Executive summary
Your eSIM-Go API scores 53.9 out of 100, which shows it is not ready for deployment. Standards compliance scored 37.4, revealing significant weaknesses in meeting required benchmarks. Documentation readiness for AI stands at 54.4, while SDK readiness for AI is slightly better at 72.5, but still needs work. Agents cannot make autonomous calls, so prioritizing improvements in standards compliance is essential for future success.

MCP Readiness
Whether your operations survive being turned into tools: distinct names, descriptions that carry what an agent must know, safe invocation semantics, auth, error recovery, and context budget

About this report. We evaluated the eSIM-Go API specification against thousands of deterministic rules we have refined over twelve years of building API tooling, supplemented by AI-based analysis. Every finding is reproducible from the spec itself, scored consistently, and paired with a concrete fix.

MCP Tools Cannot Safely Execute API
The autonomous agents cannot reliably select or call the eSIM-Go API due to missing operation identifiers and confusing operation names.
