The goal

What ECHO is trying to achieve

"Audit the operator's product for WCAG 2.2 AA conformance and produce a written report with severity-ranked findings and a remediation plan."

The capability

What it powers

The toolset

4 MCP actions ECHO can call.

Every action is exposed as an MCP server (Model Context Protocol). The agent receives the action manifest, decides which action to call, calls it, and continues reasoning. The audit trail records every call.

  • mcp.a11y.scan

    Run axe-core + WAVE + pa11y

  • mcp.screenshot.compare

    Compare to WCAG reference patterns

  • mcp.report.write

    Write the audit report

  • mcp.remediation.plan

    Generate the remediation plan

The memory schema

What ECHO remembers between calls.

  • → The audit findings
  • → The remediation plan
  • → The re-audit results
