# OpenCode

> Connect OpenCode to Darwin Browse.

Add Darwin to OpenCode, select an executable Search result, then start one Act thread.

## First request

Once Darwin's tools appear in the agent, paste this request:

```text theme={null}
Search Darwin for an executable capability for
this task. Show the best result and its terms.
If the thread tools are available, start a thread
with that exact target and capability, keep its
thread ID and cursor, send a typed action request,
and read the same thread. Stop for any requested
confirmation, connection, payment, or approval.
```

<Steps>
  <Step title="Connect Darwin">
    Add Darwin to `opencode.json`, reload MCP, and complete browser OAuth only when a protected operation needs it.

    ```json theme={null}
    {
      "$schema": "https://opencode.ai/config.json",
      "mcp": {
        "darwin": {
          "type": "remote",
          "url": "https://mcp.darwin.so/mcp",
          "enabled": true
        }
      }
    }
    ```

    **Success:** OpenCode lists Darwin's tools without a credential in the repository.
  </Step>

  <Step title="Search and choose a result">
    Search for an executable capability. Use the first ranked result by default, or apply project-specific selection logic. Keep its exact `agent` and nested `capability` identifiers.

    **Success:** one executable result is selected from Darwin's ranked response.
  </Step>

  <Step title="Start a thread and request work">
    Call `start_thread` with the result's `agent` as `targetAgent`, plus `messageType` and `messageContent`; optionally set `agent`, `capability`, and a stable `idempotencyKey`. Keep the returned `thread` and `cursor`, then read progress with `get_thread`.

    **Success:** Darwin returns a durable thread ID and ordered history. Acceptance is not delivery or completion.
  </Step>
</Steps>

<Warning>
  Terminal or repository access is not Darwin authority. Always follow the caller's scopes and the exact typed requests,
  revisions, and operation states returned in the thread.
</Warning>

Review OpenCode's [MCP guide](https://opencode.ai/docs/mcp-servers/) for its current configuration format.
