Connect your agent to 700+ apps through One. One MCP server, three tools, 80,000+ actions with real API documentation, no OAuth tokens to manage.
Write integration code against a third-party API (Gmail, Stripe, Shopify, HubSpot, QuickBooks, Slack, Salesforce and 700+ more) using that API's real schema instead of a guessed one. Use when building a feature that calls an external SaaS API, adding an OAuth connection to an app, generating a client or webhook handler, or debugging an integration that returns 400 or 401.
Read and write real data in third-party apps (Gmail, Slack, Stripe, Shopify, HubSpot, QuickBooks, Linear, Notion, Salesforce and 700+ more) through the One MCP server. Use when the user asks to send an email, post a message, look up a customer, pull invoices, create a ticket, sync records, or take any action in an external SaaS app, even if they never say "One".
