MaSH is the scripting layer underneath Foldr automations. Plain-text scripts with a version history and a diff built in. The same engine also drives Mashup, the visual block editor, and Grace, the verbal route via the AI assistant. Three surfaces, one runtime. Engineers and IT admins read and edit the same file.
set supplier to mash.search(file.name) file.fields.supplier = supplier.name
MaSH ships with object types for files, shares, fields, search, Captur, HTTP, SMTP, SQL, PDF (including redaction), Office documents and spreadsheets, barcodes, addresses and postcodes, Microsoft 365 and Google, AI and crypto. Most useful automations are a few lines of MaSH and a trigger.
A PDF lands in /Invoices/Inbox. MaSH reads the supplier, files it under the right folder, fills the custom fields, emails the buyer for approval.
Every Monday at 6am, sweep the Captur queue, escalate anything older than seven days, post a summary to wherever your team reads such things (email, SMS, or an HTTP call to your chat tool).
Aggregate custom fields across hundreds of shares. “Total invoiced this quarter” runs the same regardless of which storage backends the files live on.
HTTP, SMTP, SQL, PDF generation, encryption and key signing, and AI calls. MaSH ships with object types for the things integrations actually need.
A script runs as the person who wrote it and sees only what they could see. It can’t reach your database or anything inside our network, and every run has a time limit, because we’d rather a runaway loop stopped than took the queue with it. A script Grace drafts gets a risk check first.
Every save keeps a version you can compare, and every run records what it changed. Forms and approvals can run a script, too: a form comes in, a script files it.
The MaSH engine has three surfaces. Pick whichever fits the task or the person at the keyboard; switch between them on the same workflow without rewriting it.
Drag blocks together to build a workflow. Every block is a real MaSH instruction, not an opaque no-code shape. Open the same workflow as text and the script is right there.
Plain-text scripts with a version history and a diff built in, and a Flow bundle you can keep in git if you like. The surface engineers reach for first.
Ask the AI assistant in plain English to build, change or run a workflow. Grace writes the MaSH for you and shows you the result before anything runs in earnest.
A Foldr Flow packages a MaSH script alongside the share it operates on, the custom fields it reads, the Captur templates it depends on. Import it on another Foldr and you’ll see what will be created, renamed or skipped before anything changes. Accounts for the storage aren’t in the file, so you’ll point each share at its own credentials.
Read about FlowThe same scripts run on Foldr Cloud and on your own appliance. Cloud keeps sensible limits on run time, mail volume and which hosts a script can call, since the workers are shared; on an appliance you set those yourself. MaSH comes with Business and Enterprise on Foldr Cloud, and as a licence on your own appliance. Run history is kept for a week on Business and a month on Enterprise.
