Built-in Plugins

OpenBot comes with several built-in plugins that provide essential functionality for agents.

Core Plugins

storage

The storage plugin provides agents with access to local files, conversation history (channels and threads), and long-term memories.

• Usage: Automatically loaded by many agents to maintain context.
• Capabilities: CRUD operations on threads, reading/writing files in the workspace.

ui

The UI plugin handles the rendering of interactive widgets in the OpenBot client.

• Widgets: Messages, choices, forms, and status lists.
• Events: Listens for client:ui:widget events to display content to the user.

mcp

The Model Context Protocol (MCP) plugin allows OpenBot to connect to external MCP servers, expanding the tools available to agents.

• Configuration: MCP servers are defined in ~/.openbot/config.json.
• Integration: Seamlessly maps MCP tools to agent capabilities.

ai-sdk

The AI SDK plugin provides a runtime for agents powered by the Vercel AI SDK.

• Models: Supports various providers (OpenAI, Anthropic, etc.) as configured in the agent’s AGENT.md.
• Streaming: Handles the streaming of agent responses back to the event bus.

delegation

The delegation plugin allows agents to hand off tasks to other agents.

• Workflow: Enables complex multi-agent orchestrations where specialized agents collaborate on a single task.
