Nanobot

Framework for converting MCP servers into autonomous AI agents with UI

Nanobot transforms MCP servers into full autonomous agents by adding a planning layer, conversation memory, and web-based UI on top of MCP tool capabilities. It enables building agents that combine multiple MCP servers with LLM reasoning to complete multi-step tasks. Features MCP-UI for browser-based interaction and supports any MCP-compatible tools as agent capabilities.

About Nanobot

Nanobot bridges the gap between MCP servers that provide individual tool capabilities and autonomous agents that can chain multiple tools together to accomplish complex tasks. The framework wraps MCP server tools with an LLM-powered planning layer that decides which tools to invoke, in what order, and how to use results from one tool as inputs to the next. This transforms a collection of standalone MCP servers into a coordinated agent system.

The MCP-UI component provides a browser-based interface for interacting with Nanobot agents, making the agent capabilities accessible without requiring CLI interaction or API integration. Users can chat with agents, observe their tool usage in real-time, review execution plans, and provide guidance during multi-step task execution. This visual interface makes agent capabilities accessible to non-technical users.

Nanobot supports any MCP-compatible tool as an agent capability, meaning the growing ecosystem of MCP servers becomes the agent's toolbox. A Nanobot agent with GitHub, database, and web search MCP servers can autonomously research a topic, create issues in a repository, and update documentation without human intervention for each step. The conversation memory enables context that persists across interactions for ongoing task management.

Explore categories, tags & use cases

AWS open-source SDK for building model-driven AI agents

Strands Agents is an open-source SDK from AWS that takes a model-driven approach to building AI agents. Developers define a prompt, model, and tools, and the LLM handles planning and orchestration autonomously. Supports Amazon Bedrock, Anthropic, OpenAI, Gemini, Ollama, and more. Powers Amazon Q Developer and AWS Glue in production. Available in Python and TypeScript with native MCP support.

Open Source

Self-hosted MCP gateway for managing multiple servers behind a single endpoint

MCPJungle is a self-hosted gateway that aggregates multiple MCP servers behind a single endpoint. It provides server discovery, health checking, access control, and request routing so AI clients connect to one gateway rather than managing individual server connections. Supports server grouping, authentication, and monitoring dashboards for production MCP deployments.
