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\nPaste standard padded Base64 or a data:application/pdf;base64 URL. Spaces and line breaks are ignored. Up to 1,000,000 input characters. The decoded bytes must be an unencrypted, readable PDF.\n\n### Inputs and settings\n\nText input: Base64-encoded PDF.\n\nExample or placeholder shown in the interface (not a validated fixture):\n\n```text\nJVBERi0xLjcK…\n```\n\nPaste the complete Base64 content. This example is only the start of a PDF encoding. Up to 1,000,000 characters. Review the settings before running.\n\nNo additional settings are declared for this tool.\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\nInput is limited to 1,000,000 characters and must decode to a readable, unencrypted PDF. Base64 is encoding, not encryption. Your pasted content is processed in the browser.\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\": \"base64-to-pdf\",\n  \"category\": \"pdf-tools\",\n  \"built\": true,\n  \"requirements\": \"Input is limited to 1,000,000 characters and must decode to a readable, unencrypted PDF.
