Protocol support matrix

Agent protocols are becoming shared infrastructure: MCP now sits with the Linux Foundation's Agentic AI Foundation (AAIF), A2A connects agents to each other, AP2 covers agent payments, and x402 enables pay-per-request over HTTP. Each check below links to the page where we found the support stated.

Legend: ✓ = documented support (links to source); blank = not verified, not necessarily unsupported.
