Excel Add-in

Supercharge your spreadsheets

Main Sequence maintains an official, open-source Excel plugin that lets users consume and interact with platform data directly from spreadsheets.
DataNodes become live, trusted data sources — bringing real-time, enterprise-grade data into a familiar interface without manual exports or version drift.

Artificial Intelligence

Interact with natural language

The Main Sequence SDK, combined with the platform’s unified framework, allows any function or method to be automatically exposed as an agentic tool — with no extra setup or maintenance.
Because workflows, data, and infrastructure are abstracted and standardized, LLM-assisted agents can execute complex operations or surface insights to business users in seconds.

Main Sequence, Your Enterprise AI Backbone

Main Sequence enables engineering teams and business users to turn their work into agentic tools by bridging daily operations with AI automation. Its Data Engine enriches every DataNode with metadata and a unified structure for smarter interactions, while the platform provides a secure, governed foundation for enterprise-scale AI adoption.

Existing pricing logic, data, and optimization models can be instantly exposed as MCP endpoints for internal or external AI agents, allowing organizations to build LLM-assisted workflows without consultants or system rewrites.
