MCP support

Agents can now connect to external tool servers using the Model Context Protocol. Any MCP-compatible server can provide tools to your workflows without custom integration — databases, APIs, internal services, anything with an MCP server.

​
Web search and web fetch

Two new built-in tools bring real-time information into workflow decisions. web_search queries the Brave Search API, and web_fetch retrieves web pages, converting HTML to Markdown and summarizing long content to fit within context limits.

​
CLI backends

Individual workflow nodes can now delegate work to external AI coding assistants. Set the backend to claude-code, codex, or gemini-cli and the node will use that CLI tool instead of the built-in agent loop. 
implement [handler=codergen, cli_backend=codex]
review [handler=codergen, cli_backend=claude-code]
This means each stage in a workflow can use a different AI tool — use Codex for implementation and Claude Code for review, for example.

​
Subagent tools

Agents can spawn sub-agents to handle focused tasks in parallel, each with their own tool set and conversation context. The parent agent delegates work and receives results without its own context window growing.
