The Suite

Five tools, each with a distinct purpose, working in concert.

Seer

Domain Diagnostics

Multi-interface domain intelligence toolkit providing WHOIS and RDAP lookups, DNS resolution and propagation monitoring, SSL and DNSSEC analysis, availability checking, subdomain enumeration, and high-concurrency bulk operations.

20 Python functionsAvailability checkingDNSSEC validationSSL chain analysisCT log enumerationBulk ops (50 concurrent)

Tome

Domain Knowledge Base

Reference database for internet TLDs, DNS record types with RFC references and examples, and a glossary of domain industry terminology. Data models complete, datasets being populated.

Uses / Bundles
1

Seer and Tome form the foundation — Rust performance cores with Python bindings providing raw domain diagnostics and reference data.

2

Tower consolidates both into a single MCP server, while Scrolls provides the contextual knowledge that AI agents need to use them effectively.

3

Familiar sits at the top — a conversational agent with 50 tools that leverages Seer, Tome, and Scrolls' knowledge to answer questions in natural language.
