Month end means invoices in five vendor portals, receipts in a folder and an expense form to fill in. Cowork reads and writes the files in your trusted folders.

Cuiar signs in to the portals with the vault, downloads the invoices and types the expense lines. Cowork renames and files what comes back, and you check the result.

Five vendor portals in Cuiar tabs on the left. Invoice files move one by one from the portals into a folder named Invoices 2026-10 on the right, and each file takes its new name.

Setup

Connect Cuiar, then trust a folder.

Cowork uses the connectors of your Claude account. It does not read Claude Code's settings.

Route

The connector is how Cowork reaches your tabs.

Cowork runs its commands on Anthropic's servers. The remote MCP server is the one route that reaches the Cuiar app on your computer.

Remote MCPmcp.cuiar.com/mcp
Best fit
A custom connector with OAuth, on every paid Claude plan.
Local MCPcuiar mcp
Not tested
Claude Desktop starts local servers. Anthropic does not say if Cowork tasks use them.
CLIcuiar exec
No
Cowork's shell is on Anthropic's servers, away from your computer.
Routineson a schedule
Works
A watch that must run on your computer fits a Cuiar routine. Cowork's scheduled tasks reach Cuiar while the app is open.

Example tasks

Month-end work, split in two

  • 01

    Collect vendor invoices

    “Sign in to our five SaaS vendor portals, download the October invoices, rename them vendor-2026-10.pdf and move them to ~/Finance/Invoices/2026-10.”

    Cuiar downloads. Cowork renames and files.

  • 02

    Enter expense lines

    “Read the receipts in ~/Receipts/October. For each one, add an expense line in our expense portal with date, amount, category and merchant. Stop before Submit.”

    Cowork reads the receipts. Cuiar types the lines.

  • 03

    Fill in a timesheet

    “Use my hours in ~/Work/hours-week-44.xlsx and enter them in the client's timesheet portal day by day. Ask me before you submit the week.”

  • 04

    Update the CRM

    “For each row in leads.xlsx, open the contact in our web CRM in my Work workspace. Set the stage and the next-step date from the sheet. List the rows you could not match.”

  • 05

    Build the Monday report

    “Every Monday at 7:30, export last week's ticket statistics as CSV from the helpdesk portal and build a one-page summary in ~/Reports.”

    A Cowork scheduled task. The Cuiar app must be open at 7:30.
