caseforge demo: generate 83 test cases from a 3-endpoint OpenAPI spec

What it does

Four reasons engineers commit caseforge to their repo.

Pure algorithm by default

Pairwise, boundary-value, combinatorial — no LLM key needed. LLM enrichment opt-in via env var.

Multiple output formats

Hurl, k6, Postman v2.1, Markdown — committable to your repo, runnable in any CI.

OWASP API Top 10 built-in

Injection, BOLA, mass assignment, unrestricted resource consumption — covered out of the box.

MCP server for AI agents

Exposes caseforge as MCP tool — Claude Code / Cursor can drive test generation directly.
