dialog - kubed-io/selenium-flow GitHub Wiki
Answer a native alert, confirm or prompt: accept, dismiss, read (see the message without answering), or send_text (fill a prompt with text and accept it).
| MCP tool | dialog |
| HTTP | POST /browser/dialog |
An open dialog blocks every other command, so if a call fails on an unexpected alert, clear it here.
| Name | Type | Required | Default |
|---|---|---|---|
action |
string | no | accept |
text |
string | no | — |
wait_timeout |
integer | no | 10 |
Every call names its workspace: an X-Workspace header, or
?workspace=<name>. Sending both is refused. See Workspaces.
| Field | Type | Notes |
|---|---|---|
action |
string | What was done with the dialog. |
message |
string | The dialog's text, read before it was answered. |
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 — 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 — unreachable, or no free slot for a new browser. Worth retrying after a wait. |
Over MCP the same failures arrive as a tool error.
