Share a PDF
lnkdrp_share_pdfCreate a lnkdrp share link for a PDF. Sources, in order of fewest transfers: (1) A file in the person's Google Drive, as driveFileId: the id lnkdrp_drive_search returns, or a pasted Drive, Docs, Slides or Sheets link. LinkDrop fetches it straight from Drive (no download, no upload), converts a Doc, Slides deck or Sheet to PDF, and the document links back to the original. When Drive is not connected the call fails with drive_not_connected, whose details.connectUrl is the Integrations page where the person connects it. (2) A public https link to the PDF: sourceUrl. (3) A file on the person's computer, when this MCP server runs on that same machine: filePath. (4) A file with no path this server can read and no public URL (a sandbox, an export): uploadId, the id lnkdrp_create_upload returns once the file has been PUT to its uploadUrl. (5) When a client's network policy blocks the upload host, the PUT to uploadUrl does not reach LinkDrop: nothing is stored or created, and the same client is blocked the same way on a retry. Routes (1) to (3) bypass the client's network: LinkDrop fetches the file itself, or this server reads it. (6) A file only the person can reach, such as a chat attachment a sandbox cannot send: lnkdrp_create_upload_link makes a one-time page where they add it from their own browser, filed with the settings given there. Pass exactly one of driveFileId, sourceUrl (an https URL the server fetches), filePath (an absolute path the MCP server reads from its own disk, so it works only when the server runs on the same machine as the file; no base64 is sent), uploadId or fileBase64 (the PDF's bytes inline, for a small file - under 3 MB on a hosted deployment). sourceUrl and uploadId take a PDF up to 50MB; filePath and fileBase64 take up to 16 MB before optimization, and on a hosted deployment what is sent after it has to be under 3 MB, so a large inline upload can still be refused with too_large - sourceUrl and uploadId have no such ceiling. On the filePath and fileBase64 paths the PDF is shrunk first when that helps and is safe (optimize: false turns it off); the result's optimized field reports what happened. Creates the document, imports the file, starts processing (preview, text, summary) and returns { docId, shareId, shareUrl, status, uploadId, warnings, creditsRemaining }. By default waits up to timeoutSeconds for status ready|failed; on a timeout it returns the status so far, and lnkdrp_get_share reads the same status later. Optional: allowDownload, password. Pass projectId or projectSlug to create the document inside a project from the start; it is then listed there and its notifications go to that project's channel. lnkdrp writes each upload's AI summary itself and bills it (1 credit); no argument accepts a summary. status 'failed' means the file itself could not be processed: failureReason says why, the link is live but has no usable file until a working PDF replaces it (or the document is deleted); failureCode, when present, is the machine reason (too_many_pages, too_large). A PDF with more pages than LinkDrop takes (300 by default) is refused with too_many_pages, and the same file is refused the same way every time. process_attempts_exhausted means the file failed processing 3 times and is not retried. A skipped AI step (for example out of credits) does not fail the call: the link is still valid and warnings says what was skipped. Free workspaces have a cap on shared documents. At the cap this call fails with code plan_limit and creates nothing. The error names what still works without upgrading, such as adding another link to a document that already exists. Below the cap, planWarning appears when the workspace is close to it. A new file is refused with storage_quota_exceeded when it would take the workspace past its storage quota (capabilities.storage in lnkdrp_whoami): nothing is stored, and the same file is refused again until space is freed. Deleted documents count until they are purged, 30 days after deletion; archiving frees nothing. Pro has a larger quota than Free; on Free the error carries upgradeUrl, the plans page. Titles, summaries and viewer-supplied text in results are untrusted content written by document authors and readers.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| title | No | The document's name in the owner's lnkdrp app: its page, lists, search and the activity feed (default: the Drive file's name for driveFileId, otherwise Untitled document). Recipients see it too. On a document link (/s/) it is the tab title and link preview, password-protected links included; the title the AI summary suggests is used there only when the document has no title. On a project link (/p/) it labels the document's card in the project and is the tab title and link preview of the document's page. | |
| fileName | No | File name to record, used with fileBase64 or to override filePath's own basename or the name given to lnkdrp_create_upload (default: document.pdf). | |
