Gigasheet for AI agents
Gigasheet is a spreadsheet-style interface for exploring and cleaning very large datasets. Data and operations teams use it to analyze big files without a database. 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.
What agents do in Gigasheet.
Append new rows to a dataset
Add a fresh batch of exported rows to an existing dataset so it stays current for analysis.
Count rows matching a filter
Count how many rows in a dataset match a condition, as a read-only check before running a bigger job.
Build a formula column
Create a formula column that flags rows meeting a business rule, like orders over a spend threshold.
150 Gigasheet actions, graded by risk.
Every Gigasheet action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

Gigasheet in three steps.
- 01Your users connect GigasheetThey add their Gigasheet api key on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, writes like “send MCP Request to Sheet Assistant” can wait for the user, and “delete sheet or folder by handle” can be denied outright.
- 03Any agent can actYour agent calls Gigasheet through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('gigasheet', { read: 'allow', write: 'ask', // create_mcp destructive: 'deny', // delete_delete_handle }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How Gigasheet connects.
Users add their Gigasheet api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.
The same Gigasheet connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →
- AUTH
- API key
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES
- Results only, never credentials
- AUDIT LOG
- Every call, on every plan

Gigasheet and Arc0, answered.
Can I use Gigasheet with Claude, ChatGPT or Cursor?
Yes. Connect Gigasheet 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 Gigasheet actions you allow.
How do users connect Gigasheet?
Users add their Gigasheet api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.
Which Gigasheet actions can my agent take?
150 in total: 59 read, 74 write and 17 destructive, such as “send MCP Request to Sheet Assistant”. Your policies decide which of them each agent may call.
Can I stop my agent from deleting things in Gigasheet?
Yes. Actions like “delete sheet or folder by handle” 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.
Can my own backend call Gigasheet too?
Yes. The same Gigasheet connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Gigasheet into your agent.
Your users connect Gigasheet once, under your brand. Your agent gets 150 actions behind your policies, with every call on the record.
