Give OpenCode, the open-source terminal coding agent, live web search, extraction, crawling, and research through the official opencode-tavily plugin. The plugin drives the Tavily CLI.
1

Install the Tavily CLI

Or install it with Python: uv tool install tavily-cli or pip install tavily-cli.
2

If TAVILY_API_KEY is set in your environment, the plugin passes it through to shell commands.
3

Add the plugin

Add opencode-tavily to the plugin array in your opencode.json:

Or via npm:
4

Try it

Start OpenCode and ask a current-events question:
