outline - kubed-io/selenium-flow GitHub Wiki
Map the page: the elements worth acting on, each with a selector checked to match exactly one element, and whether it can be used now.

Use it to find selectors instead of reading HTML. When visible is false, reason says why: hidden (often a closed menu; revealed_by and open_with say what opens it), covered (blocked_by names what is on top), zero_size, offscreen or disabled.
Content is listed before navigation, header, footer and sidebars, and region names each entry's landmark. A total above count means the list was cut: scope it with selector, filter by text, or raise limit. interactive=false lists every element.
| Name | Type | Required | Default |

string | no | โ |
limit |

Every call names its workspace: an X-Workspace header, or
?workspace=<name>. Sending both is refused. See Workspaces.
| Field | Type | Notes |
|---|---|---|
count |
integer | How many elements are listed. |
total |
integer | How many matched before limit cut the list. More than count means scope it with selector, filter by text, or raise limit. |
elements |
array | What is on the page: its content first, then its navigation, banner, footer and sidebars, each in document order. |
url |
string | Current URL after the action. |
title |
string | Page title after the action. |
site_data |
object | Present only when site data was restored, skipped or forgotten in this call. |
page |
object | Present only when this browser was opened with capture=true and the page reported a failure while the call ran: what it caused, and where to read it. |
| Status | Means |
|---|---|
400 |
The request cannot succeed as sent โ a missing field, a value that was rejected, or a locator that matched nothing before the wait ran out. Do not retry it unchanged. |
401 |
Missing or wrong bearer token. |
404 |
No such browser session. It ended, the Grid reaped it, or the id was never real. Open a new one and retry. |
413 |
The body is over its cap: 1 MiB of JSON, 64 MiB of upload, 1 MiB of flow YAML. Send less; retrying it unchanged will fail again. |
500 |
Something failed that this server did not expect. |
503 |
The Grid could not serve this โ unreachable, or no free slot for a new browser. Worth retrying after a wait. |
Over MCP the same failures arrive as a tool error.
