From 74180cbace0be99241303ce530e936f444cd850a Mon Sep 17 00:00:00 2001 From: Yan Date: Mon, 16 Feb 2026 22:07:27 -0500 Subject: [PATCH 1/3] feat: add complete MCP testing suite with AI-powered analysis Major new capability: comprehensive MCP (Model Context Protocol) server testing via `nuts mcp` subcommands. This is the differentiating feature that makes nuts the first CLI tool purpose-built for MCP testing. New modules: - src/mcp/ - Full MCP client (stdio/SSE/HTTP transports), test runner with YAML-based test definitions, AI test generation, 4-phase security scanner, performance benchmarking, and snapshot regression testing - src/ai/ - Centralized AI service with provider abstraction, 15+ prompt templates for test generation, security scanning, and analysis - src/output/ - Rich terminal rendering with semantic colors, JSON syntax highlighting, test result badges, and security report formatting - src/error.rs - Unified error type with miette diagnostics MCP subcommands: connect, discover, test, generate, security, perf, snapshot 152 tests, 0 failures.

Handles markdown fence stripping. +- **`test_runner.rs`** -- YAML test file parser and assertion engine. `TestFile`/`ServerConfig`/`TestCase`/`TestStep` structs. `run_tests(path)` connects to server, executes tests, returns `TestSummary`. Supports captures (`$.field` JSONPath) and variable references (`${var}`). Human and JSON summary formatters. -- Configuration stored in `~/.nuts_config.json` -- Flow collections stored in `~/.nuts/flows/` -- API key required for AI features (security scanning, story mode, monitoring, natural language) +### AI Module (`src/ai/`) + +- **`service.rs`** -- `AiService` holds a `Box`, tracks token usage, maintains conversation buffer. Methods: `complete()`, `complete_with_system()`, `chat()`, `converse()`, `generate_test_cases()`, `security_scan()`, `explain()`, `validate_output()`, `suggest_command()`. Default model: `claude-sonnet-4-5-20250929`. +- **`provider.rs`** -- `AiProvider` trait + `AnthropicProvider`. `MockProvider` for tests. +- **`prompts.rs`** -- All prompt templates as functions. MCP-specific: `mcp_test_generation()`, `mcp_security_scan()`, `mcp_output_validation()`. API: `api_security_analysis()`, `command_suggestion()`, `explain_response()`, `natural_language_command()`, etc. + +### Output Module (`src/output/`) + +- **`renderer.rs`** -- `render_status_line()`, `render_json_body()` (syntax highlighted), `render_headers()`, `render_table()` (comfy-table), `render_error()` (what/why/fix), `render_ai_insight()`, `render_test_result()`, `render_section()`, `spinner_style()`. `OutputMode` enum: Human/Json/Junit/Quiet. +- **`colors.rs`** -- Semantic color system using `console` crate. `init_colors()`, `colors_enabled()`. Styles: success, warning, error, info, muted, accent (+ bold). JSON: json_key (cyan), json_string (green), json_number (yellow), json_bool (magenta), json_null (dim red).

Legacy code still uses `Box`. `main.rs` run functions return `Box` to bridge both. +- **AI integration**: New code uses `AiService` (one instance, shared). Legacy commands still create per-call `anthropic::client::Client`. +- **Async**: Each `run_*` function in main.rs creates its own `tokio::runtime::Runtime`. The shell creates one in `NutsShell::run()`. +- **MCP transport**: All MCP commands resolve `--stdio`/`--sse`/`--http` flags to `TransportConfig`, then call `McpClient::connect()`. +- **User data**: All persisted data lives under `~/.nuts/` (config, flows). No database. + +## MCP Test YAML Format + +Test files (`.test.yaml`) have `server:` (transport config) and `tests:` (array of test cases). See `docs/mcp-test-format.md` for the full specification.
