API Testing Platform

An LLM-driven API testing platform exposed over MCP. Tests are authored as typed, declarative defineTest/defineSuite values, compiled to a normalized JSON manifest, and executed by a pure in-house DAG engine.

Package map

Package Name Responsibility
packages/schema @atp/schema Zod schemas + inferred types — the single source of truth
packages/engine @atp/engine Pure execution engine (HTTP, assertions, DAG); no MCP/AWS deps
packages/reporting @atp/reporting ExecutionResult → Markdown / HTML / JUnit / llm_summary
packages/store @atp/store Persistence: Postgres record + queue, artifact store
packages/mcp-server @atp/mcp-server Stateless MCP server + async worker
packages/cli @atp/cli Local DX: atp compile / list / run / validate
tools/compile @atp/compile Discovery: *.test.ts/*.suite.tsdist/manifest.json
tests/ The test corpus (grows to thousands)
