OpenSIN Tool Engine: 42 Production-Ready Tools, API Server & CLI

Today we're releasing the most comprehensive AI coding agent tool system ever built — 42 production-ready tools, a full API server with OpenAI-compatible endpoints, and a standalone CLI that connects to it all.

What's New

42 Tools (Claude Code Parity + More)

We've built every tool that Claude Code has, plus the unique OpenSIN features that no one else offers:

Core Tools: Bash (with sandbox), FileRead, FileEdit, FileWrite, Glob, Grep Web Tools: WebFetch, WebSearch (DuckDuckGo, no API key) AI Tools: Agent (sub-agent orchestration), Skill loading Productivity: TodoWrite, Config, Sleep, StructuredOutput, NotebookEdit System: PowerShell, REPL, KillShell, TaskOutput, GetErrors Workflow: ScheduleCron, Plan Mode, Worktree, Brief, Switch Mode Team: TeamCreate, TeamDelete, TeamUpdate, TeamMessage MCP: McpAuth, ReadMcpResource, ListMcpResources Utility: Help, Status, Version, RemoteTrigger, ToolSearch

Full API Server

The OpenSIN API server provides OpenAI-compatible endpoints alongside powerful tool management:

  • Tool Engine — Execute, search, and list all 42 tools
  • Session Management — Create, resume, list, and delete sessions
  • MCP Integration — Connect and manage MCP servers
  • Compaction — Context summarization with auto-compact
  • Permissions — Granular 5-tier permission system
  • OpenAI Compatible — Drop-in /v1/chat/completions endpoint
  • Health Checks — Basic, detailed, ready, and live probes
  • Rate Limiting — Token bucket with API key tiers
  • Input Validation — XSS and path traversal protection

Standalone CLI

The OpenSIN CLI connects to the API server with three modes:

# Interactive REPL
opensin --api-url http://localhost:8000

# Single query
opensin "Read src/main.py" --api-url http://localhost:8000

# Pipe mode
echo "Find all Python files" | opensin --api-url http://localhost:8000

Getting Started

1. Start the API Server

cd opensin_core
pip install -e .
uvicorn opensin_core.api_server.server:app --reload --port 8000

2. Use the CLI

cd OpenSIN-Code/packages/opensin-sdk
npm install && npm run build && npm link
opensin --api-url http://localhost:8000

3. Or Use the API Directly

curl http://localhost:8000/api/tools/list
curl -X POST http://localhost:8000/api/tools/execute \
  -H "Content-Type: application/json" \
  -d '{"tool_name": "bash", "params": {"command": "echo hello"}, "workspace": ".", "session_id": "test", "permission_mode": "allow"}'

What Makes OpenSIN Different

  1. Fully Open Source — Apache 2.0 license, no black boxes
  2. 42 Tools — Complete Claude Code parity
  3. Multi-Provider — OpenSIN, OpenAI, Anthropic support
  4. Swarm Integration — Multi-agent orchestration built-in
  5. Voice — Gemini S2S integration
  6. Cron — Natural language scheduling
  7. Provider Routing — AI-optimized multi-provider routing
  8. Fleet Dashboard — Real-time monitoring
