Agent workflows for Smartsheet.

01

List sheets

Use when discovering accessible sheet IDs. Returns one bounded page of metadata; follow nextPage until null. Not for reading cell contents.

02

Get sheet

Use when inspecting sheet columns and a bounded page of rows. Filter rowIds and columnIds for targeted reads. totalRowCount covers the sheet; no owner or writer details are requested.

03

Get row

Use when reading one known row or checking an uncertain row write. Returns cells without writer or contact-object expansions; not a search action.

02 · ACTIONS

10 Smartsheet actions, graded by risk.

These actions come from the Arc0 registry. Your identity, provider permissions and Arc0 policies determine which actions can run.

read

6

Look things up, subject to your permissions.

  • smartsheet.list_sheets
    List sheets

    Use when discovering accessible sheet IDs. Returns one bounded page of metadata; follow nextPage until null. Not for reading cell contents.

  • smartsheet.get_sheet
    Get sheet

    Use when inspecting sheet columns and a bounded page of rows. Filter rowIds and columnIds for targeted reads. totalRowCount covers the sheet; no owner or writer details are requested.

  • smartsheet.get_row
    Get row

    Use when reading one known row or checking an uncertain row write. Returns cells without writer or contact-object expansions; not a search action.

  • smartsheet.list_workspaces
    List workspaces

    Use when discovering workspace IDs and access levels. Returns up to 100 metadata entries, the vendor minimum page size. Pass lastKey to continue; not for workspace contents.

  • smartsheet.search_sheet
    Search sheet

    Use when finding IDs matching text inside one sheet. Returns at most 50 structural hits; truncated signals omitted matches. Search indexing can lag writes, so use get_row for verification.

  • smartsheet.list_row_discussions
    List row discussions

    Use when locating a discussion ID on a specific row before replying. Returns bounded discussion metadata without comments or author details; follow nextPage until null.

write

3

Create and change things. Allow, or ask the user first.

  • smartsheet.add_rows
    Add rows

    Use when appending up to ten rows to a sheet. Sheet automations may notify collaborators. Not for updates. After an uncertain result, read back before retrying to avoid duplicate rows.

  • smartsheet.update_rows
    Update rows

    Use when setting supplied cells on up to ten known rows. May trigger sheet automation notifications; not for moving or creating rows. Read back after uncertain writes before retrying.

  • smartsheet.add_comment
    Add comment

    Use when replying to a known row discussion as the connected user. Visible to sheet collaborators; followers and mentioned people may be notified. Not for private notes. Inspect the thread after an uncertain result before retrying.

destructive

1

Delete, cancel or archive. Ask first, or deny outright.

  • smartsheet.delete_rows
    Delete rows

    Use when explicitly removing known rows, including disposable test rows. Deleting a parent also removes its children. Not for routine updates; verify uncertain deletion before retrying.

03 · POLICIES AND AUDIT

Control access to Smartsheet.

After early access is enabled, connect the intended Smartsheet account, authorize your AI client and set policies for its tools.

Provider permissions and Arc0 policy both apply. Allow reads, require approval for selected writes, or deny destructive actions. The audit log records execution decisions.

Configure policies and approvals

Example policy choices

  • Read actions: allow where authorized
  • smartsheet.update_rows: require approval
  • smartsheet.delete_rows: deny

04 · AUTH AND DATA

How Smartsheet connects.

Connect Smartsheet using API key. OAuth grants the provider scopes shown during consent; API keys and other credentials retain the permissions configured at the provider. Arc0 stores credentials in its encrypted vault and does not pass them to the model. Disconnect to remove access through Arc0; revoke a key at the provider to invalidate it there. Token refresh and provider-side revocation depend on the authentication lane and provider.

The connection serves authorized calls through Arc0 MCP and REST. How Arc0 handles credentials →

05 · AI CLIENTS

Use Smartsheet with your AI client.

Request access to Smartsheet first. An Arc0 administrator must enable it for your organization before these actions appear. Then authorize your AI client separately. It only receives tools and accounts allowed for that identity.

Smartsheet with Any MCP client

Streamable HTTP

  1. Use a client that supports remote MCP over Streamable HTTP. Add the server URL below and choose OAuth.
  2. For a client without OAuth, use a self-bound API key with execute permission in the X-API-Key header. Store it in secret storage or an environment variable, outside source control. Never send both an API key and an OAuth bearer token.
  3. Use the MCP clients guide for the SDK transport example and Embedded identity for business-managed end users.
https://api.arc0.ai/mcp
Full MCP setup and troubleshooting

After setup, ask your agent to find an allowed read action, load its schema, and execute it on the intended account. Check Activity for the receipt. A connected MCP client alone does not confirm a successful provider call.

07 · FAQ

Smartsheet and Arc0, answered.

Q01

Does Smartsheet work with Claude Desktop and Claude Code?

Yes, after early access is enabled for your organization and you connect the intended account. Use Arc0’s remote MCP endpoint with OAuth. Claude Code has a documented registration command; Desktop uses the generic remote-client setup.

Q02

Can I use Smartsheet with OpenAI Codex, ChatGPT and Cursor?

Yes, after early access is enabled for your organization and you connect the intended account. Codex and ChatGPT have setup instructions in Arc0’s MCP clients guide. Cursor uses the generic remote-MCP steps. Tool access remains scoped to the authorized identity.

Q03

Is this the official Smartsheet MCP server?

This is Arc0’s integration page, not a claim of an official Smartsheet server. Arc0 adds a shared connection, policy and audit experience across apps. Consult Smartsheet for its own current MCP offerings.

Q04

Which Smartsheet actions are supported?

10 registry-defined actions: 6 read, 3 write and 1 destructive. Provider permissions, access enablement and Arc0 policy determine what can execute.

Q05

Which permissions does Smartsheet need?

Connect Smartsheet using API key. OAuth grants the provider scopes shown during consent; API keys and other credentials retain the permissions configured at the provider. Arc0 stores credentials in its encrypted vault and does not pass them to the model. Disconnect to remove access through Arc0; revoke a key at the provider to invalidate it there. Token refresh and provider-side revocation depend on the authentication lane and provider.

Q06

Can I restrict writes in Smartsheet?

You can deny write and destructive actions or require approval. Provider scopes and Arc0 action policies are separate controls; a policy does not grant additional provider permissions.

Q07

What does Smartsheet through Arc0 cost?

See Arc0 pricing for current connectivity plans. The provider may require its own subscription or charge per request. Arc0 plan allowances do not make third-party data or paid actions free.
