What is the plain MCP server?
Plain is the AI support stack built for B2B teams. Composable infrastructure that gives you complete flexibility to build a support motion that grows with your business — no-code or all-code.
How do I connect plain to my AI agent?
Use the remote MCP URL on this page in your MCP client (Claude, Cursor, VS Code, and more). Copy the endpoint if your client needs a manual entry, then complete provider sign-in when your client connects — tools appear after authentication.
How many tools does plain provide?
This endpoint requires provider sign-in, so MCPBundles could not list tools anonymously during the last probe. After you connect and authenticate in your MCP client, your session should receive the live tool list from the provider.
What authentication does plain require?
plain may require signing in to the provider before tools can run. Connect through MCPBundles or your MCP client and complete any provider login when prompted.
