Registration alone is not a production-quality guarantee. |\n| Browser execution | Use the visible action or interactive controls. |\n| Browser processing | Browser; see tool notes for network behavior. |\n| HTTP API | Not callable through HTTP. |\n| Browser-agent interface | run_current_tool |\n\n### Implementation notes\n\nEdits standard PDF document-information fields. Blank fields keep their current values unless you enable clearing. Existing XMP metadata and hidden data are not removed. This is not a redaction or anonymization tool.\n\n### Inputs and settings\n\nNo free-text input is required. Use the file inputs and/or settings below.\n\nAccepted browser files: `.pdf`. Choose one file.\n\n| Setting | Meaning | Control type | Default | Constraints |\n| --- | --- | --- | --- | --- |\n| `title` | Title (blank keeps current) | text | \"\" |  |\n| `author` | Author (blank keeps current) | text | \"\" |  |\n| `subject` | Subject (blank keeps current) | text | \"\" |  |\n| `keywords` | Keywords, separated by commas | text | \"\" |  |\n| `clear` | Clear a field when its input is blank | checkbox | false |  |\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nThis edits standard PDF document-information fields only. It does not remove XMP metadata, annotations, hidden content or personal data elsewhere in the file. It is not redaction or anonymization, and saving creates a new copy.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n  \"id\": \"pdf-metadata-editor\",\n  \"category\": \"pdf-tools\",\n  \"built\": true,\n  \"requirements\": \"This edits standard PDF document-information fields only.
