# WellknownBot

> Self-described in its user-agent as "WellknownBot/0.1" with listing and claim URLs, i.e. a directory crawler that creates a listing for the site and offers a claim link. No operator page or public documentation could be found as of 2026-10-23.

## Dossier

- Kind: Agentic web & MCP registries
- Operator: unknown
- Documentation: none found
- robots.txt tokens: none documented
- Feeds: registry / directory
- Respects robots.txt: Not documented. Name collides with well-known.dev's WellKnownBot (UA 'Mozilla/5.0 (compatible; WellKnownBot/0.1; +https://well-known.dev/about/#bot)', obeys only robots groups naming it), but the observed UA format (different casing, listing/claim fields) does not match, so it is not attributed.
- Verification: Unknown
- Labels matched in our logs: wellknownbot

## Why it matters to New Runtime (our interpretation)

Points to a directory that auto-lists sites with .well-known agent resources and invites the owner to claim the listing.

## Observed behaviour

- Baseline 2026-10-23 (93-day window): 104 requests on 20 days; first seen 2026-09-25, last seen 2026-10-23; Regular.

Identity: A family name is what a client claims in its user agent. It is verified only when its request came from the operator's published IP ranges or passed forward-confirmed reverse DNS, as reported per family in /crawler-journeys.json. Anyone can claim any name.
