AgentOS - Universal Agent Runtime

PyPI version License: MIT Python 3.10+

AgentOS is an open-source universal agent runtime designed for the multi-agent era. It provides a unified execution environment where AI agents can discover, install, and compose skills from a decentralized marketplace, while connecting to any MCP-compatible tool server.

pip install nexus-agentos

Why AgentOS?

Problem AgentOS Solution
Agents siloed in different frameworks Universal runtime — one env runs OpenClaw, LangChain, custom agents
No marketplace for agent skills Built-in Skill Market — devs upload, users install, admins review
MCP servers fragmented 8 built-in MCP servers, 34 tools out of the box
No TUI for agent management Terminal UI (Textual) — file browser, skill manager, task runner
Hard to compose multi-agent workflows Sub-agent dispatch — agents delegate to specialists automatically

Quick Start

1. Install

pip install nexus-agentos

# Or from source
git clone https://github.com/wuyifeishu/nexus-agentos.git
cd nexus-agentos && pip install -e .

2. Launch the Skill Marketplace

python -m agentos.server.marketplace_platform

Open http://localhost:8899/static/platform.html — you'll see the full marketplace with:

  • Browse: search/discover 64 built-in skills across 11 categories
  • Login/Register: JWT auth for developers
  • Upload: zip your skill with a skill.yaml manifest
  • Review: admin panel for security scanning, approve/reject

3. Run the Terminal UI

python -m agentos.desktop

Ctrl+M opens the Market Panel. Ctrl+F opens File Browser. Full keyboard-driven.

Built-in MCP Servers

Server Tools Description
filesystem 7 read_file, write_file, list_directory, search_files, get_file_info, create_directory, move_file
webfetch 3 fetch_url, fetch_json, check_url
memory 6 store_memory, retrieve_memory, search_memory, list_categories, delete_memory, update_memory
search 4 web_search, news_search, image_search, suggest

Skill Marketplace Platform

A production-ready marketplace for the AgentOS ecosystem:

For Developers

  • Register/login with email & password (bcrypt + JWT)
  • Upload .zip skill packages with skill.yaml/manifest.json
  • Automatic security scanning on upload: dangerous imports, shell injection, obfuscation, hardcoded keys, excessive permissions
  • Track downloads and reviews
  • Developer profile pages

For Users

  • Browse/search skills by name, category, tags
  • One-click install from any ecosystem source
  • Rate and review installed skills

For Admins

  • Review queue with security findings per skill
  • Approve/reject with comments
  • Skill quality and safety enforcement

API Endpoints

POST   /api/auth/register          - Create developer account
POST   /api/auth/login             - Login, receive JWT
GET    /api/skills                 - Browse/search published skills
GET    /api/skills/{id}            - Skill detail
GET    /api/skills/{id}/download   - Download skill zip
POST   /api/skills/upload          - Upload new skill (auth required)
GET    /api/my/skills              - My uploaded skills
GET    /api/developers/{username}  - Developer profile
POST   /api/admin/review/{id}      - Approve/reject (admin)
GET    /api/admin/review-queue     - Pending reviews (admin)
GET    /api/categories             - Category listing

Security Scanning

Every uploaded skill is automatically scanned for:

Check Severity Description
Dangerous imports Critical os.system, subprocess, socket, ctypes
Shell injection Critical os.system(), eval(), exec(), __import__()
Code obfuscation High Base64-encoded payloads, eval chains
Hardcoded secrets High API keys, tokens, passwords in source
File permission escalation Medium chmod 777, os.chown
Network exfiltration High Suspicious requests.post to unknown hosts

Roadmap

  • Universal Agent Runtime
  • 64 Built-in Skills
  • 8 MCP Servers (34 tools)
  • Skill Marketplace with web UI
  • Developer registration & upload
  • Security scanning pipeline
  • Admin review queue
  • Terminal UI (TUI)
  • Multi-agent orchestration dashboard
  • Skill dependency resolution
  • Federated marketplace discovery
  • Blockchain-based skill provenance
