+# GlassFrog
+
+Cursor plugin that connects agents to [GlassFrog](https://www.glassfrog.com), the platform for Holacracy and role-based organizations, through GlassFrog's hosted [Model Context Protocol](https://modelcontextprotocol.io/) server.
+
+Read and update GlassFrog roles and accountabilities, projects and next actions, policies, tensions, and role channels.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **GlassFrog**.
+3. Click **Install**, then complete the GlassFrog sign-in prompt.
+
+Or run `/add-plugin glassfrog` in chat.
+
+## MCP
+
+```json
+{
+  "mcpServers": {
+    "glassfrog": {
+      "type": "http",
+      "url": "https://app.glassfrog.com/api/v5/mcp/core"
+    }
+  }
+}
+```
+
+Auth is OAuth 2.0 with dynamic client registration, so Cursor prompts for GlassFrog sign-in when the plugin connects — there is no client ID or API key to configure. On the approval screen, pick the organization to work in and the permissions to grant (usually **Everything I can access**), then click **Approve**.
+
+## Before you connect
+
+- Your GlassFrog organization needs **AI Integration** turned on. An organization admin turns it on in the organization settings; otherwise the organization is not listed when you connect.
+- You need a GlassFrog account in that organization.
+
+## What agents can do
+
+| Category | Capabilities |
+| --- | --- |
+| Roles | Look up roles, purpose, accountabilities, domains, and who fills them |
+| Work | List, create, and update projects and next actions |
+| Governance | Read policies and organization rules; raise tensions on roles |
+| Communication | Read and post to role channels; read and write role notes |
+
+The hosted runtime is the source of truth for tool names and schemas.
+
+## Notes
+
+- The connector acts with the access of the account that connects it, sees and changes only what that account can, and every change is attributed to it.
+- To disconnect, revoke the app in GlassFrog under your profile → **API** → **Connected apps**.
+
+## Docs
+
+- GlassFrog: https://www.glassfrog.com
+- MCP server docs: https://github.com/GlassFrog/glassfrog-mcp
+- Server URL: https://app.glassfrog.com/api/v5/mcp/core
+
+Logo is GlassFrog's frog mark from the `GlassFrog` GitHub organization. The submitted logo URL and glassfrog.com were unreachable when this plugin was added, so the file was not downloaded from the website.
