+### Install the OpenCode plugin
+
+This is the OpenCode equivalent of the Claude Code Stop hook. It listens for idle sessions and writes a deferred-capture JSONL file for the daemon to drain.
+
+```bash
+mkdir -p ~/.config/opencode/plugins
+cp deploy/opencode/iai-mcp-capture.js ~/.config/opencode/plugins/
+```
+
+Make sure `@opencode-ai/plugin` is installed:
+
+```bash
+cd ~/.config/opencode
+npm install @opencode-ai/plugin
+```
+
+### Connect OpenCode
+
+Add the MCP server to `~/.config/opencode/config.json`:
+
+```json
+{
+  "mcp": {
+    "iai-mcp": {
+      "type": "local",

+
+Use the absolute path to `mcp-wrapper/dist/index.js`. The plugin file (`iai-mcp-capture.js`) must already be in `~/.config/opencode/plugins/`.

 Claude Code is the primary host, validated in daily use.
 
+OpenCode is supported via the `iai-mcp-capture.js` plugin (see Install the OpenCode plugin above) and MCP server config in `~/.config/opencode/config.json`.

 Claude Desktop should work (uses `claude_desktop_config.json` instead of `~/.claude.json`) but hasn't been tested end to end.
 
 Other MCP-over-stdio hosts speak the same protocol and should work in principle. Not tested.
