Protocols MAS-Lab speaks

MAS-Lab talks to the rest of the stack over open protocols. The agent, the team, and the experiment stay in YAML. The protocol is an infrastructure choice: swap the adapter and the spec does not change.

This section is the map. Each page says what the protocol is, how MAS-Lab implements it, which packages you install, what compliance evidence exists, and where the tutorials live.

Protocol	What it carries	MAS-Lab surface
OpenAI Chat Completions	Model calls	standard:openai and any OpenAI-compatible proxy
MCP	Remote tools	mas-library-ioa, mas-mcp
A2A	Remote agents	mas-library-ioa, mas-ctl serve
Agent Skills	Reusable instruction packs	mas-library-skills, agentskills.io
OpenTelemetry	Traces	mas-library-telemetry and AGNTCY's ioa-observe-sdk

Protocols sit in infra, not in agent logic. You can develop with local tools and local delegation, then point the same agent at an MCP server or an A2A peer. Tutorial 4 and Tutorial 5 show that split.

The landing page lists the same five protocols. Hands-on paths stay under Discover. Flag tables and YAML kinds stay under References.
