Workspace369 MCP server

Workspace369 MCP server

The official remote Model Context Protocol server for Workspace369: CRM, proposals, e-sign contracts, invoices, projects, calendar and time tracking for your AI apps.

Workspace369 is the all-in-one workspace for businesses that deliver client work: CRM, proposals, contracts and e-signature, invoices and payments, projects and tasks, calendar and booking, time tracking, a shared inbox and workflows.

Connect Claude, ChatGPT, Cursor, VS Code, Windsurf or any MCP client to your Workspace369 workspace. The AI app can then look up a client, draft an invoice or proposal, schedule work, log time or reply to a lead in plain language. Every call runs as you, within your own permissions.

• Transport: Streamable HTTP
• Auth: OAuth sign-in with your Workspace369 account (no API key to paste). Scripts and agents that can't open a browser use a personal access token.
• Hosted by Workspace369. Nothing to install or run locally.

This repository holds the public listing metadata (server.json) and connection docs. The server itself is operated by Workspace369 LLC and is not open source.

Connect

Claude (claude.ai, Desktop): add a custom connector with the URL, then sign in.

ChatGPT: on plans that offer developer mode, add a custom connector (app) with the URL, then sign in.

Cursor / Windsurf (mcp.json):

{
  "mcpServers": {
    "workspace369": {
      "url": "https://mcp.workspace369.com/mcp"
    }
  }
}

VS Code (.vscode/mcp.json):

{
  "servers": {
    "workspace369": {
      "type": "http",
      "url": "https://mcp.workspace369.com/mcp"
    }
  }
}

Claude Code:

claude mcp add --transport http workspace369 https://mcp.workspace369.com/mcp

VS Code (command line):

code --add-mcp '{"name":"workspace369","type":"http","url":"https://mcp.workspace369.com/mcp"}'

When the app connects, Workspace369's sign-in page opens. Choose the workspace and set an access level for each area (None, View, Edit, Edit and send, and so on). The app never gets more than you approve. A workspace admin must first turn MCP on under Settings → AI Connections (MCP).
