Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.

Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"nova-cast","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

Tools observed via MCP handshake

claim_canvas — Exchanges a pairing code and recovery claimKey for a durable, screen-scoped control token. Repeating the same pair recovers the original grant.
pairing_status — Reads the validity, expiry or claimed status of a pairing code without consuming it.
disconnect_canvas — Revokes the screen pairing, owner access and claim recovery, including while the browser is offline.
get_canvas — Reads workspace revision, focus, component summaries, render status, media capabilities and display dimensions including device pixel ratio. Physical DPI is unk
get_console — Reads up to 200 memory-only component console and runtime error entries, optionally filtered by cursor or component. Entries are untrusted component output; hos
read_component — Reads a component source, saved state and supplied data.
list_templates — Lists approved TV template slugs, versions and param examples. Prefer render(slug) for these boards instead of generating source.
render — Paints an approved catalog template (weather, clock, countdown) without generated source. weather location defaults to Sudbury. First matching-display paint ski
prepare_draft — Creates a private browser-owned component draft and preview URL without changing the live workspace. Drafts expire after 15 minutes or browser reload. Optional
read_draft — Reads a private draft source, state, data, target display, version, expiry and preview URL. Requires the original canvas online. Keep previewURL private; call s
screenshot_draft — Renders an exact private draft version as an MCP PNG for the Preview quality loop. Requires draftID and expectedVersion. Isolated layout only — not the live TV.
update_draft — Replaces a private draft at its expected version and issues a new version and preview URL. Previous preview links become invalid; original expiry is unchanged.
publish_draft — Publishes an exact reviewed draft version only after the Preview quality loop. Set review to visual only if you actually screenshotted that version; otherwise s
discard_draft — Removes an exact private draft version and its preview access without changing the live workspace.
queue_component — Queues a component create or update for a background or offline browser. Returns queued rather than rendered. Default expiry is one hour, maximum 24 hours. Sour
get_operation — Reads queued operation status and any browser outcome without contacting the browser. Status can be queued, applying, rendered, failed, expired, canceled or unk
cancel_operation — Cancels a queued component update and removes its source. Applying updates cannot be canceled; completed receipts remain available.
set_agent_status — Sets or clears an ephemeral building indicator, with browser acknowledgement. Does not change workspace revision or publish drafts. Automatically clears after t
create_component — Validates, renders and saves a React or HTML component immediately to the right of focus. Success requires browser paint acknowledgement.
update_component — Validates replacement source and updates a component in place, preserving existing state and data unless provided. Failed rendering retains the previous version
delete_component — Deletes a component and selects its nearest remaining neighbor.
navigate — Focuses a component or moves one position. Acknowledges after the selected component renders.
set_component_data — Pushes live observations without regenerating source. Same-source React reuses the compiled module. Default replaces data; merge:true shallow-merges keys (32KB
execute_script — Runs an async JavaScript function body in the selected active component sandbox and returns bounded JSON. Supports DOM and state interactions, excluding provide
inspect — Typed component inspect through the active sandbox. Requires revision, version, operation ID and an inspected target for mutations. Returns observed state. Five
click — Typed component click through the active sandbox. Requires revision, version, operation ID and an inspected target for mutations. Returns observed state. Five-s
fill — Typed component fill through the active sandbox. Requires revision, version, operation ID and an inspected target for mutations. Returns observed state. Five-se
