Watched how we used GPT-5 and Claude Code with nano-agents here.
Multi-Provider Support: Seamlessly switch between OpenAI (GPT-5), Anthropic (Claude), and Ollama (local models)
File System Operations: Read, write, edit, and analyze files autonomously
Nested Agent Architecture: MCP server spawns internal agents for task execution
Unified Interface: All providers use the same OpenAI SDK for consistency
Experiment Ready: Decent testing, error handling, and token tracking
Easy Integration: Works with Claude Desktop, or as a CLI
read_file
Read file contents
write_file
Create or overwrite files
get_file_info
Get file metadata (size, dates, type)
edit_file

Clients mentioned in this server's README:

microsoft/playwright
Playwright is a framework for web automation and testing. It drives Chromium, Firefox, and WebKit with a single API — in your tests, in your scripts, and as a tool for AI agents.

yamadashy/repomix
Repomix is a tool that packs a codebase into an AI-friendly format, supporting local and remote repository processing and providing code compression, security checks and multiple output formats.

bytedance/UI-TARS-desktop
TARS is ByteDance's multimodal AI agent stack, shipping two projects: Agent TARS (a CLI and Web UI agent built on MCP) and UI-TARS-desktop (a desktop GUI agent).

ahujasid/blender-mcp
formerly blender-mcp — the PyPI package is now mcp-for-blender. Existing setups keep working; no config change is required. Read more.

microsoft/playwright-mcp
A Model Context Protocol (MCP) server that provides browser automation capabilities using Playwright. This server enables LLMs to interact with web pages through structured accessibility snapshots, bypassing the need for screenshots or visually-tuned models.

comet-ml/opik
Opik is the open-source LLM observability and evaluation platform for AI agent tracing, LLM evaluation, prompt management, and production monitoring. Built by Comet. Apache-2.0 licensed, free to self-host the full platform, with 20,000+ GitHub stars.
