+## Plugin tools
+
+Other opencode plugins can register custom tools (e.g. `opencode-pty`'s
+`pty_spawn`, `context-mode`'s `ctx_execute`). With `forwardPluginTools: true`
+(default), this plugin **mirrors those tools to the Cursor agent** via a local
+stdio MCP server (`opencode-plugin-tools`) that is added to the forwarded
+`mcpServers`. When the Cursor agent calls one, the call runs through the
+plugin's *real* implementation inside opencode's runtime — same code path
+opencode itself uses.
+
+How it works:
+
+1. At startup (and re-checked each turn) the plugin reads your `plugin: []`
+   list, re-imports each plugin from the opencode package cache, and reads its
+   `tool` map. Plugins that can't be imported are skipped and logged once.
+2. A loopback-only HTTP control channel (random port, per-session bearer
+   token) connects the MCP child process to the host plugin, which owns the
+   tool closures. Nothing is reachable from outside the machine.
+3. The Cursor agent sees the tools through its normal MCP surface and calls
+   them like any other MCP tool.
+
+### Permissions
+
+Mirrored calls are evaluated against your opencode `permission` config,
+keyed by the tool id — with the same semantics opencode itself uses:
+permission keys are wildcard-matched, and every pattern a tool's `ask`
+requests is matched against the rule's pattern; the **last** matching rule
+wins. `~`/`$HOME` prefixes in patterns expand against your home directory.
+
+- **`allow`** → runs without prompting (every requested pattern must allow).
+- **`deny`** → rejected.
+- **`ask`** (or no rule) → rejected with a clear message. The interactive
+  prompt is anchored to opencode's session/TUI and can't be surfaced to the
+  Cursor agent, so ask-permissioned tools are withheld rather than run
+  unattended. Set the tool to `allow` to use it from Cursor:
+
+```json
+{ "permission": { "pty_spawn": "allow", "ctx_*": "allow" } }
+```
+
+Pattern-scoped rules work too — e.g. allow spawning ptys only under `/tmp`
+(specific patterns must come **after** the wildcard they narrow):
+
+```json
+{ "permission": { "pty_spawn": { "*": "ask", "/tmp/*": "allow" } } }
+```
+
+If a tool's execution calls `ask` internally and no gate is available, the
+call fails closed.
+
+### Filtering
+
+```json
+{
+  "provider": {
+    "cursor": {
+      "options": {
+        "forwardPluginTools": true,
+        "pluginTools": {
+          "include": ["pty_*"],
+          "exclude": ["ctx_execute"]
+        }
+      }
+    }
+  }
+}
+```
+
+`include` keeps only matching tool ids (wildcards supported); `exclude` always
+drops. `forwardPluginTools: false` disables the bridge entirely.
+
+### Limitations
+
+- Plugins that fail to re-import under the bridge (e.g. native modules that
+  only load under Bun, or plugins that throw when initialised twice) are
+  skipped and reported in the opencode log; their tools stay unavailable to
+  Cursor. Skills and MCP servers from those plugins are unaffected.
+- Tool definitions are snapshotted at startup and re-checked per turn; a
+  plugin installed mid-session is picked up on the next turn.
+- `cursor_cloud_agent` targets a remote repo and does not inherit plugin
+  tools.
