Smartsheet’s MCP Server Goes Multi-Platform: ChatGPT, Microsoft Copilot, and Gemini Join Claude, Plus a New In-App AI Companion

Under the hood, the server exposes over 30 tools that let an AI agent read from and write to Smartsheet . A custom LLM-first serialization layer helps reduce token usage by approximately 33%, a detail that matters for organizations running frequent, complex enterprise workflows that would otherwise rack up significant AI costs . Access to the MCP Server requires a Smartsheet Business, Enterprise, or Advance plan .

Smart Assist: AI That Lives Inside Smartsheet

For users who want AI assistance without leaving the Smartsheet interface, Smart Assist acts as a contextual companion embedded in the top-right corner of the platform . It understands the content of whatever sheet or workspace is open and can summarize data, find specific information, track recent changes, create and update work items, manage comments, explore connected workspaces, and even generate dashboards and charts from a chat prompt .

Smart Assist became generally available on June 3, 2026, and is included in Smartsheet Pro, Business, Enterprise, and Advanced Work Management plans . It is currently available for Commercial US, Commercial EU, and Commercial AU environments .

Availability: A Closer Look at the Rollout

Smartsheet’s official press release and documentation state that the MCP Server, along with connections to Anthropic’s Claude and Google Cloud Gemini Enterprise, are available to all customers globally . The same sources describe connections to Microsoft Copilot and ChatGPT as also announced on June 11 .

However, one report from IT Brief UK adds a regional nuance not present in Smartsheet's own materials. According to that source, while Smart Assist, the MCP Server, and connections to Claude and Google Cloud Gemini Enterprise are available now, the specific integrations for Microsoft Copilot and ChatGPT are available to US customers at launch and are due to roll out to other regions in the future . Smartsheet’s own documentation pages do not mention any phased regional restrictions for these new connections .

Here is what the available information indicates about general availability and plan requirements:

• Smart Assist: Generally available as of June 3, 2026. For Commercial US, EU, and AU on Pro, Business, Enterprise, and Advance plans .
• MCP Server for Anthropic's Claude: Generally available since March 24, 2026. Requires a Business, Enterprise, or Advance plan .
• MCP Server for Google Cloud Gemini Enterprise: Available globally as of June 11, 2026. Requires a Business, Enterprise, or Advance plan plus a Gemini Enterprise license .
• MCP Server for ChatGPT: Available globally as of June 11, 2026, per Smartsheet ; one external source suggests a US-first phased international rollout . Requires a Business, Enterprise, or Advance plan .
• MCP Server for Microsoft Copilot: Available globally as of June 11, 2026, per Smartsheet ; one external source suggests a US-first phased international rollout . Requires a Business, Enterprise, or Advance plan plus a Microsoft Copilot license .

The Bigger Picture: Open Protocols Over Proprietary Lock-In

The June 11 announcement is the strongest signal yet of Smartsheet’s bet on vendor-agnostic AI interoperability. Rather than building separate, proprietary integrations for every new AI assistant that enters the enterprise, Smartsheet adopted Anthropic’s open Model Context Protocol standard and built a single MCP Server that any compliant client can use . This means an organization could let one department use Claude for analysis, another use Copilot inside Microsoft 365, and a third experiment with Gemini, all operating against the same live work data without duplicating work or rebuilding integrations .

Smartsheet CPTO Pratima Arora framed the problem the company is solving bluntly: “The problem most teams run into isn't access to AI. It's that their AI has no idea how their organization actually works” . By making Smartsheet the “live operational data layer” for enterprise AI, the company aims to make the AI assistant itself interchangeable .

The early adoption numbers suggest demand is real. Since the MCP Server launched in March 2026, Smartsheet reported over 22,000 unique users and 3 million AI actions, with nearly one in three of those actions creating or modifying live work rather than just reading data .

In an industry where enterprises are growing wary of being locked into a single AI provider’s ecosystem, Smartsheet’s protocol-based approach taps into a larger movement toward standards like MCP and Agent-to-Agent protocols that let different AI systems work together over a unified data fabric. The message is clear: choose any assistant you want, as long as you know exactly what is happening inside your organization.
