain text (max 50 KB/call)
compliance_scan 9-point EU compliance scan: privacy policy, terms, cookie consent, imprint, accessibility statement, DPA, security headers, meta tags, hreflang
profile_page Page profile: meta/OG tags, JSON-LD, heading structure, alt-text coverage, security headers, score + grade
check_security_headers CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy

Listed in the official MCP Registry as io.github.mahope/passiv-mcp.
