River MCP
Give your assistant a workspace.
Connect Claude, ChatGPT, Cursor, or any AI assistant to River.
Your assistant can then work in your documents, sheets, and files, and hand big jobs to River’s AI. Everything it makes stays in your River.

Set up River for me. River is my AI workspace, and it has an MCP server. 1. Add River's MCP server, named "river". It's a remote (HTTP) MCP server at: https://api.meetriver.com/mcp If you can't add it yourself, tell me where it goes in your settings. 2. Connect to it. River opens a sign-in page where I enter my email and the code River emails me. 3. Call get_workspace and follow River's setup guide. Instructions: https://meetriver.com/mcp/docs

A few things to know.
What is MCP?
MCP, the Model Context Protocol, is the open standard AI assistants use to work with other apps. River’s MCP gives your assistant River’s tools, once you sign in.
What is River?
River is the AI workspace: documents, sheets, presentations, files, email, and calendar, with River’s AI to do the work. Use it on the web, or as an app for Mac, Windows, and Linux.
Do I need a River account first?
No. Signing in with your email makes your account. River emails you a code to confirm it’s you.
Which assistants work with River?
Claude, ChatGPT, Claude Code, Codex, Cursor, VS Code, Windsurf, Zed, Gemini CLI, and any other assistant that can add an MCP server by its address.
What will my assistant ask me to do?
Only the steps that need you: signing in, paying for a plan, and approving connections like Gmail. It brings each one to you with a link.
What does it cost?
The same as River. Work your assistant asks for uses your plan’s AI allowance, and your assistant can send you a link to pay.
Is my work private?
Yes. Your work is encrypted in transit and at rest, and River never uses it to train AI. Your assistant sees what it reads in River, so its own app’s privacy terms cover that.
