| 3 | * Media library MCP abilities. |
| 4 | * |
| 5 | * Registers Atarim/* abilities for working with media attachments — |
| 6 | * listing/searching, reading individual items with full metadata, |
| 7 | * updating attachment fields, bulk alt-text editing, safe deletion with |
| 8 | * in-use detection, uploading/replacing files, and core sub-size |
| 9 | * regeneration. |
| 10 | * |
| 11 | * Third-party image OPTIMIZER integration (ShortPixel / Smush / EWWW / |
| 12 | * Imagify, i.e. driving an installed compressor) is intentionally NOT in |
| 13 | * this cluster — that belongs in a third-party/{plugin}/ integration |
| 14 | * module. Core, plugin-free sub-size regeneration (with an optional |
| 15 | * quality re-encode of the derivatives) DOES live here, as regenerate-image. |
| 16 | * |
| 17 | * Exposed abilities: |
| 18 | * atarim/list-media Media with filters (mime, missing_alt, attached, search, date range). |
| 19 | * atarim/get-media Single attachment with dimensions, on-demand file size. |
| 20 | * atarim/update-media Update alt_text, title, caption, description. |
| 21 | * atarim/bulk-update-alt-text Array of {id, alt_text} tuples with per-id results. |
| 22 | * atarim/delete-media Single attachment delete with in-use safety guard. |
| 23 | * atarim/bulk-delete-media Bulk delete with dry_run default and confirm_in_use guard. |
| 24 | * atarim/upload-media Sideload a file into the media library. |
| 25 | * atarim/replace-media-file Replace an attachment's underlying file. |
| 26 | * atarim/replace-media-in-content Swap one attachment for another across content. |
| 27 | * atarim/regenerate-image Regenerate sub-sizes (single or batch ≤25), optional quality re-encode of derivatives; original untouched. |
| 28 | * |
| 29 | * Note: abilities are exposed automatically — class-avcf-mcp.php builds the |
| 30 | * server tool list dynamically from wp_get_abilities(), including every |
| 31 | * ability whose meta has mcp.public = true and mcp.type = 'tool'. No manual |
| 32 | * $tools entry is required. (Exposure can still be suppressed via the |
| 33 | * avcf_mcp_blocked_abilities blocklist.) |
| 34 | * |
| 35 | * @package atarim-visual-collaboration |
