passiv-mcp

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.

Works with any MCP client: Claude Desktop, Claude Code, Cursor, Windsurf, and others.

…
…"
"Scan example.com for GDPR compliance basics"
"Check the security headers on my site"
"Profile this page and tell me what meta tags are missing"

Privacy

URLs sent to a tool are fetched server-side by the mahope.tools scan proxy and not stored. HTML sent to html_to_markdown is converted and discarded immediately.

Clean Copy — browser extension, same Markdown engine
clean-copy-cli — CLI version
compliance-site-check — GitHub Action with the compliance engine

Releasing

npm run release -- patch (or minor/major) bumps the version, commits and pushes the tag. CI publishes to npm and creates the GitHub release.
