Compliance Registry is a TESSA-published A2A agent registry. Each listed firm has an A2A AgentCard carrying the TESSA Professional Services Extension (v1) — so a buyer agent can ask precise questions like "find firms offering Phase I ESAs in Virginia" or "find firms that perform WCAG 2.2 AA audits nationwide" and get structured answers.
TESSA captures every introduction request and forwards a warm intro email to the firm. Firms can request removal at any time — SLA 48 hours. TESSA is not affiliated with any listed firm unless explicitly stated.
TESSA also operates its own MCP server at
