One remote MCP server. Every account you connect.

To connect Claude to your email and calendars, add Prubex as a custom connector and sign in through Prubex. You choose what Claude may do and which accounts it reaches, and the connector then works in every Claude app you use.

1. 1

   In Claude, open Settings, then Connectors, and choose to add a custom connector.

2. 2

   Name it Prubex and paste this URL:

   https://mcp.prubex.com/mcp

   Copy
3. 3

   Choose Connect. Claude opens Prubex: sign in, choose what it may do (Assistant is recommended) and which accounts it reaches, then choose Allow. Leave “Ask me before it sends anything” on, and sends wait for your approval in Prubex.

4. 4

   Back in Claude, ask something like “What came in from Ana this week?”. Sends come back as “waiting for approval” until you approve them in Prubex.

To connect Claude Code to your email and calendars, add Prubex as an HTTP MCP server at https://mcp.prubex.com/mcp. Sign in through the browser, or use an API key made in Prubex under Agents & keys.

1. 1

   Add the server:

   claude mcp add --transport http prubex https://mcp.prubex.com/mcp

   Copy
2. 2

   In Claude Code, run /mcp, choose prubex and authenticate: your browser opens Prubex’s consent screen.

3. 3

   Or, with an API key instead of signing in:

   claude mcp add --transport http prubex https://mcp.prubex.com/mcp --header "Authorization: Bearer pbx_live_YOUR_KEY"

   Copy

To connect ChatGPT to your email and calendars, add Prubex as a connector and sign in through Prubex. ChatGPT also gets search and fetch, the two tools deep research uses to read across your mail and calendars.

1. 1

   In ChatGPT, open Settings, then Apps and connectors. If adding your own needs it, turn on developer mode under Advanced settings.

2. 2

   Create a connector named Prubex with this URL and OAuth sign-in:

   https://mcp.prubex.com/mcp

   Copy
3. 3

   ChatGPT opens Prubex: sign in, choose a preset and accounts, then Allow. Prubex shows ChatGPT as verified when it signs in with its published identity.

4. 4

   Use it in a chat, or in deep research: “Find every invoice from Contoso this quarter and summarise them.”

To connect Cursor to your email and calendars, add Prubex to Cursor’s MCP settings with an API key made in Prubex. Cursor’s agent then works across every account you connect, with your approval rules applied.

1. 1

   Create an API key in Prubex under Agents & keys. Choose Assistant and keep “Require approval for every send” on: sends then wait for your approval.

   Create an API key
2. 2

   Add this to ~/.cursor/mcp.json (or the project’s .cursor/mcp.json), replacing pbx_live_YOUR_KEY with your key:

   {
     "mcpServers": {
       "prubex": {
         "url": "https://mcp.prubex.com/mcp",
         "headers": {
           "Authorization": "Bearer pbx_live_YOUR_KEY"
         }
       }
     }
   }

   Copy
3. 3

   Open Cursor’s settings, then MCP, and check that prubex shows its tools.

To connect VS Code to your email and calendars, add Prubex as a remote MCP server in mcp.json. GitHub Copilot’s agent mode can sign in through Prubex, or send an API key.

1. 1

   Add this to .vscode/mcp.json in your project (or your user mcp.json):

   {
     "servers": {
       "prubex": {
         "type": "http",
         "url": "https://mcp.prubex.com/mcp"
       }
     }
   }

   Copy
2. 2

   Start the server from the file’s code lens. VS Code asks to sign in, and opens Prubex’s consent screen.

3. 3

   Or send an API key instead:

   {
     "servers": {
       "prubex": {
         "type": "http",
         "url": "https://mcp.prubex.com/mcp",
         "headers": {
           "Authorization": "Bearer pbx_live_YOUR_KEY"
         }
       }
     }
   }
