MCP SERVER · OFFICIAL PROJECTTrack MASV deliveries from both sides — packages the team sent and packages clients uploaded to a Portal — replay the events behind any transfer, and move files between MASV and connected storage such as AWS S3, Frame.io or Dropbox.
LABSCO SUMMARY
An activity keeps only its current state — pending, started, complete, cancelled or error — so get_activity_events, which returns each transition it went through, is where a stalled transfer actually explains itself. Inventory has to be assembled from both lists, because packages sent by the team and packages uploaded to Portals are kept apart. Destruction is gated separately from the API key, which is the right default for a tool an agent drives: an expired package and its files are deleted rather than archived.
A server over the MASV managed file transfer API, covering packages, Portals, the activity feed and connected cloud or on-premise storage integrations. MASV describes it as experimental: it has not been through their internal verification process, and support is best effort.
A MASV team account: MASV_TEAM_ID and MASV_API_KEY. It runs straight from npx, so nothing is installed. Deletion is off by default — delete_package and delete_portal only work with MASV_ALLOW_DELETE set to true.
One command plus a key — npx @getmasv/masv-mcp-server, then supply credentials
USE CASES
Find the package on the Portal side, then read the activity and its transitions — the current state alone will not say where it stopped.
Pull both lists, because the team's own sends and the Portal uploads are kept separately, then open the ones you care about.
Create the portal with a name and subdomain, then tighten it — access code, download password, file-type restrictions — and add the team members who should see it.
Check which integrations are connected, then send the package on to the S3 bucket, Frame.io project or Storage Gateway that should hold it.
Browse the integration for the files and their IDs, then pull them into MASV as a new package rather than downloading them first.
Move the expiration date and time, or switch unlimited storage on for it, before the files are deleted for good.
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
create_portalCreate a new portal for collecting files from external users. Portals can be configured with access codes, download passwords, file type restrictions, custom branding, connected integrations, and more. Only 'name' and 'subdomain' are required - all other settings are optional.
delete_packageDelete a package by ID. This permanently removes the package and all its files and cannot be undone. Requires MASV_ALLOW_DELETE=true environment variable to be set.
delete_portalDelete a portal by ID. This permanently removes the portal and cannot be undone. Packages that were uploaded to this portal will remain accessible. Requires MASV_ALLOW_DELETE=true environment variable to be set.
get_activitiesGet activities. Activities are records of events that happened with MASV resources like packages, links and transfers. Each activity has assosiated events and can be in one of several states: pending, started, complete, cancelled, error. Full list of activity types: package_upload_to_masv (package upload from user or connected storage integration to MASV), package_download_from_masv (user downloads package), link_generation (new download link is added to the package), package_transfer_masv_to_cloud (package transfer from MASV to connected storage integration)
get_activities_informationGet detailed information about all existing activities and their accurate states description. Always use this tool provide users with detailed explanation about activities and their states.
get_activity_eventsGet history of events for given activity. Activity gets event record every time it transitions to a new state. It is very useful to get events history to get more information about activity because it can transition states several times and activity only keeps track of its current state.
get_integrationsGet list of connected integrations. Integration could be cloud or on-prem system like AWS S3, Frame.io, Dropbox, MASV Storage Gateway and many others
get_packageGet package by id
get_package_filesGet list of package files
get_package_transfersGet all transfers of a package to storage. Transfer is a package delivery via MASV to cloud or on-premise (via MASV Storage Gateway) destination
get_packagesGet team packages. These are packages sent by MASV team users directly to MASV. It does not include packages sent to Portals. To get full list of packages you need to get both team packages and portal packages
get_portalGet a specific portal by ID. Returns detailed information about the portal including its configuration, recipients, connected integrations, and settings.
get_portal_packagesGet portal packages. These are packages uploaded by anyone to MASV Portals. Only packages that were uploaded to Portals returned by this tool. To get full list of packages you need to get both team packages and portal packages.
get_portalsGet list of portals that belong to the team. Portals are used to collect files from external users. Each portal has a unique subdomain and can be configured with various settings like upload and download password, file type restrictions, connected integrations, metadata forms, etc.
get_team_membersGet list of all team members. Returns member details including id (membership_id), email, name, policy, approval status, and teamspaces. Use this to get membership IDs needed for portal access_list when creating private portals.
list_files_on_integrationList files on any integration (cloud or MASV Storage Gateway). Supports pagination — if more results are available, a cursor is returned; pass it back in the next call to get the next page.
send_package_to_integrationSend MASV package to connected integration. Integration could be cloud or on-prem system like AWS S3, Frame.io, Dropbox, MASV Storage Gateway and many others
transfer_files_from_integrationTransfer files from a cloud integration (AWS S3, Azure, Dropbox, etc.) or MASV Storage Gateway to MASV. Creates a new package and initiates the transfer. Use list_files_on_integration first to get file information including IDs.
update_package_expiration_date_and_timeUpdate package expiration date and time. Also allows enable or disable unlimited storage. Additional package storage may incur charges, depending on your team subscription plan. Once expired the package and all of its files are deleted and can not be restored.
update_portalUpdate an existing portal's configuration. Use this to modify portal settings like access controls, branding, file restrictions, and more.
BEFORE YOU INSTALL
20 tools when we connected. list_files_on_storage_gateway is documented but not currently exposed. delete_package and delete_portal act only with MASV_ALLOW_DELETE=true; other writes such as create_portal and update_portal need no flag.
The documented client runs the server on your machine.
