Tools
| Tool | Description | Behaviour |
|---|---|---|
| dp_check_domain_breaches | Check whether a domain appears in known public data breaches (via the Have I Been Pwned breach catalog). Returns matching breaches with dates, exposed data classes, and account counts. Domain-level only — no personal email is queried. | Read-only |
| dp_check_email_security | Check a domain's email authentication posture — SPF, DKIM, and DMARC DNS records — and return an A–F grade with explanations. Read-only DNS lookups; no email is sent or stored. | Read-only |
| dp_check_password_pwned | Check whether a password has appeared in known breaches using HIBP k-anonymity. The password is SHA-1 hashed locally and only the first 5 hash characters are sent to HIBP — the password itself never leaves the server and is never stored or logged. Returns whether it was found and how many times. | Read-only |
| dp_check_whois_privacy | Look up a domain's public WHOIS/RDAP registration record and flag exposed personal identity fields (registrant name, email, phone, address). Read-only RDAP lookup. | Read-only |
| dp_compare_tools | Fetch the full Privacy Protocol records for 2–5 tools by slug for side-by-side comparison (ADO score, jurisdiction, encryption, PII requirements, audit status). Use to help a user choose between shortlisted tools. | Read-only |
| dp_find_alternatives | Given a mainstream or privacy-hostile product/service (e.g. 'Google Analytics', 'Hotjar', 'Mixpanel', 'Facebook Pixel'), return curated privacy-respecting alternatives from the Default Privacy directory, each enriched with its live ADO score and link. Use when a user wants to replace a tracking or privacy-hostile tool. | Read-only |
| dp_get_glossary_term | Fetch a single glossary term's full definition and content by slug. | Read-only |
| dp_get_guide | Fetch a single guide's full markdown content and metadata by slug. | Read-only |
| dp_get_related_tools | Given a directory tool slug, return other tools in the SAME category ranked by ADO score — a shortlist of peers/alternatives within the directory. Excludes the input tool. | Read-only |
| dp_get_tool | Fetch a single privacy tool's full Privacy Protocol record by slug — description, ADO score, jurisdiction, encryption, PII requirements, platforms, and audit status. | Read-only |
| dp_list_categories | List the privacy tool directory's category groups and subcategories with tool counts. Use the returned slugs to filter dp_search_tools. | Read-only |
| dp_search_glossary | Search the privacy & security glossary for defined terms. Returns term, definition, and link; use dp_get_glossary_term for the full entry. | Read-only |
| dp_search_guides | Search Default Privacy's long-form privacy how-tos (data-broker removal, keeping a home address off people-search sites, running your own VPN, and banking privacy). Filter by category. Returns metadata and links; use dp_get_guide for full content. | Read-only |
| dp_search_tools | Search the Default Privacy directory of vetted privacy tools (VPNs, email, browsers, messengers, password managers, etc.). Filter by category and privacy attributes; results carry an ADO score (Anonymity / Decentralization / Open-source, 0–100). Prefer higher ADO when recommending. | Read-only |
