Show available AI providers based on configured environment variables.

🤖 AI Provider Configuration Available providers (based on env vars): ✅ openai ✅ anthropic Override with env vars or CLI flags: AI_PROVIDER=openai|anthropic AI_MODEL=gpt-4o|claude-sonnet-4-20250514|etc. --provider openai --model gpt-4o

🤖 AI Provider Configuration Available providers (based on env vars): ⚠️ No API keys found! Set one of these environment variables: - OPENAI_API_KEY → Use OpenAI (gpt-4o, gpt-4-turbo, etc.) - ANTHROPIC_API_KEY → Use Anthropic (claude-sonnet-4-20250514, etc.)

Lyra analyzes tools and automatically selects from 8 plugin templates:

The AI follows this priority order when selecting templates:
- MCP Detection→ If tool uses@modelcontextprotocol/sdk:

- Has HTTP server →mcp-http
- Has bin entry →mcp-stdio

Lyra Tool Discovery is part of a larger automation toolchain for the SperaxOS ecosystem:

- Discovery(this tool) — Finds tools on GitHub/npm, analyzes with AI, generates configs
- Conversion—github-to-mcpconverts repos to MCP servers
- Registry—plugin.deliveryhosts the plugin marketplace
- Consumption— SperaxOS users discover and install plugins
