+# HighLevel
+
+Cursor plugin that connects agents to [HighLevel](https://www.gohighlevel.com) (also branded LeadConnector) through HighLevel's official remote [Model Context Protocol](https://modelcontextprotocol.io/) server.
+
+Find and update CRM data in a HighLevel sub-account — contacts, conversations and messages, opportunities and pipelines, calendars and appointments, payments, blogs, email templates, and social posts.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **HighLevel**.
+3. Click **Install**, then complete the LeadConnector sign-in prompt.
+
+Or run `/add-plugin highlevel` in chat.
+
+## MCP
+
+```json
+{
+  "mcpServers": {
+    "highlevel": {
+      "type": "http",
+      "url": "https://services.leadconnectorhq.com/mcp/"
+    }
+  }
+}
+```
+
+Auth is OAuth with Dynamic Client Registration and PKCE. Cursor registers itself and opens the LeadConnector sign-in when the plugin connects: sign in, choose the sub-account (location) to expose, and approve. There is no Private Integration Token or `locationId` header to configure.
+
+## What agents can do
+
+Tools depend on the scopes granted to the connection. HighLevel's docs list tools in these areas:
+
+| Area | Example tools |
+| --- | --- |
+| Contacts | `contacts_get-contacts`, `contacts_get-contact`, `contacts_create-contact`, `contacts_update-contact`, `contacts_upsert-contact`, `contacts_add-tags`, `contacts_remove-tags`, `contacts_get-all-tasks` |
+| Conversations | `conversations_search-conversation`, `conversations_get-messages`, `conversations_send-a-new-message` |
+| Opportunities | `opportunities_search-opportunity`, `opportunities_get-pipelines`, `opportunities_get-opportunity`, `opportunities_update-opportunity` |
+| Calendars | `calendars_get-calendar-events`, `calendars_get-appointment-notes` |
+| Locations | `locations_get-location`, `locations_get-custom-fields` |
+| Payments | `payments_get-order-by-id`, `payments_list-transactions` |
+| Blogs | `blogs_get-blogs`, `blogs_get-blog-post`, `blogs_create-blog-post`, `blogs_update-blog-post` |
+| Email templates | `emails_fetch-template`, `emails_create-template` |
+| Social posts | `socialmediaposting_get-posts`, `socialmediaposting_create-post`, `socialmediaposting_edit-post`, `socialmediaposting_get-social-media-statistics` |
+
+The hosted runtime is the source of truth for tool names and schemas.
+
+## Notes
+
+- The server can write as well as read — including sending messages, updating contacts and opportunities, and creating posts. Approve only the access agents need, and test on a non-production sub-account first.
+- Each connection works against the sub-account chosen at sign-in.
+- HighLevel also publishes client-specific OAuth endpoints for Claude (`/mcp/anthropic/v2`) and OpenAI clients (`/mcp/openai/v2/`) that expose a broader operation catalog through a small set of unified tools. This plugin uses the universal endpoint.