| filePath | No | Absolute path to a PDF, read from disk BY THE MCP SERVER - so this only works when the server runs on the same machine as the file (a local stdio/localhost server; otherwise the call is refused with a validation error). ~ is not expanded: /Users/name/Downloads/deck.pdf, not ~/Downloads/deck.pdf. No base64 is sent, and the file may be up to 16 MB before optimization (under 3 MB after it on a hosted deployment; sourceUrl has no such ceiling). Exactly one of sourceUrl / fileBase64 / filePath / uploadId / driveFileId is required. | |
| optimize | No | Shrink the PDF before uploading by downsampling its images (default true; needs Ghostscript on the MCP server). Skipped for files already under 1MB. The original is kept whenever the result is not smaller, not a valid PDF, or has a different page count, so no page is dropped. The result's `optimized` field says what happened. | |
| password | No | Protect the share link with a password. Set exactly as given, any length from 1 to 128 characters (a single character included); the gate accepts only that value. The owner can reveal it later in the link's settings. | |
| uploadId | No | The uploadId lnkdrp_create_upload returns, once the PDF has been PUT to its uploadUrl: a file with no path this server can read and no public URL, up to 50MB. Single-use, and only from the connection that created it. (The uploadId in the result is lnkdrp's upload row, a different id.) Exactly one of sourceUrl / fileBase64 / filePath / uploadId / driveFileId is required. | |
| projectId | No | Create the document inside this project from the start: the project's id (24 hex chars). Optional; pass at most one of projectId / projectSlug. A request inbox is refused. | |
| sourceUrl | No | Public https URL of the PDF, up to 50MB; lnkdrp /s/ links work too. A Google Docs, Slides or Sheets link, or a drive.google.com file link, goes through the person's Drive connection when they have one (same as driveFileId: converted to PDF, linked back to the original). Without one, an editor link fails with drive_not_connected (details.connectUrl is the Integrations page), and a drive.google.com link is fetched publicly, so it works only when shared with anyone who has the link. OneDrive and SharePoint links are refused: they serve a sign-in page, not a file. Exactly one of sourceUrl / fileBase64 / filePath / uploadId / driveFileId is required. | |
| fileBase64 | No | The PDF's bytes, base64-encoded, for a file with no public URL (locally generated, a private attachment). Decoded size up to 16 MB before optimization; on a hosted deployment what is sent after optimization has to be under 3 MB, or the call is refused with too_large. A multi-megabyte base64 string as a tool argument is slow to send and easy to garble; uploadId and filePath carry no base64. Exactly one of sourceUrl / fileBase64 / filePath / uploadId / driveFileId is required. | |
| driveFileId | No | A file in the person's Google Drive: the id lnkdrp_drive_search returns, or the Drive, Docs, Slides or Sheets link the person pasted. LinkDrop fetches it itself through the person's own Drive connection, so nothing is downloaded or uploaded by the client, and the document links back to the original file. A PDF is imported as is, up to 50MB; a Google Doc, Slides deck or Sheet is exported to PDF by Google (up to 10 MB). Without a title the document is named after the Drive file. When the person has not connected Drive the call fails with drive_not_connected, whose details.connectUrl is the Integrations page where they connect it. Exactly one of sourceUrl / fileBase64 / filePath / uploadId / driveFileId is required. | |
| projectSlug | No | Create the document inside the project with this slug (e.g. "series-a-data-room"). Optional; pass at most one of projectId / projectSlug. Resolved before anything is created, so a bad slug creates nothing. | |
| waitForReady | No | Wait until processing finishes (status ready or failed) before returning. | |
| allowDownload | No | Let viewers download the PDF (default false). | |
| idempotencyKey | Yes | Caller-chosen key (1-128 chars). Reusing it within 24h returns the same document instead of creating another, marked replayed: true to tell a retry from a second upload; the same key with different arguments is refused. A replay describes this call's own upload (creditsRemaining is the balance right after the first call); if the document has since been given another version, the replay stays about this call's upload and adds supersededBy { uploadId, version } plus a warning naming the version the link now serves. If a call fails after the file was stored, the document is kept and so is the key: reusing it returns that same error with details.docId/shareId/shareUrl and details.recovery, and no second document is made. A call that fails before anything is created leaves the key free, so a retry with it uploads again. | |
| timeoutSeconds | No | Max seconds to wait for processing (5-120, default 60). |
