 Use `--list` to see the list of available tools, or see below.
 
+### Code execution
+
+If you specify `--tools=code` to the MCP server, it will expose just two tools:
+
+- `search_docs` - Searches the API documentation and returns a list of markdown results
+- `execute` - Runs code against the TypeScript client
+
+This allows the LLM to implement more complex logic by chaining together many API calls without loading
+intermediary results into its context window.
+
+The code execution itself happens in a Deno sandbox that has network access only to the base URL for the API.

 ### Specifying the MCP Client
 
 Different clients have varying abilities to handle arbitrary tools and schemas.
