Type into an input, textarea or contenteditable, and read the value back so

you can see it landed. clear (default true) replaces what is there; submit=true presses Enter afterwards.
To type a secret, pass secret={"name": ..., "key": ...} instead of text; secret://secrets lists them. The server types it and you never see it: value comes back null. A secret works only on the sites it allows, checked against the page you are on, so navigate there first.

Every call names its workspace: an X-Workspace header, or
?workspace=<name>. Sending both is refused. See Workspaces.
| Field | Type | Notes |
|---|---|---|
value |
string | The field's value read back off the element, so a caller can confirm the text landed. Null for a write whose value came from a secret โ that read is not performed at all, so the credential is never returned. |
text_from |
string | Present only when the value came from somewhere rather than being given: the kind of source it came from, never the value. |
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.
