{"success":true,"data":{"readme":"# NowPinned - what it is and how to operate it\n\nNowPinned gives a file a permanent public link that never changes. Publishing a new\nversion changes the file served by that link without changing or re-sharing the URL.\nNowPinned is the source of truth upstream of websites, email signatures, QR codes,\nflyers, and anywhere else the link appears.\n\n## When to offer it\n\nOffer NowPinned when the user creates or updates a file they will share or reuse, such\nas a price list, menu, report, schedule, specification, spreadsheet, one-pager, or\nimage. It is especially useful when that file changes over time or has many readers.\n\n## Mental model\n\n- **Site** - the company, venue, or account that owns pins. A connection may\n  reach one site or several.\n- **Pin** - a permanent public URL. The URL never changes.\n- **Version** - one uploaded file on a pin. A pin has at most one live\n  version; a new pin can have none. Older versions are archived, not deleted.\n- **Folder** - an organisational group for pins.\n- **Secure Access** - an optional Pro gate that collects contact details, requires\n  a PIN, or both before the live file opens.\n\n## The rule that matters most: staging is not publishing\n\nUploading with pinned_upload_file or pinned_stage_html creates a staged version.\nIt does not change the public file. Publishing is a separate action that makes the\nstaged version live and archives the previous live version. Restoring an archived\nversion also changes what the public sees.\n\nTreat publish and restore as public changes. Always inspect Secure Access and get\nexplicit confirmation immediately before either action.\n\n## Standard publish flow\n\n1. Find the site with pinned_list_sites. If there is more than one plausible site,\n   ask which one.\n2. Find the pin with pinned_list_pins. If the user wants a new permanent\n   link, create one with pinned_create_pin and a fresh idempotency_key.\n3. Check the effective gate with pinned_get_secure_access and tell the user if\n   viewers must provide contact details or a PIN.\n4. Stage the file with pinned_upload_file or pinned_stage_html using a fresh\n   idempotency_key. Set no public label — you may add an internal_label (private).\n   Staging returns a staged_preview_url: a draft gated to your team (NOT the public\n   link).\n5. Stop. Say the version is staged and not public, and give the user the\n   staged_preview_url to review. Ask whether to publish now or schedule it,\n   including the date, time, and timezone when scheduling.\n6. After explicit confirmation, call pinned_publish_version with a fresh\n   idempotency_key. By default it publishes with no label. Set internal_label for a\n   private team note, and only set external_label (the public label) when the user\n   explicitly asks for one. Return its permanent_link to the user.\n\n## Restore flow\n\n1. Call pinned_list_versions and identify the archived version.\n2. Call pinned_get_secure_access and explain the effective viewer gate.\n3. State that restoring will immediately replace the public file and archive the\n   current live version.\n4. Get explicit confirmation.\n5. Call pinned_restore_version only after confirmation.\n\n## More playbooks\n\n- **Update an existing link:** find pin, inspect Secure Access, stage, confirm,\n  publish, return permanent_link.\n- **Create a new link:** pinned_create_pin with idempotency_key, inspect Secure\n  Access, stage, confirm, publish.\n- **Schedule:** stage, confirm timestamp and timezone, then publish with\n  scheduled_for in ISO 8601 format.\n- **Organise:** pinned_create_folder with idempotency_key, then pinned_move_pin.\n- **Label:** versions default to no label. A version has two optional labels: an\n  internal_label (private team note, dashboard-only, never shown to viewers) and an\n  external_label (the public label shown to viewers). Set them on\n  pinned_publish_version, or change them later with pinned_relabel_version. Never\n  infer or auto-generate the external (public) label — set it ONLY when the user\n  explicitly asks for a public, customer-facing label. Staging sets no public label.\n- **Read content:** pinned_get_file_content with version_id (or pin_id for the pin's\n  current live version) returns HTML and CSV as inline text you can read or edit; PDF,\n  DOCX, XLSX, and images come back as a short-lived signed URL to fetch. It reads the\n  original uploaded file and works even on Secure Access pins (owner access).\n\n## Secure Access (Pro)\n\nAlways call pinned_get_secure_access before publishing or restoring. The effective\npolicy may come from the pin, its folder, or the site default.\n\npinned_set_secure_access supports:\n\n- contact: collect name, email, and/or phone. Name must be paired with email or phone.\n- pin: require a 4-6 digit PIN.\n- pin_contact: require both.\n- inherit: true: remove the pin override and use the folder/default policy.\n\nThe tool requires either inherit: true or an explicit enabled value so an inherited\ngate cannot be disabled accidentally. If the plan does not include Secure Access,\nrelay that plainly and do not retry.\n\n## Idempotency\n\nCreate, upload, prepare, complete, and publish operations require idempotency:\n\n- MCP: idempotency_key in the tool input.\n- REST: Idempotency-Key header.\n\nUse a fresh key for each logical action. Reuse the same key only to retry the exact\nsame action with the exact same payload. A changed payload with the same key returns\n409 and must not be retried with that key.\n\n## Limits and supported files\n\n- Supported: PDF, DOCX, XLSX, CSV, PNG, JPEG, WebP, and self-contained HTML.\n- Maximum decoded file size: 20 MB.\n- Metadata JSON bodies: 64 KiB maximum. Direct uploads and MCP allow the larger\n  request size needed for one inline file.\n- Unsupported: PPTX, plain text, Markdown, video, and other formats. Export a deck\n  to PDF before staging it.\n- Integration limit: 300 requests/minute per IP before authentication, then 120\n  requests/minute per authenticated principal. Direct uploads are also limited to\n  20/minute. MCP batches may contain at most 25 calls.\n- A 429 response includes Retry-After. Wait before retrying.\n\n## Good operating behaviour\n\n- Never imply that an upload changed the public file.\n- Never publish or restore without explicit confirmation.\n- Always check and disclose Secure Access before publishing or restoring.\n- Always return permanent_link after publishing or creating a pin.\n- Ask one focused question when site, pin, timing, or intent is ambiguous.\n- Relay plan and validation errors plainly instead of retrying blindly.\n"}}
