Works with your AI agent

Keep using the AI you already talk to. Connect Claude, ChatGPT, Grok, Cursor or any other app that supports MCP, and it can search your stash, work your tasks and pages, read your files, and, with your say-so, use your browser. The same key works in every app.

What your AI can do with Multify

Once it's connected, you can ask your AI app for things it couldn't reach before:

• What you've saved. Search your Stash: the links, posts, videos and quotes you saved from around the web.
• Your work. Create, move and finish tasks, file them into projects, and play runbooks.
• Your notes. Read and write Pages and the preferences Multify remembers about you.
• Your files. Read what's in Files and save new PDFs and images there.
• Your browser. Open sites, read them signed in, and fill forms in a tab behind yours, with your approval. See Let your agent use your browser.
• One key for every app. The same key works in all of them, and you can see and cut off each connection from one page.

Get your key

Your key lives on the MCP page of your Multify account.

Claude

The Claude desktop app reads its MCP servers from a config file. The steps below set that up. To use Claude on the web instead, add a custom connector in Claude's settings and paste the URL with your key (step 4 above) as the server address.

{
  "mcpServers": {
    "multify": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://api.multify.co/mcp",
        "--header",
        "Authorization: Bearer YOUR_BRIDGE_API_KEY"
      ]
    }
  }
}

ChatGPT

ChatGPT adds MCP servers as custom connectors. Where that lives depends on your plan, and OpenAI renames the menu from time to time, so look in Settings for Connectors (or Apps & Connectors). Some plans need developer mode turned on under the advanced settings before you can add your own.

Grok

Grok connects to MCP servers from its Connectors page, with no config file.

Cursor

Cursor has MCP support built into its settings.

{
  "mcpServers": {
    "multify": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://api.multify.co/mcp",
        "--header",
        "Authorization: Bearer YOUR_BRIDGE_API_KEY"
      ]
    }
  }
}

Other apps

Any MCP app that connects over HTTP or SSE works. The Multify MCP endpoint accepts an Authorization: Bearer header, an x-api-key header, or the key on the server URL as ?api_key=.

VS Code (GitHub Copilot)

VS Code uses a different format from Claude and Cursor. Add this to your settings.json (open it via Ctrl+Shift+P → Preferences: Open User Settings (JSON)) inside the "mcp" section:

{
  "mcp": {
    "servers": {
      "multify": {
        "url": "https://api.multify.co/mcp",
        "type": "http",
        "headers": {
          "Authorization": "Bearer YOUR_BRIDGE_API_KEY"
        }
      }
    }
  }
}

Windsurf

In Windsurf go to Settings → MCP → Add MCP Server and paste the same mcpServers config used for Claude/Cursor (shown in the Cursor section above). The config file lives at ~/.codeium/windsurf/mcp_config.json.

Perplexity

In Perplexity go to Settings → AI → Connectors → Add MCP server. Enter https://api.multify.co/mcp as the server URL, and add an Authorization header with the value Bearer YOUR_BRIDGE_API_KEY. If Perplexity only has a URL box and no header field, paste https://api.multify.co/mcp?api_key=YOUR_BRIDGE_API_KEY as the server URL instead.

Any other client

For any other MCP client that supports HTTP or SSE transport:

• Server URL: https://api.multify.co/mcp
• Authentication: pass your Bridge API Key as Authorization: Bearer YOUR_BRIDGE_API_KEY, or as an x-api-key header
• Or put the key on the URL: https://api.multify.co/mcp?api_key=YOUR_BRIDGE_API_KEY
• Protocol version: 2024-11-05

Available tools

You don't need to name these. Ask in plain words and your AI app picks the tool. The tables are here so you know what's possible.

Drive a connected browser

Your AI app can open sites in your own browser, read them as you'd see them signed in, and click, type and fill forms in a tab behind the one you're using. You turn it on per browser in the extension, or for every browser at once with the account default in the web app or Stash, and you approve each site the first time. Paying, booking, agreeing to terms and sending a message always ask you first. Setup, approvals and limits are on Let your agent use your browser.

Sessions and security

Each time an AI app connects to Multify, it shows up as a session. You can view and manage active sessions from your MCP settings page.

• Session ID is returned in the x-multify-mcp-session-id response header. Apps that keep it avoid opening duplicate sessions.
• Last active updates every time that session makes a request
• Revoke next to any session cuts off that app right away, without changing your key

Troubleshooting

Tools not showing up in my client

Check that the key was pasted with no extra spaces. Then open a new chat, since some apps only load tools when a conversation starts. Also confirm you have Node.js installed if your client is using npx mcp-remote.

Getting an authentication error

Double-check the key on your MCP page and use the copy button so nothing gets mistyped. If you regenerated your key, update it in every app that uses it.

File tool returns no results

Open Files in your Multify account to see what's there. If it's empty, upload a file and then try again from your MCP client.

My agent says no browser is connected

The browser has to be open, signed in to the same Multify account as your key, and switched on under Settings → Outside agents in the extension, or by your account default in the web app or Stash. A browser you turned off in the extension stays off until you turn it on there again. See Let your agent use your browser.
