+# HubSpot
+
+Cursor plugin that connects agents to [HubSpot](https://www.hubspot.com) through HubSpot's official remote [Model Context Protocol](https://modelcontextprotocol.io/) server.
+
+Search and update CRM records, work with activities and conversations, and manage marketing email drafts in the signed-in HubSpot account.
+
+This is HubSpot's remote CRM MCP server — not the [developer MCP server](https://developers.hubspot.com/docs/developer-tooling/local-development/developer-mcp/setup), which helps build apps and CMS assets locally.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **HubSpot**.
+3. Click **Install**, then set the client ID and secret (below) and complete the HubSpot sign-in prompt.
+
+Or run `/add-plugin hubspot` in chat.
+
+## MCP
+
+```json
+{
+  "mcpServers": {
+    "hubspot": {
+      "type": "http",
+      "url": "https://mcp.hubspot.com",
+      "auth": {
+        "CLIENT_ID": "${CLIENT_ID}",
+        "CLIENT_SECRET": "${CLIENT_SECRET}"
+      }
+    }
+  }
+}
+```
+
+## Setup
+
+HubSpot's remote MCP server requires a dedicated MCP auth app with OAuth (PKCE). An administrator or developer has to create that app before anyone can connect.
+
+1. In HubSpot, go to **Development → MCP Auth Apps** (or open [app.hubspot.com/l/mcp-auth-apps](https://app.hubspot.com/l/mcp-auth-apps/)) and click **Create MCP auth app**.
+2. Register both redirect URLs on that app:
+   - Desktop: `http://localhost:8787/callback`
+   - Web and Cloud Agents: `https://www.cursor.com/agents/mcp/oauth/callback`
+3. In **Dashboard → Plugins → Configure**, set **HubSpot Client ID** and **HubSpot Client Secret** from that app.
+4. Complete the HubSpot OAuth login when Cursor prompts. Select the account to connect and grant permissions.
+
+On a team marketplace an admin sets the client ID and secret once for everyone; each member still completes their own HubSpot OAuth login, so tool calls run with that member's HubSpot permissions.
+
+Scopes are not declared on the app up front — they come from the MCP server's available tools and the permissions the installing user grants. If HubSpot adds tools later, users may need to reinstall to pick up new scopes.
+
+## Notes
+
+- If the HubSpot account has Sensitive Data turned on, activity objects and conversation data are blocked through the MCP server (this does not affect the standard CRM APIs).
+- Help desk conversations are visible to all users; conversations-inbox access follows the same team/user restrictions as in HubSpot.
+
