+    You can configure the Context7 MCP server in **Kilo Code** using either the UI or by editing your project's MCP configuration file.
+
+    Kilo Code supports two configuration levels:
+    - **Global MCP Configuration** — stored in `mcp_settings.json`
+    - **Project-level MCP Configuration** — stored in `.kilocode/mcp.json` (recommended)
+
+    **Via Kilo Code UI:**
+    1. Open **Kilo Code**
+    2. Click the **Settings** icon in the top-right corner
+    3. Navigate to **Settings → MCP Servers**
+    4. Click **Add Server**
+    5. Choose **HTTP Server** (Streamable HTTP Transport)
+    6. Enter URL: `https://mcp.context7.com/mcp`
+    7. Add Header - Key: `Authorization`, Value: `Bearer YOUR_API_KEY`
+    8. Click **Save**

+  <Accordion title="Emdash" icon="layer-group">
+    [Emdash](https://github.com/generalaction/emdash) is an orchestration layer for running multiple coding agents in parallel. Provider-agnostic, worktree-isolated, and local-first.
+
+    **What Emdash provides:**
+    - Global toggle: Settings → MCP → "Enable Context7 MCP"
+    - Per-workspace enable: The Context7 button in the ProviderBar (off by default). First click enables it for that workspace. Clicking again disables it.
+    - ProviderBar: The Context7 button shows status, a short explanation, and a link to docs
+
+    **What you still need to do:**
+    Configure your coding agent (Codex, Claude Code, Cursor, etc.) to connect to Context7 MCP. Emdash does not modify your agent's config. See the respective MCP configuration sections above for your agent.
+
+    See the [Emdash repository](https://github.com/generalaction/emdash) for more information.
