Excel for AI agents

Microsoft Excel is a spreadsheet application for organizing data, running calculations, and building charts and pivot tables, used across nearly every business function for tracking and reporting. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

03 · HOW IT WORKS

Excel in three steps.

01Your users connect ExcelThey sign in to Excel on Arc0 Connect, under your brand, and approve the access you ask for.
02You set the rulesReads run, writes like “create Workbook” can wait for the user, and “delete Table Row” can be denied outright.
03Any agent can actYour agent calls Excel through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.

POLICY.TS

await arc0.policies.set('excel', {
  read: 'allow',
  write: 'ask',        // create_workbook
  destructive: 'deny',  // delete_table_row
})

# Claude Code: the same connection, one URL
$ claude mcp add --transport http arc0 \

04 · AUTH AND DATA

How Excel connects.

Users sign in to Excel on Arc0 Connect and approve the scopes you request. Build with Arc0’s Excel OAuth app, or bring your own so the Excel consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

The same Excel connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Excel and Arc0, answered.

Q01

Can I use Excel with Claude, ChatGPT or Cursor?

Yes. Connect Excel to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Excel actions you allow.

Q02

How do users connect Excel?

Q03

Which Excel actions can my agent take?

55 in total: 27 read, 21 write and 7 destructive, such as “create Workbook”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Excel?

Yes. Actions like “delete Table Row” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Excel too?

Yes. The same Excel connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
