+# Statsig
+
+Cursor plugin that connects agents to [Statsig](https://statsig.com) through Statsig's official remote [Model Context Protocol](https://modelcontextprotocol.io/) server.
+
+Look up feature gates, experiments, dynamic configs, and metrics in the signed-in Statsig project, read experiment results, and create or update configs when your Statsig role allows writes.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **Statsig**.
+3. Click **Install**, then complete the Statsig sign-in prompt.
+
+Or run `/add-plugin statsig` in chat.
+
+## MCP
+
+```json
+{
+  "mcpServers": {
+    "statsig": {
+      "type": "http",
+      "url": "https://api.statsig.com/v1/mcp"
+    }
+  }
+}
+```
+
+Auth is OAuth against Statsig. Cursor prompts for Statsig user login when the plugin connects — there is no API key or client ID to configure.
+
+## Before you connect
+
+- You need a Statsig account with access to a project.
+- Statsig MCP OAuth only supports **Personal Console API Keys**. Your Statsig org owner must enable Personal Console API Key creation for your role under organization settings before the OAuth sign-in will succeed.
+- Read-only Statsig users can use all read tools. Write tools require a role with write permissions on the project.
+
+## What agents can do
+
+| Category | Capabilities |
+| --- | --- |
+| Feature gates | List, inspect, create, and update gates and their rules |
+| Experiments | List and inspect experiments, read setup and results, create and update experiments |
+| Dynamic configs | List, inspect, create, and update dynamic configs |
+| Metrics | Look up metrics and metric definitions used by gates and experiments |
+| Project | Inspect the signed-in project's configuration |
+
+The hosted runtime is the source of truth for tool names and schemas.
+
+## Notes
+
+- Tool calls run as the Statsig user who authorizes the connection and cannot exceed that user's project role.
+- Statsig hosts the server itself; this plugin does not wrap a local stdio server or `mcp-remote`.
+- Statsig also documents an API-key setup via `npx mcp-remote` with a Console API key header. This plugin uses the OAuth setup only.
+- Revoke access at any time by deleting the Personal Console API Key from your Statsig account settings.
