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\nFiles stay in this browser. Use still PNG, JPEG or WebP images, up to 20 MiB per file, 40 MiB combined and 16 million decoded pixels combined. Outputs total at most 100 MiB. Processing stops after 30 seconds. Source metadata and color profiles are not copied.\n\n### Inputs and settings\n\nNo free-text input is required. Use the file inputs and/or settings below.\n\nAccepted browser files: `.png,.jpg,.jpeg,.webp`. Multiple files are supported.\n\nBrowser file-input limit: 41943040 bytes in total. HTTP limits can differ.\n\n| Setting | Meaning | Control type | Default | Constraints |\n| --- | --- | --- | --- | --- |\n| `mode` | Channel operation | select | \"split\" | Allowed: split, combine |\n| `redIndex` | Red plane position | select | \"0\" | Allowed: 0, 1, 2, 3 |\n| `greenIndex` | Green plane position | select | \"1\" | Allowed: 0, 1, 2, 3 |\n| `blueIndex` | Blue plane position | select | \"2\" | Allowed: 0, 1, 2, 3 |\n| `alphaIndex` | Alpha plane position | select | \"3\" | Allowed: -1, 0, 1, 2, 3 |\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\nFiles stay in this browser. Use still PNG, JPEG or WebP images, up to 20 MiB per file, 40 MiB combined and 16 million decoded pixels combined. Outputs total at most 100 MiB. Processing stops after 30 seconds.

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\": \"image-channel-splitter\",\n \"category\": \"image-tools\",\n \"built\": true,\n \"requirements\": \"Files stay in this browser.
